Hi I have the 5 stage ph/ionizer countertop model. I am trying to figure out how to replace the filters. Do you have a diagram or instructions for how to do that? Thanks for your help!
What is the life span of the filters below?
How do you clean and/or replace filters below?
Can any of them be back-washed, if so, how does one back-wash the filters?
