This Coway Mighty 2 review finds the Airmega Mighty2 is the fastest quiet purifier in its class. It cleared PM1 particles from a 728 cu ft test room in 23 minutes at top speed, faster than the Levoit Vital 200S and Winix 5510, according to HouseFresh, an independent site that bought the unit and tests purifiers in its own lab.
HouseFresh also measured three fan speeds under 45 dB, a first for Coway. The trade-off is cost: it estimated $145.94 a year to run the Mighty2 24/7 at full speed, and there is no app.
It listed at $269.99 on Amazon on Oct 16, 2026, with a 4.6 rating. Wirecutter now names it its top pick.

My Planned Test
Planned test: I plan to compare the Mighty2 against my current purifier in the same room, timing how long each takes to clear smoke on a quiet speed. I will add my results and my Home Smart video here when they are done. Until then, nothing on this page is a hands-on claim from me.
What YouTube Reviewers Found With the Mighty2
These findings are paraphrased from the video transcripts and credited to each creator. They are the creators’ own test results and opinions, not mine.
- HouseFresh (bought a Mighty2 with its own money): at top speed it took 23 minutes to clear PM1 particles from its 728 cu ft test room, faster than the original Mighty, the Vital 200S and the Winix 5510. It estimated a PM1 CADR of 260 CFM and measured 56.9 dB on turbo.
- HouseFresh: three of the Mighty2’s fan speeds stayed under 45 dB, a first for Coway. At speed 2 (42.6 dB) it cleaned the room in 38 minutes, 8 minutes quicker than the next traditional purifier in its comparison.
- HouseFresh praised the slide-out pre-filter, which it suggests vacuuming every 2 to 4 weeks, especially with pets.
- HouseFresh: the Max2 filter costs $69.99 and Coway says to replace it every 12 months. At 49.12 W on top speed, HouseFresh estimated $145.94 a year to run it 24/7 at full speed. There is no app, but it works with a smart plug, and Coway offers a 3-year warranty.
- The YouTube channel Project Farm (buys every product it tests): the Winix 5510 (about $180) came out on top overall. In a 30-minute smoke test it removed 3.9 million particles, versus 3.52 million for the original Coway Mighty (about $229) and 3.18 million for a Dyson (about $1,200). Its one downside was noise, about 63.1 dB on high.
