A retailer claims that Bobble water bottles:
Filter your own bottled water with this unique and patented set of two Bobble Water Bottles. An active carbon filter eliminates toxins and harmful chemicals such as chlorine and other organic contaminants from the water as you sip. The filter itself lasts for about two months, or at least 300 fills
removes chlorine and other organic contaminants from your drinking water.
uses active carbon filter technology to remove unwanted contaminants from your drinking water so it meets the standards of NSF International Standard 42, the standard that governs the quality of public and private drinking water. How it works is simple, really: as you sip, the water passes over the carbon filter where the negative ions of the contaminants are drawn to, and captured by, carbon granules. The result? Filtered water free of chlorine and other common organic contaminants--with no resulting plastic water bottle waste.
