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.

Activated carbon has been used in a multitude of applications to reduce and/or remove odors and gaseous pollutants from organic and inorganic materials. Carbon pads or granular carbon is often included in water filtration systems as well as air filtration units in both residential and commercial applications.

Activated Carbon is usually made from cocoanut shells and then heated to high temperatures to expand the material to allow for a high capacity of adsorption of gases and odors. Carbon can usually adsorb ( with a d rather than a b ) 100 times its weight in gaseous pollutants and will eventually release these odors once it has reached its adsorption capacity. 

There are specific formulas that are used to determine how much carbon ( in lbs ) will be required to handle a level of gaseous pollutant at  cubic foot/minuet flow rate. The higher the flow rate in CFM ( ie:  500 CFM ) the larger the amount of carbon needed. It is also possible to determine the frequency of replacement of the carbon in time based on these calculations. 

Pure Air Systems has been making HEPA and Carbon fan powered, commercial grade air filtration systems since 1985 and offers seven different sizes and configurations that can include all Carbon media or a mixture of Carbon media and HEPA filtration.

Pure Air Systems has been making HEPA and Carbon based, fan powered, commercial grade air filtration systems since 1985. With over 40 years of experience, PAS is one of only three companies in the world that have this expertise and PAS now offers app driven programs to run your HEPA and Carbon based air filtration systems for your commercial operations.

Pure Air Systems offers seven different configurations of their 600HS, 1200HS and 2000HS units along with their unique Portable unit. These systems all employ the newer, programmable Variable Speed Drive motors that can be adjusted from 1% to 100% of volume and now can be controlled from your smart phone using our special app. This allows for remote operation from anywhere so you can have the units running at any speed at any time from anywhere.

The PAS systems range in air flow capability from 50 CFM up to 2,000 CFM and the units can be configured to work with existing HVAC systems or as stand-alone units. The HEPA filters are all scanned HEPA’s meeting or exceeding 99.9995% efficiency on particles 0.3 microns or larger. These units are often used in clean room applications as well as medical facilities and anywhere the removal of harmful airborne contaminants is required.

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.

The new import tariffs against China and other countries will make component parts and about 80% of what we purchase, more expensive. There is little truth in the fact that many of the companies that are overseas will now return to U.S. shores. Unfortunately, all the companies overseas are either owned and operated locally or are part of an international partner. For all intents and purposes, the U.S. has pretty much given up on building new manufacturing plants as most larger corporations would rather design products here and have them made somewh   ere else. Or if they are going to manufacture in the U.S. they will be using Robotics and few people. 

Intel, one of the largest and most profitable companies in the world, just stopped production of two huge Chip Manufacturing plants in Ohio because of slower chip demand and the fact they have lost over $186 Billion in their stock. They hired a new CEO and put the plants on hold until 2030. Making anything is very difficult, especially high end tech products. Apple designs their iPhones, etc, but they are all manufactured overseas. 

Pure Air Systems, Inc., an Indiana based corporation, has been manufacturing high end, fan-powered, HEPA based commercial grade systems since 1985. While some of its components are now manufactured overseas, 80% of the systems are made from American made components. And now, after 40 years. Pure Air Systems, is one of only 3 companies in the world that make this type of high end product. It is very difficult to compete in the world market when you are constantly searching for suppliers that can meet your demands at a price that allows you to make a profit.

Even though the industrial market has changed and many products are now made overseas, there are many small, specialty manufacturing operations that are using welders, sanders, chemical processes and semi-cleanroom manufacturing systems.

Most of these operations are done inside of small shops or buildings and all of them require some form of dust or gaseous odor control. The utilization of just using a exhaust fan to the outside is still used but in most cases this is no longer allowed as this effluent is going into other businesses or adjacent homes. In addition, when you are exhausting 300 cfm to 1000 CFM of air from inside the building you are throwing out cooled or heated air and have to replace that with make up air and that is expensive.

Pure Air Systems has been making fan powered, commercial grade HEPA and Carbon based systems since 1985 with air flow capacities from 50 CFM to 2000 CFM. These industrial, metal framed units can be used as stand-alone units or can be attached to existing, ducted HVAC systems. These units can be attached to a hood that is placed over or around the industrial process and capture the exhaust gases as well as the particulate and then have it brought back into the room either through a straight duct or into the existing HVAC inlet to be reheated or cooled.

The PAS units can also be fitted with just all carbon for gaseous fume removal or carbon and filters or all filters depending upon the specific application. This makes these units multi-functional and all filters are interchangeable. The motors are all variable speed, digitally controlled and programmable so you have a lot of flexibility for ventilation if your operation has more or less exhaust air for controlling the effluent.

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.

Searching for that special tool or clothing article on Amazon you will find hundreds of options with tools and clothes of many styles, materials and designs. One would think that with all those choices that some of those items would be made right here in the USA. While many items do not indicate their country of origin, when your Amazon package is delivered and the product is removed, 99% of the time made in China or some other foreign country is stamped on the label or item itself.

With the exception of most medical equipment, some machinery, autos and airplanes, the majority of everything else we use in our daily lives is made outside the US or with some components from outside the U.S. It has become more expensive and more challenging to compete with products from other countries as they have greatly improved their technologies or developed something we never made in the US. OLED TV’s are an example. All of this technology was developed in South Korea.

The US has lost most of its’ experienced automotive, aerospace and scientists to old age and retirement. The newer generations are much more into the digital markets such as AI, AR and VR headsets, cell phones, computers for gaming, specialized sports equipment and some new automotive technologies.

Pure Air Systems, was started in 1985 selling modified HEPA based air filtration systems for the residential market and over the past 39 years is had added 7 new systems to its line of high end fan powered air filtration systems with 90% of the components being made in the US. Their systems are now sold all over the world and they are one of only 3 companies in the world that currently manufacture these types of systems.

The manufacturing world is awash with new concepts and techniques. The use of AI along with Additive Manufacturing and Robotics have enabled many start-ups and small product development companies to offer better products that meet or exceed the expectations of their current customer base.

The use of AI in every aspect of their company structure, from marketing to customer support and product enhancement have created a need, in many cases, for a different breed of employee. In many cases their current base of employees don’t have the expertise to use many of these new concepts. Also, the addition of  VR and AR technologies are providing for collaboration with experts outside their own company to speed up the development of new products and get them into the market faster. The world of technology is now moving at light speed.

Many companies that use CNC machines for making steel parts have additive 3D printers or Additive Manufacturing  do both prototyping and in many cases actual manufacturing in lieu of their CNC machines. This affords faster design changes and the ability to make products that can’t be made using CNC operations.

Pure Air Systems is a manufacturer of high end, commercial grade, fan powered HEPA air filtration systems for both the residential, commercial, industrial and institutional markets. They have been in business since 1985 and were one of the first companies in the US to incorporate ECM motors into all of their systems. They now offer systems with complete digital and computer controlled motors to handle every type of air filtration application.

When Pure Air Systems was established in 1985, there were a number of companies selling HEPA like and HEPA type air filtration systems. Many of these were used in the Asbestos Abatement projects that were prevalent at that time. In fact, Pure Air Systems was a spin-off from HEPA unit designed for abatement but never got into production.

The model 600H unit was a unit with a prefilter, carbon media filter and true commercial grade HEPA filter with a 1/3HP GE motor and Lau Blower. It was in one large section which was subsequently broken into two sections. This was the beginning of the PAS Line of HEPA systems. 

As the popularity of the 600H unit grew, PAS introduced the new ECM motors from GE to make the HEPA system available as a stand alone unit as well as using variable speed motors that were then being introduced by all the HVAC companies.

By 1999 PAS had grown the line from one unit to seven different systems including the new portable unit. It has also moved into a new 9,000 square foot building. As of this date, 90% of the units are still built with parts made in the USA and it is now one of only 3 companies in the world that make this type of HEPA with the size and flexibility in size range and air flow control.
