The heater’s cable is 72 inches in length, making this model a good choice for rooms with few outlets; plus, the unit includes a multifunction remote control for added convenience. What to consider when buying the best space heaters There are six things you should consider to find the best space heater for your needs. Think about what type of personal heater you want, how much space you’re trying to warm, how much power your heater will need, what the safety features are, and finally, what special features might be available. If you can get specific about your requirements, you won’t have any trouble finding a reliable, long-lasting unit you’re happy with. What type of space heater best fits your needs? There are three main types of heating, with a few subcategories you should know about. Convection heating is the most common and efficient type for single-room use. These space heaters work by circulating currents across an element, such as an electric coil or oil, which are often blown out and drawn back in using a fan. Some models don’t include a fan, relying on natural airflow; this method is quieter but takes longer to heat an entire room. Ceramic heaters borrow from this method, using an internal, self-regulating ceramic element and fan to heat a room quickly. Radiant heating is excellent for warming a targeted area like your bed or desk chair. They heat up almost instantaneously using quartz or other metals and a reflector to direct heat, though some will implement a fan. Infrared heaters are very similar, using infrared quartz bulbs to generate radiating heat. Unlike convection heating, this method will not warm up the air, making it better for targeted warmth. That said, it will heat a room if left on for a long time. Micathermic heating is an efficient combination of convection and radiant processes. A micathermic heater radiates warmth off of a panel that is then circulated naturally throughout the room. To do this, these space heaters need to be reasonably large, but most models can be mounted on the wall to save space if necessary. Because micathermic heaters don’t use a fan, they are quiet and clean; they don’t circulate dust or pet dander, which makes them great for those who are allergy-prone or have asthma. Portable radiator heaters use micathermic methods to generate heat via oil encased inside. How big of a room are you trying to heat? While it’s clear that radiant heaters are best for targeted use and convection or micathermic models might be best for larger areas, there’s more to understand when it comes to room size and heater specs. When it comes to heating, wattage is king. For space heaters, you want to have 10 watts of power per square foot; this is especially true if your portable heater is the primary source of warmth. If you have super tall ceilings, over 8 feet high, you’ll want to multiply your space’s total square footage by the ceiling height and 1.25. For rooms lacking insulation, add an extra 2 watts to the equation. If you just need a little extra blast of heat here and there, you can relax on the wattage rule, but only slightly. If you have a lot of ground to cover, it can be hard to find a supplementary heater that will keep you and any guests cozy for hours at a time. Infrared heaters are a bit more flexible because they warm up people and objects; while small models won’t do much, a large infrared heater can cover a larger room because it will target objects as well as people. Below you can find our favorite model. How much energy will your space heater use? Using a space heater regularly can suck up a lot of power, so it’s essential to look for energy-efficient models that won’t cause your electric bill to skyrocket. If you want to figure out how much your heater will cost you look up how much you currently pay for electricity per kilowatt-hour (this info is often listed on your monthly bill), determine the amount of time your space heater will be on, and calculate the kilowatts used per hour by dividing the maximum wattage by 1,000. Finally, multiply all three together, and that’s your average cost per day. Unfortunately, at this time, the United States Environmental Protection Agency hasn’t given any existing space heater an Energy Star rating, but that doesn’t mean you can’t look for models with energy-efficient features. First things first: Don’t buy a space heater that has more wattage than you need. Just because it’s powerful doesn’t mean it’s the best space heater for you. Oil-filled radiator heaters are a great option for energy-efficient heating in a tinier area because they remain hot for a time, even after they are turned off. Secondly, consider investing in a model that includes a built-in thermostat and multiple output settings. This will conserve energy over time because the heater won’t be overcompensating when the temperature in the room changes. Timed heat settings and automatic shutoff can also aid efficiency, especially if you tend to forget to shut off appliances. Some heaters will come with an auto-eco setting designed to monitor room temperature and suggest a lower output temperature to heat the room, keeping it warm but not hot. What extra features make the best space heater? Once you’ve figured out the size, specs, and safety settings you need to narrow down your selection, you can focus on the fun bonuses that make the best space heater. We’ve already mentioned a few helpful features, including a thermostat function, auto-eco mode, and timer settings. Another popular bonus feature is the inclusion of a remote for easy control. This is going to be a lifesaver for those times you get perfectly comfortable, all snuggled up in bed before remembering to turn the heater on. It gets better: Some space heaters are considered “smart,” which means they can connect via WiFi to your phone, providing a stream of information regarding your space’s air quality, humidity, and more. Some smart models come with a night-time mode to quiet noisy fans, HEPA filters for air purification, and dual-cooling systems that utilize the fan function, bypassing the heat generator. Of course, the more special features you tack on, the higher the price but depending on the frequency of use and overall efficiency of various models, you could end up saving money over time. Higher-quality products experience fewer breakdowns and don’t need to be replaced as often, plus who wouldn’t want to control their space heater using a voice assistant like Alexa? One step closer to building your fully equipped smart house. What safety features should you keep in mind? We cannot overstate how important safety features are when it comes to space heaters. These powerful appliances are one of the leading causes of house fires in America, and while we want you to be warm, we certainly don’t want you to be that warm. Luckily, newer models are frequently equipped with safety features that will keep you and your loved ones out of harm’s way. You need to select a model with a shutoff sensor triggered if the unit starts to overheat or tip over. This small but significant add-on is imperative to keep things safe. You should also consider purchasing a model with a long extension cord, even if you don’t think you’ll need it. Why? Space heaters need to be directly plugged into the wall; a long cord means you can easily resist the temptation to plug it into existing power strips or extension cords for “just a minute.” Consider a model that has a cool-to-the-touch outer layer or handle so you can avoid any accidental burns. Finally, look for certifications from the Underwriters Laboratory and Intertek Group for added reassurance that your model meets safety standards. While built-in features are important, there are also a few rules you’ll have to follow: as stated, never use power/extension cords to plug in your heater; never put one on a rug or elevated surface; unless specified otherwise, you won’t want to put a space heater near the kitchen or bathroom; and keep them out of reach/away from young kids or pets. What brand best suits your needs? There are some great brands out there dedicated to supplying safe space heaters worldwide, and we certainly have a few favorites. Vornado, Dyson, and De’Longhi are staples in the space heater game. Vornado has been around since 1930 and manufactures top-of-the-line space heaters, air purifiers, fans, humidifiers, and more. Likewise, Dyson was founded in 1991 by James Dyson and, today, not only manufactures high-end home staples—such as space heaters, washing machines, robot vacuums, and blowdryers—but also invests in research projects to improve medical equipment—such as ventilators, digital monitors, and electric vehicles. The Italian company De’Longhi was incorporated in 1950 and is known for excellence in design when it comes to small home appliances such as espresso machines, portable air conditioners, dehumidifiers, space heaters, and more. De’Longhi has been the recipient of multiple awards and certifications for its dedication to high-end engineering, design, and production. FAQs Q: How much do space heaters cost? Depending on size, wattage, type of heating, and various features, space heaters can start at $30 and go as high as $600. Q: What space heater gives off the most heat? The space heater that gives off the most heat is the Dr. Infrared Portable Space Heater, which has 1,500 watts to heat larger spaces and can crank up to 85 degrees for maximum power. Q: What is the safest type of space heater? The safest type of space heater is one with tip-over protection, a cool-touch case, and an automatic safety shut-off.

Convection heating is the most common and efficient type for single-room use. These space heaters work by circulating currents across an element, such as an electric coil or oil, which are often blown out and drawn back in using a fan. Some models don’t include a fan, relying on natural airflow; this method is quieter but takes longer to heat an entire room. Ceramic heaters borrow from this method, using an internal, self-regulating ceramic element and fan to heat a room quickly.

Radiant heating is excellent for warming a targeted area like your bed or desk chair. They heat up almost instantaneously using quartz or other metals and a reflector to direct heat, though some will implement a fan. Infrared heaters are very similar, using infrared quartz bulbs to generate radiating heat. Unlike convection heating, this method will not warm up the air, making it better for targeted warmth. That said, it will heat a room if left on for a long time.

Micathermic heating is an efficient combination of convection and radiant processes. A micathermic heater radiates warmth off of a panel that is then circulated naturally throughout the room. To do this, these space heaters need to be reasonably large, but most models can be mounted on the wall to save space if necessary. Because micathermic heaters don’t use a fan, they are quiet and clean; they don’t circulate dust or pet dander, which makes them great for those who are allergy-prone or have asthma. Portable radiator heaters use micathermic methods to generate heat via oil encased inside.

How big of a room are you trying to heat?

While it’s clear that radiant heaters are best for targeted use and convection or micathermic models might be best for larger areas, there’s more to understand when it comes to room size and heater specs.

When it comes to heating, wattage is king. For space heaters, you want to have 10 watts of power per square foot; this is especially true if your portable heater is the primary source of warmth. If you have super tall ceilings, over 8 feet high, you’ll want to multiply your space’s total square footage by the ceiling height and 1.25. For rooms lacking insulation, add an extra 2 watts to the equation. If you just need a little extra blast of heat here and there, you can relax on the wattage rule, but only slightly.

If you have a lot of ground to cover, it can be hard to find a supplementary heater that will keep you and any guests cozy for hours at a time. Infrared heaters are a bit more flexible because they warm up people and objects; while small models won’t do much, a large infrared heater can cover a larger room because it will target objects as well as people. Below you can find our favorite model.

How much energy will your space heater use?

Using a space heater regularly can suck up a lot of power, so it’s essential to look for energy-efficient models that won’t cause your electric bill to skyrocket. If you want to figure out how much your heater will cost you look up how much you currently pay for electricity per kilowatt-hour (this info is often listed on your monthly bill), determine the amount of time your space heater will be on, and calculate the kilowatts used per hour by dividing the maximum wattage by 1,000. Finally, multiply all three together, and that’s your average cost per day.

Unfortunately, at this time, the United States Environmental Protection Agency hasn’t given any existing space heater an Energy Star rating, but that doesn’t mean you can’t look for models with energy-efficient features. First things first: Don’t buy a space heater that has more wattage than you need. Just because it’s powerful doesn’t mean it’s the best space heater for you. Oil-filled radiator heaters are a great option for energy-efficient heating in a tinier area because they remain hot for a time, even after they are turned off.

Secondly, consider investing in a model that includes a built-in thermostat and multiple output settings. This will conserve energy over time because the heater won’t be overcompensating when the temperature in the room changes. Timed heat settings and automatic shutoff can also aid efficiency, especially if you tend to forget to shut off appliances. Some heaters will come with an auto-eco setting designed to monitor room temperature and suggest a lower output temperature to heat the room, keeping it warm but not hot.

What extra features make the best space heater?

Once you’ve figured out the size, specs, and safety settings you need to narrow down your selection, you can focus on the fun bonuses that make the best space heater. We’ve already mentioned a few helpful features, including a thermostat function, auto-eco mode, and timer settings. Another popular bonus feature is the inclusion of a remote for easy control. This is going to be a lifesaver for those times you get perfectly comfortable, all snuggled up in bed before remembering to turn the heater on.

It gets better: Some space heaters are considered “smart,” which means they can connect via WiFi to your phone, providing a stream of information regarding your space’s air quality, humidity, and more. Some smart models come with a night-time mode to quiet noisy fans, HEPA filters for air purification, and dual-cooling systems that utilize the fan function, bypassing the heat generator. Of course, the more special features you tack on, the higher the price but depending on the frequency of use and overall efficiency of various models, you could end up saving money over time. Higher-quality products experience fewer breakdowns and don’t need to be replaced as often, plus who wouldn’t want to control their space heater using a voice assistant like Alexa? One step closer to building your fully equipped smart house.

What safety features should you keep in mind?

We cannot overstate how important safety features are when it comes to space heaters. These powerful appliances are one of the leading causes of house fires in America, and while we want you to be warm, we certainly don’t want you to be that warm. Luckily, newer models are frequently equipped with safety features that will keep you and your loved ones out of harm’s way.

You need to select a model with a shutoff sensor triggered if the unit starts to overheat or tip over. This small but significant add-on is imperative to keep things safe. You should also consider purchasing a model with a long extension cord, even if you don’t think you’ll need it. Why? Space heaters need to be directly plugged into the wall; a long cord means you can easily resist the temptation to plug it into existing power strips or extension cords for “just a minute.” Consider a model that has a cool-to-the-touch outer layer or handle so you can avoid any accidental burns. Finally, look for certifications from the Underwriters Laboratory and Intertek Group for added reassurance that your model meets safety standards.

While built-in features are important, there are also a few rules you’ll have to follow: as stated, never use power/extension cords to plug in your heater; never put one on a rug or elevated surface; unless specified otherwise, you won’t want to put a space heater near the kitchen or bathroom; and keep them out of reach/away from young kids or pets.

What brand best suits your needs?

There are some great brands out there dedicated to supplying safe space heaters worldwide, and we certainly have a few favorites. Vornado, Dyson, and De’Longhi are staples in the space heater game. Vornado has been around since 1930 and manufactures top-of-the-line space heaters, air purifiers, fans, humidifiers, and more. Likewise, Dyson was founded in 1991 by James Dyson and, today, not only manufactures high-end home staples—such as space heaters, washing machines, robot vacuums, and blowdryers—but also invests in research projects to improve medical equipment—such as ventilators, digital monitors, and electric vehicles.

The Italian company De’Longhi was incorporated in 1950 and is known for excellence in design when it comes to small home appliances such as espresso machines, portable air conditioners, dehumidifiers, space heaters, and more. De’Longhi has been the recipient of multiple awards and certifications for its dedication to high-end engineering, design, and production.

Out of the Lab and Into the Streets, Researchers and Doctors Rally for Science Against Trump Cuts

Researchers, doctors, their patients and supporters are venturing out of labs, hospitals and offices across the country to stand up to what they call an attack on life-saving science by the Trump administration

WASHINGTON (AP) — Researchers, doctors, their patients and supporters ventured out of labs, hospitals and offices Friday to stand up to what they call a blitz on life-saving science by the Trump administration.In the nation's capital, several hundred people gathered at the Stand Up for Science rally. Organizers said similar rallies were planned in more than 30 U.S. cities. Politicians, scientists, musicians, doctors and their patients were expected to make the case that firings, budget and grant cuts in health, climate, science and other research government agencies in the Trump administration's first 47 days in office are endangering not just the future but the present.“Science is under attack in the United States,” said rally co-organizer Colette Delawalla, a doctoral student in clinical psychology. “We're not just going to stand here and take it.”“American scientific progress and forward movement is a public good and public good is coming to a screeching halt right now,” Delawalla said. “It's a very bad time with all the promise and momentum," said Collins. Friday's rally in Washington was at the Lincoln Memorial, in the shadow of a statue of the president who created the National Academy of Sciences in 1863. Some of the expected speakers study giant colliding galaxies, the tiny genetic blueprint of life inside humans and the warming atmosphere.Nobel Prize winning biologist Victor Ambros, Bill Nye The Science Guy, former NASA chief Bill Nelson and a host of other politicians, and patients — some with rare diseases — were expected to take the stage to talk about their work and the importance of scientific research. The rallies were organized mostly by graduate students and early career scientists. Dozens of other protests were also planned around the world, including more than 30 in France, Delawalla said.“The cuts in science funding affects the world,” she said.She said the administration’s campaign to eliminate diversity, equity and inclusion have delayed and threatened her grant because the National Institutes of Health is scrubbing proposals with words such as “female” or “woman.” Her research focuses on compulsive alcohol use in people, which is different for men and women.The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

A leg up for STEM majors

MIT undergraduates broaden their perspectives and prospects through political science.

Senior Kevin Guo, a computer science major, and junior Erin Hovendon, studying mechanical engineering, are on widely divergent paths at MIT. But their lives do intersect in one dimension: They share an understanding that their political science and public policy minors provide crucial perspectives on their research and future careers.For Guo, the connection between computer science and policy emerged through his work at MIT's Election Data and Science Lab. “When I started, I was just looking for a place to learn how to code and do data science,” he reflects. “But what I found was this fascinating intersection where technical skills could directly shape democratic processes.”Hovendon is focused on sustainable methods for addressing climate change. She is currently participating in a multisemester research project at MIT's Environmental Dynamics Lab (ENDLab) developing monitoring technology for marine carbon dioxide removal (mCDR).She believes the success of her research today and in the future depends on understanding its impact on society. Her academic track in policy provides that grounding. “When you’re developing a new technology, you need to focus as well on how it will be applied,” she says. “This means learning about the policies required to scale it up, and about the best ways to convey the value of what you’re working on to the public.”Bridging STEM and policyFor both Hovendon and Guo, interdisciplinary study is proving to be a valuable platform for tangibly addressing real-world challenges.Guo came to MIT from Andover, Massachusetts, the son of parents who specialize in semiconductors and computer science. While math and computer science were a natural track for him, Guo was also keenly interested in geopolitics. He enrolled in class 17.40 (American Foreign Policy). “It was my first engagement with MIT political science and I liked it a lot, because it dealt with historical episodes I wanted to learn more about, like World War II, the Korean War, and Vietnam,” says Guo.He followed up with a class on American Military History and on the Rise of Asia, where he found himself enrolled with graduate students and active duty U.S. military officers. “I liked attending a course with people who had unusual insights,” Guo remarks. “I also liked that these humanities classes were small seminars, and focused a lot on individual students.”From coding to electionsIt was in class 17.835 (Machine Learning and Data Science in Politics) that Guo first realized he could directly connect his computer science and math expertise to the humanities. “They gave us big political science datasets to analyze, which was a pretty cool application of the skills I learned in my major,” he says.Guo springboarded from this class to a three-year, undergraduate research project in the Election Data and Science Lab. “The hardest part is data collection, which I worked on for an election audit project that looked at whether there were significant differences between original vote counts and audit counts in all the states, at the precinct level,” says Guo. “We had to scrape data, raw PDFs, and create a unified dataset, standardized to our format, that we could publish.”The data analysis skills he acquired in the lab have come in handy in the professional sphere in which he has begun training: investment finance.“The workflow is very similar: clean the data to see what you want, analyze it to see if I can find an edge, and then write some code to implement it,” he says. “The biggest difference between finance and the lab research is that the development cycle is a lot faster, where you want to act on a dataset in a few days, rather than weeks or months.”Engineering environmental solutionsHovendon, a native of North Carolina with a deep love for the outdoors, arrived at MIT committed “to doing something related to sustainability and having a direct application in the world around me,” she says.Initially, she headed toward environmental engineering, “but then I realized that pretty much every major can take a different approach to that topic,” she says. “So I ended up switching to mechanical engineering because I really enjoy the hands-on aspects of the field.”In parallel to her design and manufacturing, and mechanics and materials courses, Hovendon also immersed herself in energy and environmental policy classes. One memorable anthropology class, 21A.404 (Living through Climate Change), asked students to consider whether technological or policy solutions could be fully effective on their own for combating climate change. “It was useful to apply holistic ways of exploring human relations to the environment,” says Hovendon.Hovendon brings this well-rounded perspective to her research at ENDLab in marine carbon capture and fluid dynamics. She is helping to develop verification methods for mCDR at a pilot treatment plant in California. The facility aims to remove 100 tons of carbon dioxide directly from the ocean by enhancing natural processes. Hovendon hopes to design cost-efficient monitoring systems to demonstrate the efficacy of this new technology. If scaled up, mCDR could enable oceans to store significantly more atmospheric carbon, helping cool the planet.But Hovendon is well aware that innovation with a major impact cannot emerge on the basis of technical efficacy alone.“You're going to have people who think that you shouldn't be trying to replicate or interfere with a natural system, and if you're putting one of these facilities somewhere in water, then you're using public spaces and resources,” she says. “It's impossible to come up with any kind of technology, but especially any kind of climate-related technology, without first getting the public to buy into it.”She recalls class 17.30J (Making Public Policy), which emphasized the importance of both economic and social analysis to the successful passage of highly impactful legislation, such as the Affordable Care Act.“I think that breakthroughs in science and engineering should be evaluated not just through their technological prowess, but through the success of their implementation for general societal benefit,” she says. “Understanding the policy aspects is vital for improving accessibility for scientific advancements.”Beyond the domeGuo will soon set out for a career as a quantitative financial trader, and he views his political science background as essential to his success. While his expertise in data cleaning and analysis will come into play, he believes other skills will as well: “Understanding foreign policy, considering how U.S. policy impacts other places, that's actually very important in finance,” he explains. “Macroeconomic changes and politics affect trading volatility and markets in general, so it's very important to understand what's going on.”With one year to go, Hovendon is contemplating graduate school in mechanical engineering, perhaps designing renewable energy technologies. “I just really hope that I'm working on something I'm genuinely passionate about, something that has a broader purpose,” she says. “In terms of politics and technology, I also hope that at least some government research and development will still go to climate work, because I'm sure there will be an urgent need for it.”

The best portable air purifiers for 2025

Numerous studies reveal that Indoor air can be more polluted than the air outside. Air purifiers can help improve indoor air quality.

Numerous studies reveal that Indoor air can be more polluted than the air outside. Air purifiers can help improve indoor air quality. However, more powerful smart models are quite bulky and hard to transport from one room—or place—to the next. Many air purifiers for home can weigh between 20 and 30 pounds, making them difficult to move. “Portable air purifiers can help improve your home’s indoor air quality by actively reducing indoor particulate matter and airborne allergens,” says Dr. John McKeon, CEO of Allergy Standards Ltd. Since air purifiers are designed to clean the air in one room or area effectively, portability is essential if you only have one air purifier. “You’ll want it in the living room when you’re in that room and in the bedroom when you’re there,” McKeon explains. You may also want to take an air purifier—like our best overall, the TruSens Air Purifier—with you to work or when you’re visiting environments that can trigger allergies. The best portable air purifiers are not only easy to move, but they also have many of the same features (on a smaller scale) as larger models.  Best overall: TruSens Air Purifier   Best design: Smartmi Air Purifier Best value: Pure Enrichment PureZone Mini Portable Air Purifier   Best splurge: Coway Airmega AP-1512HH Air Purifier   How we chose the best portable air purifiers To compile this list of the best portable air purifiers, we conducted extensive research, contacted Dr. John McKeon and Kenneth Mendez, president and CEO of the Asthma and Allergy Foundation of America (AAFA), and did lots of first-hand testing. We wanted to provide a variety of choices, so the list is a mix of smallish, lightweight air purifiers with handles, and handheld air purifiers that can fit in a vehicle’s cup holder. We also considered peer recommendations and consumer reviews, the clean air delivery rate (CADR), recommended room sizes, filtration, and noise levels. The best portable air purifiers: Reviews & Recommendations As a general rule, the CADR is one of the most critical factors. However, if you need a portable air purifier, the CADR doesn’t really matter if the air purifier is too big and bulky to transport as needed. Some of our articles, like the best smart air purifiers, and the best air purifiers for asthma, include some models with a CADR as high as the 400 to 600 range, which is exceptionally high, considering the average “good” air purifier has a CADR in the 200 range. However, the air purifiers with the highest CADR tend to be big and bulky, so they’re not conducive to moving. So, most of the air purifiers on this list have a good CADR (when that information is available), but keep in mind that, as a general rule, a smaller air purifier isn’t going to deliver the same power as a much larger model. McKeon also says it is important to remember that an air purifier is only one part of a comprehensive approach to improving indoor air quality. “It’s most effective when used in conjunction with other strategies, such as regular cleaning, proper ventilation, and effective source control of pollutants,” he says. But you’re here to improve your environment with the best portable air purifiers, so read on. Best overall: TruSens Air Purifier  Terri Williams Pros Stylish design Handle makes it easy to transport UV, Carbon, and HEPA filtration Three fan speeds Cons No auto mode Specs Dimensions: 7 x 7 x 17 inches Weight: 8.81 pounds Recommended coverage area: Up to 443 sq. ft. CADR: N/A Noise level: 30 – 65 dB I’ve had the TrueSens Small Air Purifier for years, and it’s like an old friend I can always rely on. I have smoking neighbors and tend to use larger, more powerful air purifiers in my living space. However, I keep the TruSens Small Air Purifier downstairs in my garage, which doesn’t get as much smoke—but still a fair amount, and also experiences a variety of other smells. The air purifier does an excellent job of removing those odors and smells.  It has a three-part filtration process that includes a HEPA Type filter, a carbon filter, and a UV-C light (which I never use—it can be turned on and off). The air purifier traps dust, pet dander, smoke, and other allergen, and the bi-directional airflow quickly delivers fresh air. The air purifier has three fan speeds (including a Turbo option), providing options for letting me control the airflow and noise level. The touch controls on the top are easy to operate, and the display panel reveals the speed and lets me know when the filters need to be replaced. This is our top choice because it has an excellent price, is easy to transport, and is quite effective for the scenarios in which most people would use an air purifier. It also has a sleek and space-saving design and is lightweight enough to grab by the handle and move from room to room or even toss in your car and carry to work or other locations. TruSens also makes this air purifier in medium and large sizes, and those models include additional features, like real-time air monitoring, washable pre-filter, timer, and additional fan speeds. Best design: Smartmi P1 Air Purifier Terri Williams Pros App Voice control Dual-laser particle sensor Leather strap Choice of filter Cons Have to turn it upside down to replace the filter Specs Dimensions: 11 x 11 x 17 inches Weight: 3 kg Recommended coverage area: 180 to 320 sq. ft. CADR: 250 Noise level: 19 – 49 dB At first glance, the Smartmi P1 Air Purifier looks like a knockoff of the Molecule Air Mini+ air purifier, which also has a leather strap. However, the Molecule Air Mini (which costs twice as much) only has a small leather strap on the side (with space for one or two fingers), whereas the Smartmi P1 has a stylish leather strap across the entire top. I’ve tested the Molecle, and the Smartmi strap feels much sturdier and doesn’t put all the weight on one or two fingers. The Smarti has a great design overall and is certainly one of the best-looking air purifiers on the market, But that’s not the only reason it gets our best design award. The Smartmi P1 also offers a choice of 2 filter types. The Pollen filter is a good choice for those who suffer from seasonal allergies. There’s also a Pet Filter that’s helpful if you have furry friends in your home. Both filters contain a True HEPA filter, preliminary filter for large particles, and carbon/inner filter, and can remove dust, smoke, pet dander, and other allergens. The touch controls and LCD monitor are on the top and include a dual PM 2.5/PM 10 particle sensor to capture both small and large particles in the air. The air purifier has a timer as well. Since it’s a smart air purifier, I can control it via smartphone or voice control.  Best value: Pure Enrichment PureZone Mini Portable Air Purifier   Terri Williams Pros Fits in vehicle cup tray Several color choices Rechargeable battery Three fan speeds Sits horizontally or vertically Cons Only for a personal bubble Specs Dimensions: 3.3 x 8.5 x 2.7 inches Weight: 0.6 ounces Recommended coverage area: 54 sq. ft. CADR: N/A Noise level: Up to 50 dB If it’s possible for an air purifier to be fun, the Pure Enrichment PureZone Mini Portable Air Purifier certainly is. It’s about the size of a 12-ounce soft drink and fits in my car’s cup holder. It’s also small enough to toss in my handbag or suitcase. When traveling, this air purifier allows me to purify the air when I’m in a hotel room or staying with family members or friends. And the fact that it’s battery-operated means I can use it literally everywhere. Although it’s small, the PureZone Mini works well. It has a dual HEPA filter that also includes an activated charcoal filter. The device has three fan speeds, but you must remember that the higher the speed, the quicker the battery runs out and needs to be recharged. The air purifier filters everything from dust to smoke to pollen and pet dander. One of my favorite features is the adjustable handle. This allows me to stand the device upright or tilt it on the side so it can be used vertically or horizontally. And when it’s hot, the air purifier also doubles as a small fan, providing both purified and cool air. Best splurge: Coway Airmega AP-1512HH Air Purifier Terri Williams Pros Smartphone control Lightweight Voice control Real-time air-quality indicator Cons Bulky compared to others on this list Specs Dimensions: 18.3 x 9.6 x 16.8 inches Weight: 12.3 pounds Recommended coverage area: up to 1,575 sq ft CADR: 221 Noise level: 24 – 53 dB While not necessarily an expensive air purifier (we’ve tested models that cost well over $1,000), the Coway AP-1512HH Air Purifier is the most expensive model on this list, which is why it’s our splurge choice. It can cover up to 1,474 sq. ft., and we think this model is a good portable choice for large rooms. The air purifier is easy to operate and the filtration system includes a pre-filter, True HEPA filter, and a Fresh Starter deodorizer filter, so it can capture both larger and smaller particles while also removing cooking and tobacco odors. The user-friendly control panel on the top lets me view real-time air-quality data, and the color-coded indicators turn blue when the air is fresh and clean, yellow when it’s problematic, and red when the air is unhealthy. There are five speeds, and when the air purifier is in auto mode, the fan will automatically increase or decrease depending on the air-quality indicator data. I can also set the timer for 1, 4, or 8 hours. The filter replacement light (one for the HEPA filter, one for the deodorizer filter) comes on when one of the filters needs to be replaced. What to consider when buying the best portable air purifiers There are several factors to consider when deciding which portable air purifier is right for you. When writing this guide, these are the factors we considered most important.  Room Size An air purifier may be effective in a smaller room but less effective in a larger room. That’s why we included the recommended room size for each air purifier on our list. Ensure you’re not expecting the air purifier to clean more space than it’s recommended to handle. CADR   For air-cleaning effectiveness, McKeon says selecting the correct Clean Air Delivery Rate (CADR) for the room size is vital. “This is an important metric, which indicates the volume of filtered air an air cleaner can deliver, with separate scores when the device was tested with smoke, pollen, and dust challenges.”  (Note: Some manufacturers combine the scores for smoke, pollen, and dust and just list the average CADR rating of the three tests.)  “A higher CADR means the device can filter more particles,” McKeon says. Filtration Filtration is another important factor to continue, and the presence of a HEPA filter is always a good sign. “HEPA stands for High Efficiency Particulate Air,” Mendez explains. “These filters are media-based, meaning that they are physical filters, which capture particles as air passes through them, and HEPA filters are designed to filter out at least 99.7 percent of particles of 0.3 microns or larger diameter,” he says.  Smart Smart features can make the air purifier easier to operate. For example, some models have an app, so you can control it using your smartphone and even issue voice commands. Other smart features include the ability to auto-detect the level of air purification needed and adjust the airflow accordingly. FAQS Q: How do air purifiers work? “Portable air purifiers function similarly to whole-home systems, but they are designed to clean the air in a specific room,” McKeon says. “They draw air in and pass it through specific filters to remove airborne pollutants, and. they’re often used to address specific areas, like rooms most affected by smoke, or bedrooms where people can spend lots of time.” Q: Where is the best place to put a portable air purifier? “When determining where to place a portable air purifier, you should consider the rooms in the house where you spend the most time,” Mendez says. “This may vary throughout the day, so, you may place the air purifier in a home office during the day and then move it to your bedroom while sleeping.”  Q: Do portable air purifiers work for COVID and other airborne viruses? “According to the Environmental Protection Agency (EPA), when used properly, air purifiers can help reduce airborne contaminants, including viruses in a home or confined space,” Mendez says. “However, by itself, a portable air cleaner is not enough to protect people from COVID-19.” Q: Can air purifiers help with allergies? “Yes. Air purifiers can be a useful tool for reducing exposure to common allergens such as pollen, mold, and pet dander,” Mendez says. McKeon agrees. “Air purifiers can play a key role in helping to manage allergies by removing airborne allergens, such as pet dander, pollen, mold, and dust mite allergen from the breathing zone,” McKeon says. Q: Is it OK to sleep with an air purifier running? Yes. It is generally safe to sleep with an air purifier running. You should always pay attention to the manufacturer’s recommendations for information on how long to run your purifier and where to place it,” Mendez says. “When properly used, an air purifier can help improve the air quality where you sleep.” Final thoughts on the best portable air purifiers Best overall: TruSens Air Purifier   Best design: Smartmi Air Purifier Best value: Pure Enrichment PureZone Mini Portable Air Purifier   Best splurge: Coway Airmega AP-1512HH Air Purifier  An air purifier can only be beneficial to you if it’s in the same room where you’re residing.
