Safe Home Duo One Inch Thick Filter Installation:
Determine direction of air flow through your furnace.
Fold excess filter media around internal steel frame.
Slide Duo Furnace Filter into the one inch slot so air goes first through the white pre-filter.
Tuck in any excess so you can place cover, if any, over the end
of the filter slot. Note: excess material helps seal edges to force all
air through the filter.
Change the Duo air filter at least every 3 months. Some
conditions that feature pets, construction work, painting or smoking may
produce more pollutants and require more frequent changes.
Note: This furnace filter is not a control device for radon, carbon monoxide or carbon dioxide.

Air should enter the white side, which traps allergens, and exit through
the dark side, which traps gases and odors.

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.
