DESC: Honeywell’s HFD-110 QuietClean tower air purifier offers superior air-cleaning power with HEPA performance. The permanent filter removes up to 99 percent of airborne particles such as dust, pollen, smoke, and pet dander, returning cleaner, fresher air to your room. Compared to ionic air purifiers, the filter from the HFD-110 captures 12 times more pollutants, and a powerful but quiet fan pulls air into the unit, circulating and filtering the air in your room several times each hour.
