Bullfrog® @Ease® Simplicity™ Housing Assembly (2-Piece Clamshell) – Part #10-04669

Turn off spa power and ensure the circulation pump is off.

Remove the JetPak or access panel to expose the filter housing area.

Remove the existing filter cartridge and the old housing assembly.

Inspect and clean the mounting surface, O-rings, and gaskets for debris or damage.

Position the two halves of the new housing (part #10-04669) around the filter cartridge and align tabs and hinge features.

Secure the housing halves together as per the factory configuration.

Reinstall the filter cartridge, close the access panel, restore spa power, and verify correct flow and no leaks.

Q: Which spa models is this housing compatible with?

A: Fits Bullfrog® Spas that use the Simplicity™ Filtration System — specifically M Series, Swim Series, and 2023+ A Series models.

Q: Do I need this housing if my filter cartridge fits and works fine?

A: Only replace the housing if it is cracked, warped, leaking, or part of a retrofit to the newer Simplicity™ system.

Q: Is this housing backwards compatible with older filter systems?

A: No — the Simplicity™ housing (part #10-04669) is designed for the flat-style cartridges and is not compatible with legacy cylindrical filter systems.

Q: What material is the housing made of?

A: It is constructed from high-density polymer designed to resist spa chemicals, heat, and repeated service cycles.

Q: How often should the housing be replaced?

A: Replace the housing only when it shows signs of damage or poor seal fit. Proper inspection during cartridge change-out will reveal when service is required.
