This carbon based filter for the biodegradable bottle removes chlorine AND organic contaminants from regular municipal tap water.

The filter is good for about 90 uses, which roughly equals 45 quarts or 12 gallons. You can let it dry out between uses if you use it sporadically.

When I travel, I squeeze tap water through this bottle into my 1 liter drinking bottle, then ionize and alkalize the water with water ionizer sticks. I create my own, filtered, high ph, ionized water on-the-go for water better than money can buy!
