The utilization of EAN32 and EAN36 mixtures is prevalent among recreational divers due to their optimal balance between oxygen content and nitrogen exposure. EAN32 contains 32% oxygen, which allows for a greater bottom time at moderate depths while reducing the risk of nitrogen narcosis. EAN36, with 36% oxygen, is advantageous for shallower excursions where divers desire a lower nitrogen load while still being mindful of maximum operating depth limits associated with higher oxygen percentages.

These mixtures are particularly suitable for recreational depths, allowing divers to enjoy longer dive times and minimized decompression obligations. The selection of these specific mixtures reflects a common practice within the diving community, highlighting their effectiveness in ensuring safety and maximizing the enjoyment of dives. Other mixtures listed, while also usable, do not reflect the same level of popularity or typical application in recreational scenarios.
