Our take
Coway sells the 200M through different shops from the Mighty, but inside they match: the same filter set, motor, sensor and controls. Reviewers at Wirecutter and RTINGS found the front grille is the only real difference.
That makes the choice easy. Its smoke CADR of 233 cfm suits rooms of about 34 m², and whichever of the two is cheaper on the day is the one to buy.

Questions about the Airmega 200M
- What size room does the Coway Airmega 200M cover?
- About 361 ft² (34 m²). That's AHAM's room size for its smoke CADR of 233 cfm: the floor area, with an 8 ft ceiling, whose air it cleans about every 12.5 minutes.
- Is the Coway Airmega 200M enough for smog?
- For smoke and heavy smog AHAM suggests a smoke CADR at least equal to the floor area in square feet. By that measure the Coway Airmega 200M keeps up with a room of about 233 ft² (22 m²). Keep the windows shut and run it on high while the AQI is bad.
- Is the Coway Airmega 200M the same as the AP-1512HH?
- Nearly. Wirecutter and RTINGS both describe the same filters, motor and controls; the front grille is the visible difference, and the filters are interchangeable.
How we judge. We haven't tested the Airmega 200M in a lab of our own. The figures come from independent ratings (AHAM, Energy Star, NIOSH, the ASPCA) or the maker, and the verdict is ours, from those figures. No brand pays to be listed. Last checked Nov 7, 2026.
