How do you know what size N95 mask you need?
The size of the mask is determined by the size of the rubber seal. The rubber seal should fit over the person’s entire face, including their nose, mouth, and eyes. The larger the person’s face, the large the rubber seal needs to be.
Are snorkel masks one size fits all?
Just like with clothing, manufacturers of full face snorkel masks use different sizes as their standard. Masks are sized as XS, S, S/M, M/L, and XL but it’s not until you take a closer look at individual size charts, and you’ll see small variations in these general sizes.
How do I know what size snorkel to get?
So how do you choose the correct size of a full-face mask? To work out the size that will fit you best, simply measure the distance between the bridge of your nose and the tip of your chin. You can do it yourself or ask someone to take the measurement.
How deep can you dive with full face snorkel mask?
With a snorkel mask you can dive to a maximum depth of 1 to 2 meters. The reasons for this are that the mask already presses strongly against the face at shallow water depths due to the trapped air. In addition, snorkel mask wearers cannot equalize the pressure (e.g. by holding the nose shut while breathing out).
Can you wear glasses under snorkel mask?
As dreamy as that may be, the short answer is that unfortunately no, you cannot wear glasses while snorkelling. The simple reason is that the earpieces of your glasses will break the silicon seal of the mask, allowing water to leak through.
