## What reviewers say

**Coway AP-1512HH Mighty** — HouseFresh's chamber test rates the Coway AP-1512HH Mighty a strong cleaner — clearing incense smoke in a 728 cu ft lab in 26 minutes at top speed with a 247.7 CFM dust CADR — but flags it as unusually power-hungry (75.3W) and now dated, with better-value rivals available. (1 sourced review.)

**Winix 5520** — Only one whitelisted tester (Wirecutter) hands-on tested the exact Winix 5520, and only in its dismissed-competition section: a capable purifier that tested worse and louder than Coway's Mighty 2, with a dark, monolithic form that stands out in most rooms, a display that shuts off only on the lowest and least effective fan speed, and an ionizer that reactivates on every power-on. No lab numbers were published for this model. (1 sourced review.)
