Why can be a full face snorkel mask dangerous?
While breathing we produce carbon dioxide. While any activity, your body needs more oxygen and you breathe faster and shallower. If this happens in a closed space like with a full face mask on your head, you don’t exhale deeply enough to push the used air out of the snorkel mask/tube and start breathing in the bad air that contains more carbon dioxide. If you breathe in used air full of CO2 leads to headache, dizziness, and unconsciousness. CO2 can build up in wrong-designed normal snorkel tubes too… This problem can occur not only with full face masks, having the wrong equipment can always lead to dangerous situations.
This sounds scary, but don’t start worrying. If your snorkel equipment is well-designed and tested, it is safe to use. Therefore we always recommend buying high-quality snorkel gear from well-known trusted brands. Luckily also manufacturers of full-face snorkel masks have taken this into account and designed the masks accordingly: they are divided into a breathing and a looking part. Breathing part seals the mouth and nose off from the viewing part. On the top of this part, you find little valves which only let in fresh air, so if the design is correct and silicone seals perfectly, bad air that contains carbon dioxide is forced to flow out of the snorkel on the side channels of the mask. In order to get perfect air circulation and no leakage, it is important to know how to choose the right full face snorkel mask size.
Full face mask manufacturer breathing test results
Since full face masks are new on market, little information available on them and it became an urgent matter to state if they are dangerous or safe to use. So far the 2 biggest manufacturers, Decathlon-Subea and HEAD/Mares commented the full face snorkel mask dangerous question and made information public on standards and tests. The inventor of full face masks, Decathlon provided us with information in e-mail, moreover their Subea safety statement is available on their website as well. HEAD/MARES joined Hawaii authorities and investigated various types of masks focusing on measurement of potential full face mask CO2 buildup.
HEAD Sea Vu Dry official announcement
“While there are no specific standards for testing of full-face snorkel masks, HEAD referenced two European Union Norms, the EN250, and EN14143, standards widely used in the scuba diving industry and also adopted by US authorities such as NASA for the testing of full-face scuba diving masks. CO2 buildup measured on the HEAD full face mask is at around 50% of the maximum allowed limits set by EN250 at a breathing rate of 10 liters per minute (slow and calm breathing). Around 20% of the maximum limit when breathing at a rate of 62.5 liters per minute (e.g. breathing heavily with still deep breaths in a panic situation). In other words, the higher the stress level, the higher the breathing rate, and the better the mask performs.”

When is a full face snorkel mask dangerous?
…if it is fake, does not have patented design
…people don’t use it correctly
How do I mean fake full face snorkel mask dangerous?
The original manufacturer spent ages on designing, testing full face snorkel masks involving the best engineers and designers. Unfortunately most products nowadays just cheap copycats without any technical background and knowledge. We heard about sellers who just buy a few thousand masks from (usually) Chinese wholesale sites, put their logo on them and start selling as their own product. Yeah, they are those sellers who enter the market with attractive prices, make a good profit than disappear. No, don’t get me wrong, the problem is not that the product is made in China. High-quality product made in China can be as good or even better than a product made in Europe, Australia, USA or anywhere in the world. I just use China as an example. The problem is when manufacturers don’t own a patented, tested design, well-established process how to produce safe products. Instead just copy the outside design of a successful item and flood the market. Of course, customers get caught by lower prices, everybody loves to save money, right? Me too! But please collect information and think before the purchase, especially if it comes to our own or family’s safety.
How to use your full face snorkeling mask correctly?
Full face snorkel masks can be used for easy surface snorkeling only! Easy surface snorkeling means you are rather just floating on surface than swimming. If you need to swim against waves, currents, or intensively for any reason, better use normal snorkel gear. If you experience any difficulty, find your breathing heavy, remove the mask immediately. Never dive with full face masks! I know, you often see on photos people dive with them. Worse, that even the companies that want to sell the masks use these type of pictures… But this is a BIG NO, they can be used on surface only. If you ever felt claustrophobic, go for a regular snorkel mask with tube. In order to have pleasant, safe experience, follow the basic rules of safe snorkeling!
What is our opinion?
It is not a secret, we are getting requests regularly from full face mask distributors to promote their products but we refuse these. The reason is simple: you could read in our Easybreath Full Face snorkel mask review that we tested the product, but we stick to our classic snorkel mask + tube combo. We use to dive deep to be able to observe marine life better, take photos, so using a full face snorkel mask is not an option for us. We don’t participate in promoting products we don’t know and use. Although you can see we included some full face snorkel masks in our Snorkeling Shop and also mention some in our articles. Based on feedback and tests, these masks are safe and reliable if you use them as you should, made by trusted manufacturers.
