Unlike other scuba diving gear, the Triton Scuba Mask is designed to offer you an indefinite stay underwater by stripping oxygen from the water around you like a real set of gills.

It’s based on a technology developed by a Korean scientist and employs a filter made up of threads woven together so tightly that whole water molecules aren’t able to pass through. A powerful micro compressor then pulls the oxygen through the filter and stores it in a small breath-sized tank.

According to Dvice: „The only limit to your stay under the waves is how long the next-gen battery that powers the compressor can keep your gills working. Supposedly, the battery in question is 30 times more compact than current off-the-shelf tech and can also charge 1,000 times faster.“
