Filter now installed

It came without any instructions in the box for installation. I had to go to the website and download a generic manual. The illustrations were small and did not give adequate description of the fastening hardware. I was able to figure out everything, but wonder if other people might find it difficult. I did run several gallons through the filter. The water is clear, and tastes good. I will see how long it lasts with the hard water we have.

have used now for 3 years

Filter works very well. I swap out every 12-18 months. This time the case is of a new design. Did not swap the case just the filter though. Is there as 3way to just order the filter and not the whole case, hanger and filter.? Great product
