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.

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.

Intel is investing $20 Billion dollars to build two state-of-the-art Micro Chip manufacturing plants in Albany, Ohio. Chip manufacturing is done in Class 10 and Class 100 clean room facilities which are constantly being cleaned by HEPA filters with the rooms being under positive air pressure.

Chips are comprised of multiple layers and then assembled together. These layers are highly sensitive to any airborne particulate, even in the sub-micron level, as the dust particle will destroy the chips function and short it out when in use. The types of HEPA filters used in the manufacturing and assembly areas are normally comprised of a series of HEPA’s in banks. They use HEPA, ULPA and SULPA HEPA filters that will remove 99.9999% of all particles 0.12 microns and smaller. As as comparison, the Human hair is about 100 microns in diameter.

Pure Air Systems has been providing commercial grade, fan powered, scanned HEPA filters ( 99.99% at 0.3 microns) since 1985. Many of these systems have been and are being used in smaller micro chip operations, medical facilities, hospitals, military and institutional plants. The PAS systems range from 50 CFM up to 2000 CFM and can include Carbon media along with a Prefilter.

The Chevy Nova was made in the early 60’s through part of the 70’s and was somewhat popular as a mid sized, low cost vehicle. This car also had many mechanical issues and was dropped from the line up only to be resurrected as the Chevy Citation in the 80’s. Different design, same issues. When the Japanese entered the US car market they were surprised that General Motors ad chosen the name Nova because in Japanese this word means NO GO. This should have been a warning to GM not to use that name.

When Pure Air Systems came out with their HEPA filtration systems in 1985, the units were considered too expensive and the existing furnace type media filters were considered the best filters on the market. Ozone generators and Ion Generators were also sold as high efficiency air filter systems and were much less expensive than the HEPA units. However, like the Nova, these general duty air filtration filters and mechanical systems did not work as promised and are still sold today to unsuspecting consumers. 

The fan powered, commercial grade HEPA filtration systems by PAS are considered some of the best overall HEPA systems on the market. And, Pure Air Systems, Inc. is one of only 3 companies in the world that make this type of HEPA system with a wide range of sizes and housing configurations. The PAS line offers systems that range from 50 CFM to 2000 CFM using new ECM variable speed drive motors.

No matter who you talk to today, many of the older people are saying we should only buy American made products. That, today, is easier said than done. First, many individuals that order on line ( and that is the majority of people) buy products that meet their needs at the best price and seldom search for its origin of manufacture. 

Pure Air Systems, Inc. has been manufacturing its fan powered, commercial grade HEPA based air filtration systems in the US from all US made components since 1985. Today almost 95% of all the components used in the manufacture of our HEPA Shield systems are made here in the U.S. And, since its inception in 1985, PAS has always put Made in the USA stickers on our filter cabinets.

Customers that are familiar with our systems are happy to pay the higher cost for the systems knowing that the quality of our systems will provide them with great air filtration for 15 to 20 years of service, with reasonable filter changes. and minimal maintenance, Over the years many of our customers purchased less expensive, made over seas products, but eventually came back to PAS because our systems perform so much better than 95% of our competition. In fact, Pure Air Systems, Inc, is now one of only 3 companies in the word that produce this type of HEPA based air filtration system.

With over 13 years of experience in using FDM and FFF 3D style printers one learns quickly the various quirks in the operation of these printers. While they have improved dramatically since the 2011-2012 introduction of desk top printers, there are still some challenges when printing with various filament types. To be specific, ABS ( Acrylonitrile Butadiene Styrene ) has been one of the more popular materials with which to print. However, this material off-gasses when printing at 245 Degrees C and above and the odor can be quite significant. In addition, the gases produced along with some of the fine particles released during printing can become a health concern if not properly vented or isolated when printing occurs.

One of the other issues when printing with ABS is the layer separation that can take place if the object being printed cools to rapidly during the printing process. To minimize this issue you need to enclose the printer and keep the cold air drafts from falling on the printer bed. This enclosure can also also double as a mechanism to reduce the entry of the odors and particulate into the room. The use of a fan powered exhaust system attached to a vent in the enclosure along with a carbon media and HEPA filter will allow for continued use of the printer inside any room or enclosed area without compromising the environmental integrity of the room.

Pure Air Systems has been making fan powered HEPA and Carbon medial filters since 1985. These systems are designed to move from 50 CFM up to 2000 CFM with the ability to control the air volume in 1% increments. These metal framed units come in seven different configurations with the addition of a portable unit that is a prefect fit for the enclosures that would be placed over the 3D printers.

I must say that I am getting tired of all these Twitter, YouTube, Instagram, etc. sites that tell me things like: “If you look outside and see that liquid falling from the sky….that is rain. And let me tell you why it falls the way it does.”  Really,? Have we arrived at point in our lives that we can only verify what we saw because someone else used social media and told us it was real? 

These are some of the reasons why companies and individuals who actually have valuable and reliable content on their websites and blogs dislike social media. They now have to shift to the “Bizzaro World” approach to get anyone to pay attention. If you are looking for real content then take a look at the Pure Air Systems website. A company that is now 36 years old and one of only three companies left in the world that make this type of fan powered, commercial grade, HEPA filtration system.

In early days of PAS, a lot of content was written for the site that provided easy to understand technical information about all types of air filtration systems, including those sold by competitors. This part of the site was titled:  Pure Air University. It is still a viable section of the website and often used by those searching for real, technical, information written in a format that is easily understood by the laymen. This data forms the basis by which all types and styles of filters are rated and is still one of the most widely read of all the data on the site.

Created in 1985 by Don Musilli, Pure Air Systems was one of many companies offering air filtration systems for the commercial and residential markets. But the separation from the competition began shortly thereafter. From the beginning, PAS used an all metal housings, Lau Blowers, GE Motors and commercial grade prefiters, carbon media and HEPA filters. The initial units sold for $695.00. Over time, PAS added other units to their line up and in 1998 became one of the first powered fan filter companies to use the new GE ECM variable speed drive motors. 

The addition of the new motors and expansion to a 9,000 sq. ft. building allowed PAS to expand their product line to 7 different size air filtration systems all of them now using the upgraded, digitally controlled variable speed drive motors. The ability for the motors to be 120/240 50/60 Hz created a new market overseas for the larger systems. The new HPS portable unit opened the doors to more medical markets and the Covid – 19 global pandemic created a whole new market for commercial grade HEPA air filtration systems.

Today, there are only two other companies in the world that make a fan powered, commercial grade HEPA air filtration unit handling up to 2,000 CFM and as low as 50 CFM. With material costs for metal and other components increasing rapidly, it is much more difficult for companies to offer products such as the ones from Pure Air Systems.

Air curtains are designed to be placed above a large door or opening to create an “air barrier” so to speak, that will keep the air from one side of the curtain from entering the other side of the curtain. This is accomplihed using a high volume industrial blower and fan with a fairly powerful motor. Usually 1/2 HP to 1HP. The air is produced by the fan and forced through manifold that is placed along the top edge of the door and extends the entire width of the door. The opening of the flow side of the manifold is very small in comparison to the air entry side of the blower. This design create a venturi affect that jets air downward at a very high velocity. 

Pure Air Systems has a series of fan-powered HEPA based air filtration systems that can be used as the main source of fan power for an air curtain while also maintaining a contaminant free air door. These HEPA air curtains are often used in food processing, medical product manufacturing, laboratories and medical facilities. The main advantage is the speed of entering or exiting a room without having to open or close a door. This is a real advangtage when the door opening is very wide and would require either double doors or a horizontal sliding door. In addition, you could have more than one person moving throught the opening at one time. 

Pure Air Systems has been manufacturing HEPA and Carbon based air filtration systems that are fan-powered and with all metal housings since 1985. These units range in air flow volume from a low of 50 CFM to 2,000 CFM. The PAS units come standard with a true, scanned HEPA filter, Carbon Filter and Prefilter. All components are made in the USA.

Asthmatics suffer from airborne allergens more often than people with just normal allergies to pollen, ragweed, animal dander, etc. For many asthmatics a small level of dust or airborne particulate can trigger an asthma attack and the only relief comes in the form of an inhaler or other quick acting medication. 

Allergy sufferers can take a number of over the counter medications to help relieve symptoms especially the runny nose, irritated eyes and general stuffed head feeling that are very typical. Being in an environment where they amount of allergens can be reduced will significantly help reduce or eliminate the typical reactions associated with allergy sufferers. 

Pure Air Systems has been making HEPA based, fan powered air filtration systems since 1985. For over 39 years people around the U.S and overseas have been able to use these high performance air filtration systems from general duty air particulate removal to surgical suite operations and everything in between.  The ability to use these systems with standard forced air ducted heating/cooling systems has enabled thousands of allergy sufferers to have almost complete relief when they are in their homes or offices. The HEPA filters are commercial grade and certified at 99.99% at 0.3 microns and larger. The three stage filtration system also includes a dual layer ring panel filter and carbon media filter for odors and gases.

For asthmatics, the PAS line of HEPA systems has proved to be one of the few HEPA based air filtration systems that can both  reduce the levels of airborne particulate while also pressurizing an entire house, office area or large room. This highly effective system has shown to significantly reduce the need for or use of inhalers for the area being actively filtered. Pure Air Systems also makes portable units that can handle an individual room or small area. These are perfect for a child’s or adult’s bedroom or small house or condo.
