## 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.)

**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.)
