While there are many small, battery or electrically powered air filtration units on the market, these tend to be utilized for small areas and with minimal air flow. In many cases they are made with plastic fan blades with very small motors and are useful primarily in a small space or room. These are sold through retail outlets and on Amazon. 

The commercial HEPA air filtration systems offered by Pure Air Systems, use all metal components for their housings, fans and motors. These units are designed to move anywhere from 50 CFM up to 2,000 CFM of HEPA filtered air. The variable speed motors used in these systems can be controlled remotely and the fan speed can be adjusted in 1% increments to meet any air flow demand for any size room or area. 

The PAS air filtration systems are designed to be used as either a stand-alone unit or they can be attached to the return air side of any ducted HVAC system. They can be used to introduce very small amounts of outside air to help pressurize a room to keep it in a positive pressure mode. The outside air is introduced before the filters so the air is completed filtered prior to entering the room or area.

The PAS units come complete with a prefilter, carbon media filter and true commercial grade HEPA filter. The units can also be configured to just have a prefilter and all carbon for applications where gaseous pollutants are present. The filters are easy to access and only available from Pure Air Systems.

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.

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.

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.

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.

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.

Everyday there is information provided regarding the level of outdoor air quality and it’s potential affects. The levels can range from good to very poor. While some people with severe allergies or respiratory issues value this information, most people pay little attention to these outdoor air quality warnings because most of us are indoors the majority of our time. Either at home or work or both. And we believe that being inside is much safer and healthier. And nothing could be further from the truth.

Indoor air quality is maintained, primarily, by the HVAC systems that both heat and cool the interior spaces. These systems recirculate the air with very little fresh air being introduced into the home or building creating a somewhat stagnant indoor air environment. The air filters that are used in most HVAC systems are general duty filters designed to capture very large dust particles that are airborne. These filters don’t capture bacteria, viruses or various forms of allergens. This means that all the airborne particulate are being recirculated throughout the interiors spaces for everyone and anyone to breathe. 

Most new homes are now designed so that when the HVAC units are running the home is under positive pressure, meaning no outside air is being introduced into the interior spaces. While this keeps the home warmer in the winter and cooler in the summer, the lack of outside fresh air creates a very unhealthy indoor environment. But there are solutions to this problem.

Pure Air Systems has been manufacturing HEPA and Carbon based, fan-powered air filtration systems since 1985. This US based company makes a line of systems that can be attached to the return air side of your HVAC unit and because they have their own fan assembly, they can be installed to introduce small amounts of fresh, filtered, outside air into the home or office. Since the HEPA filters are designed to capture bacteria and many types of viruses along with other allergens, The PAS units provide the perfect solution to keeping the air in your home or office clean and fresh.

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.
