Emergency Oxygen Respirator
CAIREN Oxygen Respiratory Device by Wooriwel Co., Ltd. is a breakthrough in personal safety, designed to enable secure, breathable air in critical situations such as fires and oxygen-deprived spaces.
Unlike traditional gas masks, which struggle to filter the diverse toxic gases emitted by modern fires, CAIREN offers a comprehensive solution. This device relies on an independent oxygen supply, bypassing limitations of filtration-based methods to ensure user safety in any air-compromised environment.
Compact and lightweight at only 270g, CAIREN is easy to store and carry, measuring roughly the size of a tumbler. Designed for speed, it can be put on in 10 seconds or less, even while wearing a hard hat—vital given that inhalation of toxic fumes often proves fatal within 30-40 seconds in modern fires.

The CAIREN device also includes unique wall-mountable packaging in a cylindrical case, making it as accessible as a flashlight in emergencies. This mountable feature enables quick and convenient access, reducing response time and allowing individuals to escape dangerous situations more efficiently.

Additionally, CAIREN’s design solves the challenges associated with conventional bulky respiratory devices, providing an agile, effective solution for various at-risk environments, from industrial sites to enclosed spaces.
Established in May 2020 by a team of KAIST experts, Wooriwel Co., Ltd. focuses on life-saving technology solutions, innovating in respiratory safety with CAIREN and other emergency oxygen products. With a mission to protect lives, Wooriwel has become a trusted supplier for major institutions globally.

Founder Baek Jong-tae, a recent recipient of the Innovation Medal at the Daedeok Science Town’s 50th-anniversary celebration, exemplifies the company’s commitment to advancing global safety standards. Wooriwel is well on its way to establishing itself as a global leader in life-saving respiratory devices.
