As many of you already know, the Brita Fill & Go Bottle has been off the market for years now. While it claimed to be a great product, the development and design of the product was not well thought out. The old Brita Filter Bottle is now near impossible to find and the replacement filters are even more difficult to locate. The good news is water filter bottles and other personal water filters are now extremely popular and can be found in thousands of local stores and on the internet.
