The SHARP KC850U combines True HEPA air purification with a built-in humidifier for medium rooms, recommended for areas up to 254 sq. ft. and effective up to 1,230 sq. ft. at one air change per hour. The True HEPA filter captures 99.97% of particles as small as 0.3 microns that pass through it — pollen, mould, pet dander and dust — and adds a special antimicrobial layer for extra protection against viruses, while an active carbon filter absorbs many common household odours. The humidifier puts out 1.3 pints per hour, improving comfort in colder weather and reducing static electricity from dry air. Plasmacluster® Ion Technology restores the air’s natural ion balance, an Active Clean Air Indicator shows impurity levels by colour, and Library Quiet™ operation runs as low as 23 dBA.
