How do you properly fit and adjust a purge mask

A purge mask is an essential accessory for scuba diving. It provides clear vision, protection from debris and marine life, and a comfortable fit. However, it is important to ensure that your purge mask fits properly and is adjusted correctly to gain the maximum benefits. In this article, we will explore how to properly fit and adjust a purge mask.

Choose the Right Size

The first step in fitting a purge mask is to choose the right size. A mask that is too small will be uncomfortable and may not provide a good seal, while a mask that is too large may leak or slip. To choose the right size, place the mask over your face without using the strap and inhale through your nose. The mask should stay in place without leaking or slipping. If it does not, try a different size.

Position the Mask

Once you have the right size, position the mask on your face. The mask should sit comfortably on your forehead and cheekbones, with the skirt forming a seal around your nose and mouth. The strap should be on top of your head, not resting on your ears.

Adjust the Strap

Next, adjust the strap to ensure a secure fit. The strap should be tight enough to keep the mask in place, but not so tight that it causes discomfort or pressure points. Adjust the strap by pulling on the ends until the mask feels secure.

Adjust the Purge Valve

The purge valve should be positioned in front of your nose. You can adjust the position of the valve by moving it up or down on the mask. The valve should be at a comfortable height that allows you to easily exhale through your nose to clear water from the mask.

Check the Seal

To check the seal of the mask, put the mask on your face without using the strap and inhale through your nose. The mask should stay in place without leaking or slipping. If it does not, adjust the strap or try a different size.

Test the Purge Valve

To test the purge valve, place the mask on your face and press it firmly against your face. Inhale through your nose to create a seal, then exhale forcefully through your nose. The valve should open, allowing air to escape and water to be purged from the mask. If the valve does not open or if water remains in the mask, adjust the position of the valve or try a different mask.

Anti-Fogging Treatment

To prevent fogging, apply an anti-fogging treatment to the inside of the mask lens. This can be done by rubbing a small amount of toothpaste or baby shampoo on the lens, then rinsing it off with water. Alternatively, there are commercial anti-fogging sprays available that can be used. This treatment will help to prevent condensation from forming on the lens and ensure clear vision.

In conclusion, it is important to properly fit and adjust a purge mask to ensure clear vision, protection, and comfort while scuba diving. Choose the right size, position the mask properly, adjust the strap and purge valve, test the seal and the valve, and apply an anti-fogging treatment. With these steps, you can enjoy the benefits of a properly fitted and adjusted purge mask, including an enhanced diving experience and better protection for your eyes and face.
