Sharp Plasmacluster KC-850U Room Air Purifier User Review and Ratings

• air is pure

  Very good at cleaning air. Highly recommended.Much quieter than Honeywell. Accurate detection of particles.It can be used effectively on the "quick clean" setting to purge the air of contaminants. Then by placing it near the door, it can function as an airlock.

• an innovative air purifier

  So many air purifiers in the $100 to $300 range are essentially the same thing: fan + HEPA filter + carbon pre-filter. You'd think for that much money there would be more to it. On top of that the designs are typically more industrial than consumer oriented. While Sharp KC-850U at its core is still just HEPA + carbon prefilter, it's leaps and bonds better in all the other regards than the market norms.Pro:* The embossed front panel design looks clean and modern* It has sensor that monitors air quality and humidity and adjust itself accordingly* LED light's brightness can be adjusted and turned offCon:* The humidifying functionality is rather weak, it's not enough to replace my stand alone humidifier in the living room* replacement filters are expensive, according to the manual the HEPA filter (around $100) and carbon filter (around $60) good for 5 years, humidification filter ($35) is good for 2 years. You can wash the carbon filter and humidification filter, but in my experience they can only be washed so many times before they wear out.* These Sharp air purifiers are far from mainstream, makes me worried how long I'll be able to purchase the filters before they are discontinuedI'm tempted to -1 star for the lackluster humidification performance, but the unit is so well designed with great attention to detail comparing to everything else I've seen, it deserves a 5.

  Love this plasmacluster purifier in my bedroom really keeps air clean. I also like the fact I can use as air cleaner or dehumidifier.

  This thing is awesome. I got it because my NYC apartment is full of stagnant, dry air in the Winter (and crappy window unit AC air in Summer), and I wanted to get a better night's sleep. Kid you not, this thing most definitely changed the air quality of my room and I definitely look forward to going to bed now :)

  The newer models are quieter but this model does a very good job of controlling air quality and humidifying the air.
