The water we used had become weird last week, so I bought this filter to pury the water. Actually I didn't konw how to choose a filter because I had never used one before. So I asked my friend ans he recommended this one to me. I would recognize that this one really works as described. The smelly odors of the water had gone. The water seems to be cleaner and It is so nice for a shower. I wonder if it works on our kitchen. I really want to install one in the kitchen but this one seems to only use for bathing. Buy the way, this filter fits well and simple to install. I am going to make a second order and installl one on the upstairs. So helpful and healthy.
