Coming into our 31st year of operation, Pure Air Systems HEPA based air filtration systems are the best and one of the only choices for high performance, fan powered, commercial grade HEPA filtration systems.

Today in the U.S., PAS is perhaps the only company that continues to manufacture HEPA systems that are powerful enough to move up to 2000 CFM of air through a commercial grade, 99.99% scanned HEPA filter and maintain that air flow even as the HEPA filter becomes more restrictive as it loads up.

Of course there are small, plastic housed, quasi-HEPA units on the market that move up to 150 CFM ( rated but not tested ) and they sell for less than $300.00. They are, however, not really capable of moving enough air even in a small room to adequately remove the level of airborne contaminants that may be creating some respiratory or other health issues for the occupants.

Because of the high grade fabrication using all metal housings, blowers and the newer ECM variable speed motors. the 7 different units have a long history of long life. Beginning in 1985, some of the units produced in the late 80’s and early 90’s are still in operation today. All they need are replacement filters which are easily obtained from PAS.

The seven different systems offer air volume capacities from as low as 50 CFM to 2000 CFM with incremental volume controls for all the units. All of the systems also come with Carbon media and when required, the HEPA unit can be removed and replaced with Carbon making the system an gas or odor removal unit for other applications.

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.
