1 Inch Slot Dual Filtration Furnace Filter for 22x24x1 Inch HVAC Systems

Cleaner home air means fewer allergy symptoms and less house cleaning! Replace your standard one inch furnace filter with the Safe Home™ Duo air purifier filter combination. This twin filter media furnace filter captures dust, dirt, pollen and chemicals plus odors. This 22 by 24 by 1 inch MERV 8 air purifier furnace filter fits any standard 1 inch filter slot. In a few days you'll notice the difference!

Note: Check with your HVAC technician to verify that your system is able enough to handle the density of a MERV 8 filter before purchasing this or any other MERV 8 filter. Install this MERV 8 with Air Flow First Going through the White Media. Made in USA


The Safe Home™ Duo uses a combination of two filters with an internal metal frame: the air slot is sealed 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: 22" 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.
