Know the MERV Rating of Your Current Filter. Install this MERV 8 with Air Flow First Going through the White Media.  Made in USA.

Use for HVAC furnace filter slots, temporary needs, or custom sizes in air return grills. Duo replaces any 1" thick home air filter: can last up to 3 months.

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:
  • Dimensions: 20" x 20" x 1"
  • Captures up to 95% of common household allergens
  • Eliminates odors from pets, paint, cooking, and more
  • FormaldaSorb™, a patented potassium permanganate product (6% P P) plus activated carbon 50/50 blend of 60% CTC coconut shell carbon and Zeolite 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.
