Yaning Factory Direct High Quality Clean Living Dust Reduction HVAC Furnace Air Filter Glass Fiber HEPA Air Filter

Product DescriptionHEPA is a type of pleated mechanical air filter. It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. of Energy).  This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). The diameter specification of 0.3 microns responds to the worst case; the most penetrating particle size (MPPS). Particles that are larger or smaller are trapped with even higher efficiency. Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97% or better for all particle sizes).So if HEPA filters were invented in the 1940s, and they're nothing fancy, then what makes any old filter a HEPA filter? Turns out using the term "HEPA" has a strict set of requirements. In Europe, HEPA filters must remove 99.95% (ISO) of particles. In the US,they must remove 99.97% of particles.When following the ISO or European rules, filters that capture ≥85% of particles but less than 99.95% are called 'EPA filters' or 'efficient particulate air filter'. These air filters do not meet the filtration requirement to be considered a 'HEPA air filter'.All air cleaners require periodic cleaning and filter replacement to function properly.  Follow manufacturer's recommendations on maintenance and replacement. MERV RatingAverage Particle Size Efficiency in Microns1-43.0 - 10.0 less then 20%63.0 - 10.0 49.9%83.0 - 10.0 84.9%101.0 - 3.0 50% - 64.9%, 3.0 - 10.0 85% or greater121.0 - 3.0 80% - 89.9%, 3.0 - 10.0 90% or greater140.3 - 1.0 75% - 84%, 1.0 - 3.0 90% or greater160.3 - 1.0 75% or greaterDetailed PhotosCertificationsPackaging & ShippingStretch film strapped whole cabinet,Foam inside protected,Plywood case solid fixedCompany ProfileDongguan Yaning purifucation Technology Co.,Ltd.islocated in Dongguan city Changan ,is a set design development, production,sales, construction professional installation services in one purifier manufacyurers,the company is committed to the purificationindustry for more than ten years,the South China purification technology industry's most Powerful enterprises.the main products used in health care,electronices technology ,bio-medicine ,food,precision instruments aerospace,automoble manufacturing and many another areas.products:1.FFU ,air shower room ,cargo air shower ,HEPA filter ,horizontal clean bench ,pass box ,clean booth medical bench and so on2.primer,middle and HEPA filter ,sub-high efficiency filter3. undertake 100-300 thousand class level clean room design and construction of the project commission inspection and maintenance.ReceptionOfficeProduction Process   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
