The filters we are describing here, like our military, will help to ensure your  freedom from unwanted and hard to see enemies. Except in this case we are talking about sub-micron airborne particles. These enemies  are well known by people  who suffer from allergies caused by airborne particles inside or out doors.

With something as aggressive as airborne allergens it would seem that we should be able to actually see them in the air so we could  evade their presence in some fashion. But that is not so. While some of these airborne particles are large enough to see when then collect on the surface of your table or clothing, they are too small ( less than 20 microns in size ) to see when they are floating around your head.

Standard general duty media filters, like the ones you use  in your furnace, are good for removing large particles, those that usually fall to the ground or are easily trapped by your mucus membranes then expelled out again, are not the ones that are harmful. It is those particles that are 10 microns or less that are more easily trapped in our lungs and  create the irritations  that become the allergic reaction that you makes you miserable for weeks and months at a time.

Pure Air Systems began to market their HEPA based air filtration systems in 1985 and today is one of the major suppliers of true, commercial grade, HEPA based, fan powered, high performance, air filtration systems on the market today. Their systems are designed to be used as either stand-alone or in partial by-pass with existing ducted  HVAC systems. These units are powerful built to perform for years with minimal maintenance and only simple filter replacements are needed on scheduled frequencies.

HEPA filters will remove 99.99% of all particles 0.3 microns or larger and approach almost that same efficiency for particles as small as .012 microns. These systems, when properly installed in a home or commercial building, will significantly reduce the amount of respirable sized harmful airborne particles where a real reduction in allergies and respiratory problems is demonstrated.
