AllerAir A5FSH948 Super HEPA Filter – 99.99% at 0.1 Micron

A5FSH948 Super HEPA replacement filter The A5FSH948 is the particle stage for the AllerAir AirMedic Pro 5 HD and AllerAir AirMedic Pro 5 Ultra. AllerAir rates it at 99.99% of airborne particles at 0.1 micron. Standard HEPA is rated 99.97% at 0.3 micron, so the Super HEPA is specified at a tighter efficiency and at a smaller test particle. How is Super HEPA rated against standard HEPA? The two ratings use different test particle sizes, so they are not directly interchangeable numbers. Both media capture the coarse fraction — dust, pollen, dander, mould spores. Super HEPA is the grade AllerAir specifies for severe allergy, asthma and chemically sensitive rooms. Where it earns its place 99.99% at 0.1 micron — AllerAir's rated efficiency for this media Smoke and fine particulate — AllerAir lists smoke and fine particulate matter (PM2.5) among what it captures Works with the carbon stage — particles here, gases and odours there; neither replaces the other Service notes AllerAir recommends replacing the Super HEPA every 12 months, sooner in heavy dust, smoke or pollution.
