Do you need quantitative fit testing?

Highly accurate fit testing is available with Quantifit partial pressure measurements taken inside the mask vs pressures sampled outside the mask. Other fit testers measure the particles inside the mask, which makes testing places smokers being fit tested in an ackward position compared to non-smokers. Quantifit fit testing technology is smoker friendly.

A fit test adapter is attached to the threaded connector of the APR Adapter and a sample tube is inserted through the APR Adapter inhalation valve. A barbed fitting on the fit test adapter body may be connected to an appropriate quantitative fit test apparatus.

Do you need qualitative fit testing?

The qualitative fit test provides the user with a qualitative measure of the fit of the respirator. First, a sensitivity test is performed to determine if the test subject can detect the test agent being used.

Once it is determined that the test subject can sense the test agent, a qualitative fit can begin. The subject will perform a series of activities while wearing the respirator inside a testing chamber filled with test agent to ensure a proper fit.
