We purchased our from Better Water Store. Once you have removed your old shower head you will be able to replace it with the new shower filter. These filters give you the same quality water pressure, and in some cases better than what you had with your shower head. The biggest bonus of these easy to install shower filters is that you will come out of the shower feeling like a whole new you. Once the filter has removed harmful chemicals that have been added to your water, a you will have that shower fresh feeling that you haven’t truly experienced until you tried one.
