I have a basic wal-mart pool. 18ftx48. Upgraded pump to 2500GPH Intex. I have to complaints. It works very well for me. I do not mind buying or cleaning the Type B filters. But I came across a ReUsable Filter on Amazon I wanted someone else thoughts or advice. I have never used a reusable filter for this. What I found was...OrcaFilter Reusable Type B filter from Amazon. $54.95. I really do not know what I spend on filters. I order on-line from Rural King. Got them for $3 and bought 3 this last time. They were $5.99 in the store.
