This message from a customer in Boston made our day. 🚴

Li Jiun commutes 40km every day through heavy urban traffic. After 1.5 years of long rides, she started noticing health effects — thick mucus, dry cough — but stopping cycling simply wasn't an option.

"I am grateful for the mask such that I can still enjoy long rides in a busy urban city."

— Li Jiun Chen, Google Review ⭐⭐⭐⭐⭐

That's why we do what we do. Every filter changed, every kilometre ridden safely — it counts.

Totobobo was a top performer in a test against another 4 types of masks including N95 mask. The test was conducted by the Queen Mary University of London.

As Delhi Chokes, New Study Finds A Reusable Mask Significantly Cuts Exposure to Toxic Soot Delhi AQI 400+: A Queen Mary University study simulating Indian traffic finds a reusable mask cuts diesel soot exposure by ~71%.

Throwback to 2008, Totobobo Maskinventor, Francis Chu joined Goska and Hervé on their Develotour adventure. As they cycled across Asia, they relied on Totobobo filtration masks — a simple yet remarkably effective solution for urban and rural air pollution.

From India to Thailand, Vietnam, and China, the duo wore their masks every day, changing the filters every six hours. Each used filter told a story, revealing the level of soot and dust they had just passed through.

By the time they completed their journey, they had gathered a striking visual record — a gradient of darkened filters, each marking the air quality of a different city.

That expedition was the first true long-distance test of Totobobo under real-world, high-exposure conditions. Goska and Hervé’s feedback proved invaluable, guiding refinements that made the mask even more practical for cyclists everywhere.
