Blog Tag: Virus

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. These all metal units utilize the latest in variable speed motor and digital controllers to meet any application.

You can either put you head in the proverbial sand like the Ostrich and believe this is not a problem or grasp the real issue of this virus being around forever and changing and adapting to the new vaccines that are currently on the market. Too many people use other methods of gathering data, especially social media, on health care issues rather than from their medical professionals. This never ceases to amaze me.

Viruses are extremely small and very light and can travel up to 20 feet or more when expelled from a human mouth. While we realize many of the face masks are not capable of removing all of the viruses, they are a great barrier non the less. 

The use of air filters in your home or office are minimally capable of removing very little of the airborne viruses. The only air filters that can do that are HEPA filters and those are normally used in hospitals, surgery rooms and chip manufacturing. However, there is a company that has been around for over 37 years that makes a HEPA air filtration system that can be attached to any HVAC ducted residential system and even used as a stand-alone unit. 

Pure Air Systems has been making commercial grade HEPA and Carbon based air filtration units since 1985. These units range in air flow capacity from 50 CFM up to 2,000 CFM and come in seven different configurations. Over the past 37 years these units have been used in a wide range of air  filtration applications around the world. Pure Air Systems is now one of only 3 companies in the world that make this type of fan powered, HEPA based air filtration system.

When Pure Air Systems was established in 1985, there were a number of companies selling HEPA like and HEPA type air filtration systems. Many of these were used in the Asbestos Abatement projects that were prevalent at that time. In fact, Pure Air Systems was a spin-off from HEPA unit designed for abatement but never got into production.

The model 600H unit was a unit with a prefilter, carbon media filter and true commercial grade HEPA filter with a 1/3HP GE motor and Lau Blower. It was in one large section which was subsequently broken into two sections. This was the beginning of the PAS Line of HEPA systems. 

As the popularity of the 600H unit grew, PAS introduced the new ECM motors from GE to make the HEPA system available as a stand alone unit as well as using variable speed motors that were then being introduced by all the HVAC companies.

By 1999 PAS had grown the line from one unit to seven different systems including the new portable unit. It has also moved into a new 9,000 square foot building. As of this date, 90% of the units are still built with parts made in the USA and it is now one of only 3 companies in the world that make this type of HEPA with the size and flexibility in size range and air flow control.

HEPA filters are the best method of removing sub-micron airborne contaminants including, viruses, bacteria, dust particles and airborne allergens ( mold, pollen, etc.).

One of the challenges of using HEPA filters in a residential application is how the HEPA filter is installed to best gather the greatest amount of airborne particles from all rooms of the home. Most air filters in residential HVAC systems are either placed in the air returns for each room or one largepr filter is placed at the return air inlet of the main HVAC fan unit. 

Since HEPA filters have a much higher resistance to air flow than standard duty air filters, they need to be placed in a cabinet that includes its own blower/motor section to assist the air flow through the HVAC system so there is no disruption to the air flow from the HVAC unit. 

Pure Air Systems developed a HEPA filtration system that incorporated its own blower/motor unit along with a true commercial grade HEPA filter, prefilter and carbon media filter. This metal framed housing unit could be attached to the return air side of the HVAC system in what is called a “partial pass” concept. In essence, the HEPA system would pull anywhere from 600 CFM up to 2000 CFM of the return air ( the later used mostly in commercial systems) and then return it back into the HVAC system on the supply side. In this manner the HEPA system would clean all the air in the house after the 3rd or 4th pass. Or, approximately 30 to 50 times  day, depending on how often the HVAC fan system runs.

The PAS units all utililze the newer variable speed drive, digitially controlled motors that can be programmed to operate in sync with any HVAC system.

Pure Air Systems began its journey in 1985 producing one of the first true, commercial grade, fan powered air filtration system that could be used in either commercial or residential applications. These units were made from 20 gauge mild steel that is powder coated for a durable, long-lasting finish. 

Today, the line up of 7 different systems made in variations in both size and air flow design are still made from the same high-grade 20 gauge powder coated steel housings now using the latest iteration of the variable speed drive motors that are digitally controlled. The HEPA filters are all 99.99% efficient at .3 microns and larger and the prefilters and carbon filters come standard with each unit. 

The HEPA Shield systems come in air flow ranges from a low of 50 CFM from our portable unit up to 2,000 CFM on our largest model 2000HS unit. These systems can also be modified to be attached to an existing HVAC duct work system or as stand-alone units. 

Pure Air Systems are all made here in the USA with most of the components manufactured in the US. Some of the original units are still in operation and the average longevity of any of the systems is better than 15 years. Making the PAS units one of the best economical purchases for any air filtration system on the market today.

Started in 1985, Pure Air Systems has been making commercial grade, fan-powered, true HEPA air filtration systems for over 38 years. The same high quality metal fabricated housings used then are still used today. High quality ECM motors and metal framed HEPA filters along with carbon media and ring panel prefilters are all part of the various systems offered by Pure Air Systems.

PAS makes units a number of systems ranging in air flow from 50 CFM up to 2000 CFM. These units are configured so they can be mounted either as stand-alone units or as part of an existing, ducted HVAC system. The powder coated painted 16 gauge steel housings can be mounted in side or outdoors depending upon the application.

The ECM motors provide for variable speed control using digital controllers or run by a computer system. In addition, they can be used in a a120 volt 60Hz electrical system or 240 volt 50 Hz system. This means they can be use in any location around the world.

HEPA filters are the best method of removing over 99.9995% of all particles 0.3 microns in size and larger and approach 99.99% for particles as small as 0.12 microns. They are used in all hospital and medical facilities and in commercial, military and residential markets.

3D Printing or Additive Manufacturing as it is called in the commercial market, has moved into almost every facet of manufacturing from small replacement parts and dental fittings up to Aerospace and Military applications. There are very large 3D printers making boats as well as printing houses and large structures and small bridges.

3D printing has a number of advantages including the ability to try the “what if” and prototyping of new design concepts. In addition, the materials available for the metal printers has moved this process in the main stream of manufacturing. 3D Printers take up much less space than traditional CNC machines and other fabrication systems and require fewer people to complete the manufacturing process.

One of the main advantages of using 3D manufacturing is the ability to get younger people to become more involved with manufacturing. The younger generation is very familiar with and is good at using CAD type software for design and 3D printing of parts. In truth, the ability to make things using 3D printing or Additive Manufacturing is not considered manufacturing to the younger generation. This is important as they are not interested in moving into the old type of making things. 

Pure Air Systems, an air filtration company started in 1985, has bee using some 3D printing processes for prototyping new parts for their metal housed HEPA based air filtration systems. This helps them more quickly determine the correct part design and more quickly complete the final design and get into production with minimal cost.

The Covid issue has been dissected by everyone in every discipline including social media. The fact remains that Covid is virus and like all other viruses it is extremely small ( less than .012 microns in size ) and easily transmitted through the air. While the various types of face masks that are available are not truly capable of removing 100% of the airborne viruses, they can significantly minimize the levels of virus ingestion. 

In 1985 Pure Air Systems introduced an air filtration system utilizing true, commercial grade HEPA filters for the residential and commercial markets. These fan powered systems are capable of either being attached to existing HVAC systems or stand-alone. 

HEPA filters are used in all hospital surgery suites, laboratories, pharmaceutical companies, chip manufacturing and more. These filters are specially designed to remove airborne particles as small as viruses and are extremely efficient over their life. The type of filter media used in the HEPA filters is partially copied in some of the new face masks now on the market. Then N95 mask is one of them.

It is important to know that the viruses that are now out in the world are extremely capable of changing and adapting to new drugs and pharmaceuticals, therefore making them around as long as we inhabit this planet.

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.

Covid-19 has reignited the air filtration market with new ( old technology ) being offered to the public as the panacea for removing viruses from the air. Unfortunately, these old technologies are being regurgitated as the panacea for keeping you safe from airborne viruses such as Covid-19, et al.  UV lights are good for illuminating finger prints on glass if you are a forensic scientist searching for a perpetrator but this light does very little to destroy airborne bacteria and viruses. For UV light to have any affect on airborne contaminants, the particles need to be exposed for a long period of time ( from 1 to 10 minutes). Since most UV lights are installed in HVAC systems the speed of the air passing by the UV light somewhat defeats the purpose of using the light in the first place.

Ozone Generators have been around for more than 40 years and were used originally to reduce odors in commercial applications. Ozone is made up of 3 Oxygen molecules and will easily give up one of its molecules when it comes in contact with another gaseous molecule and changes the chemical nature of that molecule. This is how it reduces odors by simply changing the chemical nature of the odor producing molecule. Ozone also attacks carbon based objects and humans are basically carbon based forms. For airborne particulate, Ozone is not effective as it does not have any capture mechanisms to reduce the level of the particulate. Again, particulte would have to be in contact with the Ozone for long periods of time to have any affect at all.

Mechanical air filters, which include all media air filters including HEPA filters, are the only mechanism available to remove and capture airborne bacteria and viruses. This is why all Hospitals, clinics, laboratories and other medical facilities use HEPA or HEPA type filters to protect the occupants from viruses such as Covid-19. Even the lesser efficient air filters that are used in homes and offices that  have some minimal effect on removing viruses are better that using UV lights and Ozone generators.
