3M offers two qualitative fit test kits FT-10 (sweet) and FT-30 (bitter); FT-10 uses a test solution of sodium saccharin that produces a sweet tasting aerosol and FT-30 uses denatonium benzoate to produce a very bitter taste.
Simply spray the fit test solution into the hood environment. If the wearer does not detect the test agent's taste, an acceptable fit has been demonstrated. Can fit test approximately 150 employees
