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.

It has been repeated many times online and in articles in every type of publication that we tend to not become fearful of things we can not see. And yet, the biggest challenge we have as humans is the transmission of airborne viruses that affect everyone multiple times in their lives. From the yearly Flu bug to Covid 19 and the Common Cold, all of these airborne viruses are constantly searching for a warm host to stay alive and grow.

For many of the airborne viruses there are anti-viral shots available to either eliminate your chances of getting it or minimizing the symptoms if you do get sick. For some reason, there are a number of groups ( all non-medical ) that constantly provide warnings about the various bad side affects of getting injections for all types of viruses. This has created a huge problem for the medical industry as more people are getting sick and in many cases requires them to be hospitalized. In many cases these anti-immunization groups even target mumps, measles and now polio. 

Yes, viruses are extremely small and not visible with the naked eye, but they can be and are significantly reduced or eliminated using filters such as HEPA and SULPA filters. These filters capture airborne viruses and are used in medical facilities around the world. Some of these HEPA systems are available to homeowners and small businesses here in the U.S. Since Covid, the increase use of these type of systems in commercial and institutional environments has doubled. However, with the public continuing to deny the value of anti-virual serems, the challenge to the public will continue to grow.

Pure Air Systems manufactures a line of HEPA and Carbon based, fan powered air filtration systems. These range in capacity from 50 CFM to 2000 CFM.

People that are either building their first home or third home are always concerned with the interior room sizes, placement of rooms, wall treatments and appliances needed to make their home comfortable and livable. Unless they have had heating or cooling issues with an existing home, people rely on their contractor to put in the adequate cooling and heating systems and seldom think about the air filters or air filtration systems installed in a new home.

Most new homes are much tighter ( in regards to air leakage ) and a positive pressure door test is usually done to ensure that when the HVAC system is operational the home is slightly positive. Meaning air is being pushed out rather than being sucked in. Air filters are normally placed in the air returns that are normally located in most rooms, except the bathrooms. These general duty pleated filters are designed to keep most large airborne dust from entering the HVAC system and have very little resistance so they don’t put a strain on the main blower/motor assembly of the air handler. 

Since the air handlers are designed for the general duty air filters, placing a more restrictive, yet more effective air filter media, in the returns will reduce the fan power and pull less air through your HVAC system that could significantly affect the performance of your HVAC system. Therefore, you need to talk to your contractor prior to putting in your HVAC unit if you want to incorporate a more effective air filter system.

Usually the HVAC contractor will caution you about putting the more restrictive filters in your system and suggest a main air filter unit ( either electronic or media filter ) at the inlet to the air handler itself. This can be difficult and often creates installation issues and accessibility to the unit for servicing.

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985 and has developed a method of attaching one of their HEPA Shield units in a partial by-pass installation that allows the filter to pull anywhere from 600 CFM to 2000 CFM of air through the air filter and then putting back into the HVAC unit. By pulling only a portion of the air the HEPA Shield unit can clean all the air in the house from 24 to 48 times a day depending upon the frequency of operation of the HVAC unit. And, you can still place the general duty filters in the air returns.

Our eyes allow us to focus on and see airborne particles as small as 20 microns. For comparison, the human hair is about 100 microns in diameter. Most bacteria are in the range of less than 1 to 5 microns in size and viruses are less than 0.12 microns in size. So the old adage that what you don’t see won’t hurt you is not correct.

Bacteria, when present in a warm, moist environment, can stay alive for very long periods of time. From many hours to days. Because it is heavier than viruses it will not stay airborne for very long. So most contact with bacteria comes from contact with a surface or body part that caries the bacteria.

Viruses, on the other hand, are very tiny and light and can stay airborne for long period of time. This is how the flu and cold bugs are normally transmitted. Coming in a room or close contact where these viruses are airborne can infect another human once the viruses are inhaled and ingested. This is the reason masks are used in all medical facilities, especially surgical units.

In a time when social media dominates the world of news, content and data, it is more important than ever to use other sources of information as well. Often, individuals will look to a certain media type, group or organization to obtain information on a product, process, person or location. For the most part, this information source is typically skewed toward feeding incorrect information or biased information for self-serving issues.

It is amazing how few people actually go directly to the companies website or information pages to gather data. While companies do tend to hype their own products or processes, for the most part the information is usually very accurate. 

Pure Air Systems manufactures a complete line of fan-powered, commercial grade, HEPA based air filtration systems for both the commercial and residential markets. PAS is now 37 years old and is one of only three companies in the world that makes this type of high end filtration system. And, almost all of the components are made right here in the US. 

In order to provide factual information about their systems, PAS inserted a large number of pages dedicated to providing information on the operational capabilities and effectiveness of all types of air filtration and purification systems currently available on the market. This is called. Pure Air University, and it is a really good primer on explaining in plain English, how mechanical and non-mechanical air filtration and gaseous pollutants are effectively removed or reduced.

It is interesting how many people will rely on alternate sources of information that are completely counter to the factual data provided by the information on Pure Air University. This is one of many reasons why companies struggle against the social media tide that washes over their factual data.

Smoke from cigarettes and cigars is highly visible and has a distinct odor. It is pungent and will stick to any surface and re-release the odor for a long time. It will cling to clothing and stain hard surfaces over time. Of all the airborne contaminants we generate, cigarette smoke is the most difficult to remove from the air.

Smoke from cigarettes and cigars has both a particulate component and an odor component. Both difficult to capture using filtration systems. The odor can only be removed using carbon based media and the cigarette smoke will even plug up a HEPA filter over time.

The use of ozone generators or UV lights also do very little to alleviate this situation indoors and it is now  the reason smoking is prohibited in almost all indoor facilities, restaurants and eating establishments. It is just too difficult to mitigate with almost any filtration technology.

Pure Air Systems has been making high end, HEPA based, fan powered air filtration systems since 1985 and one of only three companies in the world that make systems for both the commercial and residential markets. The systems range in capacity from 50 DFM to 2000 CFM and can include a prefilter, scanned HEPA filter and carbon media. The systems now all use variable speed drive motors and are digitally controlled. The units are also capable of being used in 120/240 50/60hz applications.

For the majority of the U.S., Summer represents hot days, hot nights and in many parts of the U.S., high humidity. This means that for the most part people will remain indoors in their homes, offices and shopping areas in the presence of cool, air conditioning. 

While air conditioning keeps the interior space cool and removes the majority of the humidity, the lack of any outside fresh air means that all the air in the home, office, school or shopping areas is stagnant or stale. Without any type of effective air filtration, the levels of airborne particles (which can include, human skin, bug matter, airborne dust and debris of all types) will increase 10 fold. And, if there are animals present, then the potential for high concentrations of animal dander may occur.

In order to minimize the health hazards of breathing stale, polluted indoor air for long periods of time, we recommend using good air filters on your returns or consider putting one of our 600HS Plus HEPA systems on your ducted forced air HFAC system. With the unique partial-bypass installation concept it is possible to filter all the air in your house up to 24 times per day and introduce a small amount of outside, filtered fresh air without upsetting the AC temperature and humidity in your home.

There are some songs that seem to transcend time and this one by Eric Burton and the Animals is not exception. For almost anyone alive today hearing the first 5 cords of this song instantly remind you of what comes next. There are products and companies that also fall into this category.

Pure Air Systems, Inc. Founded in 1985, is one of those companies. PAS was one of the first companies in North America to offer true HEPA based, fan powered, air filtration systems for both residential and commercial applications. The model 600HS was the first HEPA system that was designed to attach to any forced air, ducted HVAC system using the partial by-pass concept. This allowed the use of the 600, 1200 and 2000HS series units to used in any application for any size HVAC unit with the added ability to introduced fresh, filtered outside air in small quantities to help pressurize any environment.

Today, Pure Air Systems is one of only 3 companies in the world that produce this type of commercial grade HEPA air filtration system. These units also use the variable speed drive motors and can be programmed to adjust the speed ( air flow in CFM ) to suit the application.

Many products that used to be fabricated from metal are now made by using an injection molding process and a wide variety of plastics to keep the cost and weight down. In many cases this option works as the strength of many of the composite plastics are very strong and will work for most applications.

In 1985 Pure Air Systems began its process of making fan powered, commercial grade, HEPA air filtration systems for both the residential and commercial markets. The cabinets used to house the filter components was mild steel that was powder coated. These rugged housings allowed for the use in both interior and exterior applications and provided a housing structure that would last 20 years or longer under heavy use.

The housings ranged in size from the small portable which is approximately 13 inches square by 21 inches long, the 600HS series which is 16 inches square by 34 inches long ( high ), The 1200 HS series which is 25 inches square by 48 inches long and the 2000HS series which is identical to the 1200HS in size. All of these units are fabricated from 16 gauge powder coated steel and are built to last.

Early in the 90’s. Pure Air Systems looked at the possibility of using strong, composite plastic materials in-lieu of metal housings but found both the cost and challenge of making a unit strong enough to hold the metal blowers, ECM motors and HEPA filter and associated prefilter material. In this case, metal was and has always been the best choice for making the high performance HEPA based air filtration systems.

HEPA filters were developed in the early 1940’s during the creationg of the atomic bomb.The use of radioactive materials in the making of the bomb created extreme health hazards for the technicians and engineers that had to handle this type of material. Due the extremely small size of the radioactive particles ( Sub-micron in size ), readily available air filter media like furnace filters, were totally useless in reducing the levels of radioactive particulate. They needed a filter material that could absolutely remove and capture these tiny particles. 

After trying a number of materials a process using a wet laid paper type material infused with tiny pieces of glass was used to develop a very dense material that was capable of filtering out these tiny sub-micron particles. The paper like material was formed into an accordian style form with pieces of aluminum sandwiched beteween each folded layer to protect the paper-like media as it was relatively fragile and could abrade by rubbing on itself.

The filter pack was placed inside a square medtal housing and was glued in place. The outside parameter of the metal housing had a neoprene type gasket so when it was placed in a sheet metal duct it would compress the gasket to form a leak-tight seal. These filters had an initial efficiency of capturing 99.97% of all particles 0.3 microns and larger and as it got dirtier its efficiency increased. The use of this HEPA filter allowed the technicians to work in a safer environment culminating in the eventual creation of the two bombs used on Japan to end WWII.
