In 1985, Don Musilli founded a company to sell high end HEPA air filtration systems to the residential market. HEPA filtration at that time was somewhat limited to the micro-chip manufacturing industry, asbestos abatement companies, medical operations and some industrial applications. The residential market was using standard pleated, card board box framed general duty filtration media filters or electronic air cleaners. These air filters were located either in the main return air grills or at the point where all the return air entered the main air handler ( HVAC unit ) and were designed primarily to remove very large airborne particles and to keep the cooling coils and fan blades clean.They did little to remove the smaller, respirable sized particulate that could create health issues for many homeowners.

Whether we are indoors or outside, we are breathing air that contains various sizes of particulate. The larger particles. those that you can see with the naked eye, are usually 20 microns in size of larger. ( for comparison, your hair is 100 microns in diameter ). These larger particles are aspirated into our lungs and the majority of them are exhaled out. The smaller, sub-micron particles however, ( those less than 20 microns in size ) tend to stay logged in the lung linings and mucus membranes. These smaller particles may represent a wide range of organic and inorganic materials including pollen, pet dander, ragweed, bacteria, viruses and industrial pollution. For those individuals that suffer from allergies many of these airborne particulate are the primary cause of their respiratory dysfunctions.

Pure Air Systems pioneered the use of HEPA filtration systems with their first model 600H unit.that included a true, scanned HEPA filter rated at 99.99% removal of all particles 0.3 microns and larger, a wire framed ring panel prefilter ( to keep the HEPA clean ) and a true carbon filter to remove odors and gases. These systems were designed to attach to the return air side of a ducted HVAC system using the partial by-pass concept. This unique concept allowed homeowners, for the first time, to use a true HEPA filter system on a residential HVAC unit. These HEPA systems cleane all the air in the house up to 24 times a day and remove a very large percentage of the sub-micron, airborne particulate. 

Thirty Four years later, PAS has added 6 more HEPA, fan powered, air filtration systems to its stable and over 10,000 of these units have been installed in homes and offices across the U.S. and Canada.

About the Author: Don Musilli

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.
