There are two essential technologies for respirator fit-testing: Ambient Aerosol, which is particle-counting aerosol technology, and Controlled Negative Pressure (CNP) by OHD. We have conducted an ROI Analysis to highlight the strengths and weaknesses of each technology.

In the ROI Analysis, we found that:

  • CNP technology can test over 100 MORE masks a day than an ambient aerosol device.
  • The Quantifit has the lowest initial cost AND service cost.
  • CNP measures 97.9% of known calibrated leaks.
