“We underestimate how many people live in the gray zone of respiratory health — not sick enough for a diagnosis, but not operating at full capacity either. Small changes in lung function can meaningfully affect performance, recovery, and wellbeing. The beauty of what Climatic is doing is bringing those invisible shifts into view, giving people real feedback on their respiratory resilience outside of a clinic.”

    Training for a marathon? You need this.

    I can’t explain how much Climatic has changed my breathing. I finally feel like I can take one huge deep breath without issue. I have struggled with season allergies for most of my life and have never really found a good solution for everyday, until now! I would recommend this product to anyone.
