A lot of the conversations surrounding air pollution revolves around the outdoors, but given that the average person spends 93 percent of their lives indoors, the quality of the air inside is just as, if not more so, important. In fact, the air inside can be five-times more polluted than the air outside thanks to the lack of circulation in a lot of indoor spaces.


1.Coway Airmega 200M

For sheer simplicity and affordability, the Airmega 200M will probably fit most people’s lives, houses, and budgets. The compact, attractive device easily fits into a corner of my bedroom and is effective for spaces up to 361 square feet. It saves energy with an included air-quality monitor that turns the machine off when no pollution is detected and automatically increases the fan speed if it detects particles.

When my dog plopped down in her bed, or when I cooked bacon with the bedroom door open, the Airmega 200M roared to life. You’ll probably want to turn off the AQ monitor’s bright light at night, though.

Pros & Cons

2.Dyson Pure Hot +

Filtering out volatile organic compounds and particulates is one way of making the air in your home safer. Adjusting it to the correct humidity is another important component, and it’s often ignored. Indoor air is usually very dry, and viruses love dry air. Having the right indoor humidity inactivates viruses much faster than normal, making airborne viruses less likely to infect you.

That’s why I really like Dyson’s purifier (9/10, WIRED Recommends), which I tested last spring. Its almost entirely automated self-cleaning mode takes care of the worst aspect of humidifiers—keeping them mold-free.

Pros & Cons

3.Blueair Pure Fan Auto

The Pure Fan Auto looks more like a little piece of art than an air purifier. We like other Blueair products, and this one adds cool air to its purifying capabilities—it cycles air five times an hour in a 326-square-foot room. The fan is not powerful enough to cool down a super hot room on its own, but it feels quite nice if you’re sitting in front of it.

It hardly makes a sound, but if you’re a light sleeper, Night Mode turns the fan to its lowest setting and shuts off the air quality indicator light. The standard Pure Fan costs the same as the Auto, but the latter offers auto mode, night mode, plus an air quality indicator light.

Most Honorable Mentions in the post


I’ve had this air purifier for over a year now; I originally purchased it to help with my seasonal allergy symptoms flaring up, but have found it to be effective no matter what season it is. This is a compact, yet effective, HEPA air purifier that is also easy to use.

Featuring 360° deep purification, this air purifier has three different modes, including a quiet setting that won’t disturb your sleep if you’d like to keep it running. I keep mine in my bedroom (which is where I also work during the day) on my nightstand; it’s so quiet, I can leave it on throughout the day while I’m on Zoom calls or composing emails without any distracting sounds.

Pros & Cons

5.Pure Enrichment PureZone

This air purifier is compact enough to take with you on the go, or keep on a small or cramped desk without eating up precious space. But don’t let its small size fool you — it doesn’t sacrifice efficiency for size. Featuring a two-stage air purification process, this purifier promises to eliminate up to 99.7 percent of contaminants, whether that be pollen, dust or foul odors.

It’s also quiet enough to efficiently clean the air without drawing attention to itself, whether you happen to be using it on public transport, a study session or you just generally prefer to see, not hear, your air purifiers. The filter should be replaced every six months and is very inexpensive.

Pros & Cons

6.Holmes Desktop

You’d be forgiven if you gave this a quick glance and mistook it for a clock or radio, but this air purifier’s slim design makes it suited perfectly for desks and other workspaces, whether you need it to sit horizontally or vertically to accommodate laptops or other belongings.

Mold, smoke, bacteria, pet dander and other contaminants are no match for the powerful HEPA filter and ionizer duo, working in tandem to keep the air from being dirty and stale.

Pros & Cons

7.Molekule – Air Mini+

This mini air purifier by Molekule may be significantly more expensive than the others mentioned on our list, but that’s because it’s more powerful. By using a process known as Photochemical Electrochemical Oxidation (PECO) nanotechnology to destroy contaminants in the air. In short, instead of trapping things like dust, mold and viruses, this air purifier actually destroys them.

But don’t worry, you don’t have to be Bill Nye the Science Guy to use this; in fact, this air purifier’s settings are extremely customizable. Though there are five pre-set speeds available, and you can automate settings to be even quieter or more powerful to match to your unique preferences.

Pros & Cons


Best Compact Air Purifier – If left unchecked, a lot of the pollutants hiding in the air can have damaging effects on our health, from agitating those who suffer from allergies or asthma to provoking respiratory infections.
