Safe Home™ Duo4 filters
are the only
home air replacement filters to capture allergens, odors, and harmful chemicals. Gaskets around the edges mean maximum effectiveness at capturing allergens, odors, and chemicals from the air in your house. Use for furnace filter slots, temporary needs, or custom sizes in air return grills. The Duo 4 lasts up to 9 months. How does the Duo4 work?
The polyester outer layers remove pollen, mold spores, and other common allergens. The inner layer features FormaldaSorb™ and activated carbon to trap 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 Duo4 Filter Features:
