This pleated air filter improves performances for any and every application. The HVAC filters are moisture resistant, and do not allow growth of mold, bacteria, and microbial. High quality synthetic nano fibers continue to perform longer where optimal filtration is required, and provide high performance with low pressure drop for excellent energy efficiency. Engineered and designed for high strength and rigidity, these filters defend from Lint, Dust, Pet Dander, Pollen, Dust Mites, & Mold. Independent quality control tested, with heavy duty moisture resistant frame, these filters are available in several standard face sizes. All media used in the manufacture of these filters are made of 100% synthetic fibers, using a tapered radial configuration. A Sturdy, hardy expanded metal backed grid frame is laminated to the air-exit side of the filter by a heat-setting adhesive to ensure consistency or the radial pleats. This expanded metal is also galvanized to deter rust and corrosion. The pleated cartridge is bonded to the peripheral interior of a heavy-duty, moisture resistant beverage board outer frame. The development and production procedures results in high performing, high quality air filters that can withstand temperatures up to 180°F. Common industry standards suggest that air filters be replaced at least every 3 months, but they may need to be changed more often based on a variety of factors. Pets, poor air quality, respiratory issues and a number of other factors can affect the rate at which filters should be changed.
