Safe Home™ Duo Disposable One Inch Furnace  Filter,2 Media Layers, Internal Frame

Safe Home™ SH-DUO-1420 is a twin layered 20 by 14 by 1 inch disposable furnace filter with internal frame for a tight fit in a one inch furnace filter slot. Safe Home Duo air purifier furnace filter looks different from standard 1 inch furnace replacements. 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.

HVAC air filter has two air purification filters covering a steel frame. The white polyester pre-filter capture allergens, the black 50/50 potassium permanganate and activated carbon filter removes odors, and harmful chemicals. Self-sealing edges keep air from going around the filter. Use for one inch 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.

Safe Home Duo Furnace Filter, Dual Media, Internal Frame Features:
  • Dimensions: 14" x 20" 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.
  • Twin filter pad: MERV 8 polyester white ASHRAE rated allergen filter plus an industrial chemical and odor filter, i.e. the activated carbon filter pad.
  • Internal Metal Frame: no air goes around filter
  • Made in USA.
How does the Duo work? - The polyester outer layer removes 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 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.
