I recently moved a town that gets its water from a lake & then chlorinates & fluoridates it. Plus who knows what other contaminants run in. YUCK!!! This filter cleans up the water beautifully. It tastes great. I love the constant flow as opposed to reverse osmosis units. I did have a plumber install it so I don't know how easy it is to connect, but he had no problem. I live in an apartment so I like that I can take it with me if I move. Now I can rest easy knowing that I am drinking clean, healthy water. I am so happy I found this product & will certainly recommend it to everyone!
