How to Purge a Scuba Mask

Understanding how to purge a scuba mask is useful for a number of reasons. If the seal on your scuba mask is damaged, water can slowly seep in. If fog builds up inside of your mask, it is useful to let water in by pulling your mask slightly away from your face in order to clear it. The process of removing the water in both cases is called purging and it will leave your mask nice and clean.

Instructions

1. Look down in the water with your mask on.

2. Using your fingers, apply a bit of pressure to the top edges of your mask.

3. Exhale gradually through your nose while slowly turning your head to look upward. The air you breathe into the mask will force the water to exit from the bottom.

Tips & Warnings

• Store your scuba mask in a safe location--away from sunlight, which can damage the seal of the mask.
