You know what's sucky about using a shower filter? You have to change it every few months. Every time you have to take the filter out, clean it, and put it back in, you're reminded of how much work goes into taking care of your family. Well, we figured that out and created the Universal Faucet Filter. This is the one filter that fits all your faucets! It comes with a replacement cartridge so if you start seeing water come through slowly or not at all, just replace the cartridge and watch as the water rushes through in seconds.
