When Severe Acute Respiratory Syndrome (SARS) outbreak occurred in Toronto in 2003 a large number of hospitals throughout North America and Europe purchased and trained employees on using class N95 respirators in preparation of a potential outbreak in their area These respirators require fit testing to ensure that they are the proper size and have a "tight face to mask" seal. Current quantitative fit testing for N95 respirators use a condensation particle counter (CPC), in combination with an additional instrument, that alters the size range of the ambient particles used for the fit test measurements. Therefore the only particles used are particles that can be trapped by class 95 filters This fit testing process slows the normal respirator fit test time when using the CPC test instrument alone. The objective of this invention is to provide a process that allows N95 respirators to be quantitatively fit tested without the use of an additional instrument that alters the size range of the ambient particles. We are not aware of any other inventions that aim to reduce the fit testing time of quantitative fit testing N95 respirators using CPC technology. This invention aims to quantitatively fit test N95 respirators as quickly as N100 respirators.
