I've used one of these for decades. They used to be sold by WaterPik. It uses a replaceable activated carbon filter that removes most bad tastes like fluoride from the water. Current models are not built as well as older models. It uses a kind of metal pot instead of the old solid plastic models. My new one already has a small leak. Installation is easy and only takes about five minutes. All necessary tools and fixtures are included. I use it to filter water for my Keurig coffee maker.
