What to Expect During a Mask Fitting

If your healthcare provider has recommended a mask fitting—whether for respiratory protection, workplace safety, or medical use—you might be wondering what to expect. Mask fittings are important to ensure your mask provides the best protection and comfort possible. Here’s a step-by-step look at what typically happens during the process.

1. Initial Consultation

The appointment usually begins with a brief conversation about why you need the mask. For example, healthcare workers, tradespeople, or those using CPAP therapy all have different requirements. The specialist will review your needs and explain the fitting process so you know what to expect.

2. Mask Selection

There are many different types and sizes of masks, from N95 respirators to reusable half- or full-face masks. The fitter will select a few options to test based on your face shape, job requirements, and comfort preferences. The goal is to find a mask that seals securely but still feels comfortable enough for daily wear.

3. Donning the Mask Properly

Before testing begins, you’ll learn how to put the mask on correctly. Proper positioning and strap adjustment are key to creating a secure seal. This step also ensures you can replicate the fit yourself later, without assistance.

4. Fit Testing

There are two common methods for fit testing:

• Qualitative fit test: You’ll wear the mask while exposed to a harmless test agent, such as a bitter or sweet aerosol. If you can taste or smell it, the mask isn’t sealing properly.

• Quantitative fit test: This uses specialized equipment to measure leakage around the mask and provides a numerical score of how well it fits.

The fitter may ask you to move your head, talk, or bend over during the test to see how the mask holds up in real-life conditions.

5. Education and Care Tips

Once the right mask is found, the fitter will explain how to clean, store, and maintain it. They’ll also review when it should be replaced and how to spot signs of wear.

6. Final Confirmation

You’ll leave the appointment with confidence, knowing your mask has been tested to protect you properly. You should also feel comfortable putting it on and adjusting it yourself.

A mask fitting doesn’t take long—typically 10 to 15 minutes—but it makes a huge difference in safety and peace of mind. By the end, you’ll know you have the right mask for your needs, worn the right way, every time.
