Coway Airmega Mighty2
Air purifiers — mid-size mechanical HEPA, Wirecutter top pick · Reviewed by Katie · amazon.com live, Sept 9 2026
Why it scored a 82
At $269.99 the Coway Airmega Mighty2 is the 2026 successor to the AP-1512HH Mighty and already Wirecutter's top pick and HouseFresh's overall best. Quality leads at 90 and Reliability at 94: the ionizer is gone, the pre-filter slides out the front for washing, a laser sensor reads PM1 through PM10, and the filter lasts 12 months with a 3-year warranty. Value sits at 74 and Features at 62 because there is no app or Wi-Fi and the first-year cost of roughly $415 is the highest in the mid-size tier. It is for a buyer who wants the best-tested mechanical HEPA purifier and does not care about smart-home control.
