Wellis Crystal Filter Cleaner
What it does
Most filter clogging is caused by body oils, sweat, and lotions — not visible debris. These oils coat the filter media and reduce flow. Crystal Filter Cleaner emulsifies and flushes them away.
When to use
- Monthly: overnight soak for a deep clean.
- After a heavy bather load (parties, rental turnover).
- If you notice reduced jet pressure or cloudy water that won't clear.
How to use
- Remove the cartridge filter from its housing.
- Rinse loose debris with a hose.
- Submerge in a bucket of warm water + Crystal Filter Cleaner per the bottle dilution.
- Soak overnight.
- Rinse thoroughly with clean water until all suds are gone.
- Allow to dry before reinstalling — or use a spare cartridge while this one dries.
Replace the cartridge every 12–18 months even with regular cleaning.
