Smoke, no matter how it is generated, is made up from very tiny particles that usually have a sticky or tacky component to them. This tacky substance will stick to any surface and then release the smoke odor for a period of time. This is why you have that smoke odor on your cloths after being encased in smoke from a grill, wood fire or cigarette. Smoke is perhaps the most difficult of airborne contaminants to remove due to these issues. The tacky material clogs up the openings of most particle filters and unless you are using an open mesh filter media which has virtually no capacity to collect much if any of the smoke particulate.

In order to remove a very large percentage of the smoke particles and help reduce the odor that continues to release from the smoke coatings, you need to utrase a multi-stage filtration unit. This would include a prefilter ( medium duty air filter ) carbon adsorption material and a HEPA filter. These three stages are used in commercial applications where smoke removal is required. This type of system design is not often used in the residential market but it is available for homeowners from Pure Air Systems, inc.

PAS has been making commercial grade, HEPA based, fan powered air filtration systems since 1985. These units come in a metal framed housing and use variable speed controlled motors that can be operated remotely with an app. The systems come in a wide variety of sizes and air flow capabilities from 50 CFM up to 2,000 CFM. They can be attached to an existing HVAC system or use as stand-alone units.

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.

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. For more information on these units please go to our website at:  http://www.pureairsystems.com  or call use on our toll-free number at:  800-869-8025.

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.
