The EPA says indoor air may be 5 times more polluted than the air outside, and most of us spend approximately 90% of our time indoors. If you have weather-tight doors and windows, pets, or smoke, you could be adding to the problem. That’s why you need the new, whisper-quiet¹ ProShield Air Purifier – the easy, portable, proactive way to help clean the air in your home. It circulates the air, filters out allergens, dirt, and other airborne irritants, captures and kills viruses and germs, and breaks down odors and volatile organic compounds such as chemical fumes and aerosol vapors.
