The Spark Behind CSpring: A Founder's Story

Every night, CPAP users face the frustrating hassle of their water chamber running dry. Even when filled before bed, the water often doesn’t last through the night, leaving users waking up with dry throats, disrupted sleep, and the annoying chore of a refill. It’s a small task that, over time, becomes a big disruption.

I’m Sebastian Cardenas, founder of CSpring in Roanoke, Virginia. As a longtime CPAP user, I know this struggle all too well. Each night I dealt with the same issue — waking up to a dry chamber, fumbling with water jugs, and trying to get back to sleep. But the worst part? It often woke my wife. As a nurse, she went to bed much earlier than I did, needing rest after long shifts. The noise of me opening the water chamber, refilling it, and clacking it back into place would disturb her sleep, too. What started as my problem became our problem.

Determined to find a solution, I scoured the market, expecting to find a larger-capacity water chamber or an automatic refill device. To my surprise, there was nothing available. That’s when I realized I had to solve this myself. Months of research, sketching, and collaboration with trusted engineers led to the creation of the CSpring One®️, and later, the refined CSpring Mk2®️ and the current CSpring Mk3®️.

The CSpring Mk3®️ is more than a product — it’s a solution born from necessity. It automatically keeps CPAP water chambers full, eliminating the nightly hassle and providing peace of mind. It’s something I personally use every night, and it has transformed my sleep experience. It’s an investment in your health and well-being.

At CSpring, our mission is to offer more than convenience. We’re here to help CPAP users achieve uninterrupted rest and wake up feeling refreshed. We owe our success to people like you who believe in our vision.

Here’s to 365 nights of better sleep — for you, your loved ones, and anyone who shares the journey of CPAP therapy.
