## 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.)

**Molekule Air Pro** — Three hands-on testers bench-tested the Molekule Air Pro — Tom's Guide (July 2025), Reviewed/USA Today (Feb 2024) and TechRadar (Sept 2024) — and agree it filters effectively, surfaces detailed multi-pollutant air-quality data on its screen and companion app, and looks premium, but is loud at high fan speeds and very expensive with costly proprietary filters. All three measured high-speed noise (65-78 dB) and confirm the ~$1,000+ price plus roughly $175 twice-yearly filters. FDA Class II medical clearance is confirmed by Reviewed and TechRadar. (3 sourced reviews.)
