People / Henry Wortock Air purifiers have been around for decades, both on the market and in pop culture (remember Ross’ on Friends?), though these household machines are definitely having their moment in 2022, with one even going viral on TikTok. It's safe to say that these days, we're all more aware of the air we’re breathing. Many people have taken an interest in not just cleaning and sanitizing their homes, but making sure that the air is clean as well. That’s where air purifiers come in: their goal is to remove allergens and pollutants from our home environment. Some even claim to filter VOCs and pet hair. “Anyone who suffers from breathing symptoms like nasal congestion or conditions such as allergies or asthma can benefit from using an air purifier,” says Kara Wada, MD, an assistant clinical professor of Allergy Immunology at The Ohio State University Wexner Medical Center. “People with mold or animal allergies tend to benefit the most," adds Dr. Purvi Parikh, an allergist with the Allergy & Asthma Network. Parikh explains that smoke, volatile organic compounds, and air pollution can also all be filtered through air purifiers, so whether or not you have allergies, it's a nice safety measure to add to your living space. To make sense of all the choices currently available to consumers, PEOPLE Tested put 38 different air purifiers to work — comparing the ease of setup, design features, noise levels, and more. Keep reading to learn more about the best air purifier winners below. Our Top Picks Best Overall: LEVOIT Air Purifier at Amazon Jump to Review Best Humidifier Combo: Dyson Purifier Humidify+Cool Formaldehyde at Amazon Jump to Review Best for Small Spaces: LEVOIT Core Mini Air Purifier at Amazon Jump to Review Best for Large Spaces: AROEVE MK04 Air Purifier at Amazon Jump to Review Best Quiet Mode: Bissell Air Purifier at Amazon Jump to Review Best Budget: Toppin Comfy Air C2 at Amazon Jump to Review Best with Carbon Filter: Rabbit Air BioGS 2.0 at Amazon Jump to Review Best Overall LEVOIT PlasmaPro 400S Smart True HEPA Air Purifier 4.9 View On Amazon View On Target View On Bed Bath & Beyond Pros Voice-activation via Amazon Alexa Lightweight and easy to move Very quiet, especially on sleep setting Cons None that we could find Our winning air purifier was tested by someone who isn’t new to these products — she’s a pet owner whose husband and daughter both have allergies, and she’s used an air purifier in her bedroom before. She reported that the LEVOIT Air Purifier was easy to set up, taking just four minutes from start to finish with clear and straight-forward directions. This medium-sized model is a good fit for a large room, with solid construction and an easy-to-read digital display on top. It’s also quite simple to remove the filter from the bottom when it’s time to change it out. Our tester reported that “the airflow felt great” while using the air purifier, and it was never distractingly noisy. In fact, the quiet and sleep settings were super quiet. If you enjoy multiple features on a household appliance, this model is for you. There are “loads of features on the digital display,” our tester reported, plus even more on the app, which was easy to install via a QR code. Added bonus: this model is voice-activated through Alexa as well. The app is easy to set up and it’s quite user-friendly, allowing the user to set a timer and create a schedule. The machine has handles on both sides, so you can move from room to room, and it’s very lightweight considering all it can do. As for the most important part of this product, we gave it our top ranking for effectiveness. On both the low and high settings it improved the air quality, making it cleaner than it was before our tests. We found debris on the filter (and VOCs went down in our mothball test) so we felt confident this model was doing its job. Based on its performance, we thought the LEVOIT Air Purifier had good value. Our tester said she would use it in her own home and recommend it to friends and family. Price at time of publish: $219.99 Dimensions: 10.79 x 10.79 x 20.47 inches | Weight: 12.79 lbs. | Room size: 403 sq. ft. People / Henry Wortock Best Humidifier Combo Dyson Purifier Humidify+Cool Formaldehyde 4.7 View On Amazon View On Walmart View On Best Buy Pros Highly effective even after just 5 minutes Purifying and humidifying at once ultimately saves space Helpful and high-tech digital display panel with connected app Cons While it does have a 2-in-1 function, it's the most expensive purifier on the list Heavy especially when filled with water, making it difficult to move The Dyson Purifier Humidify+Cool model packs a one-two punch with both purifier and humidifier capabilities in one machine. Set-up was fairly easy, though filling the water tank was not intuitive and our tester had to consult the manufacturer’s video for help. It’s heavy while filled with water and will take up space in your room — the signature Dyson loop alone stands about two feet tall, while the entire contraption hits the three-foot mark. The control panel on the front of the unit displays the power level of the purifier and the humidity percentage. When changing the filter, blinking lights guide the process, which was a little tricky but ultimately doable. On a low setting, the noise from this machine was undetectable, and on a high setting, it sounded like a small fan at medium speed — nice and quiet for sleeping. As for features, this two-in-one combo has an oscillating feature as well as an app, so that you can connect to all of the Dyson products in your home at the same time. The effectiveness of this model impressed us the most, clearing the air in our testing tent with impressive speed — even after running for just five minutes on high. “I would recommend this unit based on that fact alone,” noted our tester. And while she loved how effectively the unit cleared the air, and the added value of a built-in humidifier, the price tag “seems excessive,” she said. “I could purchase two units that perform these functions separately for less money. If space is at a premium then I could see paying more to have both in one unit.” Price at time of publish: $919.99 Dimensions: 36.33 x 11.02 x 12.23 inches | Weight: 18 lbs. | Room size: 400 sq. ft. People / Henry Wortock Best for Small Spaces LEVOIT Core Mini Air Purifier 4.2 View On Amazon View On Levoit.com Pros Super easy to move and transport Very quiet on the low setting High setting effectively purified the air within 10 minutes Cons Only intended for small spaces up to 178 sq. ft. Low setting isn't as efficient compared to other models Here’s a small and simple model that could be a perfect choice for someone looking to buy their first air purifier. If you’ve got a small space in mind — like a compact office or den, a baby’s room, or a hallway — this is a great option. Set-up took just two and a half minutes. With its minimalist design, this air purifier could fit into just about any aesthetic, and into any space thanks to its lightweight stature. The LEVOIT Air Purifier Core Mini is extremely quiet. “I could barely hear it [on the low setting],” noted our tester. “The highest setting was a little louder, but nothing that would be distracting.” You won’t be distracted by features, either. This is a very basic model with just three different settings: low, medium, and high. As for effectiveness, in our testing, the low setting was just mediocre. But on the high setting, the smaller LEVOIT model performed well within ten minutes. All things considered, including the low price point, “this is a steal for what it does,” said our tester. “It’s a small but mighty product. It works great — definitely worth the price.” Price at time of publish: $49.99 Dimensions: 6.5 x 6.5 x 10.4 inches | Weight: 2.2 lbs. | Room size: 178 sq. ft. People / Henry Wortock The 3 Best Humidifiers of 2023, Tested and Reviewed Best for Large Spaces AROEVE MK04 Air Purifier 4.7 Amazon View On Amazon Pros Cleans rooms up to 1095 sq. ft. Sleek design would blend in with most home decor Works quickly and quietly Cons Machine is a bit big and cumbersome to move, although still lighter than some options Doesn't include pet hair filtration Large, dusty spaces are no match for the AROEVE Air Purifiers, which are rated to help clear the air in rooms up to 1,095 sq. ft. This device features a color changing display that indicates the air quality levels of any given room: blue for “good air quality,” yellow for “moderate air quality,” and red for “poor air quality.” Though this machine is capable of filtering the air in large rooms, it doesn’t actually take up a lot of floor space itself. “It's sleek and would blend into most home decor,” our tester noted of the AROEVE air purifier, which looks like a small white box that’s not dissimilar to an oversized game console. Making use of an H13 True HEPA Filter, this air purifier quickly passed all of our tests. It significantly improved the quality of air from hazardous to safe in two to three minutes, according to our tester. This device also contains a UV filter, which AROEVE claims will purify the air further, but our tester noted that this seems a little gimmicky without evidence. While we wish this purifier also came with pet hair filtration, the sleek look, quiet noise levels, and quick purification for large spaces make this device a great choice for those with open-concept floor plans who don’t want to sacrifice good looks and great results. Price at time of publish: $129.99 Dimensions: 13.5 x 7.5 x 17.25 inches | Weight: 8.63 lbs. | Room size: 1,095 sq. ft. People / Henry Wortock Best Quiet Mode Bissell air400 Professional Air Purifier with HEPA and Carbon Filters 4.4 View On Amazon View On Target View On Wayfair Pros Noise is basically undetectable when set to quiet mode Very effectively purified the air on the lowest setting in only five minutes Cons Max setting is quite loud Expensive maintenance, with $60 filters needing to be replaced every six months Our tester was off and running with this model with its quick set-up and easy to understand digital display and buttons. We chose it as one of our top picks for its quiet setting because you can barely hear it at all. The max setting, however, is quite loud. It could be difficult to have a conversation or watch TV with it in the same room. However, there are plenty of other softer settings. The Bissell air400 has several features, including a timer that you can set to 1, 4, or 8 hours of continuous use. It’s got a filter change indicator, and a digital display that indicates low, medium, and high levels of air contamination. (We corroborated the Bissell air400’s findings with our own air quality testing device.) It’s also got a night mode that automatically turns off the machine lights and display as the room gets dark. In just five minutes on the low setting, this machine had no problem clearing the air in our test. It’s appropriate for rooms up to 432 sq. ft., which makes it a versatile option in many homes. “I was impressed that the digital display consistently matched our testing device for air quality,” noted our tester. The VOC level decreased in our mothball test as well. For how well this air purifier performed, we found it to be a good value. However, our tester did point out that filters run around $60. They also need to be replaced every six months, so maintenance is on the pricey side. Price at time of publish: $360.49 Dimensions: 16.13 x 9.75 x 24 inches | Weight: 22.82 lbs. | Room size: 432 sq. ft. People / Henry Wortock The 6 Best Pet Hair Removers of 2023, Tested and Reviewed Best Budget Toppin Comfy Air C2 Air Purifier 4.8 View On Amazon View On Toppinlife.com Pros Lightweight and portable Simple control panel that's easy to understand Purified air in 5 minutes on high setting Cons Surprisingly loud for the size, which would be noticeable in a small room This small air purifier is light in both size and price tag. It’s got a simple design with a digital control panel, giving it a sleek and modern appearance. The control panel is easy to understand without having to pull out the instructions — always a plus. On the highest setting, the noise produced by the Toppin air purifier would be very noticeable in a small room. It’s got basic features that line up with its budget price point. The Toppin has a timer, and you’ve got your choice of three fan settings on the touch control panel. You can also turn off the lights on the control panel if you want to eliminate light for sleeping. In just five minutes on the high setting, the machine was able to purify the air and improve the air quality significantly. It took 10 minutes on the low setting, but it got the job done. “I would happily purchase this in a second for my home,” our tester said. “I don’t need a fancy app with a bunch of bells and whistles. This is a great product for the price and is very easy to use.” Price at time of publish: $99.99 Dimensions: 7.6 x 7.6 x 14.8 inches | Weight: 4.5 lbs. | Room size: 215 sq. ft. People / Henry Wortock Best with Carbon Filter Rabbit Air BioGS 2.0 Ultra Quiet HEPA Air Purifier 4.7 Courtesy of Amazon View On Amazon View On Rabbitair.com Pros Uses 3 different filters: pre-filter, HEPA filter, and activated carbon filter Incredibly quiet on different settings Energy efficient with an Energy Star certification Cons Pretty large and heavy, making it less portable For heavy allergy sufferers, only effective for spaces up to 275 sq. ft. With five solid gold stars on Amazon, this air purifier from Rabbit is Energy Star-certified and (as its name implies) impressively quiet. It features three filters: one pre-filter, one charcoal-based carbon filter, and a HEPA filter to top it all off. After about 10 minutes on its lowest setting, the Rabbit Air BioGS was able to significantly improve the air quality of our testing room. Our tester liked that this device had “easy to read” settings and a timer for shutting off. “For style and ease of operation, I would buy and recommend,” our tester says. The unit is rather large, but the design has a sleek and sculptural look, so we’d probably try to pass it off as a piece of living room art. It’s also pretty heavy, so keep in mind that this might be a difficult unit to move for those who have a harder time lifting heavy things. It’s rated to be effective for spaces up to 550 sq. ft. for normal use or 275 sq. ft. for heavy allergy sufferers. Though the Rabbit Air BioGS doesn’t have a stand-alone pet hair filter, the pre-filter and HEPA filter do a pretty good job at clearing away pet hair particles, as well as pet allergens and odors. This device will be more effective in smaller spaces, but overall, our tester felt that this product was a great value for the cost (and we agree). Price at time of publish: $369.95 Dimensions: 22.2 x 16.6 x 9.8 inches | Weight: 16.8 lbs. | Room size: 550 sq. ft. People / Henry Wortock The 11 Best Pet Hair Vacuums for Sucking Up Fur, Dander, and Kibble Things to Consider Before Buying an Air Purifier Room size All of our recommended air purifiers come with guidelines for room size. If you’ve got a 350 sq. ft. bedroom, for example, you’ll want to check the specs and find a purifier equipped to handle a room that large. As for which room(s) are best to use an air purifier, that's up to personal preference. “Most often, I do suggest an air purifier in the bedroom,” Kara Wada, MD, tells PEOPLE. “The home office would be another consideration, especially with more people working from home.” Maintenance “I like to recommend that folks investigate the ongoing cost of upkeep,” says Wada. “Air purifiers are only as good as the filters they are using, so looking for a HEPA filter is important, but making sure the filters get cleaned or replaced according to the manufacturer’s instructions are also important.” For example, the filters for the Bissell Air400 cost around $60 and need replacing every six months or so — but if quiet mode and its other features are important to you, it's still worth the investment. Features Are you all about high-tech gadgets in your home? Or would you prefer a product to do its job without too many bells and whistles? (If the latter is true, we recommend the Toppin Comfy Air C2). Check the descriptions for what sort of features are included in each model. In some cases, you can save money by purchasing an effective product with simple, streamlined features. But don’t compromise when it comes to HEPA (FYI: all options on this list feature HEPA filters). Noise For every person who likes to sleep with a fan, white noise, or the sounds of the city outside their window, there’s another who needs a quiet space for sleep. Consider how loud each machine can be when set to low, high, or somewhere in between. Portability Air purifiers range in size from small to sizable space-takers. Consider the dimensions and tester notes as they relate to how you’ll use the machine. Some of our picks (including the LEVOIT Core Mini Air Purifier) are easily portable; others (such as the Rabbit Air BioGS and AREOVE Air Purifier) will require a bit more heavy-lifting. When it comes to where you should put your air purifier — they can go in a number of places, but choosing the right one can increase the efficiency of your machine. Here are some tips: place the machine near sources of air pollution; aim for three to five feet off the ground; place in any area with high airflow; and avoid corners, high humidity areas and electronic devices. People / Henry Wortock How We Tested Our testers tried out a total of 38 air purifiers. They started with timing the set-up, from the moment of opening the box, until the machine was up and running. Next they evaluated the air purifier’s design and features, as well as its noise level using a decibel meter. To test the effectiveness of each air purifier, testers set up indoor greenhouses and released a clump of pet hair and lit an incense match inside. They tested the air quality level before and after using the air purifier. The results were considered on both the low and high settings of each model, after 5 minutes, and after 10 minutes. We also used mothballs to test the effectiveness of air purifiers that claimed to filter VOCs. Finally, after evaluating all of the above, our testers learned the MSRP. Then they determined the value of each air purifier, given its price vs. the testing results. Frequently Asked Questions Which air purifier is best? Based on our testing, the LEVOIT Air Purifier was rated best overall due to its overall effectiveness, ease of setup and use, noise level, and more. Based on these tests, we believe it also provides a great value for its price (costing $219.99 at the time of publish). Do air purifiers need HEPA filters? Yes, this is the one thing that Parikh says you need when it comes to features on an air purifier. “HEPA purifiers have most studies/data with allergens, viruses, etc., so rely on those and that technology,” says Parikh. “Also, remember some things like pollen and dust mites are too small to be filtered, so you may need to take other measures for those if you are allergic.” Are expensive air purifiers worth it? The most expensive air purifier on our list is the Dyson Air Purifier Humidify + Cool, which was super effective in our testing and offers a 2-in-1 feature that not only purifies, but humidifies the air, too. If you're looking for both a humidifier and an air purifier and are particularly short on space, then this option works well and could be worth investing in. However, if you don't need the double duty, then there are air purifiers on the list that are more affordable and still effective, such as the LEVOIT Air Purifier. What range does an air purifier cover? Depending on the size of the air purifier, you can find units on the small end that cover up to 299 square feet and large ones meant to cover up to 1,900 square feet. (The manufacturer will include the ideal coverage area.) We covered a variety of unit ranges in our testing, all sizes which you can find in this list. What Is People Tested?
