Years ago there was a cartoons showing an ancient battle ground with half clothed warriors laying on the ground with long pointed objects sticking out of their backs. Two of the warriors left standing discussed the situation and one commented on the long sharp objects asking what do think they are? The other warrior pointed to the long deadly objects and said, ” some call it a spear some call it an arrow”.  in the end it didn’t really matter what they were, the warriors were still dead.

Objects and items often are called by a variety of names, but in the end if they do the same thing then it doesn’t matter what you call it.. or does it? If we use a wrench as a hammer to pound a nail because we can’t locate our hammer, did we not use the wrench to hammer the nail? And if so does this make this a hammer as well as a wrench? And, do you care?

Pure Air Systems has been manufacturing high end, commercial grade, fan powered HEPA based air filtration systems since 1985.  Air filtration devices have gone through a number of design and performance iterations over the past 30 years, but in the end they still remove airborne contaminants and particulate only with better performance and greater efficiency. Years ago the word  air purifier crept into the air filtration industry and soon became a commonly used term when referring to any device that cleaned the air. Ion air cleaners, ozone generators and any device that had some mechanism to assist in making the air we breathe a little cleaner grabbed that moniker.

Over time the PAS line of HEPA and Carbon based systems were often referred to as air purifiers even though the term is not mechanically correct. True certified HEPA systems are very different from the more general duty “air purifiers” on the market. The removal of airborne contaminants, bacteria and some viruses requires the mechanical action of the media used in the manufacture of HEPA filters. These sub-micron particles will not be significantly reduced by using Ion generators or ozone generators or the old style electronic air cleaners. Hospitals, surgery suites, the CDC, military, chip manufacturers, optics manufacturers all use true HEPA filters as their ONLY filtration systems for sub-micron particulate removal.

So while it is true that different objects can perform similar or the same functions, when it comes to the term HEPA air filtration, air purifiers are NOT even close to doing the same function. It is an important distinction.

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.
