Bitter Qualitative Respiratory Fit Test Kit

This qualitative fit testing solution helps determine whether a respirator forms a proper seal on a user's face. The test uses a bitter-tasting aerosol solution called Bitrex™, which is introduced around the respirator while the user performs a series of movements and breathing exercises. If the user can detect the bitter taste, it may indicate that the respirator is leaking and does not fit correctly. By helping verify respirator fit, the process supports workplace respiratory protection programs and assists safety professionals in meeting applicable safety and compliance requirements.
