The HEPAClean® Compact Air Purifier offers low maintenance, effective air cleaning with a long-life vacuum-able HEPA-Type filter. The 3-stage filtration system first helps clean the air by using a washable pre-filter to capture larger airborne particles. It then passes through the long-life HEPA-Type filter, capturing up to 99% of microscopic particles such as mold spores, pollen, pet dander, smoke and dust*. The filtered air then enters an ionizer field providing extra cleaning and air freshening. This model features 3 cleaning power selections and an electronic filter clean indicator to remind you when to vacuum or replace the filter. For added convenience, it can be placed in a horizontal or vertical position to be used virtually anywhere - tabletop, counter, floor or nightstand. This model is most effective in small size rooms and is ideal for the nursery, bedrooms, kitchen, office or den. 99% Efficient, Long-life vacuum-able HEPA-Type Filter 3 cleaning power selections
