The Filters Fast® FF-0351 is the correct replacement pool and spa filter for the Rainbow 25393. By using three essential components - spunbound polyester pleated filter media, thermally bonded polyurethane caps and punched PVC pipe - the FF-0351 provides lasting durability and continuous, crystal-clear water flow. While the FF-0351 meets and/or exceeds compatible OEM pool filters in performance and longevity, it also naturally prevents microbes, such as bacteria, mold, fungi, and mildew from growing or reproducing. Even when you backwash your pool's filter system, the FF-0351 can handle large amounts of dirt and waste water with ease.

Cleaning your Filters Fast® FF-0351 Filter

  • It is time to clean your spa or pool filter cartridge when you notice a decrease in the pressure from your jets, or when the pressure in your pool filter tank increases by 8 psi from when the filter was newly installed.
  • In order to clean the pool filter, first remove it from its canister and use a garden hose to dislodge any debris between the pleats. Soak the pool filter in commercially prepared filter cleaner, or spray with the same to remove organic material and oils. To remove stains soak overnight in a solution of one quart bleach and 5 gallons of water.
  • Thoroughly rinse the pool filter cartridge with fresh water and reinstall it into the canister. Be sure to follow manufacturer's directions for installing the replacement pool filter.
  • DO NOT use a high-pressure car wash wand, a stiff brush or acid wash to clean the pool filter cartridges as these methods can damage the filter media.
