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.

I have been playing around with the new Google AI app, Bard. It is fast, and easy to use. Further more, it will create anything you ask it to create. The more and better the prompt information you input, the better the end result. I have already used it to write some simple contracts. 

In the field of engineering, AI apps are helping entrepreneurs and manufacturing and design companies to both enhance existing designs and fabrication techniques but also developing whole new concepts is product development. And while there are skeptics out there who believe AI is the end of the world as we know it, this technology is growing so fast that in another 3 months it will become ubiquitous in the field of writing and creating everything.

ChatGPT and other AI apps are gaining popularity and there are now more than 15 of these apps out in the market place. Yes, students are using it to write term papers and do math problems, and this can be an issue down the road, but it also ushers in a new way to increase the speed of creating everything and with fewer employees. This concept has not been lost on major corporations who are already looking for individuals with some experience with these new computer models.

Pure Air Systems has been manufacturing commercial grade HEPA based, fan-powered air filtration systems since 1985 and will begin to utilize this new technology for enhancing its product line as well as writing some of its marketing materials.

Pure Air Systems was founded in 1985 and at that time the electric motors used in their HEPA based air filtration systems were typical wound motors. These motors were only capable of running either at one speed, or 3 speeds if adjusted to the speed controller. They were also either 120 volt, 60 Hz or 240 volt, 50Hz. 

In 1998, PAS along with General Electric, started to play with the new ECM, variable speed drive motors that were magnet driven and not the typical induction motors used in the past. These new motors could run forwards, backwards and could controlled to run at 1% of power up to 100% of power in 1 percent increments. And, they were rated from 1/3rd HP up to 1 HP using the same base unit but by changing the drive add-on could be changed from 1/3rd HP or 1/2 HP to 3/4 or 1 HP simply by changing the controller section. 

In addition, by using digital controllers, the customers had the ability to change the speed of the motors and the level of filtration from any location in the room or proximate to the filter systems. These units could also be programmed to operate on a pressure differential basis so as to speed up the fan motor when the HEPA filters started to load up and create more static load. This allowed for continuous speeds throughout the life cycle of the HEPA filter.

The newer versions of these motors now allow for complete programing functions either from the factory or by the end user with some minor education by the factory. These newer motors, like the original variable speed drive motors, are now 120/240 50/60Hz so they can easily be adapted to working anywhere in the world. These new motors are used on the complete line of HEPA based air filtration systems offered by PAS. Models, 600HS, 1200HS, 2000HS, and the HPS Portable HEPA filter systems.

Innovation is a word that is often over used in today’s market place. Some new ideas or concepts are just an alteration to an already existing product that is being labeled “innovation.” 

In I985, Pure Air Systems was formed and it introduced some new concepts in fan powered, HEPA air filtration systems for both the residential and commercial markets. With an All-American made system, Pure Air Systems ventured into the air filtration market with a commercial grade, high performance, true HEPA filtration system that could be used in a wide number of applications, both residential and commercial. Initially, the PAS line of filtration units was limited to one model, and it incorporated the standard GE Induction motors and no bells and whistles.

By the 1990’s PAS had developed 5 additional models varying from the new HPS Portable line to the very large 2000 CFM 2000HS Plus unit. These new units were now using the new variable speed drive, ECM type motors that were rated, 120/240 Volt, 50/60Hz. This provided systems that could be used anywhere in the world. In addition, the new motors could be used with digital variable speed controllers offering customers the ability to adjust air flow and power performance to meet any performance specifications.

Today, Pure Air Systems is one of only 3 companies in the world that produce this type of commercial grade, high performance HEPA based air filtration system.

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.

When people purchase a home their primary concern is size, number of bedrooms, baths and back yard size. Concerns about the HVAC system, the heating/cooling unit, are seldom brought into the decisoin, Yet, this unit and associated returns, supplies and duct work, can make your home a dream home or living nightmare. Today, in most areas of the country it is now required to have a blower door test to determine if your home is postitive or negative when the HVAC system is operational. If the test shows the house to be positive, meaning that air is being pushed against the interior of the house and keeps the home from any infilatraion from the outside. Obviously, the opposite occurs when the tests show the house to be negative. Under these conditions the house will actually suck in any fine particles through any passage way between the interior and exterior of the home. This means more dust and allergens as well as bringing in more moist hot air in the summer and cold dry air in the winter which make the HVAC system run longer and work harder and crate higher energy bills.

Sizing of the HVAC system should be done by professionals and higer Seer rated systems are must more efficient over the long haul. You may want to have a blower door test done on your home if it is 10 years or older. if the house is negative is it possible to make some modifications to the returns and supply runs to adjust for this issue. Using the correct size and rated filter for your home and system is also critical. The more efficient air filters may work better at removing airborne particulate but if they are too restrictive they can reduce the air flow through your HVAC unit and crate negative pressure in your home. In any case, keeping your home pressurized is the positive way to go.

It is often said that people don’t want to hear you complain about issues and things that bother you on a regular basis. With the ability to express your every thought using social media, your issues are now broadcast around the world. Yes, everyone wants to vent about something and everyone hopes someone else will jump on their complaint band wagon.

However, when we do have a legitimate issue, especially one pertaining to our health, we do want someone to take our complaint seriously and not reject it as another “boy who cried wolf” emotion.

For 31 years Pure Air Systems has been selling their HEPA based air filtration systems to a wide range of customers including medical, institutional, industrial and residential. A large number of residential customers suffer from allergies or respiratory dysfunctions brought on by ingesting sub-micron airborne allergens and various types of particulate matter. Because the airborne particles are too small to see with the naked eye, when someone in the house or office complained about their severe reactions to the environment most people disregarded their complaints and paid little attention.

But for allergy sufferers and those individuals who really have issues with airborne molds and other building generated airborne contaminants these issues are real and can cause significant long-term health issues. It is ironic the the particles that tend to be trapped in the lung linings and mucus membranes are too small to see yet cause much more damage than the larger, visible airborne particulate that are aspirated in then out again.

The ability for the commercial grade, scanned HEPA filters, rated at 99.99% efficiency, to remove over 97% of these small, sub-micron particles is the reason people continue to purchase the PAS units over other types of filtration devices or systems. With over 31 years of experience in this arena, Pure Air Systems has become a major supplier of high-end, high performance, fan powered HEPA filtration systems.

When purchasing insurance for home or auto you often look at the section marked “Comprehensive Coverage.” This tells you what is covered under the policy with the price quoted to you. This can include covering medical costs, with certain dollar limits, uninsured motorist, which is good to have and a number of other conditions. It does not, however, cover acts of God, which include Aliens crashing their space craft into your car or large creatures eating your seats while you are parked outside your favorite restaurant. No..Comprehensive does not really mean Comprehensive.

HEPA, high efficiency particulate air ( absolute) filter labels do not necessarily mean that this is a true HEPA filter.

In 1985 Pure Air Systems opened it doors offering their first true, commercial grade HEPA filtration system in their model 600H. These metal framed, scanned, 99.97% at 0.3 microns were the most efficient HEPA filters at the time. Fast forward to today and Pure Air Systems offers the same HEPA filters only these are all rated at 99.99% at o.3 microns and work well in the industrial, commercial, institutional, medical and residential markets. In truth, these filters offer Comprehensive Coverage.

The reduction and/or removal of sub-micron airborne particulate is extremely important in many process and medical applications.Hospitals use 100% HEPA filtered air in their operating rooms to reduce the high risk of infection and all clean rooms that manufacture micro-chips use multiple levels of HEPA and ULPA filters to obtain particulate free room levels down to 99.9995% at 0.12 microns. These are normally listed as Class 10 clean rooms.

In the world of filtration, nothing is as effective in removing harmful airborne particles as HEPA filters. All the CDC labs in Atlanta and WHO facilities around the world use HEPA filters to reduce the potential release of extremely virulent bacteria and viruses as these pathogens can often be deadly.

HEPA filters are designed to remove a very high percentage; more than 99.97%, of all particles 0.3 microns in size or larger. In truth they are actually more efficient than that as they become dirty they actually increase in efficiency. This is true of most mechanical filters but HEPA media starts out at an efficiency that is higher than the general duty filters that you use in your HVAC systems after they are fully loaded.

HEPA filters are the ONLY filters used in Hospital Surgery Suites, Clean Rooms, the CDC and any application where the the removal of sub-micron particulate is an absolute necessity. You would be in serious trouble if you have your body was opened up in an environment such as you bedroom. Even if you think it is clean, it is not. Airborne pathogens are a constant cause for infection and having surgery in anything but a 100% HEPA filtered room is asking for trouble.

While HEPA filters are extremely effective in trapping sub-micron sized particles, they are also extremely dense and have a fair amount of air-flow restriction. As a result, larger, more powerful motors and specially designed fans are required to pull the air through the HEPA filter. And, as the HEPA loads up the fan motors must be able to increase in speed to make up for the air flow volume loss that takes place as the HEPA becomes dirty.

Because HEPA filter media ( wet laid HEPA paper ) is so dense it will load up very quickly, a pre-filter media is required in front of the HEPA filter to capture as much of the larger particles as possible and only allow the very small, sub-micron particles to enter the HEPA filter. Without the use of a pre-filter a HEPA filter could load up in a few days and make the HEPA useless.

HEPA filters are available for use in the residential markets through companies such as Pure Air Systems out of Indianapolis, IN. In business since 1985, PAS is the leader in fan-powered HEPA based air filtration systems and they range in capacity from 50 CFM to 2000 CFM. These metal housed units also use variable speed drive motors  ( ECM ) that are rated 120/240 50/60 Hz so they can be used anywhere in the world.

Time, time, it’s all we got and not a lot. So make your time count for you can never get it back. Next week, next month…perhaps next year. You believe you can always find it when you need it.

In my 60 plus years of creating different businesses I have learned one valuable lesson. Procrastination is deadly. Along those same lines, relying on someone else to make important things happen for you is like playing Russian Roulette.

Creating Pure Air Systems was rewarding as it was difficult. Creating a business model in a market that had little understanding of HEPA filters and even less willing to spend money on a product 20 times more expensive than other air filtration systems during the mid 1980’s. The one thing that made this product very different from its competition was the simple fact that it worked better than anything else at that time.

If I had waited for the market to become better educated there is a good chance Pure Air Systems would have never been stated. There is no right time or better time to bring a good idea to the market. The real key is doing your homework and making sure there is a market or potential market for your concept or product idea.

Pure Air Systems is 31 years old this year. It is a testament to the continuing dedication to staying true to its original mission to provide the best commercial grade HEPA based, fan powered air filtration in world.

The company started with one system and added six more over 15 years. Today, new design ideas are still being introduced to make the existing product line even more durable and effective for its very broad base of customers and the over 60 different applications to which these systems have been used.
