* In ''Franchise/TheElderScrolls'' series, starting with ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', the series offers spells, potions, and enchanted items with the Water Breathing effect. These allow you to remain underwater without needing to surface for the effect's duration (or in the case of constant effect enchanted items, for as long as you have the item equipped).

* ''LightNovel/GoblinSlayer'': The Breath spell is normally just used to allow people to breathe underwater. However, Goblin Slayer demonstrates that [[ExactWords the spell accounts for all forms of water]] [[LookholeAbuse including snow and ice]], which allows him to survive being buried by an avalanche. He also utilizes the RequiredSecondaryPowers of the spell that protect the user from changes in temperature from water immersion to help his companions stay warm in a snowstorm.

* ''Series/BabylonFive''. Several races need to use breathers when going into the alien sector and several alien races need to use breathers to travel the rest of the station. Also, G'Kar has gills surgically added that allow him to breathe in alien atmospheres without a device. Lyta gets a set after being TouchedByVorlons.

* The Oz kit in ''VideoGame/{{BorderlandsThePreSequel}}'' allows the characters to breathe in the space filled environment.

* Modern Underwater gear generally falls into two categories, tanks of compressed air, and rebreathers. The former exhales directly into the water (leading to the characteristic bubbles), while the latter simply filters out the [=CO2=] and adds oxygen so the nitrogen can be re-used. It still has some gas, so it's only a partial example. Older designs simply pumped air down from the surface using a tube.

* Literature/DocSavage not only had diving suits more advanced than anything available in RealLife at the time, but also 'oxygen tablets' that supplied oxygen directly to the blood and allowed the users to survive underwater for about two hours.

** The ''Far Harbor'' DLC adds the ''Franchise/BioShock''-style Rescue Dive Suit.

** The Aquaboy/Aquagirl perk allows the Sole Survivor to indefinitely remain underwater.
** The PowerArmor increases the length of time you can stay underwater, [[WalkDontSwim but you can no longer swim in it]].

** The PowerArmor also now grants underwater breathing, [[WalkDontSwim but you can no longer swim in it]].

* ''Toys/{{BIONICLE}}'': the [[MaskPower Kaukau and Kaukau Nuva]], a.k.a. the Masks of Water Breathing. These filter oxygen out of the water and allow the wearer to breathe.

* The animated ''WesternAnimation/{{Flash Gordon|1979}}'' had an episode with featuring a literal ArtificialGill: It was a metal collar with gills, that also prevented the wearer from breathing outside of water.

* In ''Franchise/TheElderScrolls'' series, starting with ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind Morrowind]]'', the series offers spells, potions, and enchanted items with the Water Breathing effect. These allow you to remain underwater without needing to surface for the effect's duration (or in the case of constant effect enchanted items, for as long as you have the item equipped).

* Later games in ''Franchise/TheElderScrolls'' series have spells and enchantments for this available to players.

* ''{{Wizard 101}}'' has underwater breathing potions early in the game to allow access to a street that is completely underwater. However, due to the game mechanics, players can teleport to this area without adverse effects.

In fiction, characters may for whatever reason need to stay underwater for an extended period of time. In RealLife, this can be accomplished with SCUBA gear for short periods (about 1 hour) or rebreathers for much longer periods -- however, these real world devices are bulky, require a lot of training (especially rebreathers), and are priced well beyond many peoples' means.

** On Admiral Ackbar's planet Mon Calamari (seen in ''[[Literature/JediAcademyTrilogy Dark Apprentice]]''), they have flexible, jelly-like breathers you slap over your nose and mouth and it filters the water into oxygen. The Yuuzhan Vong in the ''Literature/NewJediOrder'' series have a similar creature called a gnullith that covers the nose and mouth, and extends down the windpipe to interface with the lungs directly. It's incredibly useful, even because it doesn't need recharging of any kind, and unlike their other biots, gnulliths cause no pain or discomfort.

* The O2 mask in ''Franchise/RatchetAndClank'' allows Ratchet to survive in toxic atmospheres,underwater and even space with unlimited air supply.

Obviously, these concerns would bog down most fantasy or science fiction narrative. The solution? The Artificial Gill: A device that enables a character to swim underwater without worrying about the OxygenMeter, unless the device runs on air tanks. These are used to find and explore UnderwaterRuins and the UnderwaterCity.
