Best thing: High CADR for its size
Honest catch: No Wi-Fi or app control
For a living room, open kitchen-diner or large bedroom, the Mighty gives you more cleaning power than compact bedroom purifiers, with automatic speed control and an energy-saving Eco mode. It is boxier than a tower, has no app, and you will replace two filters — the deodorization filter every 6 months and the HEPA filter yearly.
Sized for living spaces: Coway rates it for 361 ft² at 4.8 air changes an hour, or 874 ft² at two.
Four-stage filtration covers seasonal allergens, pet dander and wildfire smoke, with a dedicated deodorization filter for odors.
Hands-off cleaning: the air-quality indicator drives Auto mode, which adjusts the fan in real time as particle levels change.
Saves energy: Eco mode turns the fan off after 30 minutes of clean air and restarts it when pollution is detected.
Quiet when it can be — as low as 24 dB — with a 1, 4 or 8-hour timer.
Clear upkeep: a filter-change indicator, a washable pre-filter and set replacement intervals.

Coway rates it for 361 ft² at 4.8 air changes per hour, 874 ft² at two and 1,748 ft² at one. For noticeably cleaner air — especially with allergies — size it by the 361 ft² figure.
Coway lists 6 months for the deodorization filter and 1 year for the HEPA filter, and a filter-change indicator reminds you. The pre-filter is washable and reusable.
If the air stays clean for more than 30 minutes, the fan switches off to save energy, then restarts automatically when the sensor detects pollution again.
