According to the EPA, Americans spend up to 90 percent of their time indoors. Children and the elderly are especially sensitive to air pollution. Most pollutants are microscopic and can easily pass through the nose or throat directly into the lungs. Air Purifiers are designed to help remove airborne particles and odors as the air passes through the filters helping to remove pollutants, allergens, and other contaminants from the air you breathe. After the air is filtered a powerful fan quietly distributes the clean air back into the room.
