Sanso is an holistic approach towards our health. Indoor pollution is on the rise but not all are aware of its danger. We have the tendency to spend 80% time indoor not knowing what type of air we are breathing. Throughout a simple kit and an all-natural solution, Sanso has the goal to let you take a deep, and clean, breath. The air filters are made out of bamboo charcoal, a natural air purifier, discovered in Japan in the early 10000 AC by the Jomon population, which is fully biodegradable and contains no harsh chemicals.
