™ furnace filter
is 14 by 14 by 1 inch. Use for homes or businesses in cold air return grilles with filter slot. MERV 8 Safe Home ™ air purification filter
with internal metal frame, not a paper frame. Not pleated paper: polyester outer layer. The Safe Home ™ Duo filters furnace air
through two layers. The air purification
efficiency is increased due to self sealing edges which maximize its
effectiveness at capturing allergens
, and chemicals from the air
in your house. Use for furnace filter
slots, temporary needs, or custom sizes in air handler
return grills. The Safe Home ™ Duo
is the only home air filter
that is one inch thick that captures allergens, odors and harmful chemicals. The Duo replaces any 1" thick home air filter
in any location and can last up to 3 months. 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. 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 trap 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. The duo action filters are the most effective filters 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 Furnace Filter Features:
Safe Home ™ Duo One Inch Thick Filter Installation:
