Old & Dirty Filters = Costly Service Calls

We highly recommend that you replace your filters at least once per year and clean them once per month. The dreaded FLO error message is a direct result of dirty and over-the-hill filters. In the long run, it is much cheaper to regularly replace your spa filter cartridges than have to pay for a new pump or heater.
