12 by 24 by 1 inch Safe Home™ furnace filter for HVAC filter use is made with two layers. Air flows first through white polyester for air purification of pollen, mold and dust. Then, through an activated carbon filter material with potassium permanganate to capture odors and harmful chemicals. Self sealing edges with an inner steel frame: all air goes through the filter. Lasts up to 3 months. Note: 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 outer layers are made with polyester and 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. This is the most effective filter on the market at removing dust mites, mold spores, pollen, odors, cleaning chemicals, ozone, paint fumes, and common gasses like formaldehyde which triggers asthma and allergies.
The SafeHome Duo utilizes polyester layers as a prefilter and uses carbon and FormaldaSorb injected fibers for further filtration
. This filter design uses mechanical filtration which offers the advantage of increased filtration efficiency over time because the particles themselves become part of the filter and there is no reliance on electrostatic charges which degrade over time. Mechanical filtration is particularly advantageous in humid areas or near kitchens because humidity and vapors significantly degrade pleated air filters’ electrostatic charge. By containing multiple densities of material, Duo filters are able to capture more particles while maintaining proper air resistance. Safe Home Duo Filter Features:
- Dimensions: 12" 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™ traps hazardous gasses
- Highly effective and affordable
Note: 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.
