Pollution, dust, pet dander, allergens, and germs are an unfortunate part of everyday life. However, bringing one of the best air purifiers into your space means you can reduce the number of unwanted pollutants and improve your quality of life.

Air purifiers work by filtering the air in a space using an internal fan that sucks in surrounding air, then pushes it through several layers of filtration, dispersing clean air into your environment. Air purifiers can reduce and even eliminate unwanted irritants and particles like dust, pet hair, and smoke. 

Some can go as far as working to remove odors and even viruses. Air purifiers improve the overall air quality in your home, making them vital for allergy sufferers, and people with asthma or other respiratory issues.

To help you to choose the best air purifier, we've tested the leading products. Whether you're looking for a stylish purifier that will blend in with your carefully chosen décor, or a machine quiet enough for the bedroom, we've found an option for your needs. While not all air purifiers are created equal, the general consensus from experts is that the use of an air purifier is worthwhile, and adds immense health benefits to your home.

1. Mila Air Purifier

Best air purifier for air quality monitoring

Specifications

Coverage: Up to 1000 sqft
Filter: HEPA
Dimensions: 18.5 x 14.7 x 14.7in
Weight: 17.9lbs

Reasons to buy

+
Detailed and comprehensive air quality information
+
Attractive, modern design
+
Easy-to-use app
+
Personalize filters based on needs

Reasons to avoid

-
Large and a little awkward to place
-
The amount of information may overwhelm beginners

Mila's Smart Air Purifier is packed with more features than you could wish for and packaged in a modern, Scandi-style rectangular unit, it works as hard at informing you about the quality of your indoor air as it does cleaning it. The app is the star of the show, with gorgeous graphics that make cleaning the air a fun activity rather than a chore. Settings also allow you to change performance depending on whether you live in an old or new building.

Mila also offers customizable options based on your needs. While it has an all-in-one general filter (H12 HEPA), you can also upgrade with filters designed for pet owners, nurseries, mothers-to-be, general allergies, home renovations, or someone who wants the ultimate in protection, with 'The Over-reactor' featuring H14 HEPA + Formaldeyhyde-targeted carbon. It's pretty big, but its wooden legs and white casing mean it will look smart and stylish in most spaces. 

The only criticism we had is how overwhelming the purifier can be over time, picking up the smallest change in air quality and making it seem at times like you're waging war against pollutants. That could be a positive for many people, however, and in no way diminishes how impressive it is.

2. Dyson Purifier Hot+Cool HP07

Best multifuncational air purifier

Specifications

Coverage: 800 sq ft
Filter: HEPA
Dimensions: 30.1 x 9.7 x 9.7in
Weight: 12.4lbs

Reasons to buy

+
Timers and smart home compatibility
+
Also works as a heater and fan
+
Good air quality data on app
+
10 speeds settings

Reasons to avoid

-
Not as quiet as some
-
Doesn't purify as quickly as other designs

Dyson's Purifier Hot+Cool HP07 works to clear dust and pollutants from your home. It has the added functionality of keeping you warm, or cool, so it's useful all year long. The purifier is fantastic if you already have a smart home, allowing you to control it with Alexa voice commands, and you can use the app and remote control provided to set the fan speed, switch to night mode, set timers and so much more. 

The small display on the front shows you in-the-moment data about any nasties in the air, or you can really dig into the numbers via the app. 

The only potential drawback is that we've read a handful reviews that mention a low whining or whistling noise over time.

Molekule air proH&G silver badge

Best air purifier for large spaces

Specifications

Coverage: Up to 1,000 sq.ft.
Filter: PECO
Dimensions: 23.1"(H) x 10.9"
Weight: 22.9lb

Reasons to buy

+
Attractive look
+
Easy set-up
+
Identifies your space's top offenders in your air and reacts automatically
+
Patented PECO tech not only traps but destroys pollutants
+
Quiet

Reasons to avoid

-
Filters are expensive to replace and seem to go through life span quickly
-
Blue UV light could disrupt light-sensitive sleepers if placed in a bedroom

Molekule is everything you could want in an air purifier: its sleek design fits nicely into your decor, quickly jumps into action with any changes in the air, and offers detailed insight into your air including VOCs, particle counts, carbon dioxide, and humidity. On test in an open floor plan area that encompasses a kitchen, breakfast room, and living room, it's so quiet that we almost forgot it was there. 

 The Air Pro has a 360-degree air intake design at the bottom of the machine, where the air flows through outer filter layers to trap larger particles and slow down chemicals. It goes through a PECO filter, where it goes through an oxidation process activated by LEDs. The cycle is completed in the form of the purified air dispersed from the top in a 360-degree motion as well. If you don’t need something that can fit rooms up to 1,000 sq. ft., I imagine you’ll get on just fine with the Mini for spaces up to 250 sq. ft.

However, replacement filters are pretty expensive and last about six months. Though, if you participate in the auto-ship when filter life gets low, it’ll auto-ship a new filter for $99, as opposed to $160.  It automatically stops working when the filter is beyond the recommended usage, and it can identify and reject any third-party filters. The blue UV light that emits from the machine could disrupt light-sensitive sleepers if placed in a bedroom.

Best air purifier for value

Specifications

Coverage: Up to 1358 sq.ft.
Filter: HEPA
Dimensions: 9.84" x 15.2"
Weight: 7.27 lb.

Reasons to buy

+
Color-coded air monitoring system
+
2-, 4-, and 8-hour timer settings
+
Auto, Turbo, and Sleep modes
+
Child lock capabilities
+
Purifies a 120 sq. ft. room in 5 minutes
+

+
99.99% removal rate of H1N1, E. Coli, Salmonella, S. aureus, and Candida albicans

Reasons to avoid

-
No app-connectivity
-
Would love to see a handle

The Dreo Macro Pro can remove pet dander, pollen, and VOCs quickly (up to five air changes in an hour) and has a 99.99% removal rate of H1N1, E. Coli, Salmonella, S. aureus, and Candida albicans with a three-stage HEPA filtration system and 360-degree design. It has three-speed settings and Turbo mode and quiet sleep mode though the convenient Auto feature means that the machine can automatically adjust according to what is detected in the air.  Our tester Alex Temblador used this small, yet mighty device in a dusty, 100-year-old house and remarked on the improvement in her home’s air quality. 

It can cover rooms large and small, though more air changes more frequently in smaller spaces. It can sit on the floor or a tabletop, though some sort of handle would be nice. It doesn’t have any app connectivity or smart features per se, but lets you easily monitor current air changes with a color indicator.

Samsung bespoke cube air purifierH&G silver badge

Best smart air purifier

Specifications

Coverage: Up to 350 sq.ft.
Filter: HEPA
Dimensions: 9.84" x 15.2"
Weight: 27lb.

Reasons to buy

+
Gorgeous, modern design
+
Several settings, including a wind-free and pet function
+
Works with Samsung Smart Things App
+
Some filters are washable

Reasons to avoid

-
Only covers spaces up to 350 sq. ft.
-
Requires continuous bi-monthly maintenance

My first impressions of the Samsung BESPOKE Cube revolved around its stylish geometric design, but what left me most excited was its smart and unique features: like a pet mode, wind-free mode, and tons of data insight on the Smart Things App.

It’s also quite nifty for pet owners, with a 5-layer filtration system that keeps pet odors and hair in mind with the design. You can also simply let the BESPOKE do its thing - if you run it on SMART mode, it will adapts to the environment in real-time and senses impurities by constantly analyzing the indoor air quality.

It has a pretty elevated price point and works best in smaller spaces up to 350 sq. feet. For this reason, we think it’s best purchased on sale. It’s best suited for a bedroom, office, or living room as opposed to an open floor plan style space. 

Unlike other machines, Samsung recommends checking and rinsing the reusable pet filter every two weeks, meaning more upkeep than other machines.

6. Levoit Core 300 True HEPA Air Purifier

Best air purifier under $100

Specifications

Coverage: Up to 430 sqft
Filter: HEPA, Carbon
Dimensions: 14.1 x 8.6in
Weight: 9.2lbs

Reasons to buy

+
Quiet on lowest settings
+
Low power consumption
+
Timer
+
Sleep mode

Reasons to avoid

-
May not perform well in larger spaces

The lowest-cost option on our list, the Levoit Core 300 is a great option for those who are conscious about how much power a traditional air purifier may consume.

The Core 300 allows you to have more control over how you use it, with four different timer settings. With 2H, 4H, 6H, and 8H options, you can choose how long you want the machine to run without needing to physically switch it off. Ideal for putting in the kitchen to eliminate food odors after cooking.

Small and compact with a nice design, it’s also capable of being tucked away in any room without sticking out too much and is light enough to be moved from room to room if you desire.

The Levoit Core 300 doesn't have the bells and whistles of other machines in this guide, like smart settings or detailed information about your air, but it does come at one of the most lowest price points. Its small design makes it useful for tabletop placement, and it's best suited for smaller spaces, like bedrooms and home offices.

Best air purifier for viruses

Dimensions: 18.5 x 11.2in
Weight: 15.4lbs

Reasons to buy

+
Attractive look

Combat against coronavirus

Reasons to avoid

-
Noisy on higher fan settings
-
Mobile App could be improved
-
Filters are expensive to replace and have volatile availability

Using technology developed at MIT and designed and made in Switzerland, the Aeris Aair Lite is an advanced air purifier that, according to outside tests coordinated by the company, is able to filter and kill around 94% of the respiratory droplets that spread Covid-19. 

Now it's important to understand that no air purifier will eliminate the risk of viruses, but it can provide a little peace of mind. The Aair Lite uses antibacterial and antimicrobial filters on its mesh (and interchangeable) cover alongside its HEPA filter to go the extra mile for the health-conscious.

While the top two speed levels (of five) were a little noisy, the purifier was whisper-quiet on lower settings and perfect for the bedroom or any small space around the home. We used this air purifier for over a year, and while we enjoyed it, there were lots of inventory shortages when trying to order replacement filters. Since we've tested, the company has been acquired by iRobot.

Best air purifier with a fan

Dimensions: 19.1 x 16.5 x 14.5in
Weight: 16.2lbs

Choice of colors

Reasons to avoid

-
Large

Can be quite noisy when on higher settings

Dyson may be the most famous brand for combining cooling and air purifying into one device, but Blueair has its own offering in the form of the Blueair Blue Pure Fan. Primarily working as a fan with a HEPA filter built-in, it allows you to be sure that the air you're breathing is as clean as possible.

The design is lovely, Scandi-inspired with wood-effect legs and a leather handle on top, and the rear benefits from changeable pre-filters in a choice of colors including blue, pink, and yellow.

Despite not having an oscillation feature, airflow is put out across 90 degrees because of the design of the face.
