HEPA and Carbon Filtration With HVAC Combined

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.

Air Filters VS UV Lights

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.

Why Manufacturing Is Not Returning To The U.S.

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.

Pure Air Systems Moves Into It’s 40th Year Anniversary

In 1985 and idea to use commercial grade, fan-powered HEPA based air filtration systems was devised by Don Musilli. The concept of using a large HEPA system in conjunction with a standard, forced air, heating/cooling system was never tried before. Normally, contractors just installed a standard pleated air filters or in the early days they used electronic air cleaners, which never really worked that well.

When Pure Air Systems was formed it was a long work in progress and working out of a home office with one old computer and the first use of what was to become the internet as we know it now, but then it was primarily only a landing page and you either used AOL.com or Yahoo.com. Both start-ups. Years later as PAS grew we formed our own URl and found that the use of the World Wide Web had become a very important part of our marketing program which provided almost 60% of our sales leads. 

10 years later after working out of our home and garage we finally had enough money to purchase some land and build a 9,000 square foot building and starting designing different sized units and our sales started to really grow as we added some systems that were four times the size and power of our original 600H unit. By 1999 we started to use the new GE ECM variable speed drive motors that were capable of running at any speed and could be used anywhere in the world. 

By the early 2000’s we had developed 7 different systems that could be used either as stand-alone units or attached to an existing HVAC system and for almost any commercial, industrial, consumer or institutional application. We had to develop a new way to package the units as we had decided to divide each unit into two sections. One housed the blower/Motor and controls and the other half had the three filters. A polyester ring panel prefilter, a carbon media filter and a true commercial grade, certified HEPA filter. We could also use higher grade SULPA  filters for certain applications.

In 2006 Pure Air Systems was sold to Dave Hearns who continues to provide the same high quality systems that now incorporate programmable ECM motors with customer options to change the system air flow and time to run on the fly.

Meeting The Unbelievable Expectations of Customers

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.

The Changing America

The WW II generation is almost gone from this planet and the Vietnam era baby boomers are now retiring. The WW II generation was mostly responsible for the age of manufacturing in the US and the baby boomers brought the age of technology to the world. For the most part, manufacturing has been transferred to other countries and technology in all its forms is now the booming industry in America. Throw in the new age of AI and you begin to see an emergence of the new America. 

With the ability for many young people to make a living using digital technology, whether from an office of their home, there is little incentive to get into the trades or any type of manual labor, including the service sector. As a result, you are seeing a major shift from the older, more traditional work for a company for 40 years to work for 20 companies for 40 years, including working for themselves.

This shift is creating employment challenges for retail, the service sector and the trades. It is, in fact, the reason you are seeing so many restaurants go out of business and many retail store chains are either consolidating or shutting down, to the chagrin of the older generation. This transition has not yet hit its stride. By 2030, the industrial revolution as we know it will be replaced by Robotics, AI, Additive Manufacturing, working from home and a shift to fewer or no children in marriages. 

Pure Air Systems was founded in 1985 and is now one of three companies in the world that produces high end, commercial grade, fan powered HEPA based filtration systems. Initially, the first systems used the older, induction motors and then progressed to the Variable speed drive motors and now the new programmable VS motors. The use of analog controls have been replaced with digital controllers producing systems that can be matted to computer controlled operations.

The High Cost of Better Components

Everyone is seeing higher costs for most manufactured products from cars down to folding tables. There are a number of reasons for this major increase. First, labor costs have gone up, and even though many companies are now using robots and advanced machinery, labor has increased by 10% to 20% in many operations. Secondly, getting parts from other sources has become more expensive due to two major changes, an increase is shipping costs and higher materials cost on the end of the manufacturer. 

Lack of manufacturing in the US has also created higher costs due to limited competition. In many instances, identical parts that were made by 10 to 30 different companies are now only made in 1 to 4 companies and they are suffering from lack of experienced labor. With fewer young people going into any form of manufacturing the supply of all types of parts will be limited to the overseas manufacturers and they can charge whatever the market will bare.

Pure Air Systems has been manufacturing commercial grade, fan-powered HEPA and Carbon base air filtration systems since 1985. These metal framed units incorporate large blowers, variable speed motors and high end HEPA filters. Like other manufacturers here in the US, the prices of all the components that make up the Hepa Shield systems have increased dramatically since the inception of the company. It has been, however, Pure Air Systems goal to continue to provide quality components and maintain their reputation for performance even if they have to raise prices to cover the increased costs.

Using AI To Improve Design Efficiency

Artificial Intelligence is now mainstream and the use of this technology has reached global proportions. Companies, research centers, Universities, military establishments, social media operations, financial institutions, etc, have all incorporated various versions of AI into their day-to-day operations. And, they are all seeing the benefits in the use of AI. In fact, most companies are new facing an up-hill battle in the area of advanced technologies if they have not incorporated AI into their mainstream operations.

Companies such as Tesla, SpaceX, Boeing, NASA, Airbus, GM, Ford and other major manufacturers are seeing huge benefits in equipment design and enhanced processes never before achieved using the old add-on technology process. The quantum leaps in Bio Chemical science are a result of using AI which have now altered the way certain drugs are now being modified for use in more applications with better results.

The Chinese have been using this technology to try to compete with SpaceX to offer reusable rockets for less expensive launches of their satellites. The European countries are now using AI in almost every aspect of their business economy and especially with their continued efforts in the reduction of green house gases.
