Coway Airmega Mighty2 review
$250–300Research-based· Last verified 2026-10-27
Verdict
The 2026 successor to Coway's long-running Mighty. HouseFresh measured the most cleaning at quiet fan speeds of the mainstream purifiers here, and its CARB certification is on the state's public list. It's the widest unit in this guide and has no app.
Best for: Studios where you sleep a few feet from the purifier · Buyers who want set-and-forget with no app or ionizer
Trust Score: 84/100 (Good)
Confidence: Low (2 independent sources)

| Pillar | Score |
|---|---|
| Independent evidence | 25/30 |
| Safety & compliance | 16/20 |
| Specs & claims transparency | 16/20 |
| Brand accountability | 15/15 |
| Warranty & support | 12/15 |
Why this score: Two independent hands-on reviews agree it cleans well and quietly, and HouseFresh's measured CADR matches Coway's rating. Its CARB certification is on the state's public list, and Coway publishes full dimensions, a US contact and warranty terms. It loses points for having only two sources and no declared materials, and we count the 1-year whole-unit warranty, not the longer motor coverage.
Not hands-on tested. This score is based on public, verifiable evidence. Commissions never change a score.
