Product Information

The Filbur FC-2390M is a compatible replacement for the following pool and spa filters:

  • Rainbow/Pentair Dynamic 50, MICROBAN
  • Unicel C-4950RA

This compatible Pentair Rainbow Dynamic 50 spa filter features Microban technology to prevent microbes, such as bacteria, mold, fungi, and mildew from growing or reproducing on the spa filter media. The result is a compatible spa filter that matches or exceeds the quality of the original OEM, Pleatco, Unicel or Pentair spa filter cartridge. For a compatible filter cartridge without Microban, consider the Filbur FC-2390.

Filbur spa filters are made of Reemay spunbound polyester pleated filter media with thermally-bonded polyurethane caps and punched PVC pipe cores ensuring durability and consistent flow. Rest assured you are getting a compatible spa filter for the Unicel spa filters, but for a more economical price.

The Filbur FC-2390M product specifications:

  • Length: 13 5/16"
  • Diameter: 4 15/16"
  • Top: 2 1/8" Open
  • Bottom: 2 1/8" Open
  • Media: 3 oz
  • 50 square feet

Cleaning your Filbur Pool and Spa Filters

  • It is time to clean the filters 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.
