Installation Instructions: White side of the filter should face incoming air. In most systems,
the white side faces away from the air handler or furnace
equipment. 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. Safe Home Duo Filter Features:
