Help us end the trend of single-use plastic and drink ahead with a bobble that looks good on you and your planet. Made in the USA. How it works: 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. Lavender 2 pack
