Qualitative Fit Testing (QLFT)

Mask Fit Testing by Cavity Dental Staff

Qualitative fit testing (QLFT) is a pass/fail test based on the wearer’s subjective assessment of any leakage through the face seal region by detecting the introduction of bitter- or sweet-tasting aerosol as a test agent. QLFT methods are suitable for disposable and reusable half masks; they are not suitable for full-face masks. Although this type of test is based on subjective detection and response by the wearer of the RPE, it is important that it is administered by a fit tester competent in using this method.

Our experienced dental team, with a wealth of dental experience are now delighted to be able to offer a fit test service for FFP3 , FFP2 and FFP1 masks.

Using the 3M qualitative testing kit, we are able to arrange appointments at your practice to fit test your staff, with your own masks.

As we know, no two faces are the same and often we find, not one style “fits all” we have a variety of masks, we can also “fit test ” your team with, if you need alternatives. You will be able to buy a small supply on the day to get your team under way, being able to then source from your preferred consumables supplier thereafter.
