A carbon filter sets how odors and VOCs are handled, a HEPA filter sets which particles are captured, and a pre-filter sets what gets caught first. The WINIX gives a carbon filter with True HEPA and a washable pre-filter, the COWAY gives a deodorization filter with HEPA, and the AirHub gives a carbon pellet filter with True HEPA and a washable pre-filter. Compare carbon and HEPA filters with the odors and particles in your rooms.
Noise, speeds and control
Noise sets how loud a purifier runs, speeds set how much control you have over airflow, and control sets whether you use an app or touch buttons. The WINIX gives app control with auto mode. The COWAY gives 20 dB noise with 3 speeds, and the AirHub gives 20 dB sleep noise with auto mode. Compare noise and control with where the purifier runs.
Coverage, weight and warranty
