Air Purifier & Humidifier with HEPA Filters - Medium Room

Overview

Air quality in a bedroom affects sleep quality more directly than most people realize. Dust particles, pet dander, pollen, and VOCs all contribute to airway irritation that can disrupt the depth and continuity of sleep — especially for light sleepers.

The Sharp KC-850U combines a True HEPA air purifier with a humidifier function in a single unit. The three-stage filtration system removes particles down to 0.3 microns. Plasmacluster Ion Technology actively neutralizes airborne contaminants between filter passes. The integrated humidifier auto-adjusts based on room conditions — maintaining optimal humidity alongside clean air.

Designed for medium rooms up to 254 sq ft. Filters rated for up to 5 years. Sleep mode reduces fan speed and dims the display for nighttime use.
