Pure Spa Cartridge Filter - NORTH

Maintaining Your Filter Cartridge

With proper care, a filter cartridge can last up to 12 months. Follow these steps:

• Check your spa manual for removal instructions.
• Clean every two weeks using a hose or cartridge cleaning tool.
• Soak in a non-foaming degreaser (e.g., dishwasher detergent or a proprietary cleaner) for at least an hour, preferably overnight. A cleaning powder like Pure-Spa Powder Filter Cleaner is recommended.
• Rinse thoroughly before refitting and allow to dry if possible.

Rotation Method

For optimal performance, we recommend rotating two cartridges: one in use and one on standby. While one is in service, soak the other in detergent for 2448 hours to remove residues, then let it dry fully before reuse. A dry filter performs better when refitted.

Will a similar-looking filter fit my hot tub?

Sometimes, a filter thats 510mm bigger in height or diameter will still fit, and many people use alternatives if their original is hard to find or discontinued.

Key considerations:

• Top of the filter: If your current filter has a closed top, you cant use one with an open top, as water will bypass the cartridge.
• Bottom thread: Must match exactly.
• Surface area: If the square footage is within 1015% of your original and it fits, its unlikely to cause issues.

Using a filter too far out of spec can restrict water flow, strain your pump, and potentially damage your hot tub. Always double-check before swapping.
