Dust, dirt, and germs are a fact of life. Even the best air purifiers can't purge your home of every contaminant − but they can detect and destroy pollutants, circulate fresh air, and improve your quality of life.  

There are cute and compact air purifiers that would fit right into a nursery, as well as bigger, broader machines that can cleanse larger spaces. Antibacterial purifiers work to kill germs, while antiodor models target pet smells and shed hairs. 

Everybody deserves to breathe clean air, but not everybody does, especially those of us who live in urban areas. That's why it's so important to pick the right air purifier. As a shopping writer and a smart tech enthusiast, I know what to look for in an air purifier. I've spent hours searching the specialist sites to bring you the very best. 

We're constantly testing to make sure that we bring you all the best products. That's why almost every air purifier in this guide has been reviewed by one of our experts. When we haven't been able to get our hands on a machine, we've scoured the specifications and read countless customer reviews. We've ranked these air purifiers based on coverage, filtration, design, and the all-important price.

Best air purifier

1. Mila Air Purifier

Best air purifier for air quality monitoring


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

Reasons to buy

Offers comprehensive air quality information
Customizable filters
Connected to app

Reasons to avoid

Large and a little awkward to place
Buy it if:

You're on a budget:  Mila is pretty affordable for a premium product.
You have specialist needs: this machine comes with custom filters to suit everybody from pet-owners to new parents.
You live in a studio apartment: one Mila can cleanse all the air in a space up to 1000 sq. ft. 

Don't buy it if:

❌ You're easily overwhelmed: Mila's regular air quality updates might feel like too much information.
You don't like hidden costs: you'll need to replace the filters every six months, and they don't come cheap. ❌ You're super-sensitive to noise: on its highest setting, Mila is one of the loudest air purifiers on the market. With that said, this machine incorporates room-sensing technology to go quiet when you come in.

The bottom line

🔎 Mila Air Purifier is the best air purifier on the market, hands down. This machine is super-smart, with a filter to suit every need. 

This air purifier is designed by three dads, living amongst the smog of Shanghai, who wanted cleaner air for their kids. When they couldn't find a machine that met their needs, they made their own: the Mila Air Purifier.

You can measure and adjust the quality of your air inside the Mila app. Once you set the fan speed on a sliding scale of 1% to 100%, the machine will take care of the rest.

Mila also monitors for mold growths and carbon monoxide leaks to prevent accidental poisoning. The app explains it all in clear language, using words (and emojis) you can understand. 

This machine comes with custom filters to suit specialist needs. Whether you're an animal-lover who's looking to rid your air of pet smells and shed hairs, or a new parent who wants to protect your child's delicate immune system, Mila's got a filter for you. 

It can be a little overwhelming to have so much information at your fingertips. If you suffer from health anxiety, you might want to shop elsewhere, or at least minimize your Mila screen time. 

This fan has something for everyone. And, as smart tech goes, the Mila Air Purifier is pretty affordable. It's cute and compact to boot, so it will look just as good in your child's nursery as in your family room.

Filter: HEPA
Dimensions: 36.33 x 12.29 x 11.02"
Weight: 18 lbs

Reasons to avoid

No heating option
Buy it if:

You want a multifunctional machine: this air purifier doubles as a fan and a humidifier. It's great if you live in dry, arid areas.
You like your machine to do the work: the Dyson purifier provides detailed feedback on your air quality, and even draws little graphs for more visual learners.  
You suffer from allergies: the Dyson has HEPA filters which claim to capture 99.97% of allergens. 

Don't buy it if:

You're short on space: this machine is a foot wide, a foot deep, and three feet tall. You might struggle to store it in smaller rooms.
You want an air purifier that doubles as a heater: this machine is an air purifier, a humidifier, and a fan only. ❌ You're on a budget: at $1000, this is one of the more expensive air purifiers on the market. 

The bottom line

🔎 With the Dyson Purifier Humidify + Cool fan, you get three functions in one machine. Your air won't just be purer, but cooler and moister, too. 

An air purifier is what I like to call a home comfort appliance. It might not be necessary, but it's nice to have. Cooling fans and humidifiers fall under the same category. 

Purchasing each of your home comforts individually can cost you hundreds, if not thousands, of dollars. With the Dyson Purifier Humidify + Cool Formaldehyde fan, you get three functions in one machine, for $1000. Not too bad, when you think about it. 

Since this fan is remotely operated, you can use it from anywhere in the house. Once you've downloaded the app and filled the humidity reservoir, you won't need to touch it again. 

You don't need to understand environmental science to use this fan. The in-app air quality reports are written in plain English and translated into simple graphs for more visual learners. 

The Dyson impressed on test, particularly as a humidifier. This machine cleans itself, using UV light to kill any bacteria in the reservoir. 

The only real downside is the size. Three feet tall and one foot wide, the Dyson is on the larger side. You can't hide it, and you might struggle to store it in smaller spaces.
