Maintenance Tips:

  • Rinse your spa/hot tub filter out once a month to remove debris.
  • Clean your filter with a filter cleaner each time you drain and refill your spa to remove any stuck on oil, lotion or detergents.
  • Keep a spare filter cartridge on hand to save time and money.

How to properly clean your spa filter cartridge:

  • When there is a visible decrease in pressure coming from your return jets or when the pressure gauge on your filter tank reaches 8 psi after a new cartridge is installed, then it is time to clean your filter. 
  • First, remove your spa filter from its canister, then use a garden hose to loosen any debris wedged in between each pleat. Avoid using a stiff brush or high-pressure washer that could damage your filter media.
  • Soak your Filbur FC-2372 filter in a commercially prepared cartridge cleaner to remove any oil and organic material. For stubborn stains, soak your filter cartridge in a solution of one quart household bleach to 5 gallons of water overnight. Exercise extreme caution when handling chemicals.
  • Rinse your Filbur spa/hot tub filter with clean water, then reinstall it into the filter tank. It is crucial that you remove or reinstall your filter, as well as restart your filtration system according to the manufacturer's instructions.
