Qualitative and Quantitative Fit Testing

What is face fit testing?

Face fit testing is a method used to ensure a tight-fitting face mask (RPE respiratory protection equipment) is sealing against the wearers face to significantly reduce their exposure to any airborne hazard. As we do not all have the same shape / size face, we cannot assume a mask is providing adequate protection unless it has undergone a face fit test. As an employer, if any employee needs to wear a tight-fitting mask, this is a legal requirement, and as an employee it provides reassurance they are protected.

Why choose Cavity fit testing? 

We have experience in face fit testing, and we have Fit2Fit accredited fit testers in our team. Meaning our methods have been checked and confirmed with best practice for face fit testing in line with the BSIF and HSE. Good knowledge and technique are essential when conducting a fit test, poor execution could result in employees being exposed to dangerous hazards causing serious health conditions.

We have fit testers based right across the UK and can come to your premises to fit test you and your employees, or you can come to our premises.

Fit Testing with Cavity


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.

What our customers say

I really enjoyed yesterday training. I have learnt so much! Sarah and Lisa were amazing with the training, it was not boring at all! And thank you so much for the training kits.

The fit test training was great and it also helped me feel more confident donning my FFP3 mask correctly.

Sara & Jasmine recently attended my practice to complete fit testing on me and my team and I found the whole experience very professional and very informative. I was watching both Sara and Jasmine and learnt so much from them. They are both lovely and very professional ladies and I felt comfortable with the fit test. Thank you.
