Frequently Asked Questions

What spas is this filter cartridge compatible with?

This cartridge is a direct replacement for Bullfrog and Signature Spas models that use the 50 sq ft FC-FCD150 filter element. Check your existing cartridge dimensions — 145mm height x 200mm diameter with a 51mm internal spigot — to confirm compatibility.

How often should I replace my spa filter cartridge?

As a general guide, rinse your filter every 4–6 weeks, deep clean it every 3–4 months, and replace it every 12–24 months depending on usage and water chemistry.

Can I clean this cartridge rather than replace it?

Yes, pleated cartridges can be rinsed with a hose and periodically soaked in a cartridge cleaning solution. However, once the pleats are damaged or the cartridge no longer holds its shape, replacement is recommended.

What is the thread type on the spigot?

The bottom spigot features a coarse thread for a firm, leak-free connection to the filter housing base.
