in any location and can last up to 3 months. Note: Check with your HVAC Tech prior to replacing your filter. Make sure an older system can handle a MERV 8, the current filter for most applications. 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. Installation Instructions:
The white side of the filter should face incoming air. In most systems, the white side should face 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.
