Pulls Germs, Odors & Allergens Out of the Air Like a Magnet! The Pro Shield Air Purifier is the smart, simple and energy efficient way to clean the air in your home and help protect your family. Powerful and portable with the ability to lay flat or on its side, it can be easily moved from room to room, where kids and animals play, where smokers gather, or where mold and other allergens are a concern. The EPA says indoor air may be up to 5 times more polluted than the air outside. The ProShield® Plus Air Purifier is an easy, portable, proactive way to help capture allergens from the air that passes through the filter — plus, break down odors and volatile organic compounds from the air that passes through the filter.
