About Us
Innovating the future of sleep apnea care
5 GK Medical Ltd. is a Lindsay, Ontario startup revolutionizing the sleep apnea sector with cutting-edge, power-free technology.
Our story
An idea born at a cottage with no power
Existing sleep apnea devices rely on a constant power source. They can be cumbersome and restrictive, leaving patients without a dependable solution when electricity isn’t available.
The idea for Respire Lenis™ came from exactly that need. Our developer, diagnosed with sleep apnea, owned a cottage with no power — and no way to treat his condition there.
Our mission: to enhance the quality of life of people affected by sleep apnea through cutting-edge solutions and technologies.
