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.

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.

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.

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.

In less than one year, the adaption of AI is not used in almost every facet of our lives. There is no industry or service business that is not using one or more of the AI programs that are being added to and updated daily. In fact, if your business is not incorporating AI into its operational profile it will fall behind its competitors very quickly.

For many people the use of AI has created visions of a massive take-over of our lives by some super intelligent machines. ( In truth that has already started). This belief is held mostly by older Americans who have a minimal understanding of technology and the vast knowledge base held in the Cloud. Change is always difficult for some people but the younger generation adapts quickly and they are using AI almost daily.

But AI is also being used in the engineering, design and product development arenas and this is where the real advantages are taking place. The use of engineering AI programs has tripled in the last year and the benefits have been amazing. Companies now know that they can use AI programs to accelerate their prototyping and product to market development process.

Pure Air Systems opened its doors in 1985. The use of any type of digital technology was limited to crude computer systems and reams of paper tape. All of the information gathered came from human sources and books. Designing a new filtration system took months and a fair amount of trial and error. All in all, it took 8 months to a year to develop a new product or modification to an existing system.

Today, adding a new product or modification can take as little as 1 to 3 months to complete, and the information is derived from the digital world. This adaption of digital information and/or AI is a necessary part of using technology to make us more productive and better our lives. It is important to realize that everything changes and change is constant.

People that are either building their first home or third home are always concerned with the interior room sizes, placement of rooms, wall treatments and appliances needed to make their home comfortable and livable. Unless they have had heating or cooling issues with an existing home, people rely on their contractor to put in the adequate cooling and heating systems and seldom think about the air filters or air filtration systems installed in a new home.

Most new homes are much tighter ( in regards to air leakage ) and a positive pressure door test is usually done to ensure that when the HVAC system is operational the home is slightly positive. Meaning air is being pushed out rather than being sucked in. Air filters are normally placed in the air returns that are normally located in most rooms, except the bathrooms. These general duty pleated filters are designed to keep most large airborne dust from entering the HVAC system and have very little resistance so they don’t put a strain on the main blower/motor assembly of the air handler. 

Since the air handlers are designed for the general duty air filters, placing a more restrictive, yet more effective air filter media, in the returns will reduce the fan power and pull less air through your HVAC system that could significantly affect the performance of your HVAC system. Therefore, you need to talk to your contractor prior to putting in your HVAC unit if you want to incorporate a more effective air filter system.

Usually the HVAC contractor will caution you about putting the more restrictive filters in your system and suggest a main air filter unit ( either electronic or media filter ) at the inlet to the air handler itself. This can be difficult and often creates installation issues and accessibility to the unit for servicing.

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985 and has developed a method of attaching one of their HEPA Shield units in a partial by-pass installation that allows the filter to pull anywhere from 600 CFM to 2000 CFM of air through the air filter and then putting back into the HVAC unit. By pulling only a portion of the air the HEPA Shield unit can clean all the air in the house from 24 to 48 times a day depending upon the frequency of operation of the HVAC unit. And, you can still place the general duty filters in the air returns.

If you live in a part of the country where the summer months bring high humidity along with the heat, then your indoor living environment needs adequate air conditioning to maintain healthy living. 

High amounts of humidity (moisture) will condense out on cold surfaces and can become a breading ground for mold. If the moisture gets into a crawl space or attic area that is not conditioned, this area can also be a potential place for mold to grow. 

Aside from efficient air conditioning, the home envelope should be under positive pressure. This means that when the HVAC system fan is running, the air pressure inside the home should be slightly higher than the external air pressure. This ensures the home will always be expelling a small amount of air and keeping outside moisture, heat and humidity from entering the home. If the home air balance is not correct, the negative affect of outside air intrusion into the home will far outweigh a good heating/cooling system.

In addition, good filtration should be part of your HVAC system. Whether you use good filters on the return air grills or a good media filter at the fan unit, filters can significantly minimize the levels of airborne dust and the potential for mold build up on interior surfaces.

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.
