Hayward Replacement Filter Element

This is the replacement filter cartridge for the Hayward In-Line spa filter system we sell. If you are looking for some other filter, click here.

This filter cartridge fits the Hayward C225 Micro Star Clear Filter System. This is a 25 square foot in-line filter, Unicel part number C4325.

Your spa filter system was designed to work most efficiently with this 25 square foot heavy duty Unicel filter cartridge. While routine cleaning can extend the life of your filter cartridge, algae, suntan oil, body oil and other contaminants will rapidly clog the tiny pores of the filter membrane which drastically reduce the effectiveness of your filter. We recommend cleaning your cartridge twice a month and replacing it every 3-4 months.

This filter cartridge is not intended for use in any other spa filter system than the Hayward Micro Star Clear Filter System we sell. If this is not the filter system you have, click here.

The dimensions are 11 7/8 inches tall, 4 5/8 inches in outside diameter with a 2 1/16 inch center hole. This item is not returnable, and carries a 90-day limited warranty.
