Bobble Magenta Replacement Filter, Set of 12

Great to have on hand as an extra or a replacement for an old filter, this Bobble replacement filter will fit on any Bobble water bottle. This set includes 12 individual replacement filters. With an activated carbon filter with a slight electro-positive charge, it attracts 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. Each filter is good for two months or 40 gallons of water, which is approximately 300 refills. Made in the USA, it is BPA free and FDA approved.
