This nickel finish** **GE Ionizing Air Purifier has a PERMAtech filter that never needs replacement and is easy to clean. HEPA-type filtration removes up to 99% of airborne particles (dust and pollen) as small as two microns for an area up to 180 sq ft. It has three speed settings, optional ionizer and filter service indicator. It is lightweight and extremely easy to move around the room. I've owned this purifier for over five years and it never misses a beat! Works great at filtering out smoke and cooking odors.
