Tootles uses an activated carbon filter to trap odor-causing molecules in farts. Activated carbon is commonly used in a wide range of applications, including: air purification, water filtration, food processing, sewage treatment, gas purification, amongst many others. Tootles has simply harnessed the power of activated carbon and used the same process of “adsorption” (not to be confused with absorption) to combat one of the most socially awkward experiences we all go through: farts.
