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.

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.

A very large number of appliances and motorized equipment that we use utilize electric motors. Some are very tiny and they run small appliances and consumer products like 3D Printers and grinders. Most of these are induction type motors that may have some form of speed controller or are just on/off motors. And, many of them are designed for single voltage use, meaning they are either 120 volt 60 Hz or 240 volt 50 Hz ( like those in Europe ). 

In 1998 General Electric developed a new motor that incorporated a magnetic drive system as opposed to a copper wound motor. These new motors could run forwards or backwards and would operate on 120/240 Volt 50/60 Hz current. First, this allowed them to be used any country in the world and secondly opened the door for development of a wide variety of new devices for many equipment manufacturers. 

In addition to being able to run in both directions, they could be controlled to run at increments of 1% to 100% in 1% increments making them extremely viable for applications where finite speed control was required. In addition, these motors can now be programmed to speed up or slow down based upon the performance requirements of the equipment. For example, if the motors are being used on systems that require different speed profiles for various performance requirements. These new motors can now also be operated by using a App on your phone so they can be controlled from any distance as long as there is wifi available. 

Pure Air Systems, an Indiana based corporation, has been using these new motors in their HEPA based, fan powered air filtration systems since 1999. PAS was one of the first companies to incorporate these motors into their systems replacing the standard induction motors. The new motors provided an entry into the European market and created an entirely new market for these air filtration systems. They could now be used both attached to existing HVAC systems with the ability to match the airflow requirements and also as stand-alone units where air filtration was needed in non-conditioned space.

Pure Air Systems was founded in 1985 with the specific intent of bringing commercial grade HEPA based air filtration systems to the residential and industrial markets. Over the years PAS developed 7 different system configurations that could either be attached to an existing HVAC system or used as stand-alone units. 

Over the years PAS has improved its air filtration systems by incorporating programmable variable speed drive motors that can now be operated with an app on your cell phone. This allows for infinite air flow adjustment for best filtration efficiency and performance. This process provides a unique advantage of using the PAS line of HEPA filters over all the other competitors in the market. In fact, Pure Air Systems, Inc, is one off only 3 companies in the world that make this type of air filtration system.

The PAS HEPA systems use all metal housings and can incorporate a variety of filter types in their units. These include the scanned 99.995% HEPA filters, carbon media filters and ring panel pre-filters. The system range in air flow capacity from a low of 50 CFM up to 2,000 CFM for the larger units. The systems can be used strictly as odor or gaseous removal systems by using just the pre-filter and carbon media filters without the HEPA. This makes these systems extremely flexible as they can be modified in the field with different filter arrangements in a matter of minutes.

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.

It is virtually impossible to not see some form of AI agent being used in every social media platform and advertising process today. Most companies now use some form of AI software to enhance their operation and find a way to stay ahead of the competition and to enhance the performance of their current work force.

Adapt or die used to be a term used many years ago as new technology and the internet came into play, and you had a few years to play catch up. Today, Adapt or Die is a very real issue. By the end of 2026, there will be new processes used by every company in the US and around the world that will forever change the way we look at human functions. AI is a tool that can be used by people in both first and third world countries. It has no boundaries and it’s ability to modify, change or alter it’s programming independent of human input. It will just keep getting better and more human like it is operations. 

AI is now directly tied to autonomous driving cars and Humanoid Robots. These technologies are improving almost weekly and the adaption of autonomous driving is increasing daily, globally. Robotics is now at a point where Robots will start taking the place of workers in factories and eventually add to or remove many jobs in the service sector, including medical.

Pure Air Systems, has been manufacturing HEPA and Carbon based fan powered air filtration systems since 1985 and they are now adding AI to their marketing programs to help continue their presence in a very niche oriented market place. They offer a complete line of HEPA based filtration systems ranging from 50 CFM to 2000 CFM.

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.
