It has always been a challenge trying to stay healthy while traveling in large groups, going on vacation and being cooped up with hundreds of people on a plane or thousands of people on a cruise. You always find friends and neighbors who have jus t returned from a trip only to have some kind of bug. This is why more people wear masks when traveling in confined quarters with lots of people for extended periods of time. 

On planes and cruise lines, the cabins have little or no real air filtration systems other than light duty filters to keep the air handling equipment clean. The removal of airborne allergens and pathogens is not accomplished by these filter systems and the tiny viruses that are floating around the airspace you occupy are breathed in continuously. This is how colds, flu, and other respiratory infections occur. Your bodies immune systems cannot always protect you from catching one of these illnesses.

In hospitals, surgery suites, micro chip manufacturing, clean rooms and any manufacturing application where keeping the air very clean the only type of filters that are used are HEPA filters. These highly efficient, somewhat expensive, media filters are specifically designed to remove up to 99.995% of all particles 0.3 microns and larger. There are a variety of these HEPA filters that have even better particulate capture rates with some up to 99.99955 of all particles 0.1 microns and larger. 

To give you an idea of micron size range, your hair is about 100 microns in diameter. You can only see down to about 20 microns with the naked eye. Viruses are as small as .001 microns in size. The standard duty air filters you use in your home are designed to capture large particles only and do almost nothing to remove the more harmful sub-micron airborne viruses. 

Pure Air Systems has been making HEPA based, fan powered, commercial grade HEPA based air filtration systems since 1985. They are one of the leaders in high volume stand alone HEPA filtration systems using programmable, variable speed motors for finite control of air flow and particulate capture. These systems range in air volume from 50 CFM to 2,000 CFM with the ability to control air volume in 1% increments. These units can be used as stand-alone units or attached to existing HVAC units, are designed for commercial, industrial, institutional and residential applications.

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.

No matter how you may feel about the Covid virus issue, there is a new variant that is quickly moving through the US. Viruses will mutate rapidly to stay viable even though there are a number of vaccines now available for the general public. One of the major reasons these viruses stay active is the fact that people that have this virus and are coughing or sneezing and they often mis-diagnose this as a cold or allergies or sinus issues. So, they continue to congregate with other people at work or school and the virus spreads faster.

Pure Air Systems has been making high end, commercial grade HEPA based air filtration systems that are specifically designed to remove bacteria and a high percentage of viruses. Viruses are extremely small and are impossible to capture with general duty air filters. HEPA filters are designed to capture 99.99% of all particles 0.3 microns and smaller. These particle sizes are invisible to naked eye so it is impossible to see them when they are airborne. 

PAS make a wide range of sizes and air flow capacities for any application. The fan powered units can be used either as a stand-alone unit or attached to an existing HVAC system. The systems can move anywhere from 50 CFM to 2,000 CFM depending upon the requirements. Also, these units use variable speed drive motors with speed adjustments from 1% TO 100% in 1% increments. And, they can be adjusted from an app on your phone. PAS also makes a small portable unit that can be taken with you in you car if you travel and stay at a hotel or motel and are visiting family members.

Tesla has been incorporating true HEPA filters along with standard filters in all of their cars and the Cybertruck. These are installed as a method of both keeping hazardous particulate from entering the interior of the car and maintaining an allergy free environment. They even have a setting in case there is a nuclear incident where the car maintains a sealed off interior from exterior elements. 

HEPA filters have been around for many years and were first developed during the initial phases of creating the bombs used on Hiroshima. These specially designed filters utilize a special wet – layed paper like material that is extremely dense. It is then folded into an accordion style format to allow for greater filter surface area in a small envelope. Most HEPA suppliers use either aluminum or glues to keep the pleats separate and rigid. These HEPA filters come in various sizes to fit a wide variety of applications including medical, chip manufacturing, clean rooms, surgery suites, pharmaceutical manufacturing and some food processing applications.

HEPA filters are relatively expensive and usually come in a metal frame or stiff cardboard frame for some applications. The Tesla HEPA filters use a stiff paper frame to allow for some flexibility in inserting the HEPA filter into the appropriate slots. The normal life of the HEPA in the Tesla is approximately two years as the HEPA is preceded by a general duty filter to keep the HEPA clean and only allow the very tiny particles to enter the HEPA.

Pure Air Systems has been manufacturing HEPA filter systems since 1985 and is now only one of three companies in the world that make a fan powered, commercial grade HEPA system that includes prefilters and carbon media along with the HEPA. These units range in air flow capacity form 50 CFM to 2,000 CFM and use variable speed drive motors that are programmable and can be operated remotely from a phone app. For more information on the complete line of HEPA systems please go to our website at;  http//:www.pureairsystems.com  or call us on our toll free number at:  800-869-8025.

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.

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.
