Be sure your home's air is clear of dust, pollen, fungi, smoke and other particles too small to see. It's easy with a HEPA, Electronic or Media Air Cleaner. These cleaners provide stepped-up filtration, more effective than your furnace or air conditioner alone. In fact, these cleaners can remove up to 94 percent of the particles that pass through your home's system. And since these pollutants can build up as film on walls and furniture, this is performance you'll feel and see.
