Summary: After researching several products, this unit had all the features we were looking for, clean air, removal of dust mites, pollen and several other air and humidity problems. It is whisper quiet, very easy to clean and put water into it. Easy to read instructions. It's expensive, but worth every penny.
Summary: One button, unit is fully automatic for cleaning the air and also for humidification. Easy to fill, the unit self monitors and you can see the gage react when the air quality gets bad. i.e. when I burn a pizza.
Pros: Attractive Design, Long life, Quiet, User friendly
Summary: I purchased this product mainly for its humidifier function, and was hoping it could perform as well or better than my Air-O-swiss 7144, which it does. My Air-O-swiss 7144 struggled to get my humidity level to a manageable state >30%, the sharp plasmacluster achieves this with no problem, while at the same time filtering my air. Maintenance frequency and cost of ownership is great on the plamsacluster, filters are washable and last 2 (charcoal) and 5 (HEPA) years.
Pros: Affordable, Attractive Design, Quiet, User friendly
