HEPA Filtration For Home and Office

HEPA filters have been around for a long time and they are used in a wide variety of applications including hospital surgery suites, commercial air filtration applications, cars, homes and in AI chip manufacturing. These filters are unique, in that they are made from special fibrous paper and extremely good at removing particles in the air is sizes down to .01 microns with efficiencies approaching 99.99999%. 

There are various grades of HEPA filters. The standard HEPA filters are effective down to 0.3 microns at 99.99% and are capable of removing all bacteria and some larger viruses. There are ULPA HEPA filters ( Ultra Low Particulate Air ) and SULPA  HEPA filters( Super Ultra Low Particulate Air ). These HEPA filters are normally used in Clean Rooms where the elimination of 99.99995% of all particles .01 microns and larger are required. To give you an idea of how small this is, your hair is about 100 microns in diameter. Also, you can only see down to about 20 microns with the naked eye. So .01 microns is very small. 

Over the past 30 years, HEPA filters have been incorporated into many air filtration devices and systems. Pure Air Systems, Inc. developed a fan powered, HEPA based air filtration system in 1985 that used the standard HEPA as its base filter. The company has seven different systems with air flows in the range of 50 CFM to 2,000 CFM. These are all metal housings using programmable variable speed motors that can compensate for the increase of static pressure across the HEPA filter and automatically maintain the required air flow for the applications. These are also capable of being operated by an app on your cell phone.

Indoor Air Quality A Real Problem In Residential Market

Over the past 15 years, the construction methods for building homes have created an indoor environment that can create health issues for the homeowners. 50 years ago most homes were built with little understanding of how their construction techniques were making the homes a breading ground for bacteria and viruses to grow. The homes were fairly air tight and the HVAC systems, in many cases, created stagnant air flow throughout the home. This meant that the air in the homes was constantly being recirculated with little or no fresh air being introduced into the living space. The filters used in the HVAC units and return air grills were ( and still are ) general duty air filters designed primarily to remove large particles and minimize the static pressure resistance through the HVAC ducting systems.

Today’s new homes are required to have positive pressure in the living space whenever the HVAC systems are on. This means, that when you open the door or window ( when HVAC is working ) the air should push out or flow out of the house. This means there is little to no fresh air being introduced into the home. Couple this with the fact that much of furnishings in our homes are now made overseas and there are some materials used in the fabrication of the tables, sofa’s, beds and bedding, etc. that can off-gas into the living space for a long time. These chemicals, along with airborne particulate from the use of these items, can create a very unhealthy environment. 

Pure Air Systems, Inc. has been making HEPA and Carbon based, fan-powered, commercial grade air filtration systems since 1985. For over forty years PAS has provided air filtration systems that can be attached to the return air side of any HVAC unit and bring in outside, filtered fresh air. Be bringing in even a small amount of air such as 100 CFM ( cubic feet per minute ), this can add up to 124,000 cubic feet of fresh air into the home every 24 hours meaning  all the air in the house is being exchanged 1.3 times every 24 hour cycle. This helps to keep the home environment safer and cleaner for its occupants. It also helps to dilute the amount of gaseous pollutants that are always present in most homes.

Use of Activated Carbon for Odor and Gaseous Pollutant Removal

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.

How Tariffs Affect US Manufacturing

The advent of the new tariffs being applied to a number of countries by the new administration are significantly affecting the US manufacturing complex as many parts, assemblies, products, chemicals, clothing and retail items come from outside the U.S. These additional costs, in many cases, can not be absorbed by the US companies so the extra costs are passed along to the consumer.. These additional costs, along with the current rate of inflation, have proven to be a real burden on the American public. Food prices are also at a all-time high and the rise of imported food products is part of that issue.

For companies like Pure Air Systems, Inc, that manufacturing high end fan powered, HEPA based air filtration systems, the additional cost of importing their HEPA filters and some of the electronic components for their remote controlled systems, has created a challenge. While PAS, is a highly specialized company, their customer base, of which 50% are retail customers, are somewhat hesitant to pay the higher prices for their systems. The commercial customers are still buying but waiting longer to make purchasing decisions. 

The high end, commercial grade HEPA filters are currently coming from Turkey, and they meet the specifications and delivery time for the PAS production process. Going back to a US vendor would delay production as going back to a US supplier would require renegotiating the purchase and delivery time table. 

The other issue, is the length of time these tariffs may be in place. Part of the rationalization for the tariffs is bringing manufacturing back to the US. However, as we have seen, this is very difficult to do and there are few companies with the capabilities to match the in-place production facilities that now exist everywhere in the world.

Still Crazy After 40 Years

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.

New Import Tariffs To Change The Playing Field

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.

Using PAS Systems As Fume and Fine Dust Collector Collection Systems

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.

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.

Air Quality In Your Home Is Very Important For Good Health

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.

The Arrow of Time Theory

In essence, the Arrow of Time Theory states that we tend to look at future technology and processes by carrying things from the past and putting them into these future ideas and concepts. This is very limiting as it tends to eliminate advanced or out of the box thinking with the resulting new concepts having parts of our old thinking linked with them. This type of thinking is doomed for failure.

Today, the advancements being made in AI, Robotics, Additive Manufacturing, Electric Cars, and Space Exploration are changing and will change forever the way the world works. These advancements are, in part, designed to minimize or eliminate the use of human labor is areas where the work is dangerous or the ability to significantly reduce the amount of labor needed to do menial tasks. Electric cars area already making major inroads in the global market and AI is now being used in almost every facet of design, marketing, product development , medical and governmental operations. 

While many people worry about the speed of change, these new concepts and technologies will actually speed up both the speed of change but also the adaption of these new technologies. This is necessary for our civilization to thrive and survive.
