## 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.)

**Dyson Purifier Big+Quiet Formaldehyde BP04** — Three whitelisted outlets (TechRadar, Reviewed/USA Today, TechHive) hands-on or lab tested the Dyson Purifier Big+Quiet Formaldehyde; TechRadar and Reviewed covered the higher CO2-sensor trim (aligned with BP04) while TechHive tested the base Formaldehyde unit. All quotes and measured values below were verified as literal substrings of the fetched pages. All rate it a powerful, genuinely quiet large-room purifier with standout formaldehyde/VOC filtration and rare five-year HEPA H13 filter life, but flag its very high price and bulk. Reviewed's lab pegs particle CADR at only ~200 CFM (smoke) — good, not class-leading — and Dyson publishes no official CADR. (3 sourced reviews.)
