A startup backed by USD 10 million wants to make lung health a daily habit. Its first product, L Max, launches in spring 2026.
Wellness culture has built entire industries around sleep, gut health, hydration and exercise recovery. The lungs, despite powering every one of those systems through oxygenation, have largely been left out of the conversation, unless something goes wrong. Climatic, a New York-based startup that raised USD 10 million in seed funding earlier this year, is betting that's about to change.
Its first product, L Max, is a daily inhaled dry powder made from five all-natural ingredients, including sodium bicarbonate, citric acid and the plant extract forskolin. One deep breath each morning, the company says, is enough to support the lungs' natural ability to clear out mucus, pollutants and fine particulate matter. In vivo studies conducted with Mount Sinai Medical Center of Florida showed that a single administration improved mucus clearance by more than 50%, with effects observed within minutes. A placebo-controlled, double-blind clinical study is now underway.
Climatic is trying to create a new category, positioning daily lung care as a health habit on par with taking a probiotic or tracking sleep. L Max is designed for people who already count their macros and monitor their heart rate variability, but have never thought to take a proactive approach to respiratory function. A five-week trial with endurance athletes found that 98% reported easier breathing during workouts, with an average 6% improvement in time trials. Early access to L Max begins on April 20, with a broader launch planned for late spring 2026.
TREND BITE
The WHO estimates that 99% of the global population breathes air that exceeds its quality limits, containing unhealthy levels of fine particulate matter and nitrogen dioxide, yet lung health remains one of the few major organ systems without a mainstream preventive care category. Climatic's play is to close that gap by applying the same playbook that transformed probiotics from a niche concern into a grocery store staple. The timing isn't incidental. Worsening air quality, wildfire seasons that now stretch across continents, and a growing fixation on longevity metrics like VO2 max are making respiratory health harder to ignore. Whether L Max delivers on its clinical promise remains to be seen, but the white space it's targeting is real.
