## What reviewers say

**Levoit Core 300S** — Two whitelisted hands-on testers reviewed this exact model: TechRadar (2023) and Tom's Guide (2025). Both measured it as genuinely quiet (60dB max at high speed) and praised its compact, low-cost, easy-to-set-up design. Both flagged sluggish, sometimes absent sensor response to sudden air-quality changes, making it better for steady background use than reactive cleanup. (2 sourced reviews.)

**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.)
