About this item

The FreAire KN6391RGB is a HEPA air purifier built for bedrooms and larger rooms up to 1086 ft². Its 3-stage filter traps fine particles, smoke, pet dander, and odors, while the dual-channel intake and 360° outlet push clean air through the space quickly. At night, sleep mode quiets operation down to 20 dB, and you can add a few drops of essential oil to the aroma pad for a light scent. Three ambient lighting options let it double as a night-light.
