It has been repeated many times online and in articles in every type of publication that we tend to not become fearful of things we can not see. And yet, the biggest challenge we have as humans is the transmission of airborne viruses that affect everyone multiple times in their lives. From the yearly Flu bug to Covid 19 and the Common Cold, all of these airborne viruses are constantly searching for a warm host to stay alive and grow.

For many of the airborne viruses there are anti-viral shots available to either eliminate your chances of getting it or minimizing the symptoms if you do get sick. For some reason, there are a number of groups ( all non-medical ) that constantly provide warnings about the various bad side affects of getting injections for all types of viruses. This has created a huge problem for the medical industry as more people are getting sick and in many cases requires them to be hospitalized. In many cases these anti-immunization groups even target mumps, measles and now polio. 

Yes, viruses are extremely small and not visible with the naked eye, but they can be and are significantly reduced or eliminated using filters such as HEPA and SULPA filters. These filters capture airborne viruses and are used in medical facilities around the world. Some of these HEPA systems are available to homeowners and small businesses here in the U.S. Since Covid, the increase use of these type of systems in commercial and institutional environments has doubled. However, with the public continuing to deny the value of anti-virual serems, the challenge to the public will continue to grow.

Pure Air Systems manufactures a line of HEPA and Carbon based, fan powered air filtration systems. These range in capacity from 50 CFM to 2000 CFM. These all metal units utilize the latest in variable speed motor and digital controllers to meet any application.

When Pure Air Systems was established in 1985, there were a number of companies selling HEPA like and HEPA type air filtration systems. Many of these were used in the Asbestos Abatement projects that were prevalent at that time. In fact, Pure Air Systems was a spin-off from HEPA unit designed for abatement but never got into production.

The model 600H unit was a unit with a prefilter, carbon media filter and true commercial grade HEPA filter with a 1/3HP GE motor and Lau Blower. It was in one large section which was subsequently broken into two sections. This was the beginning of the PAS Line of HEPA systems. 

As the popularity of the 600H unit grew, PAS introduced the new ECM motors from GE to make the HEPA system available as a stand alone unit as well as using variable speed motors that were then being introduced by all the HVAC companies.

By 1999 PAS had grown the line from one unit to seven different systems including the new portable unit. It has also moved into a new 9,000 square foot building. As of this date, 90% of the units are still built with parts made in the USA and it is now one of only 3 companies in the world that make this type of HEPA with the size and flexibility in size range and air flow control.

HEPA filters are the best method of removing sub-micron airborne contaminants including, viruses, bacteria, dust particles and airborne allergens ( mold, pollen, etc.).

One of the challenges of using HEPA filters in a residential application is how the HEPA filter is installed to best gather the greatest amount of airborne particles from all rooms of the home. Most air filters in residential HVAC systems are either placed in the air returns for each room or one largepr filter is placed at the return air inlet of the main HVAC fan unit. 

Since HEPA filters have a much higher resistance to air flow than standard duty air filters, they need to be placed in a cabinet that includes its own blower/motor section to assist the air flow through the HVAC system so there is no disruption to the air flow from the HVAC unit. 

Pure Air Systems developed a HEPA filtration system that incorporated its own blower/motor unit along with a true commercial grade HEPA filter, prefilter and carbon media filter. This metal framed housing unit could be attached to the return air side of the HVAC system in what is called a “partial pass” concept. In essence, the HEPA system would pull anywhere from 600 CFM up to 2000 CFM of the return air ( the later used mostly in commercial systems) and then return it back into the HVAC system on the supply side. In this manner the HEPA system would clean all the air in the house after the 3rd or 4th pass. Or, approximately 30 to 50 times  day, depending on how often the HVAC fan system runs.

The PAS units all utililze the newer variable speed drive, digitially controlled motors that can be programmed to operate in sync with any HVAC system.

If you live in a part of the country where the summer months bring high humidity along with the heat, then your indoor living environment needs adequate air conditioning to maintain healthy living. 

High amounts of humidity (moisture) will condense out on cold surfaces and can become a breading ground for mold. If the moisture gets into a crawl space or attic area that is not conditioned, this area can also be a potential place for mold to grow. 

Aside from efficient air conditioning, the home envelope should be under positive pressure. This means that when the HVAC system fan is running, the air pressure inside the home should be slightly higher than the external air pressure. This ensures the home will always be expelling a small amount of air and keeping outside moisture, heat and humidity from entering the home. If the home air balance is not correct, the negative affect of outside air intrusion into the home will far outweigh a good heating/cooling system.

In addition, good filtration should be part of your HVAC system. Whether you use good filters on the return air grills or a good media filter at the fan unit, filters can significantly minimize the levels of airborne dust and the potential for mold build up on interior surfaces.

Started in 1985, Pure Air Systems has been making commercial grade, fan-powered, true HEPA air filtration systems for over 38 years. The same high quality metal fabricated housings used then are still used today. High quality ECM motors and metal framed HEPA filters along with carbon media and ring panel prefilters are all part of the various systems offered by Pure Air Systems.

PAS makes units a number of systems ranging in air flow from 50 CFM up to 2000 CFM. These units are configured so they can be mounted either as stand-alone units or as part of an existing, ducted HVAC system. The powder coated painted 16 gauge steel housings can be mounted in side or outdoors depending upon the application.

The ECM motors provide for variable speed control using digital controllers or run by a computer system. In addition, they can be used in a a120 volt 60Hz electrical system or 240 volt 50 Hz system. This means they can be use in any location around the world.

HEPA filters are the best method of removing over 99.9995% of all particles 0.3 microns in size and larger and approach 99.99% for particles as small as 0.12 microns. They are used in all hospital and medical facilities and in commercial, military and residential markets.

Almost 80% of the products purchased on-line from Amazon, Walmart, Ebay and other web based stores, are manufactured in other countries. The majority being made in China. However, many of these products, including Apple iphones, etc, say they are designed in the US but made overseas.

Pure Air Systems has been designing and manufacturing their fan powered, commercial grade, HEPA air filtration systems since 1985. While some of the motors are now made overseas, over 90% of the components that make up the filtration system are made in the USA. These units have shown to be some of the best on the market and many of these systems are still in operation after over 20 years of service.

It is more expensive to purchase components and parts made in the USA and often times a wider selection of component and part types are available from outside the US. Manufacturing is a very challenging process and requires a lot of up front capital to obtain the machinery and skilled labor to make almost anything.

Pure Air Systems continues to look to the US companies to make any new components or parts that are needed for the existing and newly designed units. While these may be more expensive it is important to continue to use parts made in the US to keep these manufacturing operations viable.

Our eyes allow us to focus on and see airborne particles as small as 20 microns. For comparison, the human hair is about 100 microns in diameter. Most bacteria are in the range of less than 1 to 5 microns in size and viruses are less than 0.12 microns in size. So the old adage that what you don’t see won’t hurt you is not correct.

Bacteria, when present in a warm, moist environment, can stay alive for very long periods of time. From many hours to days. Because it is heavier than viruses it will not stay airborne for very long. So most contact with bacteria comes from contact with a surface or body part that caries the bacteria.

Viruses, on the other hand, are very tiny and light and can stay airborne for long period of time. This is how the flu and cold bugs are normally transmitted. Coming in a room or close contact where these viruses are airborne can infect another human once the viruses are inhaled and ingested. This is the reason masks are used in all medical facilities, especially surgical units.

For most home owners, having an air filter in the main return air duct next to the HVAC fan system or separate filters in the numerous return air outlets in the rooms of the house, constitute whole house air filtration. 99% of these filters are general duty filters that are capable of removing very large airborne particles and not adding any static pressure load to the HVAC fans. The compromise here is that you are trading air flow for not so good air filtration.

In 1985, Pure Air Systems introduced a new HEPA based, fan powered air filtration system that would provide a much higher level of removing much smaller airborne particulate including bateria and some viruses. By using a concept called, partial by-pass system, PAS can attach their HEPA units to the return air side of the HVAC ducting system and because the PAS systems have their own fan, they will not impede the performance of the main HVAC blower/motor assembly.  In addition, the PAS units also incorporate a prefilter and carbon media filter for removal of odors and gaseous pollutants. 

Since the inception of the partial by-pass concept, PAS has sold thousands of these units to home owners across North America and has even placed some on board ships and in the hospitality industry. This concept is easy to install and can be retrofitted on existing, ducted HVAC systems in any application.

Many products that used to be fabricated from metal are now made by using an injection molding process and a wide variety of plastics to keep the cost and weight down. In many cases this option works as the strength of many of the composite plastics are very strong and will work for most applications.

In 1985 Pure Air Systems began its process of making fan powered, commercial grade, HEPA air filtration systems for both the residential and commercial markets. The cabinets used to house the filter components was mild steel that was powder coated. These rugged housings allowed for the use in both interior and exterior applications and provided a housing structure that would last 20 years or longer under heavy use.

The housings ranged in size from the small portable which is approximately 13 inches square by 21 inches long, the 600HS series which is 16 inches square by 34 inches long ( high ), The 1200 HS series which is 25 inches square by 48 inches long and the 2000HS series which is identical to the 1200HS in size. All of these units are fabricated from 16 gauge powder coated steel and are built to last.

Early in the 90’s. Pure Air Systems looked at the possibility of using strong, composite plastic materials in-lieu of metal housings but found both the cost and challenge of making a unit strong enough to hold the metal blowers, ECM motors and HEPA filter and associated prefilter material. In this case, metal was and has always been the best choice for making the high performance HEPA based air filtration systems.

For the most part, human beings are fairly messy creatures…not being genetically that far apart from the animal kingdom as we know. Everyday we flake off millions of skin cells and spew out thousands of droplets of moisture every time we talk, laugh, cough or yell. This is how germs, bacteria and viruses are spread from person to person. Close contact just increases the chances of the exchange of body fluids.

Hospitals have the challenge of trying to keep their facilities as clean as possible due to the high rate of infections in hospital patients. Visitors coming into see their loved ones are one of the major players in the cause of infection, simply due to the fact that many patients are immunocompromised due to their post-operative state of health. This is why all the operating rooms are pressurized with 100% HEPA filtered air….to minimize or remove the possibility of bacteria or viruses from entering the surgery suite while the patient is under the knife.

Pure Air Systems has been making fan powered, commercial grade, HEPA filtration systems since 1985 and is considered one of the leaders in this specialized industry. These systems range in air volume from 50 CFM up to 2,000 CFM using variable speed motors for finite volume control to suit any application. PAS makes 7 different models that can be used as stand-alone units or in conjunction with a ducted HVAC system. All of the PAS models are fabricated from galvanized steel and are powder coated for a high end finish. 

Each filter unit comes complete with a prefilter, carbon media filter and true, scanned 99.99% HEPA filter. The motors are all variable speed, programmable and offer 120/240 Volt, 50/60Hz operation for locations anywhere in the world.
