Great replacement for my BigBlue filter. Moved to a new house by a well with one of these filters. I think it had to be changed after 1 1/2 years in the house. The boy was right! Phew, it was really dirty there. Now that I've found these affordable substitutes, I'll be changing them quarterly and saving the water we bathe in, wash our clothes, and even drink a lot cleaner! Also seems to be catching a lot of rust. The process is very good.
