Your spa filter system was designed to work most efficiently with this 25 or 50 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 Waterway brand Top Load or In-Line Spa Filter System we sell. If this is not the filter system you have, click here.

The dimensions are 13 1/4 inches tall, 5 inches outside diameter, with a 2 1/16 inch center hole.

This item is not returnable, and carries a 90-day limited warranty.
