Why it matters
The Coway Airmega 150 is a HEPA room unit air purifier that its maker rates for 214 sq ft.
At the usual 4.8 air changes an hour and an 8-foot ceiling, a 214-square-foot rating implies about 137 cubic feet of clean air a minute. In a 12-by-15-foot bedroom that would turn the air over roughly 6 times an hour.
Filtration: HEPA. Quietest setting, per the maker: 19.98 dB. Power draw: 35 W.
Price-wise it sat in the middle third of the 74 hepa room unit models we cover when we checked; the button shows today's price.
