The Bullfrog® 10-2870 filter cartridge is a genuine OEM Microban®-infused replacement for Bullfrog® spas produced from 2003 onward (excluding STIL models).
It provides 35 square feet of pleated media for efficient filtration and exceptional water clarity.
The filter integrates Microban® antimicrobial protection to resist mold, mildew, and bacterial growth on the media surface.
It features a closed top semi-circular handle and a 2″ SAE coarse threaded bottom for secure fit.
This cartridge replaces earlier models such as 10-1035 and 10-2785 and is compatible with many alternative filter codes (e.g. Pleatco PBF35, Unicel 8CH-950).
Regular use and timely replacement of this cartridge help preserve spa pump and heater life while maintaining water quality.

Directions

Turn off power to the spa and stop all pump operations before servicing the filter.

Remove the filter housing lid or access panel to expose the cartridge.

Twist or pull out the existing filter cartridge and discard (or clean if reusing).

Insert the Bullfrog® 10-2870 cartridge into the housing, aligning threads if present.

Secure the housing lid or panel and ensure it is properly seated.

Turn spa power back on and run the system to confirm proper water circulation.

Rinse or clean the filter regularly (every 2–4 weeks) and replace annually or sooner depending on water quality.
