In a separate, similar test, we fed the purifiers continuously smoky air by burning incense sticks throughout the test. This test also included the Coway AP-1512HH Mighty, compared against a former large-space pick, the Blueair Blue Pure 211+. In that test, we learned we had to run the machines on high to maintain meaningful purification. Both models achieved this, cutting the particulates by half or more in 50 minutes. Most air purifiers arrive with the filters installed—but they are also sealed in plastic wrappers. Open up your machine, unwrap the filters, and reinstall them.

We have also removed from this list many since-discontinued models we tested. Some units had fan issues (but they seem to be resolved). In early fall 2020, a few reader comments and reviews showed up mentioning an imbalanced fan in the machine, which caused the whole unit to shake uncontrollably and, in some cases, led the fan to break.
AutoDetect for intelligent air quality monitoring and self-adjusting fan speed. To test air purifiers, I light an incense stick in a 200-square-foot room, burn it for 15 minutes, and then turn the purifier on and run it on high for two hours. I take particulate matter (PM) and VOC measurements every 15 minutes to see how well and quickly the unit removes the irritants.

The Coway Airmega 250 is the larger, more powerful sibling of the Coway Airmega 150. It’s equally attractive, but it’s only slightly more powerful than our top pick, the honeywell humidifier Coway Airmega AP-1512HH Mighty, yet it costs $200 more. Finally, because the 211i Max is likely to be used in a living room or other public space, it’s gratifying that Blueair put some real care into its appearance and upkeep. The tweed-like cover (which also acts as a prefilter) is washable and, when the time comes, replaceable.
If you’re supplying an alternate User-Agent string,try changing back to default as that can sometimes result in a block. This unit is lightweight, portable, and does the job well.
Both the built-in control screen and the app show the real-time levels of airborne particulates in three size classes (1, 2.5, and 10 microns, roughly corresponding to smoke, dust, and pollen). This is standard info in an air quality monitor, but it’s something we’ve rarely seen integrated into a purifier. The app also lets you remotely monitor and adjust the operating settings. We’ve tested more than 60 air purifiers in the past nine years, and the exceptional Coway Airmega AP-1512HH Mighty is our top pick among them. It’s powerful enough to clean a large room, quiet enough to sleep near, engineered to run for years, and inexpensive enough to set up several throughout a home. But it’s not the only excellent air purifier we’ve found, and if you prefer the looks, price, or features of our other recommendations, be assured that they, too, are top-notch performers.
