Pure Air Systems has been making commercial grade, fan powered HEPA based air filtration systems since 1985 and has seven different model and size configurations to fit any commercial, medical, industrial or residential application for reduction and/or removal of sub-micron airborne particulate. Recently, GOTO RX, a company based in Ontario, Canada that specializes in pharmacy clean rooms and other products for the pharmacy industry, recently purchased a 2000HS HEPA filtration system from Pure Air Systems to tests it’s effectiveness using a smoke test by the College of Pharmacists, Air Quality test protocol. The unit was mounted in the ceiling of two clean rooms with short duct runs to a number of inlet points to capture the smoke that was generated by the testing equipment.
William Fretwell, President of GOTO RX provided this description of the smoke test and the results. The 2000HS was tested at a flow rate of 43% of maximum ( 2000HS can move up to 2,000 CFM ) with a room air change rate of 45 air changes per hour which is above the 30 changes per hour normally required for this type of clean room. So there was lots of spare capacity. During the smoke test where a special chemical is used to generate smoke that is extremely fine with much of it invisible to the naked eye, the particle counter found no smoke passing through the Pure Air Systems HEPA unit. The 2000HS created a clean room environment in both rooms with a Clean Room rating of Class 6, which is 10 times cleaner than the required standards. William Fretwell commented that, ” most hospitals don’t have anything up to this standard”.
As a result of the successful test results, GOTO RX is planning on publishing an article for Pharmacy Practice Magazine with the title, “The New Clean”. It is important to note that PAS has been using their HEPA based filtration systems for over 35 years in a wide variety of clean room type applications with superior results.
