MERVPLUS, MERV 11 Pleated Filter - 4" - Aprilaire Generic

High Capacity Pleated Air Filter - constructed utilizing synthetic, electrostatically charged MERV 11 performance at a very low, energy saving pressure drop - setting the standard for performance. Mechanical media - does not rely on a static charge to achieve efficiency rating High Efficiency - cleaner air to breath Heavy duty, 100% reclaimed fiber, beverage board frame with expanded metal backing providing exceptional strength High Capacity model: more pleats = longer service life This product is an upgrade from a typical MERV 8 furnace filter Price per filter, 6 Filters per case Advantages High resistance to impurities Small pressure drop for high energy efficiency Excellent bi-directional efficiency High capacity to retain dust for a longer lifespan Continuous fibres to avoid erosion Thermally sealed, no chemical additives High dimensional stability in moist environments Non-favourable to bacterial or fungus growth Filtration Power MERV 11 means that the filter can stop 50% of particles larger than 1 micron and 90% of 10 microns particles. This includes among others: Particles of 1 to 3 microns (50% captured) Legionella Humidifier dust Lead dust Grounded flour Car emissions Soldering fumes Particles of 3 to 10 microns (±75% captured) Mold spores Hair spray Cement dust Pudding mix Powdered milk Particles of more than 10 microns (90 captured) Pollen Mites Sawdust Paint fume Fabric fibres Carpet fibres Construction Totally synthetic fibre material Metallic mesh reinforcement Moisture proof frame Filter material glued to frame UL Class 2.3360 Listed Tested in accordance with ASHRAE 52.2
