Pure Air Systems Is Major Supplier Of Filtration Systems To Fight Covid-19

Created in 1985, Pure Air Systems was one of the first US companies to offer commercial grade, fan powered, HEPA air filtration systems for the general publc. These systems are designed to be used as both stand-alone units as well as attaching them to existing HVAC systems to provide central and whole house filtration. Over the next 10 years Pure Air Systems developed seven different sizes and configurations varying in air volume capacity from 50 CFM to 2,000 CFM. In addition the systems had the capacity to add carbon media and prefiltration in conjunction with the HEPA filters providing systems that could handle almost any air filtration or odor challenge in the market.

When Covid-19 entered the globe in eary 2020, many of the hospitals, clinics, laboratories and municipal facilities across Norht America started lookng for HEPA based air filtration systems as HEPA filters are the only type of air filter that can remove a subtantial amounty of airborne viruses. Standard air filters are, for the most part, not very effective in removing these sub-micron particulate from the air. 

The Pure Air Systems units use very powerful, variable speed drive motors ranging from 1/3 HP to 1 HP, they can move a lot of air through the HEPA filters which are extremely dense. In additon, the units can move air through ductwork that is connected to the filtration systems so they can be used to provide clean air in a large space. The systems can also be used to create either a positive or negative room area for patient isolation as is the common practice in most Hospitals.

Today, Pure Air Systems is one of only three companies around the world that produces a metal framed, commercial grade, fan powered true HEPA air filtration that can be used in a very wide range of applications in the residential, commercial, institutional, industrial and medical markets.

Do UV Lights Really Kill Covid 19 ?

Ultra Violet lights (germicidal lamps) or UV systems come in both a hot (8,000 hours life) and cold plasma (rate 36,000 hours life) lamp systems. They produce a specific wavelength of 253 nanometers and produce UV C. This wavelength has the ability to affect microbiological contaminants like mold and bacteria. The UV C light can destroy the DNA of the microbiological and keep it from replicating. UV C has no effect on solid particles and it does NOT remove anything from the air stream. UV C lights are normally placed in the return air stream, although the speed of the air past the lights can minimize the effectiveness of the UV lights. We suggest that placing a UV light at or near the cooling coils works better as the light can irradiate this moist area all the time and help in minimizing the growth of mold or bacteria. UV lights are an ancillary piece of equipment and should always be used in conjunction with an air filter or air filtration system.

The Use of UV lights to reduce or kill Covid 19 viruses is somewhat limited to the distance to and the duration of time it sees the virus. That is why UV lights are more effective placed in the return air duct of the HVAC system and the fan has to be running all the time. Further more, you need really good filtration in front of the UV lights otherwise they will become coated with dirt and dust and thus significantly reduce their effectiveness.

If you look at the miriad of photos and TV footage of Hospital wards treating Covid 19 patients, you never see any UV lights in and around the patient beds. Sterilaztion with chemicals and the use of PPE are much more effective in that area of the hospital. The real danger in using UV lights is the thought that this technology is a primary method of eliminating the Covid virus when in truth it is  only a terciary device at best.

Pure Air Systems has been making HEPA based air filtration systems for over 35 years and today the use of HEPA filters has become the primary method of maintaining surgery room cleanliness in Hosptials, Clinics and laboratories all working with Covid. 19.

Science Is Our DNA

SInce man first walked on the earth he has been finding ways to make life easier, safer and more productive. His inate drive to explore and learn are bult into his DNA. It is a survival of the fitest condition. Everything we use and have at our disposal was invented by man ( or woman ). The balance is deliverd by Mother Nature, which is, in many ways, more powerful and more important. . Some of those things Mother Nature delivers include diseases that are benign to animals but cause significant challenges to man. In some cases man’s own drive creates the conditions by which these diseases become deadly. 

Covid-19 is science. It is biological science and it plays with our DNA. As a virus it follows the same drive as man..survival of the fitest. It will do whatever it takes to keep growing and moving as it jumps from human host to human host.It really doesn’t have a conscience or any political aspirations and is not threatened by any medicine was currently have at our disposal. It will command our attention for a very long time. It is a variant of science so obviously it will require science to tame it. Man has the ability to resolve this issue if it is taken seriously. If not, then perhaps we should paraphrase the words in Matthew 5 where he says ‘ and the meek shall inherit the earth.”

Pure Air Systems has been making HEPA based air filtration systems since 1985 and is now working around the clock to supply a wide variety of medical and commercial operations with HEPA filtration systems to help deal with the Covid-19 pandemic.

Un Masking Covid -19 Size Does Matter

Wearing a mask during the current pandemic has been accepted by and also rejected by large portions of the US population.Some of reasons are political, some are irrational and some are based on science. The latter being the more logical rationale.

It seems that the, “What you don’t see won’t hurt you”, mindset has taken over our ability to feel threatened by the virus. Yet, this virus like all airborne viruses has no concience or cares little about your ability to see it. You can only see particle sizes down to about 20 microns with the naked eye and this virus is about 0.005 microns in size which makes it only visible using an electron microscope. When someone who has Covid-19 talks, coughs, sings or laughs they are expelling millions of sub-micron particles into the air, some as droplets some as fine, invisible mist. The closer you are to that individual and the longer you stay in close proximity to that individual the larger the concentration of the virus you will breathe in. Unless of course you are wearing a mask.

The use of any covering over your mouth and nose is by far much safer than wearing nothing at all. Maks will prevent you from getting high concentrations and also minimize the amount of the virus you may transmit if you are infected. It is, in essence, the human thing to do.Covid -19 will continue to be with us for a long time just like the other Covid viruses for which many of us get inoculated each Fall to reduce our chances of getting the Flu. And, like the Flu this virus is always changing and the longer it stays around the more virulent it becomes and the less exposure you will need to become ill.

Covid-19 A Different Type of Media

THE MEDIA is getting a lot of attention these days and depending upon which side of the aisle you sit your position about this pandemic is dependent upon which media outlet you watch or listen to. The term “media” also refers to the type of filter materials used in air and liquid filtration. In the case of these types of materials, they are not subject to opinions or bias. Filter medias have a specific protocol they must pass in order to have a rating for a certain efficiency of particulate removal of certain sized particles.

Pure AIr Systems, founded in 1985, has been making fan powered HEPA based air filtration systems for the commerical, medical, industrial and institutional markets with a very high degree of success. The HEPA media used in their systems is tested under very stringent test protocol to meet or exceed 99.99% removal of particulate 0.3 microns in lager and approach 95% on particulate smaller than 0.3 microns. 

The efficiency of this type of media doesn’t care where the particles came from or how they were generated or even the color and texture. It is a filtration media that is used globally and recognized as the best available filtration for removal of airborne bacterial and viruses. It is important to listen to the science not the hype.

Covid-19 HEPA Masks

The Corona Virus pandemic has brought out a cry for protective gear, masks, respirators and ventilators not to mention HEPA based air filtration systems to maintain positive pressure rooms in make-shift hospitals. HEPA filters are made from special paper-like materials that are extremely dense and designed to capture a very high percentage ( usually 99.99% or greater ) of sub-micron particulate. These filters are used in surgery suites, laboratories, chip manufacturing, and any place where airborne particles ( bacteria and viruses ) are present. 

With the Covid-19 pandemic there is a race to provide any type of mask for the first responders, medical personnel and now the general public. This demand has brought out a number of individuals and groups making masks ( or printing them ) out of various materials; mostly cloth of some kind. However, some are offering HEPA masks that look like a regular cloth type mask. True HEPA masks worn by first responders are PAPR masks. Positive Air Pressure Respirators.These masks have true HEPA filters in their design and also have fans to assist in pulling the air through the HEPA filters. These masks are battery powered. Without the assistance of the fan you would would have difficulty pulling air through the mask with your own lungs as the HEPA paper has extreme resistance compared to standard surgical masks. 

The N-95 masks are similar to MERV 8 air filters. They are good for 95% of particles in the 3.0 to 10.0 micron range. Certainly much better than cloth but not as good as HEPA media. The reason this is important is that viruses, such as the Covid-19 virus, can be as small as .0005 microns in size. As a comparison, your hair is about 100 microns in diameter. This sub-micron size makes Covid-19 airborne and allows it to pass through standard mask materials. This is why this virus is so deadly.
