Details & Features

The Sharp KC850U is a great humidifier for 250 sq. ft. rooms, adding humidity to the air for improved air quality and maximum comfort, especially in colder weather. It also helps reduce static electricity that results from dry air.

The intelligent front display shows Plasmacluster™ operation, dust monitor, humidity level, and an indicator light to determine when the water tank needs to be refilled.

The includued True HEPA KC850U Filter captures 99.97% of particles as small as 0.3 microns that pass through it, including pollen, mould, pet dander and dust. The special Antimicrobial Layer provides extra protection against viruses.

Plasmacluster™ Technology splits water molecules into positively and negatively charged ions, which spread throughout the room, surrounding airborne particles. This system effectively restores the natural balance of ions in the air, like near a waterfall or just after a thunderstorm. This restored balance helps refresh the air and leaves it cleaner smelling.

The KC850U is easy-to operate with "Instant On" buttons for Clean Air, Clean Air & Humidify and Quick Clean mode.

An Active Clean Air Indicator shows the level of impurities in the air by colour so it's easy to see the progress as it returns healthier, cleaner air into the room.

Manual Operation lets the user choose among 3 fan speeds, plus Pollen and Quick Clean modes.

Automatic Operation uses the sensor to automatically adjust fan speed for the degree of cleaning required.

Plasmacluster™ Ion Mode can be switched between Clean Mode/Ion Control Mode and Auto mode automatically. Maintains the natural ion balance in the room.

With Library Quiet™ operation is ideal for bedrooms and living rooms. Silent Mode is as quiet as 23 decibels with humidifier on, about the volume of rustling leaves. This is one of the quietest Air Purifiers with a HEPA filter available anywhere.

The KC850U's energy efficient operation means it's easy on your wallet. With its advanced technologies, it is 35% more energy efficient than standard models, making it ENERGY STAR™ qualified.

Ultra Long-Life HEPA Filters -- The KC850U filter requires changing only once up to every 5 years depending on your environment so operating costs are low.

SHARP Plasmacluster™ Active Ion Technology has been used in over 100 million products worldwide, including leading auto makers and appliance manufacturers. It's no wonder people around the world trust SHARP. Now that is Simply Better Living.
