The Best Air Purifiers of 2021

The Sharp FPK50UW is a sleek but powerful air purifier featuring three fan speeds (including a “Sleep mode”) and a “Express Clean” option that uses ionized particles to remove contaminants from the air for up to 60 minutes. The “Express Clean” setting cleared kitty litter dust from the air with no problem, but had a bit of a tougher time removing the smell of bacon from the air.

With its small size, low weight, and deep handle, this air purifier is very portable.

The Wynd Home Purifier has four fan modes and is big enough (and powerful enough) to quickly clean the air in a larger room or multiple rooms arranged in an open floor plan.

The Wynd Home Purifier dispatched bathroom smells and burnt toast with ease. However, the Wynd struggled a bit when it came to fragrance smells.

Only the fastest fan speed is noisy, but again, that’s to be expected. While its size makes it a bit awkward to handle, with its relatively low weight and side handles, it’s pretty easy to move and lift.

Beneath its industrial-looking exterior lies an air purifier that can get the job done. The Blueair Classic 205 has a basic control panel only consisting of the power/fan control, the WiFi network indicator, and the filter status light.

The Classic 205 had a tough time removing cigarette smoke, but it did a pretty good job of cleansing the room of the stench of fish oil, so we'd recommend using this air purifier near the kitchen so as to help eradicate unpleasant cooking, food, or food waste smells. At-home testing revealed that the Classic 205 might also help to mitigate allergy congestion when you first wake up in the morning.

Some of its settings can be a bit loud.

The Bissell air220 is intuitive and unobtrusive. It has a single power button and five fan speeds, a tiny display panel that shows the fan setting, and three different LEDs give you general information about the ambient air quality. The air220 is designed to fade into the background, rather than draw the eye.

The air220 did a solid job of getting rid of pot smoke, but it struggled a bit more to remove the smell of incense. In our lab, it performed similarly, where it wasn’t quite able to dispel the smell of peppermint from our sealed test room after running for four hours.

The fastest fan setting isn’t too loud, and it automatically switches over to night mode and turns off the machine lights when it senses low ambient light levels. The Bissell has a nice cord storage system, but the too-shallow handle means that you have to hold it with two hands when moving it around.

The Vornado AC550 favors simplicity over aesthetics. It's interesting to look at, if not particularly modern in its design. With only a plus and minus sign button to toggle between the four fan speeds, sleep, and auto modes, and filter status lights, this air purifier is for those who don't want to read an entire manual in order to understand how to make it work.

The Vornado had a tough time removing the scent of a peppermint essential oil, but did well with fish oil, so it may be more successful in removing food and cooking smells. While some of the settings on the Vornado are loud, most are quiet enough that they weren't bothersome during quiet time or conversations.

The Vornado is light, and can be moved with one hand, using one of the pocket handles on the side of the machine. It is a device that you don't have to babysit.

The Honeywell HPA200 is one of the more basic air purifiers on the market, but it is effective and user-friendly. While its interface is simple, it has four different cleaning modes and offers enough flexibility that you'll be able to use it in a number of different circumstances, particularly when pollen is bad or when family members get sick.

Other features include a timer, filter status lights, and a dimmer function that allows you to adjust the level of panel lighting as needed.

While the HPA200 did a pretty good job of filtering out fish oil, it had a tougher time removing the lemon essential oil smell from our test room. The HPA200 will also drastically reduced the number of airborne allergens.

However, some settings get pretty noisy, so you may have to either use the timer function or run it on a lower setting if you want to run it while sleeping.

The Blue Pure Fan has a stylish aesthetic and a simple control panel consisting of a single button that you press multiple times to access the different fan speeds. The fan speed LEDs change to yellow when it’s time to replace the particle filter.

Despite it lacking a HEPA filter, the tester reported that this cooling fan noticeably reduced pet odors and cooking smells, and also made her home more livable for a roommate with a dust allergy. In the lab, we found that the Blue Pure Fan did a pretty good job of dispelling the smell of fish oil.

The highest fan setting is loud, but it’s easy to move around.

The Blue Pure 211+ is among the most streamlined and eco-friendly products we tested, featuring a washable fabric prefilter, a reusable metal frame that houses the particle filter, and the most basic control panel ever.

One large, central button means you tap it repeatedly to increase the fan speed, respond to filter replacement reminders, and turn the machine on and off.

The Pure 211+ did pretty well in our smell tests, removing the smell of fish oil better than it did the scent of lemon, so this air purifier is probably better for people who are plagued by cooking smells, rather than fragrances. Slow-cooker smells, while enticing for some, are no match for the air cleaning power of the Pure 211+.

It's also surprisingly light, so it's easy to move to another room.

Despite its old-school aesthetics, its interface and capabilities are both modern and highly relevant to today's air quality concerns. In addition to the cleaning modes, this air purifier also has a VOC sensor, which, when activated, automatically sets the level of air cleaning to best eradicate any VOCs detected.

Even better, you can connect with your device via Bluetooth allowing you to change the settings, set alerts for allergen levels, order filter replacements, and set a weekly operation schedule.

在过滤HPA250B做了一个很好的工作the smell of the nutmeg essential oil but did not perform as well when it came to filtering out cigarette smoke. Testers who took the Honeywell home noticed a definite improvement in their air quality with respect to the rapid removal of cooking smoke and smells.

While some of the fan settings get pretty loud, this is offset by the fact that you can set a very specific schedule for it to follow.

This combination of air purifier, heater, air conditioner, and fan has so many features and options that it'll make your head spin.

You can use the Dyson app to monitor your air quality, change the settings, and check on the status of the filters. With its magnetic remote and display screen, you can easily toggle between modules that allow you to check indoor air quality, humidity, temperature, and VOC content, among other things.

While the Dyson Pure Hot + Cool didn't do as well in our smell tests as other air purifiers. During the smell test, the air purifiers ran for four hours, and because of a smaller outflow grill it took it longer to purify the air in the room. Those who tested the Dyson in their homes reported that their air felt fresher and that it did a solid job of improving their air quality.

This is a great machine if you want the best out of an all-in-one air conditioning device.

The Airmega's streamlined control panel has large buttons that are easy to press. Its five fan modes include "Auto" (which turns on when the air quality gets below a certain threshold) and "Eco" (which turns off automatically when no pollutants are detected after 30 minutes).

In the Coway IO Care app (iOS/Android), you can control your device, get real-time air quality data, and set up air quality notifications.

Note: the smart aspect of this air purifier only works on 2.4 GHz wi-fi networks, so if you only have a 5 GHz network in your home, you may not be able to take advantage of the Coway’s smart features.

It does a great job of getting rid of cooking smells such as ground beef, popcorn, and garlic. It struggles a bit more removing fragrance smells such as fruit-scented candles and peppermint oil. The faster fan settings are pretty loud. It also has a convenient handle on the back and easy access to the filters.

The industrial looking 480i can be controlled remotely via the Blueair app and has filter status lights on its hidden control panel. It has bigger, stronger air fans, and warning lights for high contents of VOCs and PM2.5 particulate matter.

When it came to the smell tests, the 480i was one of the better devices when it came to removing fragrance smells—peppermint in particular. It did, however, struggle when it came to cigarette smoke. At-home testing revealed the utility of the app, which shows the air quality in real time.

The high fan speed is loud, but the other fan speeds are quiet enough to not prove disruptive to sleep or conversation. Lastly, it is heavy and awkward to move, even if its rectangular shape lends itself to easy storage.

The Blue Pure 411+ is a way for people to explore the possibility of cleaner air without spending a lot of money. Between its small size and its futuristic, cylindrical design, it’s easy to fit into any home.

Our tester subjected it to sweaty workout clothes and the smell of cooked onions, both of which the Blue Pure 411+ handled pretty well. It had a tougher time removing cigarette smoke, and in fact, vented out air with a smoky odor.

The fastest fan setting is loud, but not as loud as some of the larger air purifiers we tested. While the Blue Pure 411+ lacks a handle, it’s light enough that you can simply pick it up and move it as needed.

The Rabbit MinusA2 has a lot of useful and fun customization options. In addition to its five fan speeds, it also has an “Auto” mode, and a “Pollen” mode that can sense pollen and turn off automatically once the air has been cleansed. The Rabbit MinusA2 has also been certified by theAsthma and Allergy Foundation of America。In addition to all the usual filters, the Rabbit also allows you to insert one of four possible custom filters: Toxin Absorber, Germ Defense, Pet Allergy, and Odor Removal.

The Rabbit Air app (iOS/Android) is pretty robust; you can control every aspect of operation, as well as set a timer or a schedule for when the device will turn on or off.

Note: The smart aspect of this air purifier only works on 2.4 GHz wi-fi networks, so if you only have a 5 GHz network in your home, you might not be able to take advantage of the Rabbit’s smart features.

During at-home testing, the Rabbit did a pretty good job of removing cooking smells and pot smoke from the air. It also almost completely removed all traces of the fish oil that had been planted inside our sealed testing room.

While the Rabbit has a nice deep handle, it’s a bit heavy.

If you've ever wondered what it would look like if Apple designed an air purifier, look no further than the Alen BreatheSmart 75i. Its clean lines and sleek interface will definitely appeal to those who spend a lot of time on their smartphones. The control panel is streamlined and fairly intuitive, with the buttons for the fan speed, timer, filter status, and optional ionizer clearly labeled. The circle around the unit's power button changes color to indicate the overall air quality in your home.

During smell testing, the Alen did a pretty good job of diffusing the smell of a cinnamon fragrance, so it'll be a good fit for those who have to contend with smells from spray bottles, such as cleaning solutions and perfumes. It also did a pretty good job of getting rid of the smell of fish oil, so it can conquer cooking smells as well. Some of the fan settings can get pretty loud.

While the Alen comes with a pocket handle and wheels, it's still pretty tall and heavy.

This modest little humidifier may not have the sleek looks or digital read-outs of other air purifiers on this list, but the Holmes HAP9726B is no joke. In our smell test, it was able to noticeably diminish the fish oil smell, but struggled more with cinnamon. One downside to the Holmes is that some of its fan speeds are pretty loud; that might deter users from actually activating the higher settings, which is a shame, since it seems to be able to move a lot of air quickly, and that may improve the air quality at a faster rate.

The Holmes has a very basic, intuitive control panel. It comes with a handle that makes for easy moving.

This all-in-one air purifier and humidifier has over 20 different symbols that live on the control panel, ranging from the amount of particulates, filter and water bucket statuses, troubleshooting hints, odor and dust warnings, and more. While helpful, testers found that these symbols can be confusing and hard to understand.

加湿器有紫外线水处理等to kill bacteria in the water bucket, which makes sense because in addition to using either the air purifier or the humidifier singly, you can also select the Humid Purify mode, which uses the humidifier in conjunction with the air purifier to help cleanse your air. The LG Signature is also compatible with LG's ThinQ app, so it can be controlled remotely from your smartphone.

The LG did the best job of all tackling cigarette smoke. It did equally well when it came to cinnamon, so if you don't want fragrance smells hanging around, this air purifier can help you out.
