Application scenarios

Two worlds, one science of air

Whether the goal is sheltering from contaminated air or training the body to thrive on less oxygen, it comes down to precisely controlling the atmosphere you breathe.

Civil defence shelter

Survival shelters, bomb shelters and fallout protection for households and industry. Shelters are also widely used in industrial settings against technological accidents and severe weather events common across the United States.

Performance Hypoxia-based training

Hypoxia-based training

Hypoxic chambers, rooms and tents, plus hypoxic training and sleep protocols. By precisely reducing oxygen, low-oxygen training simulates altitudes of roughly 1,500–3,000 m — bringing high-altitude adaptation to the gym, clinic and home.

Brizz devices

From boosting athletic performance to enabling high-altitude adaptation and supporting rehabilitation, the multi-scenario adaptability of Brizz devices addresses the core needs of diverse user groups.

Brizz 1 — Altitude generator

Draws in ambient air and reduces its oxygen level on demand, supplying hypoxic air to a tent, room or mask for precise, repeatable training.

Brizz 2 — Mask system

An instant simulated-altitude experience without tents or chambers — ideal for HIIT, strength and cardio, indoors or on the move.

About us

Two decades of studying what we breathe

For more than twenty years we have studied the effects of elevated carbon dioxide levels on the human body. This website provides evidence-based information on CO₂ and other airborne contaminants — explaining which air pollutants may pose health risks, and how their negative effects can be reduced or, in some cases, minimised altogether.
