                                                          Yes, brita filters work using a carbon or charcoal based filter that has been used in large-scale commercial and residential water purification systems for many years. If you have a culligan filtration system installed on your water lines you do not necessarily need the brita. If you have water directly from a municipal source it does help with water flavor.
