Year's Supply of Allergy Furnace Filters Are 16 x 25 x 1 with Interna l Frams
This four-pack of 16 inch by 25 inch by 1 inch Safe Home™ MERV 8 airpurifier furnace filtersare enough for a year's worth of cleanair in the average home or business. Each Safe Home Duo has two filters around an internal metal frame. Note: Always check with your HVAC technician before changing from your current furnace filter. This unit is a MERV 8. Made in USA.
The Duo is the only home air replacement filter that captures allergens, odors, and harmful chemicals and fits in a standard one inch furnace panel slot or a return airgrillewith removable face for filter insert. The Duo has a superior design with self sealing edges to maximize its effectiveness at capturing allergens, odors, and chemicals from household air. 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.
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
