Year's Supply of HVAC Furnace Filters

For most homes and businesses, this pack of 4 HVAC filters will last a year.  The Safe Home™ Duo air purifier filter combination is MERV 8 rated plus filters out odors and pollutants such as formaldehyde. Each 20 x 24 x 1 inch furnace filter has two filter medias packages in one around an internal metal frame. The MERV 8 filter is for dust, dirt and pollen allergens plus the second layer is for odors and chemicals. This furnace air filter fits any standard 1 inch filter slot.  Leave your blower on full-time and notice the difference in a few days!

The Safe Home™ Duo has two filters with an internal metal frame: the air slot seals tightly so dirt cannot go around it. This furnace filter looks different from a standard furnace filter for a simple reason, it is . The Duo is the only home air replacement filter to capture allergens, odors, and harmful chemicals and fit in a standard one inch furnace panel slot or a return air grille with removable face for filter insert. The Duo features a superior design with self sealing edges which maximize its effectiveness at capturing allergens, odors, and chemicals from the air in 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.

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 24" x 1"
  • Captures up to 95% of common household allergens
  • Eliminates odors from pets, paint, cooking, and more
  • Uses high density carbon and advanced compounds
  • 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.
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.

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.
