How N95 Masks Really Work

There is a lot of misinformation about the way N95 respirators work and in fact what the designation actually means. In order to understand the  AAC/CPC method of fit testing, it is really helpful to first understand the filtration mechanisms that occur in the Filtering Facepiece Respirators such as the N95 series. We recently found […]

How Long the COVID Virus Can Live on Surfaces

One of the many important things to know about the particular strain of coronavirus which is the etiological agent of the current pandemic is the length of time the virus can remain infectious when it is in the environment. This exceptionally well written and documented letter was published in the New England journal of Medicine […]

The Difference Between CNC & CNP Fit Testing

Two Quantitative Fit Testing Methods Respirator fit testing is becoming more important all the time. There are currently two commonly-used methods for performing quantitative fit testing:  Condensation Nuclei Counting (CNC) and Controlled Negative Pressure (CNP). So, what’s the difference?  CNC Fit Testing By far, the most widely used method is the ambient aerosol method using […]

How to Setup the AccuFIT9000 Fit Testing Machine

Hi, I’m Wesley with Accutec-IHS. The AccuFIT9000 is a new instrument for performing respirator fit testing which depends on measuring the fit of a tight fitting respirator by comparing the ratio of the respirable particles in the breathing zone, with the concentration of these ultra-fine particles in the ambient atmosphere. This technology is called condensation […]

How to Protect Against COVID Spread With Respirator Fit Testing

Both CDC (Centers for Disease Control) and WHO (World Health Organization) have now recognized the 2019-nCoV coronavirus outbreak as being serious. One of the more concerning developments is the fact that 2019-nCoV has shown to be capable of human-to-human transmission. This was first documented in this country today, January 30, 2020, in Chicago where a […]

Respirator Fit Testing Methods: Controlled Negative Pressure (CNP) vs. Ambient Aerosol

In summary, it can be demonstrated that the Ambient Aerosol method as used in the AccuFIT9000 is traceable to and compares extremely favorably to the proven “Gold Standard”.

The Optimal Environment for Respirator Fit Testing

CPC-AAC fit testing measures the concentration of these particulates in the breathing zone while the test subject is performing a series of exercises designed to stress or breach the seal of the respirator as they are wearing it.

What OSHA Says About Respirator Fit Testing

The AccuFIT9000 has been designed to meet the requirements of the Condensation Nuclei Counting Fit Test protocol as described in 29 CFR 1910.134

Cost Savings with AccuFIT 9000

Because the official protocol required to perform a legally-valid qualitative (i.e., Saccharine or irritant-smoke) fit test is time-consuming and labor-intensive many practitioners omit required steps in order to simply get through the process.
