Qualitative fit testing is a simple pass/fail test based on the wearer's subjective assessment of the leakage, via the face seal region, of a test agent, usually a sprayed solution of a sweet or bitter tasting substance. These tests are relatively simple to perform and are suitable for half masks and filtering face pieces. They are not suitable for full face masks.
