Spa Marvel Filter Cleaner

Spa Marvel Filter Cleaner pulls the oils, hair, dirt and grime out of cartridge filter fabric — without bleach or harsh acids. It's the filter-care match for the Spa Marvel system, and it works just as well on any spa running conventional chemistry.

How to use it: rinse the cartridge with a spray hose to knock off loose debris. Add two capfuls of Filter Cleaner to up to 20 litres of fresh water in a pail, submerge the filter, and soak overnight. Rinse thoroughly with fresh water the next day and, ideally, let the filter dry before reinstalling.

Why no harsh chemicals matters: bleach and acid-based cleaners clean fast but degrade the filter fabric and can carry residue back into the spa — the classic cause of a foam burst right after a filter clean. A surfactant-based overnight soak gets the same grime out gently.

Pairs naturally with Spa Marvel Water Treatment & Conditioner — clean the filter at the start of each 3-month treatment cycle. 226 g bottle.
