filters to capture allergens, odors, and harmful chemicals. Duo's superior design includes self sealing edges to maximize effectiveness at capturing allergens, odors, and chemicals from the air in your house. Uses include furnace filter
slots, temporary needs, or custom sizes in air return grills. The Duo replaces any 1" thick home air filter
in any location and can last up to 3 months. Always check with your HVAC technician before changing from your current furnace filter. This unit is a MERV 8. Made in USA. How does the Duo work?
- The polyester outer layers remove pollen, mold spores, and other common allergens
. The inner layer features FormaldaSorb™ and activated carbon that traps a variety of odors
and hazardous gasses, such as formaldehyde, ammonia, and others that are emitted by cleaning chemicals, paint, particle board, and other household items. No other filters are as effective at removing dust mites, mold spores, pollen, odors, cleaning chemicals, ozone, paint fumes, and common gasses like formaldehyde which triggers asthma and allergies. Safe Home Duo Filter Features:
Change the Duo at least every 3 months. Some conditions that feature pets, construction work, painting or smoking may produce more pollutants and require more frequent changes. Limited Warranty: Free of manufacturing and material defects. If product is found defective within 30 days of purchase, it will be replaced at no additional charge.
