You’re standing in a crowded train or bus or airport and you are shoulder to shoulder with the other people and you notice that someone close to you is sneezing or blowing their nose or coughing. Your first thought is….I wonder if that individual just expelled some unwanted germs in my direction. You cover your mouth and nose hoping your hand will ward off any unwanted airborne allergens or pathogens and realize that anything less than a full face mask with a HEPA filter is useless.
Okay, so let’s take this same example and look at it in the place where the little people and all their germs reside….School. Specifically pre-school. This is the place where children come with their runny noses, colds, allergies and a litany of communicable diseases. The children are always in close proximity to each other. They wrestle with each other, sit next to each other and share their food or snacks, which could be considered a petri dish of germs. If you have a young child that is placed in this environment you now know why they often have colds or cold like symptoms.
Pure Air Systems has bee making HEPA and Carbon based air filtration systems for the residential, commercial, institutional and industrial markets since 1985. Their fan powered HEPA based units are used throughout North America, Europe, Asia and Africa. These systems can either be used attached to an existing HVAC system or as stand-alone units.
There are a number of pre-Schools and elementary schools that now employ these units in their facilities to minimize the spread of airborne pathogens and allergens. Some of these facilities use the larger HEPA systems that attach to the existing heating/cooling ductwork systems and filter all the air being pulled into the return air side of the HVAC unit and push out HEPA filtered air. In this manner the air in the school rooms is being filtered up to 48 times a day.
In some applications the PAS HEPA systems are used as stand alone units where they are placed in or in close proximity to the rooms and filter the air at much higher rates. In either case, the results of using these PAS HEPA units in the schools has shown a marked decrease in the amount of colds, runny noses and missed school days due to illness. Also, many of these schools promote the use of these systems to assist them in bringing in more business by extolling the “health” benefits of placing their children in there particular facility.
