Dual Layered HVAC Air Filter with Internal Frame, Polyester Filter and FormaldaSorb™

Safe Home Duo 2025 captures dust, dirt and orders! Remove allergens, odors and harmful chemicals. 4 pack of Safe Home disposable furnace filters by Safe Home™ . Each furnace air purifier filter fits a slot 20 by 25 by 1 inch or a return air grille of the same size. The Duo air filter for HVAC systems has an internal frame with self sealing edges: two layers, one for pollen, mold, ,etc and the other that absorbs odors and chemicals from return air from your house. Use for 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:
  • Dimensions: 20" x 25" x 1"
  • Captures up to 95% of common household allergens
  • Eliminates odors from pets, paint, cooking, and more
  • FormaldaSorb™, a patented potassium permanganate product plus the activated carbon in the second layer of the filter trap gasses that can cause health issues.
  • Highly effective and affordable.
  • 2 stage air filter: one MERV 8 rated polyester white allergen filter plus the activated carbon filter pad.
  • Made in USA.
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.
