Pure Air Systems Shares Rarified Air

Created in 1985 by Don Musilli, Pure Air Systems was one of many companies offering air filtration systems for the commercial and residential markets. But the separation from the competition began shortly thereafter. From the beginning, PAS used an all metal housings, Lau Blowers, GE Motors and commercial grade prefiters, carbon media and HEPA filters. The initial units sold for $695.00. Over time, PAS added other units to their line up and in 1998 became one of the first powered fan filter companies to use the new GE ECM variable speed drive motors. 

The addition of the new motors and expansion to a 9,000 sq. ft. building allowed PAS to expand their product line to 7 different size air filtration systems all of them now using the upgraded, digitally controlled variable speed drive motors. The ability for the motors to be 120/240 50/60 Hz created a new market overseas for the larger systems. The new HPS portable unit opened the doors to more medical markets and the Covid – 19 global pandemic created a whole new market for commercial grade HEPA air filtration systems.

Today, there are only two other companies in the world that make a fan powered, commercial grade HEPA air filtration unit handling up to 2,000 CFM and as low as 50 CFM. With material costs for metal and other components increasing rapidly, it is much more difficult for companies to offer products such as the ones from Pure Air Systems.

High Performance HEPA Portable By Pure Air Systems

Pure Air Systems has been making commercial grade, fan powered HEPA air filtration systems since 1985. They are one of three companies in the world that provide this type of filtration systems. PAS makes a number of models of HEPA systems that range from 600 CFM to 2000 CFM all using variable speed drive motors. Their portable system, the HPS series was introduced around 1992 and has since gone through a number of refinements. It was the only HEPA unit in the line-up that did not use a variable speed drive motor. In stead, it used a 4 speed motor from EBM. 

Coming this year, PAS will be fitting the popular portable HPS unit wiith it’s own variable speed drive motor. This will allow for a CFM range from 25 CFM up to 250 CFM in 1% increments. In addition, the new motor will be designed to maintain the same speed/cfm rating even as the pressure drop increses across the HEPA filter.And likes the original version, the new HPS unit will have a prefilter,carbon filter and a true 99.99% scanned HEPA fitler as standard equipment.

The portable HEPA unit has a wide range of applications and is very well suited fror the laboratory environment as well as small confined areas requiring HEPA filtraiton in both a positive or negative room application. The all metal housing and rugged construction make this one of the best portable HEPA systems on the global market.

Portable HEPA Filter Systems For Any Application

There are many commercial and institutional applications where a true HEPA filtration system is required but space and time of need is limited. Pure Air Systems, based in Indianapolis, manufactures a complete line of HEPA and Carbon based, fan powered air filtration systems that range in air flow capacity from 50 CFM to 2,000 CFM. These systems use high end blowers and motors and are framed in all metal housings.

The HPS model portable units from Pure Air Systems have a four speed motor/blower, a ring panel prefilter/carbon media filter and a true, scanned HEPA rated at 99.99% at 0.3 microns and larger. These portable units are 13″ square by 24″ long and weigh only 34 lbs. These units are very powerful and can move up to 250 CFM of HEPA filtered air. While these units are often used in small laboratories, hospital rooms, nursing homes, clinics and mobile trailers, they are a perfect filtration system for the home and office. 

The powerful fans allow you to use this system either as a stand-alone system or attached to duct work so they can move air through a fairly large area and can also be used to provide positive or negative air pressure in any enclosed space. The PAS HPS series are the most powerful portable HEPA units on the market today and the average length of time in service of 15 years.

Pure Air Systems also offers a complete line of HEPA based systems that are designed with unique configurations so that you can install a unit in any location with the ability to have the inlet and discharge in any direction for best installation and performance. PAS offers 7 different orientations for all of its systems with the exception of the portable unit.

When magicians place a person in a box, cover the box, then pull the cover away within seconds and the person is gone, this trick is often referred to as misdirection or sometimes called slight of hand. In either case the idea is to get you to look one way while the action is actually taking place somewhere else. Simple, effective and easily done by trained entertainers who couch themselves as Magicians.

Misdirection was, and in many cases still is, used often in the early 30’s and 40’s when a peddler selling a product would demonstrate the operation and value of the item to the audience. When you purchased the item, always packed in a box, took it home it often didn’t work or would not perform at the same level as described by the salesmen. When you went to return the item the seller was often no where to be seen. Even today with the “As Seen On TV” products flood the dollar stores and discount houses, the products often fail to meet the perceived expectations.

The technicians at Pure Air Systems have been manufacturing commercial grade, certified, fan powered HEPA based air filtration systems  since 1985. From the beginning the systems produced by PAS always met or exceeded the performance expectations of their customers. The PAS systems are a more expensive product than some of the other non-HEPA based filtration, air purification and electronic air cleaners currently on the market. Unfortunately many of these “lesser performing devices” claim to provide the same particle reduction capabilities as HEPA filters, but at a lower cost.

Often times a new Pure Air Systems customer will try one, two or more alternate “air filtration/purification” devices before they actually purchase one of the seven different HEPA models offered by PAS. The other “HEPA Type” or “HEPA Like” companies provide inaccurate information as to the overall ability of their products to remove and/or reduce the levels of harmful airborne particulates and contaminants. But because the systems are less expensive individuals will buy the hype only to find their is truth in the statement, “you get what you pay for.”

This is not to say that other types of filtration and purification systems are effective. But for those companies, institutions and medical operations that require initial efficiency’s of 99.99% at 0.3 microns or larger, then the only option they have is to use the HEPA based systems by Pure Air Systems. Don’t be fooled by the imitators.

Shark Dive

As an avid Scuba Diver I have had the privilege of diving in some of the most beautiful places on earth and in some of the best, most pristine dive sites. The under sea world is vastly different than what is above the surface. A much more serene environment that has a wide array of colors, creatures and coral formations that are not duplicated anywhere on land. When I talk to people who have never snorkeled or dove one of their first comments is how concerned am I in diving in the same oceans where there are Sharks.

There is a lot of misconception about diving with Sharks.I have done numerous dives with Sharks and occasionally run into some on many dive trips. Sharks and Divers get a long very well, contrary to what many people may believe.  Just because these creatures are aggressive animals when hunting in their natural environment doesn’t mean they are natural enemies of man. They are not. There is a mutual respect among man and these predators.

Often times in business we have the perception that a particular company, businessman or woman has taken an aggressive position in building their company. The use of acquisitions, mergers, pricing under the competition and hiring employees away from other firms is often looked at with contempt. Like the Shark who is often considered being the ruler of the deep, these dominant organizations are often viewed as predators.

In today’s “adapt-or-die” business environment, it is very difficult to not be viewed as an aggressor when the ability to succeed or fail depends upon your ability to battle with the rest of the Shark’s in the water. Even with patents and exclusive rights for properties and technology, it is becoming harder to differentiate your product from the competition.  So sometimes you have to resort to eating your competition…so to speak.

Pure Air Systems has been making HEPA and Carbon based, fan powered air filtration systems since 1985. To survive in this vastly competitive market, PAS had to continuously re-invent itself and develop new products and got after larger markets in order to continue to grow. Starting from one system, PAS now has a very extensive line of commercial grade, certified HEPA based air filtration systems that are sold throughout the world. These units all use the newer ECM variable speed 120/240 volt, 50/60Hz digitally controlled motors and are capable of producing from 40 CFM up to 2,000 CFM of HEPA filtered air.

Pure Air Systems originally started selling their systems primarily for residential use. It was soon discovered that many small businesses, especially in the medical and high-tech sectors, needed commercial grade HEPA systems to maintain levels of airborne sub-micron particulate down to levels that could not be achieved with standard air filters. This usage lead to developing even larger systems and the addition of a brand new portable unit.

Today, Pure Air Systems is one of the leaders in high capacity, variable speed drive HEPA based air filtration systems for the commercial, institutional, medical, industrial and residential markets.

Coastal Differences

The differences between the east and west coast are significant. The only similarity is the comparison between LA/SF and New York City. All three of these cities are considered the ultimate destinations and take pride in being the more avant garde of all the cities in the US. New technologies and innovation seem to come more from the West coast than the east coast, however, the Midwest continues to be the major supplier of manufactured goods and  machinery.

This differences are not only based on the company styles and culture but the differences in the demographics as well. The younger, under 45 crowd tends to be the major population base in many parts of California, Oregon and Washington. Although places like Austin, Texas also revel in commanding the young professionals and entrepreneurs. New York has a broad mixture but still a large percentage of those in the greater New York City area are the new “whatever letter they call them” generation. In either coast, the manufacturing of new products seems to be usurped by the development of digital software, apps and enterprise systems. While many of these products have proven to be valuable to our marketing and social media infrastructure, they don’t come close in monetary or job creation like hard technologies.

Pure Air Systems has been manufacturing certified, commercial grade HEPA air filtration systems since 1985. Their roots are in the Midwest where manufacturing had and still has its base. The ability to develop these high end units using state-of-the-art ECM motors and electrical components was made easier by being closer to the geographical center of  manufacturing in the US. It is interesting to note, however, that a large majority of the PAS units are shipped to commercial and residential customers alike in the two coastal areas.

In addition, PAS ships a substantial number of units overseas to all continents where they are mostly used in the commercial, institutional and medical markets. Since the blower/motor systems are rated 120/240 volt 50/60 Hz, the units can be utilized anywhere in the world.

The HEPA units are capable of producing up to 2000 CFM of air through certified, scanned HEPA filters that have an initial efficiency of 99.99% at 0.3 microns. All of the PAS units also incorporate granular activated carbon filters for the reduction and/or removal of gaseous pollutants. In this way the systems are capable of being used in applications where airborne particulates are present along with odors or gases. Since these units use powerful motors ( up to 1 HP ) they can be used to move air through duct work and are often used to either make a room positive or negative depending upon the requirements.

Today PAS is looking at building a new system specifically designed for the medical market and this system will be fabricated in the east coast area. This is a departure from its Midwest roots but a necessary part of its growth going forward. More information on this new product will be in future blogs on this site.

It’s The End Of The World As We Know It

The prophets of gloom and doom are always out on the side lines predicting the demise of man…self made no less. It seems like every change by a despot or ruler of a foreign county constitutes major peril to the entire world. The  sequester, changing of the guard in North Korea and climate change are but a few of those apocalyptic events that seem to rock the universe. To those problems  I say…Eh!

The truth is there are more real issues in the world that could eliminate or minimize the level of humans who live on this sphere in the universe…and they are very, very tiny. Yes, we are talking about bacteria and viruses. Those tiny, less than 10 micron sized living entities that dominate the earth in astounding numbers. It has been proven that despite man’s attempt to change human kind and the planet we are facing the reality that “nature always finds a  way” to adopt. New pesticides for farmers has generated a new strain of bugs that love the stuff. But the battle of finding new vaccines and antibiotics that will kill the ever evolving drug resistant bacteria and virus strains may just be the one battle we may lose.

There are now serious concerns on the part of the medical community that many people will die as a result of these new drug resistant strains. The fact that the flu vaccine this year had little effect for those who got vaccinated is a good indication of just how fast these new “bugs” evolve.  Close quarters and crowded spaces make the transmission of these airborne pathogens simple and easy. This is also complicated by the transmission of surface born pathogens that can affect hundreds of people that eat in just one restaurant or take a vacation on a cruise ship.

Airborne bacteria and many viruses can be removed from the air by using commercial grade, certified HEPA based air filtration devices. Systems such as those produced by Pure Air Systems, have the ability to move up to 2000 CFM of HEPA filtered air and come in a wide range of sizes and configurations. Since 1985, Pure Air Systems has been manufacturing these high end, commercial grade, high performance HEPA systems that are now used around the world. Many of the PAS systems are used in hospitals, clean rooms, clinics, laboratories and critical applications where reduction and or removal of  harmful airborne particulate is required.

The PAS systems are currently used in applications including, institutional, industrial, residential, medical, commercial and governmental. In many instances, the PAS systems are the only HEPA unit available on the market that can provide the type of sub-micron particulate removal needed to ensure the safety of people and equipment.  The PAS line of HEPA and Carbon based systems can either be attached to existing air handlers or HVAC equipment or be used as stand-alone systems.

Take a Breath…Take a Deep Breath Now.

As humans we take a lot of things for granite. Rotation of the earth which produces gravity, land to walk on and water to swim in, and the ever present source of life, the Sun.  Being able to breathe the atmosphere in our environment is also something we take for granite. Interestingly most of us know little about the air we breathe. For example, the atmosphere we exist in is comprised primarily of oxygen and nitrogen. Oxygen comprises 21% while Nitrogen comprises 79%..( actually a little less than 79% as there are some trace elements in the atmosphere as well). In reality we are actually Nitrogen breathers although at the surface pressure of 1 atmosphere our bodies don’t absorb the Nitrogen, but they do take in the Oxygen.

When you have a cold or some form of upper respiratory infection you often find it is difficult to breathe. In actuality the lungs are probably full of mucus and the surface capacity of the lungs to take in Oxygen are significantly reduced, therefore requiring longer and deeper breaths just to get the amount of Oxygen your body requires. This same problem exists when you have lung damage due to smoking or breathing large quantities of airborne particulate in your work place over long periods of time. Ingestion of small, sub-micron sized particles create challenges for the lungs as these particulate tend to stay logged in the lung linings and mucus membranes.  People who smoke have difficulty in running or walking long distances as they get “short of breath” very quickly.

Small concentrations of harmful, respirable sub-micron sized particles, inhaled over a long periods of time can also significantly impair the lungs ability to take in Oxygen. Individuals who work in environments where dust is generated on a continuous basis are more susceptible to lung damage than those working in an office type environment. Even when technicians where masks or respirators, these individuals are more at risk than most.

In 1985, Pure Air Systems was founded to provide a series of commercial grade HEPA and Carbon based systems for the residential, commercial, institutional, industrial and medical markets. Today, the PAS line of HEPA, fan powered systems are used in a wide variety of high performance applications around the world. Removal and reduction of small particles are the key benefit of using HEPA filters. Those used by PAS are initially rated at 99.99% removal of particles 0.3 microns or smaller and approach 98% removal of particles 0.12 microns and larger.

Over the years many home owners have purchased the HEPA units from PAS and found the number of colds, upper respiratory infections, allergies and even headaches were significantly reduced. The same is true of those companies and medical operations that used the PAS HEPA systems. Product through-put, reduction in transfer of airborne pathogens and allergens, increase in product quality and reduction in loss work time for employees were all positively affected when using the HEPA systems on a regular basis.

HEPA System Working At Minus 34 Degress C

In the over 27 years that Pure Air Systems has been manufacturing and selling commercial grade, high performance HEPA and Carbon based air filtration systems, we have installed our systems on some of the most unique and unusual applications and locations. From oil tankers in the Middle East, mobile surgery units in Africa and units in evidence rooms in police stations, PAS systems have been used in applications that required high performance in severe environments.

Over the past six months, the High Altitude Observatory, a division of the National Center for Atmospheric Research has been testing an highly specialized optical instrument at their laboratory in Boulder, Colorado. This instrument will eventually be shipped to the HAO in Hawaii. Because of the critical nature of the environment in which this instrument must operate, the unit will require an ultra-clean air flow the instrument at temperatures ranging from minus 5 degrees C to plus 40 degrees C.

The HOA purchased one of the HPS 500 portable HEPA units from Pure Air Systems to test its overall capabilities six months. They tested the unit and made sure it would work within the overall boundaries of the operation window for the optical instrument. The HPS unit passed with flying colors and now the HOA has purchased a second unit for their facility in Hawaii. Their only real concern was the operation of the motor at these extremely low temperatures.

The EBM blower/motor used by PAS, is a German made unit that is designed to operate in extreme cold and heat. The operational parameters of the EBM blower/motor are well within the operational requirements set by the HOA and NCAR. The units will be running on a 24/7 basis so durability and performance are paramount in this application. The fact that  Pure Air Systems was able to provide the type of HEPA filtration system HOA needed is not surprising. PAS has been providing the best commercially made, high performance HEPA systems to the commercial, institutional, medical, industrial and residential markets since 1985.

Pure Air Systems offers a complete line of HEPA and Carbon based, fan powered, certified HEPA units ranging from 50 CFM to 2000 CFM and in seven different configurations and designs. These systems can either be used attached to an existing HVAC system or as stand-alone units. With the exception of the HPS series, all of the PAS units utilize the newer ECM variable speed, digitally controlled motors that are rated 120/240 volt, 3 phase, 50/60 Hz.

Portable HEPA Systems

Portable HEPA units have been around since the early 80’s. The majority of the early versions were round, using a doughnut shaped HEPA filter, wrapped with a prefilter/carbon media to capture the larger particles. The blower/motor was inside the HEPA and pulled the dirty air through the HEPA through slots or holes located  in the outside of the case and the clean air exited through the bottom.

Most of the early versions had three speed motors so you could adjust the volume of air based upon the size of the room or amount of noise you could tolerate. The air volume movement for the units, as measured in CFM, ranged from 50 CFM to 250 CFM. However two major problems occurred with these units. First, any speed setting above the lowest one created enough noise to make you slit your wrists…twice. Second, the rated air flows never approached the stated CFM volumes from the manufacturers. This meant you had to run the system at its lowest setting if you were in the room and then it would take a very long time to clean all the air in that room. But they were the only game in town.

Subsequent portable HEPA units were not much better. Where the original was made from metal and heavy duty plastics, the newer units, mostly imported from overseas, were all plastic. They were just as noisy as the first units but were less expensive and the replacement filters were cheaper. These units used what was called, faux HEPA filters. They were not certified or designed using any of the certified HEPA filter rating systems but they were still called HEPA units. The public had little choice to purchase these if they want HEPA filtration for their indoor environment.

Pure Air Systems was started in 1985 and from the beginning used only commercial grade, certified, metal framed HEPA filters in their systems. Over the years PAS developed a range of larger units using variable speed, digitally controlled motors that could move from 100 CFM to 2000 CFM of HEPA filtered air. And do it rather quietly. These systems were designed to be attached to existing HVAC systems or be used as stand-alone  units.

In 2005 PAS began working on the design for a new portable HEPA unit that would be a commercial grade, powerful and quiet unit with air flow volumes two to three times the levels of the current units on the market. These systems had to be small and light enough to be easily transported and be rugged enough to with stand the abuse of use in commercial and institutional environments. After 16 months of trial and error the HPS 350 and HPS 500 were born. The most powerful and effective true HEPA portable units on the market today.
