Quantitative vs Qualitative

View our Qualitative Fit Testing Guide

There are multiple ways to break down the differences between Qualitative fit testing and Quantitative fit testing. Quantitative is data-based, provides a real objective metric, and usually tests the actual mask individuals will wear to protect them. Qualitative is based on a  series of sensory questions.

Types of Quantitative Fit Testing

AccuFIT 9000® Machines use the Ambient Aerosol Method (CNC) of fit testing, which can be performed in as little as 3 minutes, and works on full-face, half-face, and even disposable masks and respirators.

CNC Fit Testing

AKA Condensation Nuclei Counting.

  • Can test ALL types of respirators
  • Test fit in dynamic mode, while test subject is moving and breathing
  • Best correlation with gold standard
  • Much easier to learn and perform protocols
  • Produces direct fit factor

CNP Fit Testing

AKA Controlled Negative Pressure.

  • Cannot test filtering facepieces (N95 masks)
  • Test subject must hold breath and not move
  • Poor correlation with gold standard
  • Extremely operator technique dependant
  • Back calculated fit factor approximation
