I have the cheapie paper filters in my pump. I figure it costs me 1.50<>2.00 to clean a filter (6 -8 cleanings from a 12.00 bottle of cleaner) The throwaway wally world filters cost about 6 bucks, the better ones at the pool place are about the price of the cleaner. How many times can I clean the filters before they are no good? The filter media is intact - no rips, tears, etc. I have 4 filters and rotate them every 5 days or so and I clean two at once.
