The Bitrex Fit Test Kit tests all disposable and reusable dust and mist respirators for OSHA compliance. Shown to be safer and equally as accurate as saccharin tests.

Apparatus can be used with any NIOSH particulate or gas/vapor respirator with a particulate prefilter to test face-to-respirator seal.
