I change the main filters at home about once every 4 months. We have a well at home and the water in it is very good, but at certain times of the year it stinks a bit. Summer. These filters help keep my water system clean and reduce odors. that's a great value. My local fountain company charges $39.99 for the same product. and I have to drive 10 km to get it.
