Experience the latest innovation in respirator fit testing with AeroFit, a cutting-edge quantitative CNC fit testing device engineered for precision and ease with the new AeroFit CNC Fit Tester.

What makes a CNC fit tester above the rest?

The CNC testing system measures the concentration of ultrafine particulates in the ambient atmosphere, then measures the concentration of these ultrafine respirable particulates in the breathing zone of the respirator. This takes place while the test subject is actually moving and breathing.

The ration of in-mask particulate to ambient particulate is the "Fit Factor" which directly measures how well the respirator fits.
