HEPA For Terrorism

We are constantly reminded that we live in a era where anyone at anytime can create mayhem with simple, exotic or well crafted killing tools. There are no limits as to what device a motivated anarchist can do with any of these style devices. Yet, for all the external damage that can be done with hard technology, the invisible, airborne pathogen still creates the greatest threat.

Tiny viruses and bacteria are invisible to the naked eye but can be a major threat to our bodies if these pathogens are inhaled, absorbed or injected into our systems. The only true method of totally removing these objects is to use a mechanical filter such as HEPA. High Efficiency Particulate Air filters have been around since 1940 but their real push into the market came in the late 70’s and early 80’s with the development of the micro-chip.

As HEPA technology improved the types of HEPA paper and testing methods became more effective especially as organizations like the CDC began to work with some really horrible contagions and had to isolate them in special rooms with multiple levels of HEPA filters including the newer ULPA (Ultra Low Particulate Air ) and the new SULPA (Super Ultra Low Particulate Air) filters.

In 1985, Pure Air Systems came onto the market offering true, commercial grade, fan-powered HEPA air filtration systems. This was the first true entry of commercial grade HEPA units into the residential market place. Over the years a total of 7 HEPA systems were produced by PAS and the incorporation of the new ECM motors allowed them to create models that had variable speed motors and that could be sold anywhere in the world.

These systems are considered some of the best HEPA filtration systems in the world and have been used in applications where the facility is being prepared to protect against biological attacks. There is no better filter for removal of harmful airborne pathogens than HEPA.

Creating Negative Pressure With HEPA Filtration Systems

Pure Air Systems started making HEPA based air filtration systems in 1985. Today they are one of the leaders in HEPA filter technology with over 7 different fan powered systems ranging in capacity from 50 CFM to 2,000 CFM.

In the 60’s and 70’s Asbestos removal was a very big industry as older homes and builders were gutted to remove the harmful asbestos materials. In order to keep the asbestos fibers from flying around and getting out into the open areas or outside the contaminated space, the areas being cleaned up were enclosed in 3 millimeter thick Polyethylene sheeting. Large, fan powered HEPA systems were placed outside the containment area pulling air from inside the containment area creating a negative pressure inside the cleaning zone.

The HEPA filters would trap any of the Asbestos particles and when you entered the containment area through a zipped door air would move into the zone rather than come out of the zoned area.

In the medical field when patients are considered to have a highly communicable disease, they are often placed in rooms that are kept under negative pressure again using fan powered HEPA filter systems. This ensures that any viruses in the room stay in the room.

These same techniques are used by the CDC or WHO when they are working with deadly viruses and bacteria. The rooms where they experiment with these pathogens are tightly sealed and under negative pressure with the air passing through multiple layers of HEPA filters using HEPA, ULPA and SULPA filters. The rooms are designed so that the doors will not open unless the air handlers and HEPA systems are in operation.

HEPA filters are made from very dense media and they have a lot of resistance so larger motor /blower units are required to move air through the HEPA filters. HEPA filters are the only filters capable of removing particles as small as 0.12 microns at levels approaching 99.99995%.

Hey!…Let Me Share My Germs With You!

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.
