Bests & Worsts Reviews from Amazon

Just received my bottle for a trip to Brazil in April and my main purpose for the bottle is to filter the tap water there. I love the design of the bottle and it's simplicity but like some other Reviewer's made mention, my bottle aslo has a very strong chemical taste like you are drinking from a brand new vinyl garden hose (was using tap water) and that taste was not going away even after several refills (felt like I was poisoning myself with that chemical taste). It's not the bottle but the filter that is producing the strong chemical taste. The bottle holds 650ml of water (about 20 ounces) and there are measurement marks on the side of the bottle. I decided to try putting 200ml of white vinegar in the bottle and filling the remainder with water and inserting the filter (which is attached to the cap) into the solution and let is sit for a few hours. The result was that about 90% of the chemical taste had disipated. I also try adding Mio flavored water enhancer to the water which greatly improved the taste until the reaming 10% of the chemical taste is gone. Also note that though the filter will remove micro organisms, it does not state anywhere that it will remove chemicals from the water such as fluoride, chlorine and other contaminants. Overall, a good design and hoping it's works as good as other Reviewers state. UPDATE 06/15: Did buy 3 more bottles for family members and none of those bottles had the chemical taste. These did work great when we traveling in Brazil using regular tap water, water tasted good with no illnesses.
