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.

Walking through an old grave yard the other day I noticed some unusual scripting on some of the tombstones. The typical “born date” “died date” were present on all of them but a few had more creative wording on the granite markers. One of the most popular epitaphs that has been written in dozens of languages world wide is…”I Told You I Was Sick.” I found this on two head stones. I’m sure the deceased relatives didn’t think it was funny, but somehow I think this comment says it all.

People complain about everything today. And with the help of social media they can do it 24/7  and have the world be their sounding board. For many people, complaining about their health or how certain issues affect their health has become their favorite hobby. However, in many instances these “cry wolf”  health concerns are actually valid complaints. Negative reactions to various foods, environmental conditions and industrial pollutants, both liquid and air, are more common than ever.

Pure Air Systems has been manufacturing commercial grade, certified HEPA and Carbon based fan powered air filtration devices since 1985. Our experience in working with individuals, environmental specialists, Allergists, Physicians and Industrial Hygienists has provided us with a wealth of  practical application knowledge regarding the overall effectiveness of our HEPA filtration systems.

Individuals who either are pre-disposed to a specific type of allergen or pathogen or those who have weakened immune systems due to  constant contact with airborne contaminants (both particulate and gaseous) and who have used one of the Pure Air Systems HEPA units in their living and/or work environment, have achieved excellent results with the systems. In almost every case where an individual was experiencing some physical or respiratory distress from their polluted environment, the introduction of the PAS HEPA systems provided a minimum of 70% relief with the majority of individuals having virtually no symptoms at all.

While these results are not derived from a scientific, long-term study, the fact that people have continued to purchase the PAS products for over 27 years has proven the market recognizes the ability for the systems to excel and provide the performance as promised by Pure Air Systems.

For years individuals have complained about certain health issues that they believe are directly related to their living or work environment. Often these health issues are discarded by the medical profession as emotional or psychosomatic. While there are some instances where this is true, for the most part the symptoms and the suffering is real. Recently the medical profession has determined that the underlying cause for many of the “environmental illness” issues are now related to fibromyalgia…which can be treated to a certain extent with medication.  However, contact with our customers who have been diagnosed with this disease have found that it is the “easy out” diagnosis for everything environmental.

The fact is that those people who suffer from constant contact with any type of allergen, gaseous pollutant or pathogens continue to find more relief when living and working in a cleaner environment. Especially when they use one of the PAS HEPA systems. For individuals who do have an issue with the air they breathe contacting us now is better than having to write something too soon like, “I told you I was sick,” as your epitaph.

Ever since the movie the “Right Stuff” came out, the use of the term Right Stuff has come to symbolize the best of the best for both men and women. And it has been used to identify a product or process that continues to be a leader in performance and reliability.

Pure Air Systems manufactures a line of HEPA and Carbon based air filtration systems and has been doing this since 1985.  From the initial design the goal was to build the best possible air filtration system using tested and proven commercial grade components and then offer the systems to the residential as well as the commercial market.

Over the past 25 years the PAS systems have become known as the best high performance HEPA based air filtration systems on the market. The addition of the ECM digitally controlled, 120/240v 50/60Hz motors to the systems allowed the units to be used not only in more commercial applications but also anywhere in the world.

The systems are designed so that they can be used in multiple configurations, applications and processes. The PAS units can be used either attached to an existing HVAC or air handler unit or as stand alone systems. And the ECM motors allow for finite speed control from 10% of volume to 100% of volume in 1% increments. This finite speed control allows the systems ( which range in maximum volume from 600 CFM to 200 CFM) to be adapted to almost any application requiring both true certified HEPA filtration or Carbon adsorption systems with exacting air flow control over pressure drop.

For Architectural & Engineering firms the PAS line offers a unique product that the engineers can adapt to applications requiring this type of filtration, power, performance and reliability. And, because the systems use motors that have a universal electrical rating, these systems can be installed anywhere in the world. This is a huge advantage for  A&E firms as they no longer have to ask the supplier to modify or change the product to meet an overseas or commercial electrical requirement.

The PAS units are all fabricated from high strength steel and powder coated painted. This allows for use in any environment and many of the PAS systems that were sold in the last twenty years are still in operation. A true testament to the design and fabrication of these systems.

So, for A&E firms looking for the “right stuff” all they have to do is go to our website at: www.pureairsystems.com and they will be able to obtain all the information they need to select the right system for their application.

Architectural and Engineering firms offer engineering and design services primarily for the commercial, industrial and institutional markets.  They may design, engineer and/or specify the types of equipment, controls and materials required to bring a project to completion.

For projects that require some form of HEPA based air filtration for sanitary processes, drug manufacturing, food processing, clean room applications and medical product and health care facilities, A&E firms often work with and incorporate Pure Air Systems HEPA based air filtration systems.

The HEPA based filtration systems offered by Pure Air Systems ( PAS), offer some of the more unique capabilities and features of any HEPA based air filtration system on the market today. First, PAS makes some of the largest and most powerful stand-alone units incorporating both a three-stage filtration system along with the Genteq (GE) ECM variable speed 120/240 volt 50/60 Hz motors.

The three main units, 600HS, 1200HS and 2000HS systems are capable of moving from 100 to 600; 100 to 1200 and 100 to 2000 cfm respectively. Because they incorporate the ECM variable speed motor they can be applied to a wide variety of applications requiring HEPA filtration where specific volumes of air are required and the electrical requirements demand 240 volt motors.

The PAS units are also relatively small and light compared to their overall capabilities. The 600HS is only 97 lbs and the 1200 and 2000HS units weigh just over 200lbs. These units are configured in two different housing styles. One version is configured like an L with the inlet at the top and the discharge at the bottom side. The L versions are comprised of two separate sections that are symmetrical so the top and bottom section can be rotated for any inlet-discharge design requirement.

The S versions, or straight through versions, have the inlet and discharge openings at the ends. These horizontal units can be mounted vertically as well as horizontally and the 1200HS and 20ooHS units each have weld nuts located on the top four corners for ease of mounting.

From an Engineers point of view, the PAS units provide a unique blend of  performance, power, control and durability not found in any other HEPA filtration system today. The fact that the PAS units come standard with a scanned 99.99% at 0.3 micron HEPA filter, carbon media filter and ring panel prefilter means that these units can be applied to almost any application where true, certified HEPA filtration is required.

PAS has been making commercial grade HEPA filtration systems since 1985 and has more HEPA systems installed in commercial applications in North America, Europe and Asia than any other HEPA filtration company.
