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.
