## What reviewers say

**Coway AP-1512HH Mighty** — HouseFresh's chamber test rates the Coway AP-1512HH Mighty a strong cleaner — clearing incense smoke in a 728 cu ft lab in 26 minutes at top speed with a 247.7 CFM dust CADR — but flags it as unusually power-hungry (75.3W) and now dated, with better-value rivals available. (1 sourced review.)

**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.)
