How We Picked the Best Air Purifiers

Most standard air purifiers today work with high-efficiency particulate air filter technology (HEPA filters) to remove up to 99 percent of potentially harmful particles found in the air we breathe. These types of filters were introduced in the 1950s after being employed by the United States' Manhattan Project to control airborne radioactive contaminants — which means they should be more than equipped to disinfect the air you breathe around the house. With this in mind, air purifiers perform optimally in conjunction with regular maintenance and keeping a clean home.

In evaluating the models that made our list, we chose primarily trusted brands with decades of name recognition among consumers. We reviewed approximately two dozen of the best air purifiers before narrowing down to our five picks, based primarily on customer ratings and reviews. Not a single product on this list received less than a 4.5-star rating — because we take your respiratory health very seriously, and the products we chose should reflect that.

As such, filtration systems were another factor we honed in on. Nearly all of the products featured HEPA-style filtration systems or came very close in the efficiency of air quality output. Ease of filter replacement was another critical consideration. Not only did we want to ensure that these air purifiers had replacement filters that were easy to swap out, but that the replacements were likewise either affordable or had comparable aftermarket options.

With the wrong product, you otherwise may find yourself doubling or tripling the initial cost of your investment in replacement filters — possibly within months if you aren’t careful.

The Best Air Purifiers: Reviews & Recommendations

Best Overall: Dyson Pure Cool Link TP02 Air Purifier

Dyson Pure Cool Link is the best air purifier
Dyson Pure Cool Link is the best air purifier

Why It Made The Cut: Create a cleaner, healthier home with a purifier scientifically proven to capture the tiniest particles as small as allergens and bacteria.

Specs:
— Weight: 7.9 pounds
— Power Source: A battery
— Coverage Area: Up to 300 square feet

Pros:
— Doubles as a cooling fan in summer
— Dyson Link app provides real-time air quality reports
— Attractive modern design

Cons:
— Noisy operation on higher settings
— Costly replacement filters

Keep your home cool in warmer months while removing impurities from the air all year round with the Dyson Pure Cool Link TP02 Air Purifier. The 360-degree, vacuum-sealed glass HEPA filter removes 99.97 percent of allergens and pollutants, including pollen and bacteria as small as 0.3 microns, which works with an additional layer of activated carbon to capture household odors and potentially harmful toxins such as paint fumes.

Intelligent purification automatically monitors, reacts, and purifies the air you breathe and then provides real-time air quality reports to the Dyson Link app. This way, you can remotely control your environment from your smartphone, even when not at home. Though some folks find the daily operation of this Dyson air purifier to be rather loud, it does feature a nighttime mode that uses the quiet settings, and the LED display dims to ensure light sleepers won’t be disturbed. Replacement filters are easy to change, compared to some models that require filters to be washed every month or so. According to the manufacturer’s specs, filters are intended to be replaced once per year, based on the average use of 12 hours per day. However, some budget-conscious consumers find that the filters must be changed more frequently and tend to be very expensive, on top of the pricey cost of the air purifier alone.

Best for Allergies: Blueair Blue Pure 211+ Air Purifier

Blueair Blue Pure211 is the best air purifier
Blueair Blue Pure211 is the best air purifier

Why It Made The Cut: An activated carbon filter reduces and eliminates gases and odors from pets, smoking, cooking, wildfires, volatile organic compounds, and more.

Specs:
— Weight: 13 pounds
— Power Source: Corded electric
— Coverage Area: Up to 540 square feet

Pros:
— Washable fabric pre-filter
— One-button control
— Low energy consumption

Cons:
— Filter is technically not HEPA-grade
— Large, round holes on the top may be unsafe for kids

Capture over 99 percent of airborne pollutants, including viruses, pollen, dust, pet dander, mold, bacteria, and more, with the Blueair Blue Pure 211+ Air Purifier. Filtering the air at a rate of approximately 4.8 times an hour, or about every 12.5 minutes, it’s the perfect way to effectively lower particle levels in sensitive areas you need the most, such as living rooms, family rooms, and playrooms.​ The activated carbon filter also reduces and eliminates gases and odors, so the air in your home will likewise smell fresh and clean while it purifies.

The washable fabric pre-filter offers the first layer of protection by catching larger contaminants from the air. At the same time, the particle filter captures charged airborne germs and allergens that stick to the filter media. Then, when it’s time to replace the filter, the single-button control alters you without the need to adjust settings and knobs. Instead, a built-in warning system glows red when it's time for a change. It also runs pretty quietly at a sound level of 31 to 56 decibels and an Energy Star-rated consumption of 30 to 61 watts. While the machine boasts an attractive design, parents of young children and pet owners may want to take note of the large holes on top, which are just big enough for tiny fingers or paws to get stuck. Another possible downside is that the filter is technically not HEPA-grade, so if you live somewhere with especially poor air quality, you may want to hold out for HEPA technology.

Best for Large Rooms: Coway Airmega 400 Smart Air Purifier

Coway Airmega is the best air purifier
Coway Airmega is the best air purifier

Why It Made The Cut: Cleans the air you breathe faster and more efficiently with a double suction system that provides up to an impressive 1,560 square feet of coverage for large rooms.

Specs:
— Weight: 24.7 pounds
— Power Source: Corded electric
— Coverage Area: 1,560 square feet

Pros:
— Trap airborne particles as small as 0.01 microns
— Three-setting smart mode
— Whisper-silent quiet operation

Cons:
— Filter health button resets too easily
— Very heavy and cumbersome to move around

Designed to accommodate large room sizes up to 1,560 square feet, the Coway Airmega 400 Smart Air Purifier cleans the air at least twice per hour with an expert three-stage filtration system. The pre-filter catches contaminants such as hair and large dust particles, while the Green True HEPA filter combined with activated carbon traps 99.99 percent of fine airborne particles up to 0.01 microns in size and removes unpleasant or harmful fumes and odors.

You’ll know how the filters are working every minute of the day, thanks to a pollution sensor that communicates indoor air quality testing in real-time with a brightly colored LED ring. Likewise, the five-setting fan speed automatically adjusts based on the room’s air quality and lighting conditions, from smart, sleep, low, medium, and high. As a result, the noise level is practically silent at lower speeds, with it topping out at 43.2 decibels at its highest setting. Again, the only downside for children and pet owners to be aware of is that the filter health button has a hair trigger that’s easy to reset, causing the unit to think that the filters have been recently cleaned. Some users have remedied this by placing a small thin piece of plastic over the buttons. Another issue to be aware of when you're looking for the best air purifiers is that the machine is very large and cumbersome and may require two people to move it.

Best Design: Coway Airmega Icon

Coway Airmega Icon is one of the best designed air purifiers.
Coway Airmega Icon is one of the best designed air purifiers.

Why It Made The Cut: Form and function come together in the Coway Airmega Icon, whose award-winning design doesn't sacrifice an ounce of air-purifying power.

Specs:

— Weight: 19.2 pounds
— Power Source: Corded electric
— Coverage Area: Up to 649 square feet

Pros:
— Award-winning design 
— Water and stain repellent fabric 
— Doubles as a wireless device charger 

Cons:
— Pricey

The Coway Airmega Icon was developed in partnership with industrial design firm Fuseproject, and it totally shows. At just over 22 inches tall, it tucks away into any space, but its form and function will fit into any room’s aesthetics. 

Along with just plain looking great, the Airmega Icon packs tons of power into its small space. This single device cleans a space up to 649 feet continuously. The 24/7 pollution manager keeps track of the air quality and adjusts the purification levels to conserve energy when the air is cleaner. Instead of buttons, operating the device is done by an easy touch display, which blends seamlessly into the design. Six lighting and three fan settings offer tons of customization possibilities for whatever room or space you park the Coway Airmega Icon. All this power and the noise level don’t get louder than a ticking watch on its lowest setting. The top plate even doubles as a wireless charger for any Qi-compatible device. Plus, the neutral-toned fabric that lines the device is both water and stain repellant, so your Airmega Icon remains clean and beautiful for years to come. It’s pricey for sure but think of it as a long-term investment in air quality and brilliant home design. 

Best for Small Room: Honeywell HPA100 HEPA Air Purifier

Honeywell HPA100
Honeywell HPA100

Why It Made The Cut: Whether you have pets, allergies, or just stale indoor air, this purifier for small rooms will help deliver cleaner, fresher air so you can breathe easier.

Specs:
— Weight: 8.52 pounds
— Power Source: Corded electric
— Coverage Area: 155 square feet

Pros:
— Four air cleaning levels
— Turbo Clean setting
— Allergen Plus series

Cons:
— Replacement filters are expensive
— Touch-based buttons are not intuitive

Provide cleaner, fresher air for small to medium-sized rooms up to 155 square feet such as bedrooms and nurseries with the Honeywell HPA100 HEPA Air Purifier. It comes with a HEPA filtration system that captures up to 99.97 percent of microscopic airborne allergens and particles. Dust, pollen, pet dander, dust mite debris, and smoke are no match for the four different cleaning levels that circulate air 4.8 times per hour, including the Turbo Clean setting for the toughest filtration jobs.

As part of Honeywell’s Allergen Plus series, the purifier earned the Energy Star label by meeting strict energy-efficient guidelines set by the United States Environmental Protection Agency. For best performance, Honeywell recommends using only the company’s proprietary air purifier filters and that compatible aftermarket filter replacements are not guaranteed to offer the same performance or efficiency. However, many customers have found that third-party filter and pre-filter replacement kits provide the same, or a similar performance, for a lower price. Another minor gripe among user reviews is that the buttons on the unit are touch-based and not intuitive, which tend to break faster and have more issues than mechanical buttons or interactive touchscreens.

Best Smart: Mila Air Purifier

Mila Air Purifier
Mila Air Purifier

Why It Made The Cut: If you don't want to worry about futzing with different settings, Mila is one of the best air purifiers that will keep the air in your apartment cleaner without you having to lift a finger.

Specs:
— Weight: 18 pounds
— Power Source: Corded electric
— Coverage Area: 1,000 square feet

Pros:
— Understated design
— Can be controlled via an app
— Supports multiple types of filters

Cons:
— Replacement filters are expensive
— Can be very sensitive

In our experience, many "smart" appliances, gadgets, and accessories are more trouble than they're worth, Mila Air Purifier is a welcome exception to that rule. Instead of overwhelming you with too many options, or asking you an overabundance of questions, the Mila basically works right out of the box. You'll need to download an app and create an account, but the only thing the air purifier needs to know is whether you live in an urban or suburban environment and the relative size of your room. From there, it'll run a 60-second diagnostic to test the quality of the air around it, and silently get to work filtering the rest.

Mila bundles its air purifier with a "high-performance filter," that's designed to handle smoke, allergens, dust, pollution, and pet dander. The company offers additional filters designed to specifically target certain pollutants, but the high-performance one is a good catch-all. Mila recommends you switch out the filter every six months or so, which is what we've done. What makes Mila's Air Purifier special is its hands-off approach. The purifier's automatic mode will automatically adjust the speed of its fans based on the level of pollutants in the air. Generally speaking, the automatic mode has been so silent that we haven't had to turn it off at night. The fans have kicked into high gear when the window was opened (that's New York City for you), or when we've left the bedroom door open while cooking. In those instances, the purifier's fans can get a little grating, but it's a sign that it's doing its job. This is something to keep in mind if you plan on keeping the air purifier in an open space with a lot of foot traffic or activities.

If you've put off getting an air purifier because of how annoying it is to manage (who really knows the difference between the low, medium, and high settings?), we can confidently recommend Mila's. It's one of the few pieces of smart-home gear that's worked so well that we've never thought about replacing it.

Best Affordable: Holmes Desktop Air Purifier

Holmes Desktop Purifier
Holmes Desktop Purifier

Why It Made The Cut: The slim design is ideal for small rooms up to 109 square feet and can be placed vertically or horizontally anywhere, such as a table or desktop.

Specs:
— Weight: 5.7 pounds
— Power Source: Corded electric
— Coverage Area: 109 square feet

Pros:
— Three different speed settings
— Optional air ionizer
— Dual positioning design

Cons:
— Bulkier than a tower-style air purifier
— Not the most attractive unit

Perfect for everything from dorm rooms to offices, the Honeywell HPA100 HEPA Air Purifier is best suited to improve the quality and freshness of a 10- by 11-foot room; or a total of 109 square feet of space. With three power settings, you can optimize the speed depending on your immediate needs. Simply select a lower speed while you're at home for continued purification with less noise or a higher speed while away for maximum cleansing. Sliding switches control the power settings for ease of use, and the filters can be accessed through a pop-off cover.

To help clean air even more thoroughly and tackle tough odors, the unit comes with an optional air ionizer that binds negative ions to airborne smoke, dust, and pollen to form larger particles that can be captured more easily. In addition, the dual positioning slim design allows the unit to be placed vertically or horizontally to best fit your space, such as on a table or desktop. However, even with the dual positioning design, some users find the air purifier bulkier than standing or tower options. It’s also not the most attractive unit compared to higher-end competitor brands, but you certainly can’t argue with the affordable price.

Best Premium: Coway Airmega 250S App-Enabled Smart Air Purifier

Coway Airmega 250S is the best premium air purifier.
Coway Airmega 250S is the best premium air purifier.

Why It Made The Cut: Coway Airmega 250S is one of the smartest and most gorgeous air purifiers, as long as you can afford it.

Specs:
— Weight: 20.5 pounds
— Power Source: Corded Electric
— Coverage Area: Up to 930 square feet

Pros:
— Powerful and fast
— Easy filter care 
— Monitor air quality and filter status from the mobile App

Cons:
— Incredibly expensive 
— Rattles when the fan is set to the highest speed

The Coway Airmega 250S is seriously smart and is gorgeous enough that it could qualify as a centerpiece. And like plenty of room centerpieces, you can expect to pay top dollar for it. 

Of course, the price tag may be well worth it, considering it’s incredibly powerful. It can clean a space up to 930 square feet, and more importantly, it can do it fast. A colored LED bar monitors air quality in real-time, from very unhealthy red all the way to clean and breathable blue. Of course, if you blink, you might miss it changing colors, as the Coway Airmega 250S works its air-purifying magic lightning fast. With three fan speeds, the device adapts to surroundings, rotating fast when levels are unhealthy, and rotating slowly while you sleep. Its Green True HEPA filter traps 99.99 percent of airborne particles up to 0.01 microns, volatile organic compounds like cooking smoke, and even smelly odors. And with the Coway Airmega 250S EZ release design, you’ll actually remember to clean and replace your filter. Still, the price tag is still a hard pill to swallow, but for those who suffer from serious indoor allergens, Coway Airmega 250S is less a machine and more of a miracle worker, even if it does rattle lightly when the fan is set to high speed. 

Things to Consider Before Buying the Best Air Purifiers

Suppose you’re considering a home air purifier to help you Blueair Blue Pure 211+ Air Purifier, odors, and other airborne particles from your living space. In that case, the first thing you need to determine is what part of your house most needs to improve air quality. Then, you can choose an air purifier that best fits the space. For example, in a bedroom, you may need only an air filter that accommodates a capacity of only a hundred or a couple of hundred square feet. However, for an ample living space or open area floor plan, you’re going to be looking at any option that can tackle over a thousand square feet, or perhaps even a few units working in tandem with one another.

The second thing that you should determine when looking for the best air purifiers is what type of air pollutants you are looking to clean out of your home. If you suffer from pet or seasonal allergies, you can probably get away with a lower-end model to help you breathe and sleep easier. However, for people living with asthma or those who need high-performance air purification — such as anyone living in places where wildfires or other types of pollution are an issue — then you are going to want to go with something that traps even the finest dust and bacteria particles.

If your primary requirement for purchasing an air purifier is to reduce or eliminate smells and odors, you’ll want to check that the filter comes with an additional filter or layer of activated carbon built into the filtration system.

FAQs

Q: Will an air purifier kill the coronavirus?

When used properly, the best air purifiers can help reduce airborne contaminants, including even some bacteria and viruses in a home or confined space. But a portable air cleaner is not equipped to kill the SARS-CoV-2 virus on its own.

Q: Should I leave the air purifier on all day?

For best practices to eliminate or reduce the air pollution in your home, it’s best to leave your air purifier on all day. Fortunately, there are no foreseen drawbacks to keeping your unit running all the time. However, it’s imperative to change the filters regularly, when they need to be replaced, to keep your air purifier running as optimally and efficiently as possible.

Q: Where is the best place to put an air purifier?

The best place to put an air purifier is near a window, doorway, or other high-traffic areas that produce a lot of airflows. The reason for this placement is that the moving air can cause dust, mold, and other particles to lift off surfaces and distribute around your house.
