Our Story
CUOLL – where dreams begin. Our extraordinary journey started with a singular vision: to redefine bath filtration for a healthier, more sustainable world. Our founder, a passionate innovator with a deep love for clean water and nature, embarked on this mission not from the comfort of a grand enterprise but from a modest home studio.
Unlike traditional filtration brands born from corporate legacies, CUOLL was built on relentless curiosity, perseverance, and a determination to improve lives. The founder, once troubled by the harmful chemicals and pollutants in everyday water, imagined a solution that could transform a simple bath into a pure and rejuvenating experience.
Those early days were filled with challenges—endless prototypes, late nights fueled by hope, and personal deliveries of the first filters to local stores. The founder would often speak with early customers directly, listening to their stories and learning from their experiences. These interactions became the backbone of CUOLL's mission: to make high-quality bath filtration accessible to all while protecting our planet.
