Overview

The Sharp KC-860U Air Purifier with Humidifier is engineered for large living spaces up to 1,650 square feet, combining three-stage filtration with active Plasmacluster Ion Technology. The filtration process begins with a washable microscreen pre-filter that traps dust and large particles, followed by an activated carbon deodorizing filter that helps reduce common household odors, and culminates with a True HEPA filter that captures 99.97% of airborne particles 0.3 microns and larger from the air that passes through it. This layered approach addresses everything from pet dander and pollen to smoke and everyday odors.

Beyond passive filtration, the KC-860U features Sharp's Plasmacluster Ion Technology, which disperses positive and negative ions into the air for active cleaning — a technology that has been tested by independent laboratories worldwide. The integrated humidifier adds another layer of comfort, with an Auto Mode that monitors both air quality and humidity levels, adjusting output automatically to maintain a healthy indoor environment. With multiple fan speeds including Quick Clean and Pollen modes, plus filters designed to last up to five years, the KC-860U is built to deliver sustained, low-maintenance air quality improvement for large rooms.

Key Features

HUMIDIFIER: Auto Mode monitors air quality and adjusts air purification and humidity levels.

TRIPLE FILTRATION: The triple filtration system helps clean the air that passes through the filters in three ways. First, the washable, microscreen pre-filter traps dust and other large airborne particles. Second, the activated carbon deodorizing filter helps reduce some common household odors. Finally, the True HEPA filter effectively captures 99.97% of particles from the air that passes through the filter that are 0.3 microns and larger.

ACTIVE CLEANING: Beyond triple filtration, our KC860U features Plasmacluster Ion Technology for an active cleaning process. Sharp Plasmacluster Ion Technology has been tested by laboratories around the world.

LONG LIFE FILTERS: Includes an Activated Carbon Deodorizing Filer, a Long-Life True HEPA Filter, and a Humidifying Filter that may last up to 5 years depending on the environment.

3-FAN SPEEDS PLUS QUICK CLEAN: Max, Med, and Low Fan Speeds, plus Pollen, Quick Clean and Auto Modes.
