Altitude Generators

Hypoxic generators, also known as altitude generators, are devices designed to simulate high-altitude conditions by reducing the oxygen content in the air. Our generators have gained popularity in the fitness and health communities due to their various potential benefits. Choose from our generators and combine with a tent or make use of the mask included.

Training in hypoxic conditions can boost metabolism and aid in weight loss or management.

Cardiovascular Benefits

Athletes often use hypoxic generators to simulate high-altitude training, which can improve cardiovascular endurance and performance.
