3M FT-31 Replacement Sensitivity Solution — Bitter for Respirator Fit Test Kit

The 3M FT-31 Replacement Sensitivity Solution is the official substitute designed for use with the FT-31 respirator fit test kit. This bitter-tasting medium is formulated to replace the initial sensitivity solution when your testing session requires a fresh batch, helping to keep your qualitative fit testing routine moving smoothly. By using a replacement item from the same trusted brand, teams can maintain consistency in their test setup without altering established procedures.

In real-world settings, test accuracy and kit reliability can hinge on having a ready-to-use sensitivity medium on hand. The FT-31 solution is designed to slot into the existing workflow with minimal setup, so testers can focus on the process rather than on sourcing replacements mid-session. The Bitter designation signals a clear, detectable reaction within qualitative tests, a common cue during routine fit checks.
