The Filbur FC-1613 Sonfarrel 40 Pool & Spa Filter is a compatible replacement pool and spa water filter cartridge built with reinforced PVC center cores that evenly distribute stress and have increased debris loading. This Filbur pool filter's polyester media is both durable and efficient.

The antimicrobial end caps of this compatible Sonfarrel 40 filter are reinforced for added strength and specially treated to reduce bacteria and mold build-up. In addition, this Filbur spa filter's support bands are wider, resulting in higher break-resistance.
