N95 Mask Fit Testing

We understand the difficult times that everyone is experiencing and want to be there to keep you safe.

Since N95’s come in all types of sizes and shapes, mask fit testing is essential to ensure you are wearing the best mask for you face and have a tight seal. While there is two different types of mask fit testing we choose to conduct QUANTITATIVE mask fit testing which ensures accuracy and safety for our clients.

Let us help you stay safe and prepared, schedule a fit testing with us today!

Quantitative mask fit testing is objective in comparison to qualitative. Quantitative fit testing measures the precise amount of air leaking from the mask. Instead of the participant relying on their sense of taste and smell, the mask will connect to a machine that measures the number of particles in the ambient air around them versus the number of particles that are inside of the mask. canaPHEM uses the portacount machine to conduct quantitative testing.



Qualitative mask fit testing is extremely subjective and relies solely on the participant’s sense of taste and smell for air leakage in your respirator. This mask fit testing is done by placing a hood overtop of your head while wearing an N95 mask. Either a bitter or sweet chemical is then sprayed into the hood and the participant must determine if they are able to taste or smell the chemical. If the participant tastes the chemical then the mask fails and the participant needs to find another mask to try and fit.


Under the Occupational Health & Safety Act it is required by law to protect the employee’s health and safety at all times and provide all of the proper equipment to allow the employee to work. This includes providing N95 mask fit testing for any and all individuals who are required to wear an N95 respirator to work. An employer is not able to issue an N95 mask to an employee without providing mask fit testing to ensure the N95 is a proper fit for that individual.
