bobble has an activated carbon filter which has a slight electro-positive charge, making it attractive to certain chemicals. as water passes over the positively charged carbon surface, the negative ions of these chemicals are drawn to the surface of the carbon granules.

carbon filters require very little maintenance and are perhaps the most powerful chemical absorbents known to man. bobble’s carbon-based filter meets NSF International Standard 42 for chlorine, taste and odor reduction. for best results we recommend changing your filter after 2 months or when it’s filtered 40 gallons/150 liters. filter for use with Classic bobble or bobble Sport only.
