I had the filters replaced on my reverse osmosis system. It was the first time. I probably could have done it myself but I am getting older and not as able to get into tight spaces under the sink. I also like the suggestion the technician made as to replacement intervals.
Products are proven. Very effective in providing the best water conversion for daily use. Brian...Mary and the whole team are professional and highly responsive. They do everything within their control to provide an excellent experience. I would provide a written or verbal reference to anyone considering Culligan Niagara.
