What Is Nitrox?

Nitrox, also known as Enriched Air Nitrox (EANx), is a breathing gas mixture that contains a higher percentage of oxygen and a lower percentage of nitrogen than standard compressed air.


Because divers absorb less nitrogen while breathing enriched air, Nitrox can provide several important advantages when used properly.


These benefits have made Nitrox Certification one of the most sought-after specialty courses in recreational scuba diving.



Divers around the world choose Nitrox because it allows them to maximize their underwater experiences while supporting safer dive planning practices.

Why Is Nitrox Certification So Popular?

Nitrox is especially popular among divers who participate in multiple dives over several days, such as those on dive vacations, live-aboard trips, or guided dive excursions.


Some of the most common benefits include:

Longer No-Decompression Limits

One of the primary reasons divers choose Nitrox is the ability to enjoy longer no-decompression limits on many dives.



This means more time exploring reefs, wrecks, and underwater attractions before reaching dive profile limits.

Shorter Surface Intervals

Because less nitrogen is absorbed during Nitrox dives, divers may be able to reduce required surface intervals between dives when following proper dive planning procedures.



This can be especially beneficial during busy dive schedules.

More Efficient Dive Profiles

Nitrox can help divers maximize their time underwater while maintaining conservative diving practices.



Many experienced divers consider Nitrox an essential tool for recreational diving and travel.

Ideal for Dive Travel

Nitrox is widely available at popular dive destinations around the world. Having this certification can enhance your travel opportunities and allow you to take full advantage of dive packages that include multiple dives each day.



For divers who enjoy organized dive trips, Nitrox certification often becomes one of the most useful specialty credentials they earn.

Who Can Take the Nitrox Certification Course?

Nitrox training is accessible to many certified divers.


To enroll, students generally need to:

  • Be interested in continuing their scuba education

Whether you're relatively new to diving or have years of experience, Nitrox training can provide valuable knowledge that supports safer and more efficient dive planning.
