Seven signs it’s time
- Torn or frayed fabric: dirt goes straight through.
- Flattened or matted pleats that don’t spring back after cleaning.
- Cracked or separated end caps, or a crushed inner core.
- Short cycles: pressure climbs back up within days of cleaning.
- Cloudy water despite balanced chemistry and normal run times.
- Permanent discoloration or slime that soaking won’t remove.
- Age: more than about 3 seasons (pool) or 2 years (spa).
Make cartridges last longer
- Clean on pressure, not a calendar.
- Rotate two sets so each one dries fully.
- Degrease regularly: oils clog fabric faster than dirt.
- Keep water balanced; scale and high calcium shorten life.
