Indoor Air Quality has been an issue for enclosed spaces, homes, office buildings, medical facilities and industrial buildings since the early 70’s. The issues of people suffering from a wide range of health issues, mostly respiratory in nature, became more acute once the building industry started to build tighter buildings that offered little or no outside air intrusion. This process reduced the energy costs, but increased the amount of stale air and concentrations of gaseous pollutants and airborne particulate that are generated from most materials, chemicals, plants, animals and manufacturing processes.

Using only recirculating air through the air handlers and HVAC units and not allowing any outside, fresh air increased the IAQ issues. Adding outside air only added to the amount of particulate already present in the occupied space.

Pure Air Systems, based in Indiana, had developed a variety of commercial grade, fan powered, HEPA filter systems that could be used to both filter the air in the space as well as add small amounts of filtered outside air. By only adding 50 CMF to 100 CFM of outside air through the PAS units, one air handler could introduce up to 6,000 CFM of fresh, filtered outside air every hour and adding that to the recirculated air also being filtered, created a much healthier environment and reduced the amount of headaches, and respiratory issues in most residential and commercial operations.

Adding the small amounts of outside air, even on hot and very cold days, had a minimal affect on the amount of energy required to heat and cool the indoor environment. By adding an actuator to the inlet damper, it is possible to modulate the amount of outside air so that more or less air could be introduced depending upon weather or the conditions in the occupied space.

Founded in 1985, Pure Air Systems was one of the first companies to introduce true, commercial grade, fan powered HEPA air filtration systems. The first unit, model 600H, was the base model using a standard 120 volt, 60Hz GE motor, Lau blowers, scanned HEPA filters, carbon media packs and ring panel pre-filters and switches and wire harnesses. All American made. 

Today, Pure Air Systems has 5 different models ranging from 50 CFM to 2000 CFM using the same metal housings, HEPA filters, carbon media packs but with the new variable speed 120/240 volt 50/60HZ motors, digital controllers and pressure gauges. Again, all of these components are currently being made in the USA. In addition, PAS is now one of only three companies in the world that manufacture these commercial grade HEPA air filtration systems.

Making products using US made components in today’s world creates some unusual issues. With most companies using components made in China or other overseas countries, competing with US made components is becoming more difficult. However, the Pure Air Systems units historically have a 15 to 20 year life cycle even in heavy duty operations. The cost may be higher but the performance is unmatched when comparing to similar products made in China.

Smoke from cigarettes and cigars is highly visible and has a distinct odor. It is pungent and will stick to any surface and re-release the odor for a long time. It will cling to clothing and stain hard surfaces over time. Of all the airborne contaminants we generate, cigarette smoke is the most difficult to remove from the air.

Smoke from cigarettes and cigars has both a particulate component and an odor component. Both difficult to capture using filtration systems. The odor can only be removed using carbon based media and the cigarette smoke will even plug up a HEPA filter over time.

The use of ozone generators or UV lights also do very little to alleviate this situation indoors and it is now  the reason smoking is prohibited in almost all indoor facilities, restaurants and eating establishments. It is just too difficult to mitigate with almost any filtration technology.

Pure Air Systems has been making high end, HEPA based, fan powered air filtration systems since 1985 and one of only three companies in the world that make systems for both the commercial and residential markets. The systems range in capacity from 50 DFM to 2000 CFM and can include a prefilter, scanned HEPA filter and carbon media. The systems now all use variable speed drive motors and are digitally controlled. The units are also capable of being used in 120/240 50/60hz applications.

For the majority of the U.S., Summer represents hot days, hot nights and in many parts of the U.S., high humidity. This means that for the most part people will remain indoors in their homes, offices and shopping areas in the presence of cool, air conditioning. 

While air conditioning keeps the interior space cool and removes the majority of the humidity, the lack of any outside fresh air means that all the air in the home, office, school or shopping areas is stagnant or stale. Without any type of effective air filtration, the levels of airborne particles (which can include, human skin, bug matter, airborne dust and debris of all types) will increase 10 fold. And, if there are animals present, then the potential for high concentrations of animal dander may occur.

In order to minimize the health hazards of breathing stale, polluted indoor air for long periods of time, we recommend using good air filters on your returns or consider putting one of our 600HS Plus HEPA systems on your ducted forced air HFAC system. With the unique partial-bypass installation concept it is possible to filter all the air in your house up to 24 times per day and introduce a small amount of outside, filtered fresh air without upsetting the AC temperature and humidity in your home.

Intel is investing $20 Billion dollars to build two state-of-the-art Micro Chip manufacturing plants in Albany, Ohio. Chip manufacturing is done in Class 10 and Class 100 clean room facilities which are constantly being cleaned by HEPA filters with the rooms being under positive air pressure.

Chips are comprised of multiple layers and then assembled together. These layers are highly sensitive to any airborne particulate, even in the sub-micron level, as the dust particle will destroy the chips function and short it out when in use. The types of HEPA filters used in the manufacturing and assembly areas are normally comprised of a series of HEPA’s in banks. They use HEPA, ULPA and SULPA HEPA filters that will remove 99.9999% of all particles 0.12 microns and smaller. As as comparison, the Human hair is about 100 microns in diameter.

Pure Air Systems has been providing commercial grade, fan powered, scanned HEPA filters ( 99.99% at 0.3 microns) since 1985. Many of these systems have been and are being used in smaller micro chip operations, medical facilities, hospitals, military and institutional plants. The PAS systems range from 50 CFM up to 2000 CFM and can include Carbon media along with a Prefilter.

The removal of gaseous pollutants ( odors ) is often accomplished by using a masking agent sprayed into the room or area with the odor. If the odor is temporary or infrequent then the aerosol spray deodorizers will usually meet the task. If, however, the odor is from a continuous source and is strong enough or dangerous to breathe then commercial grade carbon media filters will be required.

The use of expanded carbon ( charcoal) for the reduction/removal of airborne gaseous pollutants has been around for over 100 years. These carbon media packs ( usually 1 inch to 4 inches in depth) can be very effective at removing these strong, continuous odors and the carbon can be combined with other materials to catalyze some pollutants that are not removed by just carbon alone.

Pure Air Systems, has been manufacturing HEPA and Carbon based, fan powered, commercial grade air filtration systems, since 1985. These metal framed units incorporate the newer variable speed motors and the air flows range from a low of 50 CFM up to 2,000 CFM. PAS offers a wide range of sizes and configurations to fit any specific need. Some of the large units can hold up to 80 lbs of carbon media or applications where high concentrations of gaseous pollutants are present.

The issue regarding masks and their effectiveness has been a constant battle in this country. Facts of how masks work and their value have been bashed by the uneducated and anti-vax groups for the past year with no viable, technical data to support their claims. N95 Style masks do provide some viable protection against sub-micron sized particles.

Pure Air Systems has been making HEPA based air filtration systems since 1985 and has over 36 years of experience in dealing with airborne allergens and pathogens. HEPA filters are used extensively in the CDC and pharmaceutical companies around the world. The N95 masks have similar particle reduction capabilities and are very affective in keeping the wearer safe from airborne viruses and bacteria.

For some strange reason people want to discount the science of air filtration in lieu-of nonsense spewed by the social media pawns. It is important that the general public do their own research and not listen to the TV pundits who are only trying to get their ratings up for their sponsors and are not interested in providing reliable information to the public.

Covid and its new strains will be with us for a long time and the more we debate the value of the masks the longer we put off making these mask issues a useful and necessary part of daily life the longer we will deal with the virus.

The Chevy Nova was made in the early 60’s through part of the 70’s and was somewhat popular as a mid sized, low cost vehicle. This car also had many mechanical issues and was dropped from the line up only to be resurrected as the Chevy Citation in the 80’s. Different design, same issues. When the Japanese entered the US car market they were surprised that General Motors ad chosen the name Nova because in Japanese this word means NO GO. This should have been a warning to GM not to use that name.

When Pure Air Systems came out with their HEPA filtration systems in 1985, the units were considered too expensive and the existing furnace type media filters were considered the best filters on the market. Ozone generators and Ion Generators were also sold as high efficiency air filter systems and were much less expensive than the HEPA units. However, like the Nova, these general duty air filtration filters and mechanical systems did not work as promised and are still sold today to unsuspecting consumers. 

The fan powered, commercial grade HEPA filtration systems by PAS are considered some of the best overall HEPA systems on the market. And, Pure Air Systems, Inc. is one of only 3 companies in the world that make this type of HEPA system with a wide range of sizes and housing configurations. The PAS line offers systems that range from 50 CFM to 2000 CFM using new ECM variable speed drive motors.

There are some songs that seem to transcend time and this one by Eric Burton and the Animals is not exception. For almost anyone alive today hearing the first 5 cords of this song instantly remind you of what comes next. There are products and companies that also fall into this category.

Pure Air Systems, Inc. Founded in 1985, is one of those companies. PAS was one of the first companies in North America to offer true HEPA based, fan powered, air filtration systems for both residential and commercial applications. The model 600HS was the first HEPA system that was designed to attach to any forced air, ducted HVAC system using the partial by-pass concept. This allowed the use of the 600, 1200 and 2000HS series units to used in any application for any size HVAC unit with the added ability to introduced fresh, filtered outside air in small quantities to help pressurize any environment.

Today, Pure Air Systems is one of only 3 companies in the world that produce this type of commercial grade HEPA air filtration system. These units also use the variable speed drive motors and can be programmed to adjust the speed ( air flow in CFM ) to suit the application.

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.
