For most individuals the ability to breathe is so automatic we almost never even think about the process. Only when we are subjected to a high amount of airborne dust or particulate or near smoke do we find it somewhat difficult to breathe.
For people who suffer from Asthma or other respiratory dysfunctions the ability to breathe normally is not taken for granted. They are very aware that at anytime they may suffer from an Asthma attack or their ability to breathe due to either their illness, airborne particulate or both.
Pure Air Systems has been manufacturing commercial grade HEPA based air filtration systems since 1985. These fan powered units are designed to work in concert with any type of HVAC system or as stand-alone units. And, these systems utilize the ECM variable speed drive motors so air volume control can be finite and they can be used anywhere in the world.
The PAS units can be attached to almost any home HVAC unit and provide a very high degree of airborne particulate removal of the size of the particulate that affects those individuals with respiratory dysfunctions.
The HEPA filters used in the line of systems offered by Pure Air Systems are called scanned HEPA filters. These filters have an initial efficiency of 99.99% at 0.3 microns and become more efficiency as they begin to collect the particulate. You can see a 20 micron sized particle with the naked eye and these particles are normally aspirated in and then expelled easily. The smaller particles, those less than 10 microns in size are easily trapped in the mucus membranes of the lungs and can cause irritation. These are the particles that create real health issues for those who suffer from Asthma.
