Our 18x18x1 MERV 8 Air Filter is simple to install, easy to use and optimized for most air filter conditions. This MERV 8 HVAC furnace filter is manufactured to shield your home or business’ HVAC system from most airborne particles. The filter also blocks pollen and allergens which aggravate seasonal allergies, improving the health of inhabitants by breathing cleaner fresher air. The HVAC filters are moisture resistant, and do not allow growth of mold, bacteria, and microbial. These fibers keep your filters working harder, longer! Designed to improve performances for any and every application, pleated air filters are ideal in systems where maximum square footage of filtration is needed, and provide high performance with low pressure drop for excellent energy efficiency. Defending from Lint, Dust, Pet Dander, Pollen, Dust Mites, & Mold, these air filters are engineered and designed for high strength and rigidity. Available in several standard sizes, these filters are independent quality control tested, with heavy duty moisture resistant frame. 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. While filters may need to be changed more often based on a variety of factors, it is generally recommended that these filters be replaced at least every 90 days. Pets, poor air quality, respiratory issues and a number of other factors can affect the rate at which filters should be changed.
