How To Check Your Air Quality
A Note on Air Quality Monitors
Many large states and cities are required to report the local outdoor
, which was established by the Environmental Protection Agency and measures the concentrations of major air pollutants, like ground ozone and carbon monoxide, that are regulated by the Clean Air Act. My favorite app for keeping track of the local AQI is Wynd’s
. To check if your indoor air quality stacks up, consumer AQ monitors like
also measure carbon dioxide, temperature, and humidity in addition to pollutants and particulate matter. All the purifiers I tested measurably reduced particulate matter, but I was unable to test them against wildfire smoke or pollution (thankfully).

Our Top Pick
Coway Airmega 200M
For sheer simplicity and affordability, the Airmega 200M will probably fit most peoples’ lives, houses, and budgets. The compact, attractive device easily fits in a corner of my bedroom and is effective for spaces of up to 361 square feet. It saves energy with an included air quality monitor that turns it off when no pollution is detected, and automatically increases the fan speed if it detects particles. When my dog plopped down in her dog bed, or even when I cooked bacon with the bedroom door open, the Airmega 200M roared to life. You’ll want to turn off the AQ monitor’s light at night, though.
Pure Hot Cool Link
The smaller version of the
uses Dyson’s bladeless fan technology to circulate air around your room efficiently and a double-layered HEPA and graphite filter to weed out both volatile organic compounds and noxious odors. It may seem expensive, but it also doubles as a heater during the colder months and can provide focused, or more diffuse, streams of hot or cold air. If you’re not interested in checking the app, there’s also
that isn’t Wi-Fi-enabled.
Best for Travel
About the size of a water bottle, the Wynd Plus is one of the smallest air purifiers on the market. It’s not a HEPA filter, but it can clean all particles greater than 0.3 microns, which includes auto emissions and most wood smoke, in about a 3-foot span. It also comes with its own air quality sensor, a microfiber traveling bag, and a small kickstand to prop it upright. I brought it on vacation with my family when statewide wildfires threatened to halt our summer vacation and set it on the nightstand next to my two young kids to keep their lungs from getting irritated.
For Persistent Coughers
Molekule Air Purifier
Instead of filtering out pollutants and particles, the Molekule destroys them. It uses a pre-filter and a patented technology called photo-electrochemical oxidation (PECO) to purportedly break down pollutants as small as 0.1 nanometers (most HEPA filters only filter out pollutants that are 250-300 nanometers wide). It’s hard to measure how effective PECO is, since most AQ sensors can’t detect pollutants that small. Also, unlike other air purifiers, the Molekule doesn’t come with a built-in sensor. But if you’ve tried other air purifiers and had no results, this one is worth a shot. It’s very quiet, slim, and attractive. Anecdotally, I did notice a difference in sneeziness when stepping out of my Molekule-d bedroom and into my dog-haired living room.
My Personal Fave
Blueair Classic 480i
Founded over two decades ago in Sweden by an Electrolux alum, Blueair makes some of the most reliable air filters on the market (disclosure: I own
). The Classic 480i can purify rooms of up to 484 square feet. It’s Wi-Fi-enabled, and you can check its built-in air quality sensor on the Blueair Friend app. It’s so quiet that I had to check the app to see if it was turned on, and it uses about as much power as a lightbulb. However, it’s expensive, awkward to position, and bulky. Blueair offers
for rooms of different sizes.
