MD1-0045 True HEPA Filter Cartridge

Over time, your HEPA filter begins to clog, reducing the amount of air that is filtered. To maintain true Whole Room Air Purification, it is imperative to change your filter every 6 months, depending on use, using only genuine Sharper Image filters. Others may claim to be compatible with Sharper Image units, but our Sharper Image Air Purifiers are only tested to achieve a 99. 97% capture rate using a Sharper Image HEPA filter. For filter replacement instructions, see your owner’s manual. This 3-in-1 True HEPA Filter Cartridge, part number MD1-0045, works with PURIFY 5.
