The 14x20x1 MERV 11 air filter’s efficiency ratings are ideal upgrades for spaces that require a bit of extra filtration for a higher degree of fresh, clean air. MERV 11s are great for homes with multiple pets, people with respiratory issues and allergy sensitivities, commercial office buildings, retail stores and public spaces. A MERV 11 filtration rating allows for great air flow in your heating and cooling system while providing excellent protection. The efficiency provided helps reduce costly repairs and offers great savings on energy costs. MERV 11 rated air filters reduce pet dander, dust mites, smoke, smog, dust, pollen mold spores, bacteria and other allergens, generating fresh, clean air for your home or business. The MERV 11 is based on ASHRAE Test Standard 52.2-2012. This pleated air filter improves performances for any and every application. All filters utilize fibers which do not support microbial growth, and do not absorb moisture. These fibers keep your filters working harder, longer! 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. Engineered and designed for high strength and rigidity, these filters are independent quality control tested, with heavy duty moisture resistant frame. 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 heavy duty, recycled expanded metal reinforcement 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. This design and manufacturing process results in high performing, high quality air filters that can withstand temperatures up to 180°F. It is recommended that filters be replaced at least every 90 days, 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.
