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.

Mold is a common growth material that is normally found in damp environments or where there is little light or heat and there is the presence of water. When the mold spores the spores become airborne and for many individuals this organic material can cause severe reactions and respiratory dysfunctions. 

Mold spores are relatively large so they are easily captured by high end filtration systems such as HEPA filters or Merv rated filters of 17 or higher. These filters are much denser and can capture a very high percentage of the airborne mold spores. It is, however, important to know that you need to keep the HVAC fan running continuously if you want to pull the airborne spores back through the return air grills to the air filters.

Pure Air Systems has been making commercial based HEPA air filtration systems that are fan powered and include prefilters and carbon media. These systems are made from mild steel and are powder coated for use in all types of environments. These units range in capacity from 50 CFM for the portables up to 2,000 CFM for the larger systems. All of these units utilize variable speed drive motors and can be controlled digitally.

The PAS systems are used in the institutional, medical, industrial and residential markets to handle a wide range of airborne contaminants and are considered some of the best air filtration systems on the planet.

While this subject has been addressed once before, it is important that people understand the stark differences between the two types of air purification/filtration systems. 

First, UV ( A,B or C ) is purely a type of wave length of light that has certain affects on a variety of materials, both organic and inorganic. The UV rays from the sun, for example, have a significant affect on carbon, plastics, and the human body. While the UV rays can destroy some airborne contaminants, the amount of time ( in minutes ) the contaminants are exposed to the UV rays determines the efficacy of the process. In essence, UV only works if the UV rays are in contact with the air stream for an extended period of time. 

HEPA filters are a mechanical device that captures airborne particulate ( down to under 0.3 microns and smaller) at an efficiency of 99.99% and greater. This is important as even organic particulates that are destroyed can create issues once inhaled into the lungs. 

One reason UV is often used in-lieu of HEPA filters is the overall cost of UV versus HEPA filters. Also, the use of HEPA filters requires an auxiliary fan source as HEPA filters have a very high resistance to air flow and in order to pull enough air through the filter media requires a motor/blower assembly in addition to the blower assembly that comes with all HVAC systems.

Pure Air Systems offers a complete line of fan powered air filtration systems to meet the needs and demands of any residential or commercial application requiring the reduction and/or removal of airborne contaminants and also odors and gaseous pollutants.

For many years carbon media or expanded carbon, has been used for the reduction and removal of organic and inorganic gaseous pollutants. Expanded carbon or charcoal is produced using heat under high pressure that creates a surface area that has thousands of tiny openings that are capable of adsorbing gaseous molecules much higher in weight than the carbon itself. 

While carbon granules are often used in liquid filtration, the most common use is in air filtration whether in a stand alone filter or fan powered air filtration system. Carbon media filters have a fair amount of resistance and are therefore more often used in conjunction with a fan powered unit. 

Even though the expanded carbon has a high adsorption rate to weight of the carbon media, it will, over time, load up and stop adsorbing the odors or gases. Replacement cycles can be as long as once every 6 months to once every 6 weeks depending upon the severity of the gaseous pollutant.

The use of air filters for removing airborne particulates has been around for over 100 years. Today’s filtration technology is eons ahead of just using cheese cloth to filter our particles for fan powered device. The newer, blended filtration medias are much better at capturing small, sub-micron particles with higher capture rates and lower pressure drops over time.

Air filters range in efficiency from general duty, like furnace filters, to high capacity, high efficiency, like HEPA filters. For most home applications the general duty filters are used as they both help keep the cooling coils in the HVAC system clean as well as minimize the dust in your home. 

The higher efficiency filters, like HEPA, are used mostly in commercial applications like hospitals, clinics, surgery suites, chip manufacturing, clean rooms, laboratories and more. There are also HEPA based systems available for the residential market that utilize their own fan/motor system to augment the blower/motor assembly in the HVAC unit. HEPA filters have a much higher resistance to air flow but can capture particles as small as a virus. 

It should be noted, that the use of non-mechanical filtration devices such as ozone generators or electronic air cleaners are not really that effective at removing particles from the air. Ozone generators are really more effective on the reduction of airborne gaseous contaminants and electronic air cleaners need constant cleaning to make them work.

Innovation is a word that is often over used in today’s market place. Some new ideas or concepts are just an alteration to an already existing product that is being labeled “innovation.” 

In I985, Pure Air Systems was formed and it introduced some new concepts in fan powered, HEPA air filtration systems for both the residential and commercial markets. With an All-American made system, Pure Air Systems ventured into the air filtration market with a commercial grade, high performance, true HEPA filtration system that could be used in a wide number of applications, both residential and commercial. Initially, the PAS line of filtration units was limited to one model, and it incorporated the standard GE Induction motors and no bells and whistles.

By the 1990’s PAS had developed 5 additional models varying from the new HPS Portable line to the very large 2000 CFM 2000HS Plus unit. These new units were now using the new variable speed drive, ECM type motors that were rated, 120/240 Volt, 50/60Hz. This provided systems that could be used anywhere in the world. In addition, the new motors could be used with digital variable speed controllers offering customers the ability to adjust air flow and power performance to meet any performance specifications.

Today, Pure Air Systems is one of only 3 companies in the world that produce this type of commercial grade, high performance HEPA based air filtration system.

Indoor Air Quality has been an issue for enclosed spaces, homes, office buildings, medical facilities and industrial buildings since the early 70’s. The issues of people suffering from a wide range of health issues, mostly respiratory in nature, became more acute once the building industry started to build tighter buildings that offered little or no outside air intrusion. This process reduced the energy costs, but increased the amount of stale air and concentrations of gaseous pollutants and airborne particulate that are generated from most materials, chemicals, plants, animals and manufacturing processes.

Using only recirculating air through the air handlers and HVAC units and not allowing any outside, fresh air increased the IAQ issues. Adding outside air only added to the amount of particulate already present in the occupied space.

Pure Air Systems, based in Indiana, had developed a variety of commercial grade, fan powered, HEPA filter systems that could be used to both filter the air in the space as well as add small amounts of filtered outside air. By only adding 50 CMF to 100 CFM of outside air through the PAS units, one air handler could introduce up to 6,000 CFM of fresh, filtered outside air every hour and adding that to the recirculated air also being filtered, created a much healthier environment and reduced the amount of headaches, and respiratory issues in most residential and commercial operations.

Adding the small amounts of outside air, even on hot and very cold days, had a minimal affect on the amount of energy required to heat and cool the indoor environment. By adding an actuator to the inlet damper, it is possible to modulate the amount of outside air so that more or less air could be introduced depending upon weather or the conditions in the occupied space.

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.

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.
