bobble has an activated carbon filter which has a slight electro-positive charge, making it attractive to chemicals and impurities. as the water passes over the positively charged carbon surface, the negative ions of the contaminants 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 or exceeds NSF International Standard 42 for chlorine, taste and odor reduction. for best results we recommend changing your filter after 2 months or 150 liters. filter for use with bobble only.

bobble filters are available in singlepack and twopack

warning: do not use where water is microbiologically unsafe or of unknown quality.
