How will I know when it is time to replace my filters? My tub is two years old, and it is used very lightly. I have been cleaning the filters in the dishwasher every 3-4 months. Filter replacement is not a trivial endeavour, as my Grandee has 5 Tri-X filters at $50 a pop!
As a corollary, is dishwasher cleaning adequate, or would alternating with overnight soaking in a filter cleaner prolong the useful life of the filters? Seems like I would need a bottle of filter cleaner for every two filters, and it would be somewhat of a PITA to find a large enough vessel to do them all at once.
