Coway Airmega Mighty2 Air Purifier Review

The Coway Airmega Mighty2, launched at the end of March, is an upgraded version of the popular Mighty model. It features a larger filtration system with a prefilter, carbon filter, and HEPA filter that last 12 months before replacement. The unit is CARB-certified and can clean up to 1,800 square feet in one hour. It includes a real-time AQI monitor with MegaScan laser detecting PM 1.0, 2.5, and 10 particles. The Mighty2 has smart mode that adjusts fan speed based on air quality and enters sleep mode when dark for three minutes. It offers timer settings from 1 to 12 hours. The reviewer tested it for three weeks in various rooms, noting improved air quality near litter boxes, kitchen, and windows. In smoke tests, it cleared visible smoke in 50 seconds and returned to healthy air in 3 minutes 20 seconds. Noise levels ranged from 35 dB on sleep mode to 65-70 dB on highest setting. The reviewer appreciated the auto-adjusting smart settings but noted the lack of wheels, app connectivity, and remote control. At $30 more than the previous model, the Mighty2 offers longer-lasting filters and better performance for smaller living spaces.
