Enjoy cleaner, more breathable indoor air with this convenient air cleaner. Designed for large-size rooms up to 160 square feet (about 13 by 12 feet), the unit's permanent HEPA-grade filter effectively removes up to 99 percent of all airborne allergens including mold spores, pollen, pet dander, and more. Choose from three ultra-quiet speed settings. The unit also provides a compact, tower shape that can be positioned vertically or horizontally for use on a desk, nightstand, bookshelf, or anywhere throughout the home. Its permanent filter means no replacement filters to buy. Even more, the permanent filter can be vacuumed clean--no need to touch another dirty filter. Other highlights include a simple control knob, a stable base, and a sleek modern look that will blend in nicely with any decor. The allergen-reducing air cleaner measures 8-1/2 by 6 by 13-1/2 inches.
