Sharp KC850U Plasmacluster Air Purifier & Humidifier — HEPA, 250 sq. ft.
Breathe Cleaner, Comfier Air — Without the Noise
Dry winter air and invisible airborne irritants make your home harder to live in than it should be. The Sharp KC850U tackles both at once: it actively cleans the air and rebalances humidity for rooms up to 250 sq. ft. — so bedrooms and offices feel fresher, calmer, and easier to breathe in.
Why people choose the KC850U
- Plasmacluster® ion technology — actively neutralizes odors and airborne bacteria throughout the whole room, reaching what passive filters miss.
- True HEPA filtration — captures 99.97% of particles down to 0.3 microns: pollen, dust, dander, and mold spores.
- Smart humidification — senses dry air and adds moisture automatically to ease breathing and cut static.
- Library-Quiet™ mode — as low as 23 dB (quieter than a whisper), so it disappears into the background at night.
- ENERGY STAR® certified — ~35% more efficient than standard models, with long-life filters rated for roughly 5 years.
Built for everyday living
