Water Bottle Filter

[disneychrista]

Last time I went to WDW I had a bad reaction to the water (major intestinal distress) and was forced to purchase bottle water. I could not drink any tap water, fountain beverages, coffee, etc. I am looking to buy a water bottle with a build in filter that removes sulfur. A quick search says that the Brita filter will not work for this. Anyone buy & use a water bottle filter that worked to remove the sulfur and the unwanted side effects?
