Sharp's FP-A28UW air purifier combines True HEPA filtration to reduce allergens with Sharp’s patented Plasmacluster® Ion technology which attacks germs and odors. Available at AppliancesConnection


The Plasmacluster air purifier helps remove these irritants with an ultra-quiet fan that draws air through a washable pre-filter and a True HEPA filter that removes 99.97% of impurities from the air that passes through it. This filter system plus the revolutionary Plasmacluster Ion Technology for air purifiers makes the air cleaner and fresher smelling. Sharp’s Plasmacluster Ion technology attacks germs and odors at the molecular level. This technology has been proven to reduce certain bacteria, virus, mold, fungus and odors in lab tests.


Washable Pre-Filter
Traps dust, dirt and other airborne particles.

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.

Plasmacluster Ion Technology
Sharp’s patented technology splits water molecules into positively and negatively charged ions, which spread throughout the room, surrounding airborne impurities and breaking them down. This technology has been proven to reduce certain bacteria, virus, mold, fungus and odors in lab tests.

Simple Touch Operation
Lets the user choose among 3 fan speeds.

Plasmacluster Ion Mode
Can be switched manually On or Off. Maintains the natural ion balance in the room.

Library Quiet™
Operation is ideal for bedrooms and living rooms. Silent Mode is as quiet as 27 decibels, about the volume of rustling leaves. This is one of the quietest air purifiers with a HEPA filter available anywhere.

Energy Efficient
Operation means it's easy on your wallet. With its advanced technologies, it is 40% more energy efficient than standard models, making it ENERGY STAR® qualified.

Long Life HEPA Filters
Require changing only once every 2 years so operating costs are low.
