   Any snorkel that you can’t clear in one normal breath is too long.
   You’ll need to inhale fresh air with each breath, and you can’t do that just rebreathing the air inside your snorkel.

   Depends on the diameter of the tube, but prolly more than 18" is too long.

   Get it?

   Beyond about 6 feet deep you can no longer suck air from the surface, so I’d advise to maybe get scuba certified.

   Humble, what are you "really" talking about?

   get one of the one way snorkels, the part on the surface only takes air in and when you exhale the air is directed by a one way valve out a different way to the side of your face

   It makes sense. The air you breathe out contains more CO2 (carbon dioxide) than the air you breath in. If you start breathing in before the air you have just breathed out has left the snorkel, you will be breathing in the same air again, containing more carbon dioxide, making it more difficult for your lungs to extract the oxygen.

   I know of people who have died after using a "fixed base" type (ie not handheld) CO2 fire extinguisher in an enclosed space. It is a very serious hazard. CO2 is not toxic like CO (carbon monoxide), but it suffocates you if it can’t be replaced by oxygen.

   It would be so easy if you could just take a very long hose and breathe in and out through it, but it just doesn’t work. I don’t know how long a snorkel can be, but I have never seen them longer than like 40 centimeters (16")
