For many commercial and residential HVAC systems, air filters and/or carbon media adsoprtion media filters, are located on the downstream side of the air handler ( fan ) section. These filters see all of the air from the return air system. Over time, these filters will get very dirty and start to load up and create some additional resistance across the air handler fan. This additional static load will actually reduce the amount of air flow since the higher resistance will create an issue for the fan and motor and thus reduce air flow. This means it will take longer to heat and cool the building structure using more power.

If you are using a high efficiency filter like a HEPA media filter, these filters have an extremely high resistance when clean and the pressure drop across the filters gets very high as the filters load up. In addition, you really need a medium duty air filter ahead of the HEPA filter as the HEPA is really designed to remove very tiny (sub micron ) particles ( think Bacteria and Viruses ). Therefore, putting this combination of high efficiency filters and HEPA filters in line in the air handler is very difficult.

To resolve this issue, Pure Air Systems, uses their fan-powered HEPA based air filtration systems that are incorporated into the return air side of the HVAC system. By taking only a portion of the air from the main return air duct and then putting that back into the air handler upstream of the fan, the PAS units can filter a portion of the air through very highly efficient HEPA filters without affecting the pressure drop across the main air handler fan. While this approach only takes a portion of the return air, over a 24 hour period, this concept will filter all the air in the home or office 24 to 48 times per day.

For the past 40 years the use of UV lights in HVAC ducted systems has been promoted as a way to eliminate mold and bacteria from the inside of the HVAC air handler. These UV light systems are normally located in or near the fan coil area where moisture is most present. These light systems are often used in-lieu of air filters or specifically HEPA air filters. One of the main reasons for using the UV lights is that they do not create any additional static pressure across the fan so that the air flow remains constant and stays at the correct air flow for maintaining proper heating and cooling of the indoor environment.

While it is true that HEPA filters or high density filters will create additional static loads on the air handler fan and can reduce air flow, the HEPA filters are much better at removing the airborne mold, bacteria and other contaminants, especially the smaller sub-micron particles that can truly affect your respiratory systems.  

The challenge with using UV lights, is that fact that the air flow from the fan passes by the UV at a very high rate of speed, and they airborne contaminants are not seeing the UV light rays for very long and in many cases the UV light does not destroy or kill the mold, bacteria or viruses. Even after multiple passes, the overall efficiency of the UV lights is minimal. As a comparison, if you are passing all the air all the time through HEPA or high efficiency air filters, all the air all the time is being filtered and the air filters will actually capture the particulate and keep it from re-entering the air stream.

One reason that people tend to stray toward using the UV light systems is the fact that HVAC contractors find that installing the UV light systems is easier and requires virtually no maintenance and most people have little knowledge of particle removal or efficiencies of air filters vs UV light systems. It is important to understand the differences between these two processes and remember that air filters are always a better option than using light as a means of minimizing the levels of harmful bacteria in the indoor environment.

Pure Air Systems was founded in 1985 with the specific intent of bringing commercial grade HEPA based air filtration systems to the residential and industrial markets. Over the years PAS developed 7 different system configurations that could either be attached to an existing HVAC system or used as stand-alone units. 

Over the years PAS has improved its air filtration systems by incorporating programmable variable speed drive motors that can now be operated with an app on your cell phone. This allows for infinite air flow adjustment for best filtration efficiency and performance. This process provides a unique advantage of using the PAS line of HEPA filters over all the other competitors in the market. In fact, Pure Air Systems, Inc, is one off only 3 companies in the world that make this type of air filtration system.

The PAS HEPA systems use all metal housings and can incorporate a variety of filter types in their units. These include the scanned 99.995% HEPA filters, carbon media filters and ring panel pre-filters. The system range in air flow capacity from a low of 50 CFM up to 2,000 CFM for the larger units. The systems can be used strictly as odor or gaseous removal systems by using just the pre-filter and carbon media filters without the HEPA. This makes these systems extremely flexible as they can be modified in the field with different filter arrangements in a matter of minutes.

Everyday there is information provided regarding the level of outdoor air quality and it’s potential affects. The levels can range from good to very poor. While some people with severe allergies or respiratory issues value this information, most people pay little attention to these outdoor air quality warnings because most of us are indoors the majority of our time. Either at home or work or both. And we believe that being inside is much safer and healthier. And nothing could be further from the truth.

Indoor air quality is maintained, primarily, by the HVAC systems that both heat and cool the interior spaces. These systems recirculate the air with very little fresh air being introduced into the home or building creating a somewhat stagnant indoor air environment. The air filters that are used in most HVAC systems are general duty filters designed to capture very large dust particles that are airborne. These filters don’t capture bacteria, viruses or various forms of allergens. This means that all the airborne particulate are being recirculated throughout the interiors spaces for everyone and anyone to breathe. 

Most new homes are now designed so that when the HVAC units are running the home is under positive pressure, meaning no outside air is being introduced into the interior spaces. While this keeps the home warmer in the winter and cooler in the summer, the lack of outside fresh air creates a very unhealthy indoor environment. But there are solutions to this problem.

Pure Air Systems has been manufacturing HEPA and Carbon based, fan-powered air filtration systems since 1985. This US based company makes a line of systems that can be attached to the return air side of your HVAC unit and because they have their own fan assembly, they can be installed to introduce small amounts of fresh, filtered, outside air into the home or office. Since the HEPA filters are designed to capture bacteria and many types of viruses along with other allergens, The PAS units provide the perfect solution to keeping the air in your home or office clean and fresh.

In today’s market place it is becoming increasingly difficult to stay ahead of the competition. The advancements being made with the use of  AI for design and rapid product development have provided a more level playing field for companies anywhere in the world. The advancements being made in manufacturing, design, robotics, materials science and medical devices are available to small companies in Vietnam as well as Kansa City. As long as you have a computer and access to the internet, you can succeed in anything.

For the older generation, this all seems a little crazy. They grew up in an environment where changes came slowly and you had a number of years to adapt to these changes. Today, all forms of communication, online bill paying, no access to a real person to get information or complain about a product or process, they are now done through apps or Bots if you use the phone or Chat online.

Pure Air Systems, Inc., a manufacturer of high end, commercial grade HEPA and Carbon based, fan powered air filtration systems, has been in business since 1985 and joins the ranks of a small group of companies that have been in business for that period of time without being bought out or merged with another corporation. Since it’s inception, PAS has managed to stay competitive and become one of only 3 companies in the world that still make these types of systems. This is no small task. Constantly looking for new components and increasing the use of digital technology, PAS now has systems that use programmable motors operated by the customers using a Bluetooth technology. This provides the customers with a system that can be constantly modified to meet the demands of the customers operation.

Since it’s beginnings in 1985, Pure Air Systems has strived to push the limits of available technology to continue to improve its HEPA based air filtration systems and offer more operational flexibility for its commercial and residential customer base. During the early years of operation PAS used the common induction motors for their systems. These were limited to one speed and limited the amount of volume adjustment in the filtration systems. 

In 1999, GE produced a new variable speed drive motor known as an ECM motor. This motor was a total departure from the wound copper induction motors as it use magnets for its drive mechanism. It could run forward or backwards and could be controlled digitally to operate in 1% increments from % of volume to 100% of volume. PAS was one of the first companies in the US to test this motor and eventually incorporate it into all of our systems. Additionally, these motors could be used in 120/240 50/60 Hz applications, making them perfectly suited for use overseas where most electrical systems are 240 volt/50Hz. This allowed us to open up new markets in Europe and Asia.

In the past year the the 2nd generation of these motors now allows us to operate them using Bluetooth apps on any smart phone. This gives the customer complete control of the HEPA systems no matter where they are located. And, the new motors can be programmed for different HP requirements from 1/3 HP up to 1 HP and run at full speed even when the pressure drop across the HEPA filters gets as high a 3.3 inches of static pressure.

Beginning in 2006, many of the major manufacturers in the U.S. decided that labor costs were too high here and that competing with overseas companies required a different strategy. The companies shipped both their R&D and Manufacturing operations overseas. Mostly to China and Indonesia. Some had offices in those area but those were absorbed by the other countries. This also included the tech industries who required employees with specialized skill sets and allowed did design the products here but had them made in China.

With the advent of Amazon on the scene, the American public began purchasing items based on cost not on where it was made. Today China makes over 65 % of the products we use in the US and some are now made in Vietnam, Cambodia, India, Ireland and Mexico. In addition, the vast majority of high end electronics now also come from Japan and South Korea. You can’t purchase a TV made in the U.S.

Manufacturing is a very difficult and expensive process and building new plants requires a few years of investment with little profit. So, while many people believe that the new tariffs will change that equation, they are not dealing in reality. Also, any new manufacturing  visa-vie Tesla, will be done using the robots now being produced in the U.S and overseas. People are too expensive and we no longer have the skilled technical labor to create this companies. Even Apple has admitted that the labor costs in China are no longer cheaper but the highly technical manufacturing processes they now have in place are far superior to what we have in the U.S.

Pure Air Systems, Inc., a U.S. based operation makes some of the most sophisticate HEPA based, fan-powered, digitally controlled air filtration systems on the market and is now only one of three companies in the world that still make that type of product. PAS has had to purchase some of their components from overseas operation because they are no longer made here but continues to use as much U.S. made components as possible for their product line.

There are thousands of ads and videos on all of the social media platforms that prescribe some unique drugs, diets, exercise routines or equipment that will help remedy what ever aliment you might be dealing with. They promote simple solutions to complex problems and we all know that never really works.

Pure Air Systems as been in the commercial air filtration business since 1985 and was one of the first companies to offer true, commercial grade, fan powered HEPA based air filtration to the residential market. The PAS units include metal framed systems that include variable speed motors with digital controllers that range in volume from under 50 CFM to 2,000 CFM. All of the systems can be used independently as stand-alone units or attached to existing HVAC ducted systems. PAS also offer a true Portable unit that can be used in any room and taken with you on trips if necessary.

The fact that all homes, especially new ones have been made to be more air tight creates an environment where airborne particles, including bacteria and some viruses remain airborne a long time and are constantly being recycled by our HVAC unit. And, the air filter that is placed either in your main HVAC air handler or those place on the return air vents in you home are only designed to handle very large particles, usually in the size range of 100 microns and larger. 

True commercial grade HEPA filters, like the ones used in the PAS units. are designed to capture 99.99% of all particles 0.3 microns and larger and become even more efficient over time. Since most harmful bacteria are 10 Microns and smaller and viruses smaller that than that and will pass through a standard face mask like those used in the pandemic.

Have a customer who thinks they know more about your product than you do and can site facts from 20 years ago to prove it? And, they want answers to un-answerable questions? Welcome to the new world of main street business. Yes, customers can be down right nasty and intractable and it is getting worse. This is not always the case, but if you are dealing with a more senior individual there is a better chance of having a major discord with this individual.

One of the reasons for this challenge is the fact that many people now have to either converse with a Bot on their computer or talk to an individual thousands of miles away with a foreign accent that they can’t understand.

Go back 30 years and customer service was the epitome of many companies and they touted their ability to deal with your issues like you were part of their family. And, many companies were family owned and operated or the corporations actually had compassion for their customers. Money was not the only object. Repeat business was king.

Today, you need to have a phone, computer or tablet to order, track, pay for and return any item or service. In many cases major transactions can take place  like selling or buying cars, homes, boats, etc. without ever talking to a human being. Airline reservations are done on-line as is booking hotels, buying groceries and getting your plumbing fixed. If you throw in the use of AI, there are operations where you are having a conversation with a computer generated program that is as effective as using a human being. 

Pure Air Systems got its start in 1985 with the old fashioned process of going door to door and making products that worked extremely well. Every aspect of the selling process as face to face and person to person on the phone. ( corded version) If you needed a replacement part we had it in stock and it was sent out the next day and a follow up call was made to make sure the customer was satisfied with the replacement. Extended conversations with customers on how to set up or operate the equipment were common place. There were no bar codes or QR codes to use to access a website. 

Today, Pure Air Systems relies heavily on its website to promote and educate potential customers as well as offer detailed descriptions of their line of HEPA based air filtration systems. Customer service is still done verbally via phone of email and the products are still made with the best performing parts available on the market.
