Our take
This is the air purifier to get if you want to stop thinking about it. Reddit has been recommending the Coway Mighty for years and nothing has knocked it off the top spot — that kind of sustained community consensus is hard to argue with.
Winix is the brand Reddit's frugal and air quality communities keep coming back to, and the 5500-2 is the model that shows up most. It's not flashy, but it cleans air efficiently, runs quietly, and replacement filters won't break the bank.
