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.

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.

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.

Carbon that is used for odor control if often made from expanded cocoanut shell carbon. This type of carbon has a high surface area and very high ratio of molecular adsorption to weight of carbon. This makes this material suitable for both adsorption of organic and inorganic odors and gaseous pollutants in both air and water applications.

For general odors found in most homes; typically pet, cooking and carpet odors, carbon filters placed in the HVAC system will be capable of removing about 50% of those odors with a replacement cycle of once every two months.

For commercial and industrial applications, it may be necessary to use large carbon beds, 10 – 20lb pads of carbon, to significantly reduce the the gaseous pollutants. And, in some cases, a catalytic material like zeolite may be required to enhance the adsorption of the gaseous pollutants. Depending upon the amount of pollutant being released it may be necessary to replace these carbon pads as often as once a week. 

Odors such those produced by cigarettes are some of the most difficult to remove as the nicotine smoke produces a sticky residue with adheres to almost any surface and releases that odor for long periods of time. Carbon can help in these cases but replacement of the carbon can be up to once a day.

Founded in 1985, Pure Air Systems was one of the first companies to introduce true, commercial grade, fan powered HEPA air filtration systems. The first unit, model 600H, was the base model using a standard 120 volt, 60Hz GE motor, Lau blowers, scanned HEPA filters, carbon media packs and ring panel pre-filters and switches and wire harnesses. All American made. 

Today, Pure Air Systems has 5 different models ranging from 50 CFM to 2000 CFM using the same metal housings, HEPA filters, carbon media packs but with the new variable speed 120/240 volt 50/60HZ motors, digital controllers and pressure gauges. Again, all of these components are currently being made in the USA. In addition, PAS is now one of only three companies in the world that manufacture these commercial grade HEPA air filtration systems.

Making products using US made components in today’s world creates some unusual issues. With most companies using components made in China or other overseas countries, competing with US made components is becoming more difficult. However, the Pure Air Systems units historically have a 15 to 20 year life cycle even in heavy duty operations. The cost may be higher but the performance is unmatched when comparing to similar products made in China.

In the 60’s Eric Burton of the rock group The Animals sang a song about a lost soul. The name of the song was Tobacco Road. The animals and song went on to become an iconic part of early rock and roll. Along the same lines the product tobacco had also become one the most influential soft drugs in the US and around the world. Nicotine, one of the main components of cigarettes and other tobacco related products, is also one of the most addictive compounds legally allowed in every country in the world.

In addition to the nicotine that is harmful to the user, the cotinine that is released as a result of burning the nicotine is a sticky material that sticks to everything it touches and releases an odor that lingers for a long period of time. Attempting to remove this airborne gaseous compound is difficult as it requires both carbon for adsorption of the odor as well as filter media ( usually HEPA filters) to capture the very fine airborne particulates that are released by the cigarette.

Because of the nature of the two emissions both the carbon and media filters ( HEPA ) need to be changed frequently making it very expensive and challenging to remove cigarette smoke in a room or enclosed area. This is one of the major reasons whey smoking is now prohibited in almost every public building and most restaurants.

As everyone knows, being around smoke from a forest fire is extremely difficult and dangerous as smoke inhalation can be deadly. For California this past year, the forest fires have been nothing short of horrific. Many homes were lost and smoke hung in the air for weeks in many areas of California.

Pure Air Systems, an Indiana based company, has been making fan powered, HEPA based air filtration systems since 1985. Their systems are capable of being used either in conjunction with an existing HVAC system or as stand alone units. The partial by-pass configuration of the units allow for complete filtration of the home environment while also adding the ability to introduce outside, filtered fresh air to pressurize the home.

A homeowner in the San Francisco area purchased a PAS Model 600HS HEPA Plus system to do just that. His ability to bring in outside air through the 600HS unit and pressurize his home allowed him to stay inside and almost eliminate any smoke or odor from coming into his home. In fact, many of his neighbors also came to his house to escape from the smoke that was everywhere in the SF Bay area.

The 600HS unit has three filters. A dual layer ring panel filter to capture large particles and keep the HEPA clean, a 10 lb carbon filter to remove odors and a scanned 99.99% commercial grade HEPA filter to remove sub micron particulate. Pure Air Systems also makes larger versions of this filtration system ranging from 50 CFM to 2,000 CFM. These systems have been on the market for over 34 years and are the best performing HEPA based air filtration systems on the market today.

I am not a huge fan of the band Metallica, but I do happen to like their song, Enter Sandman. It is different than most of their Very heavy metal music and actually tells a story and your  can understand the lyrics. There are other bands whom I don’t follow very much but they, like Metallica, have one or two great songs that get lots of air time on the radio and are on my iPod.

Like my selective choice for music, when I am purchasing certain items I usually go to a certain brick and motor store or shop online where I will purchase that item. The stores may hundreds of other items but I only purchase those select, one or two, items every time.

Many companies that are in the manufacturing business may offer a number of items both standard and custom for customers. However, they often have 80% of their  business derived from 20% of their product line and while they often consider paring down their product line they find customers like the ability to option shop.

Pure Air Systems opened their doors in 1985. They introduced the first high performance, fan powered, certified HEPA air filtration systems for residential, commercial, institutional, medical and industrial application for removal of airborne allergens, pathogens, particulates and odors. Initially PAS only offered one system, the 600H unit. It became a very popular product in the U. S. market and led to the development of 6 more HEPA based systems.

These other units were more powerful and had larger CFM volume capacities and all eventually were fitted with the new ECM variable speed drive 120/240 50/60 Hz digital speed control motors. While the larger systems pushed PAS into the commercial market faster the model 600HS ( now with ECM motor ) was and still is the primary unit sold by Pure Air Systems.

The reduction/removal of airborne particulate is usually accomplished by the use of air filters or filtration systems. The filters may be installed in a ducted heating/cooling systems return air grill or as a stand alone unit that circulates the air in a specific room or building. These types of filter systems are the most effective as they allow for circulation of the air within the room and while keeping the room temperature and humidity levels constant.

On the other side of the equation is the use of pressurization to reduce particle levels and/or maintain a higher degree of fresh air in a room, building or environment. To pressurize any room or space you simply need to draw in or pull in enough air from an outside source to change the pressure gradient in the room from either negative or static to a positive pressure room. We can all identify with positive or negative pressure as seen when we enter a large building or office and when opening the door the air blows out into your face ( positive pressure) or you have some difficulty opening the door ( as it seems to be pulled away from you) and overcoming negative pressure.  Another way to identify positive or negative pressure in a room is to open the main door about 1″ and take some smoke or a piece of tissue paper and place it at the door opening. If the smoke or paper moves toward the opening the room is negative, if it moves out toward you the room is positive.

The use of positive pressure as a means of filtration or “room cleaning,” has some major drawbacks. First, the air you bring into the room would probably be from an outside source. Although in a large building you could pull air from any space in the building and pressurize the room but that air may be just as dirty as the air in the room you are attempting to clean. Therefore, using an outside air source for pressurization is usually better but is comes with some costs.

Unless you live in a part of the country or world where the daily average temperature is around 70 degrees fahrenheit  and the humidity is 40% or less, bringing in outside air to pressurize a room will substantially alter the temperature and humidity in the pressurized environment.  In order to use pressurization effectively you would need to introduce at least 30% outside air as it relates to the amount of air being heated or cooled in the room.  For example is you have a room that circulates and conditions 600 CFM through its heating/cooling system you would need to introduce at least 180 CFM of outside air to remove some of the  airborne particulates or contaminants.

This process is often used in smoking areas in bars and lounges and in locations where odors, gases or fumes are being generated and dilution by introduction of outside air is the least expensive alternate. The amount of air introduced from the outside would vary depending upon the type of contaminant as just mentioned. It may be that up to 50% dilution is required to effectively reduce the levels of contaminants, however, this large amount of air will displace half the air in the room so some form of vent is needed to allow the fresher air to come into the room and push the contaminated air out of the room. It will also significantly impact the heating/cooling/humidity levels in the room or space.
