Product Description

Sharp’s new Plasmacluster™ Air Purifiers with humidifying function offer a unique combination of air treatment technologies to make you and your family more comfortable, whatever the season. Bacteria, germs, mold spores, pollen, pet dander, smoke, dust and odors can make breathing harder, especially for asthma and allergy suffers. These air purifiers help remove these irritants from the air that passes through it with an ultra quiet fan that draws air through a three-stage filter system. Plus, their revolutionary Plasmacluster Ion Technology actively refreshes the air. For an even more comfortable environment, when the Pasmacluster Air Purifier is on, its sensors constantly monitor the air quality in your room, adjusting the fan for air purity while providing the optimum humidity level. This combination of features is a smart way to choose cleaner, healthier, more breathable air. - Clean Sign Indicator shows the level of impurities in the air passing through the filter so it’s easy to see the progress as healthier, cleaner air is returned into the room. - Plasmacluster Technology splits water molecules into positively and negatively charged ions which spread throughout the room. This system effectively refreshes the air similar to the way nature cleans the environment near waterfalls or just after a thunderstorm. - True HEPA Filter captures 99.97% of particles as small as 0.3 microns from the air that passes through it, including pollen, mold, pet dander and dust. - Library Quiet™ operation is ideal for bedrooms and living rooms. Silent Mode is as quiet as 17 decibels, about the volume of rustling leaves. - Energy Efficient operation means it’s easy on the wallet. With its advanced technologies, it is 35% more energy-efficient than standard models, making it ENERGY STAR® qualified. So it can operate all the time, saving money while improving the quality of the air.

This review is from: Sharp KC-850U Plasmacluster? Air Purifier with Humidifying Function for up to 254 square-foot room (Kitchen)

If you're looking for a nearly silent purifier, this unit does it. Granted you need to keep it on low for those super-quiet noise levels.

Pros:
* Filters extremely well
* Quiet
* Water tank easy to remove
* LED lights can be turned off

Cons:
* Water tank empties in 8 hours on low, less on higher fan levels
* Water tank doesn't have a handle for holding it "upside down" while filling. Makes it slightly more awkward when filling in the tub bent over.
* Unit is decent sized and is floor model. It's no huge, but it's not small either

The unit also has LED's the purport to tell you how "clean" the air is... how many particles are floating in the air. My house gets quite dusty, but I've still never seen the unit display anything but "all green" on this display. Perhaps it doesn't work on my unit, or perhaps it doesn't work well. And it's this gauge which makes the unit go into a higher fan mode when the air is dirty and the unit is in auto mode. So my unit never leaves low fan. So at this point I manually turn it to medium or high when I'm not in the room.

I'm not sure if it's worth the price here on Amazon, > $350 currently. But I also have never purchased another purifier. Maybe it does work much better than the competition and is worth that price. However I found the unit on clearance at Best Buy and paid less than $200. At that price point, I consider it a worthwhile investment.
