Pleated cleanable filters: Clean the filter cartridge at least once a month by soaking in a solution of 16oz of Filter Clean and 4 gallons of water, then rinse very well with fresh water. Replace the filter cartridge every 12-18 months. Instant Cartridge Clean can be used as a pre-treatment before a soak, or if a full soak is not possible.
Do not soak disposable Microclean filters: With a 2 part filter system, the small Microclean filter or Microclean insert should be replaced every 3-6 months. For the pleated cleanable filter, use the above instructions.
Full size Microclean filter: Dispose after 6-9 months as it is not cleanable. Replacement times for Microclean filters will vary based on water conditions and bather load. Rinsing periodically with clean water may help extend the life of the filter.
Hot Spring® Tri-X filters: Should be placed into the dishwasher (without soap or other additives) to remove surface debris once a month. We recommend soaking the Tri-X filter using Filter Clean to remove minerals and oil buildup every quarter.
