The best air purifier for a bedroom: Coway AP-1512HH and Airmega 150

Why use an air purifier in the bedroom?

Science already tells us that we sleep better in purer air. In fact, some of your sleep trouble may be caused by air pollution. All of that is to say, adding a purifier to your bedroom could be a serious game-changer, and allow you to get some much-needed REM sleep, uninterrupted by pollutants in your air.


What makes the perfect air purifier for a bedroom?

For sleeping, you want less noise, and a low setting or Auto Mode that lets you dream without having to adjust the fan yourself. Combining all of that with advanced, effective purification with HEPA technology, you’re in for the kind of clean air that will let you stay in dreamland as long as your body needs. Finally, you’ll want to find a smaller purifier to fit in your bedroom, and match your aesthetic. Meeting and exceeding all these standards are the Coway AP-1512HH/AP-1512HHS (already awarded “Top Pick” for air purifiers 5 years in a row by Wirecutter Magazine ) and the latest purifier on the scene: the Coway Airmega 150.


Effective Purification     

HEPA technology is the highest standard for air purification in the world. The Airmega 150  uses a combination of a pre-filter, deodorization filter, and Coway Green True HEPA™ Filter, which efficiently filters harmful sources in your space and removes more than 99.999%* of nano-sized particles down to 0.01 microns—smaller than most viruses and bacteria. The tiny 18-inch purifier uses this technology with an impressive 214 square feet of effective coverage. The slightly larger AP-1512HH/AP-1512HHS has the same effectiveness in rooms up to 361 square feet.


Less Noise

Coway’s advanced filtration technology is designed to be as quiet as possible—perfect for a nursery, bedroom, or any room where sleeping takes place. On low, the Airmega 150 emits a noise level of only 19.98 db—you can barely notice the sound that is produced by the fan, although it’s still circulating the entirety of air in your room.


Auto Mode

Both the Airmega 150 and AP-1512HH feature an auto-mode that keeps the purifier on only when needed, so you don’t have to turn the fan on or off yourself. If you’d rather have one fan speed on through the night, there is a low setting for that, as well. Upgrade to the AP-1512HHS with enabled wifi, and you can even change the unit’s settings from your bed with the smartphone app. 


LED Lights that can turn off

If you want complete darkness in your room, the Airmega 150’s LED indicator lights will turn on and off by your preference.

So, it comes down to room size, aesthetic and personal preference

For larger bedrooms, the AP-1512HH gives powerful purification up to 361 square feet with a nice quiet fan, and auto mode. For a smaller space, or those who prefer the lights off function, the 18.5” tall Airmega 150 gives coverage up to a 214-square-foot bedroom. Both purifiers are designed with modern, sleek lines to match the aesthetic of any bedroom.
