## 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.)

**Alen BreatheSmart 75i** — Two whitelisted hands-on reviews (TechHive 2023, TechRadar 2024) cover this exact model. Both are qualitative with no lab-measured numbers. Both praise the powerful airflow for very large rooms (up to ~1,300 sq ft), the swappable colored front panels, and simple onboard controls that work without the app. Both flag the high price, being overkill for small spaces, loud higher/auto fan speeds, bulk, and an app that is hard to find or unintuitive. They split sharply on setup and framing. (2 sourced reviews.)
