Hello Megan, Thank you for your inquiry The Ocean Quest Pacific Totally Dry Snorkel is probably the best snorkel on the market for a diver or a snorkeler. It easily attaches to the mask strap on the left side of your head and as long as the mouthpiece stays in you mouth, it will not allow water to enter the snorkel. With this feature, clearing the snorkel is not necessary.
