## What reviewers say

**Blueair Blue Pure 211i Max** — Only one whitelisted tester, Wirecutter, published hands-on measured results for this exact model, naming it their large-room upgrade pick. Wirecutter found it a stellar, quiet, energy-efficient large-room performer (>99.9% smoke reduction), with a durability caveat on the washable fabric cover. (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.)
