How Long Does a Pool Filter Cartridge Last?
If you own a pool on the Gold Coast, you already know how much our sunshine, salt air, and summer storms can affect your pool water quality. One of the biggest factors in keeping that crystal-clear, healthy water is your pool filter cartridge — but how long does it actually last?
How a Pool Filter Cartridge Works
Your pool’s filter cartridge sits inside the filter housing and traps dirt, oils, sunscreen, and debris as water circulates through the system. The cartridge’s pleated fabric acts like a fine sieve, catching particles down to a few microns in size — much smaller than the human eye can see.
This means your filter cartridge does the heavy lifting to keep your water sparkling and safe for swimming.
How Long Should a Filter Cartridge Last on the Gold Coast?
On average, a pool filter cartridge lasts between 12 and 24 months. However, Gold Coast conditions — warm temperatures, frequent use, and wind-blown debris — can shorten its life.
Factors that affect lifespan include:
Pool usage – the more swimmers, the faster the cartridge clogs
Water balance – high calcium or incorrect pH can damage the pleats
Cleaning habits – over-cleaning, using a pressure washer or using harsh chemicals can weaken the fabric
Environmental debris – leaves, pollen, and sand from coastal breezes add strain
With good care and professional maintenance, a quality filter cartridge can easily last up to two years in our local climate.
How to Keep Your Filter Cartridge in Top Condition
Proper maintenance can dramatically extend the life of your cartridge. Here’s what we recommend:
Rinse every 2–4 weeks using a garden hose or cartridge cleaning tool to remove surface debris.
Deep clean every 2–3 months using a specialist cartridge cleaner to dissolve oils and calcium buildup.
Avoid pressure washing — it can tear the pleats and shorten lifespan.
Keep water balanced — maintaining correct pH (7.2–7.6) and calcium hardness prevents scale buildup.
Use a skimmer sock — it helps catch fine debris before it reaches the filter.
Perfect Balance Pool Care can handle all of this for you, ensuring your system is maintained to manufacturer standards.
Signs Your Filter Cartridge Needs Replacing
It’s time to consider replacement when you notice:
Water isn’t as clear as usual, even after cleaning
Filter pressure stays high after rinsing
You’re cleaning the cartridge more often with less effect
The pleats look frayed, cracked, or discoloured
The fabric feels soft or the end caps are deteriorating
Ignoring these signs can put extra strain on your pump and reduce circulation efficiency.
