Are full face snorkel masks safe?

What problems could using a full face snorkelling mask cause?

The Problem:

The full-face design of these snorkel masks can allow CO2 to build up in the area that you are breathing from. If this air isn’t circulated out of the mask properly, the CO2 buildup could cause dizziness, nausea, or even unconsciousness.

Are full face dive masks safe?

Unfortunately they are quite dangerous and can quickly lead to drowning upon failure. High quality masks don’t immediately pose a huge risk, but there is no guarantee how long they will continue to work. This is why the safest choice is to steer clear of full face snorkel masks altogether.

How long do snorkel masks last?

Snorkeling masks will typically last 3-5 years if used frequently. They may last up to 10 years when in dark and dry storage, but sun, sand and saltwater result in deterioration of the silicone around the face skirt when used often.

Can you equalize with full face mask?

Both masks have a piece of rubber right underneath your nose inside the mask. If you push the mask up, the rubber blocks your nostrils and you can equalize.
