Moldex-Metric Respiratory Protection & Fit Testing

Moldex-Metric builds respiratory protection around a simple truth: a respirator only works if it fits and workers actually wear it. That's why this collection pairs the masks themselves with the qualitative fit test kits that verify a proper seal — the two halves of a compliant respiratory program under OSHA 1910.134.

For fit testing, the Bitrex line is the standard for taste-based (qualitative) protocols. You run a sensitivity check first with the Bitrex Sensitivity Solution (0503) to confirm the wearer can taste the bitter agent, then challenge the sealed respirator with the Bitrex Fit Test Solution (0504) inside a test hood. The complete Bitrex Qualitative Fit Test Kit (0102) bundles the hood, nebulizers, and both solutions so a safety officer can fit-test a crew without sourcing pieces separately — and replacement solutions and spare hoods (0201) keep the program running between annual re-tests.
