Pure Air Systems began its journey in 1985 producing one of the first true, commercial grade, fan powered air filtration system that could be used in either commercial or residential applications. These units were made from 20 gauge mild steel that is powder coated for a durable, long-lasting finish. 

Today, the line up of 7 different systems made in variations in both size and air flow design are still made from the same high-grade 20 gauge powder coated steel housings now using the latest iteration of the variable speed drive motors that are digitally controlled. The HEPA filters are all 99.99% efficient at .3 microns and larger and the prefilters and carbon filters come standard with each unit. 

The HEPA Shield systems come in air flow ranges from a low of 50 CFM from our portable unit up to 2,000 CFM on our largest model 2000HS unit. These systems can also be modified to be attached to an existing HVAC duct work system or as stand-alone units. 

Pure Air Systems are all made here in the USA with most of the components manufactured in the US. Some of the original units are still in operation and the average longevity of any of the systems is better than 15 years. Making the PAS units one of the best economical purchases for any air filtration system on the market today.

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.

3D Printing or Additive Manufacturing as it is called in the commercial market, has moved into almost every facet of manufacturing from small replacement parts and dental fittings up to Aerospace and Military applications. There are very large 3D printers making boats as well as printing houses and large structures and small bridges.

3D printing has a number of advantages including the ability to try the “what if” and prototyping of new design concepts. In addition, the materials available for the metal printers has moved this process in the main stream of manufacturing. 3D Printers take up much less space than traditional CNC machines and other fabrication systems and require fewer people to complete the manufacturing process.

One of the main advantages of using 3D manufacturing is the ability to get younger people to become more involved with manufacturing. The younger generation is very familiar with and is good at using CAD type software for design and 3D printing of parts. In truth, the ability to make things using 3D printing or Additive Manufacturing is not considered manufacturing to the younger generation. This is important as they are not interested in moving into the old type of making things. 

Pure Air Systems, an air filtration company started in 1985, has bee using some 3D printing processes for prototyping new parts for their metal housed HEPA based air filtration systems. This helps them more quickly determine the correct part design and more quickly complete the final design and get into production with minimal cost.

The Covid issue has been dissected by everyone in every discipline including social media. The fact remains that Covid is virus and like all other viruses it is extremely small ( less than .012 microns in size ) and easily transmitted through the air. While the various types of face masks that are available are not truly capable of removing 100% of the airborne viruses, they can significantly minimize the levels of virus ingestion. 

In 1985 Pure Air Systems introduced an air filtration system utilizing true, commercial grade HEPA filters for the residential and commercial markets. These fan powered systems are capable of either being attached to existing HVAC systems or stand-alone. 

HEPA filters are used in all hospital surgery suites, laboratories, pharmaceutical companies, chip manufacturing and more. These filters are specially designed to remove airborne particles as small as viruses and are extremely efficient over their life. The type of filter media used in the HEPA filters is partially copied in some of the new face masks now on the market. Then N95 mask is one of them.

It is important to know that the viruses that are now out in the world are extremely capable of changing and adapting to new drugs and pharmaceuticals, therefore making them around as long as we inhabit this planet.

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.

Covid-19 has reignited the air filtration market with new ( old technology ) being offered to the public as the panacea for removing viruses from the air. Unfortunately, these old technologies are being regurgitated as the panacea for keeping you safe from airborne viruses such as Covid-19, et al.  UV lights are good for illuminating finger prints on glass if you are a forensic scientist searching for a perpetrator but this light does very little to destroy airborne bacteria and viruses. For UV light to have any affect on airborne contaminants, the particles need to be exposed for a long period of time ( from 1 to 10 minutes). Since most UV lights are installed in HVAC systems the speed of the air passing by the UV light somewhat defeats the purpose of using the light in the first place.

Ozone Generators have been around for more than 40 years and were used originally to reduce odors in commercial applications. Ozone is made up of 3 Oxygen molecules and will easily give up one of its molecules when it comes in contact with another gaseous molecule and changes the chemical nature of that molecule. This is how it reduces odors by simply changing the chemical nature of the odor producing molecule. Ozone also attacks carbon based objects and humans are basically carbon based forms. For airborne particulate, Ozone is not effective as it does not have any capture mechanisms to reduce the level of the particulate. Again, particulte would have to be in contact with the Ozone for long periods of time to have any affect at all.

Mechanical air filters, which include all media air filters including HEPA filters, are the only mechanism available to remove and capture airborne bacteria and viruses. This is why all Hospitals, clinics, laboratories and other medical facilities use HEPA or HEPA type filters to protect the occupants from viruses such as Covid-19. Even the lesser efficient air filters that are used in homes and offices that  have some minimal effect on removing viruses are better that using UV lights and Ozone generators.

Created in 1985, Pure Air Systems was one of the first US companies to offer commercial grade, fan powered, HEPA air filtration systems for the general publc. These systems are designed to be used as both stand-alone units as well as attaching them to existing HVAC systems to provide central and whole house filtration. Over the next 10 years Pure Air Systems developed seven different sizes and configurations varying in air volume capacity from 50 CFM to 2,000 CFM. In addition the systems had the capacity to add carbon media and prefiltration in conjunction with the HEPA filters providing systems that could handle almost any air filtration or odor challenge in the market.

When Covid-19 entered the globe in eary 2020, many of the hospitals, clinics, laboratories and municipal facilities across Norht America started lookng for HEPA based air filtration systems as HEPA filters are the only type of air filter that can remove a subtantial amounty of airborne viruses. Standard air filters are, for the most part, not very effective in removing these sub-micron particulate from the air. 

The Pure Air Systems units use very powerful, variable speed drive motors ranging from 1/3 HP to 1 HP, they can move a lot of air through the HEPA filters which are extremely dense. In additon, the units can move air through ductwork that is connected to the filtration systems so they can be used to provide clean air in a large space. The systems can also be used to create either a positive or negative room area for patient isolation as is the common practice in most Hospitals.

Today, Pure Air Systems is one of only three companies around the world that produces a metal framed, commercial grade, fan powered true HEPA air filtration that can be used in a very wide range of applications in the residential, commercial, institutional, industrial and medical markets.

Most people are familiar with the air filters that go into your HVAC system that look like folded or pleated paper media. These are normally refered to as mechanical filters because they use the mechanics of air velocity to impinge the airborne particulater onto the surface of the filter. Electronic air filters use positive – negative charging as their method of collecting these same particles. These electronic air cleaners use plates for wire grids to trap the particles but unlike mechanical filters, are less efficient than mechanical air filters as they allow for much of the particulate to pass by the collection grids without capture. For this reason mechancial air filters are the preferred method of dust collection.

Air filters perform two major functions in HVAC systems. One is to keep the dust from accumulating on the cooling coils in your air handler to ensure proper performance of you air conditioning system. The second is the removal of airborne particulate in the air to keep the indoor environment cleaner. These mechanical air filters come in different efficiencies from general duty up the high efficiency HEPA air filters.

The use of very high efficiency mechanical filters including HEPA sysems is now extremely important due to the need to remove airborne bacteria and viruses during this pandemic. Schools, office buildings, and all medical faciities are using mechanical air filters with higher efficiency ratings to contain the airbone contaminents as much as possible.

Ultra Violet lights (germicidal lamps) or UV systems come in both a hot (8,000 hours life) and cold plasma (rate 36,000 hours life) lamp systems. They produce a specific wavelength of 253 nanometers and produce UV C. This wavelength has the ability to affect microbiological contaminants like mold and bacteria. The UV C light can destroy the DNA of the microbiological and keep it from replicating. UV C has no effect on solid particles and it does NOT remove anything from the air stream. UV C lights are normally placed in the return air stream, although the speed of the air past the lights can minimize the effectiveness of the UV lights. We suggest that placing a UV light at or near the cooling coils works better as the light can irradiate this moist area all the time and help in minimizing the growth of mold or bacteria. UV lights are an ancillary piece of equipment and should always be used in conjunction with an air filter or air filtration system.

The Use of UV lights to reduce or kill Covid 19 viruses is somewhat limited to the distance to and the duration of time it sees the virus. That is why UV lights are more effective placed in the return air duct of the HVAC system and the fan has to be running all the time. Further more, you need really good filtration in front of the UV lights otherwise they will become coated with dirt and dust and thus significantly reduce their effectiveness.

If you look at the miriad of photos and TV footage of Hospital wards treating Covid 19 patients, you never see any UV lights in and around the patient beds. Sterilaztion with chemicals and the use of PPE are much more effective in that area of the hospital. The real danger in using UV lights is the thought that this technology is a primary method of eliminating the Covid virus when in truth it is  only a terciary device at best.

Pure Air Systems has been making HEPA based air filtration systems for over 35 years and today the use of HEPA filters has become the primary method of maintaining surgery room cleanliness in Hosptials, Clinics and laboratories all working with Covid. 19.

SInce man first walked on the earth he has been finding ways to make life easier, safer and more productive. His inate drive to explore and learn are bult into his DNA. It is a survival of the fitest condition. Everything we use and have at our disposal was invented by man ( or woman ). The balance is deliverd by Mother Nature, which is, in many ways, more powerful and more important. . Some of those things Mother Nature delivers include diseases that are benign to animals but cause significant challenges to man. In some cases man’s own drive creates the conditions by which these diseases become deadly. 

Covid-19 is science. It is biological science and it plays with our DNA. As a virus it follows the same drive as man..survival of the fitest. It will do whatever it takes to keep growing and moving as it jumps from human host to human host.It really doesn’t have a conscience or any political aspirations and is not threatened by any medicine was currently have at our disposal. It will command our attention for a very long time. It is a variant of science so obviously it will require science to tame it. Man has the ability to resolve this issue if it is taken seriously. If not, then perhaps we should paraphrase the words in Matthew 5 where he says ‘ and the meek shall inherit the earth.”
