As humans we take a lot of things for granite. Rotation of the earth which produces gravity, land to walk on and water to swim in, and the ever present source of life, the Sun.  Being able to breathe the atmosphere in our environment is also something we take for granite. Interestingly most of us know little about the air we breathe. For example, the atmosphere we exist in is comprised primarily of oxygen and nitrogen. Oxygen comprises 21% while Nitrogen comprises 79%..( actually a little less than 79% as there are some trace elements in the atmosphere as well). In reality we are actually Nitrogen breathers although at the surface pressure of 1 atmosphere our bodies don’t absorb the Nitrogen, but they do take in the Oxygen.

When you have a cold or some form of upper respiratory infection you often find it is difficult to breathe. In actuality the lungs are probably full of mucus and the surface capacity of the lungs to take in Oxygen are significantly reduced, therefore requiring longer and deeper breaths just to get the amount of Oxygen your body requires. This same problem exists when you have lung damage due to smoking or breathing large quantities of airborne particulate in your work place over long periods of time. Ingestion of small, sub-micron sized particles create challenges for the lungs as these particulate tend to stay logged in the lung linings and mucus membranes.  People who smoke have difficulty in running or walking long distances as they get “short of breath” very quickly.

Small concentrations of harmful, respirable sub-micron sized particles, inhaled over a long periods of time can also significantly impair the lungs ability to take in Oxygen. Individuals who work in environments where dust is generated on a continuous basis are more susceptible to lung damage than those working in an office type environment. Even when technicians where masks or respirators, these individuals are more at risk than most.

In 1985, Pure Air Systems was founded to provide a series of commercial grade HEPA and Carbon based systems for the residential, commercial, institutional, industrial and medical markets. Today, the PAS line of HEPA, fan powered systems are used in a wide variety of high performance applications around the world. Removal and reduction of small particles are the key benefit of using HEPA filters. Those used by PAS are initially rated at 99.99% removal of particles 0.3 microns or smaller and approach 98% removal of particles 0.12 microns and larger.

Over the years many home owners have purchased the HEPA units from PAS and found the number of colds, upper respiratory infections, allergies and even headaches were significantly reduced. The same is true of those companies and medical operations that used the PAS HEPA systems. Product through-put, reduction in transfer of airborne pathogens and allergens, increase in product quality and reduction in loss work time for employees were all positively affected when using the HEPA systems on a regular basis.

My name is Don Musilli. I started Pure Air Systems in 1985 and then sold it in 2006. I continue to consult for PAS and write their blog and control their Twitter account. I also, on occasion, make changes to the website. The company is now almost 26 years old and has been a major player in offering commercial grade, high performance HEPA and Carbon based filtration systems for the commercial, institutional, industrial and residential markets.

I currently reside in Englewood, Florida where I write blogs and do social media marketing for a number of clients.
