The APC APCC7509 Replacement Pool & Spa Filter replaces the FC-0124, Unicel 4CH-920 and Pleatco PSG13.5. Ensure that your spa or pool is clear and clean with the APC APCC7509. Made of Reemay spunbond pleated filter media equipped with thermally-bonded polyurethane caps and punched PVC pipe cores, this filter ensures durability and consistent flow. It features anti-microbial (Microban) technology, which prevents microbes like mildew, fungi, mold, and bacteria from growing. This technology is becoming the industry standard and is a part of every APC brand filter. Keep your pool or spa's water clean and your mind worry-free with this filter!

C7509 Replacement Pool and Spa Filter:

  • It is time to clean the filter when you notice a decrease in the pressure from your jets, or when the pressure in your filter tank increases by 8 psi from when the filter was newly installed.
  • In order to clean the filter, first remove it from its canister and use a garden hose to dislodge any debris between the pleats. Soak the 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 water.
  • Thoroughly rinse the cartridge with fresh water and reinstall it into the canister. Be sure to follow manufacturer's directions for installing the filter.
  • DO NOT use a high-pressure car wash wand, a stiff brush or acid wash to clean the filter cartridges as these methods can damage the filter media.
