Choose this MERV
for maximum air filter performance in your 1 inch by 15 x 20 inch HVAC
filter slot. Safe Home™ furnace filter
for HVAC systems
uses two layers of filtration
. First air filter media is white polyester for air purification
, mold and dust. Second layer has activated carbon filter
material plus potassium permanganate to
capture odors and harmful chemicals. The Duo's superior design has self sealing edges with an inner steel frame. The edges help 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. Note: Always Check with Your Furnace Technician to Determine the MERV rating of the Filter to Use in Your System. 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:
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 .
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.
