Why it matters
The Winix C545 Air Purifier is a compact / desktop air purifier that its maker rates for 360 square feet.
At the usual 4.8 air changes an hour and an 8-foot ceiling, a 360-square-foot rating implies about 230 cubic feet of clean air a minute. In a 12-by-15-foot bedroom that would turn the air over roughly 10 times an hour.
Filtration: Pre-Filter. Quietest setting, per the listing: 27 db.
Price-wise it sat in the dearest third of the 30 compact / desktop models we cover when we checked; the button shows today's price.
