The BRITA Fill & Go Water Filtration Bottle filter removes bad tastes, odors and chlorine that may be present in your tap water. For best results, it’s important to change the BRITA water filter on BRITA portable bottles every 15 gallons or every two to three months, whichever comes first.
To let you know when it’s time to change your filter, BRITA portable bottles feature a convenient filter change reminder calendar that is applied to your bottle.

-Unfortunately Brita has discontinued production of the Fill & Go water bottle system.
