Your spa pool is your sanctuary—a place to relax, unwind, and enjoy crystal-clear water. But to keep it that way, regular spa filter maintenance is essential. Your spa filter plays a crucial role by trapping dirt, oils, and debris, keeping your water clean and your spa running efficiently. Here are some simple tips to keep your spa filter in top condition—and why it’s so important not to skip this routine.

Quick Spa Filter Maintenance Tips:

1. Rinse your spa filter every fortnight.
2. Apply Filter Cleaner every fortnight to remove oils and grime.
3. Replace your spa filter every 12 months.
4. Watch for signs of filter failure: cloudy water, weak jets, visible debris.
5. Clean filters = better water quality and lower chemical use.

1. Clean Your Spa Filter Every Fortnight

A quick rinse with a garden hose every two weeks helps remove trapped dirt and debris. However, that’s just the first step. To keep your spa filter working at its best, apply a dedicated Filter Cleaner such as BioGuard Filter Renew, FreshWater Instant Filter Cleaner or Crystal Water Filter Cleaner at least once a fortnight. This breaks down stubborn oils, lotions, and grime that a basic rinse can’t remove. Simply spray the cleaner generously over the filter, let it soak for 10–15 minutes, and then rinse thoroughly.

👉 Pro tip: Regular cleaning keeps your spa filter free-flowing, reduces strain on your pump, and ensures your water stays sparkling.

2. Replace Your Spa Filter Every 12 Months

Even with regular cleaning, spa filters wear out over time. We strongly recommend replacing your spa filter every 12 months to maintain optimal performance. An old or clogged filter loses its effectiveness, allowing dirt and particles to slip through, which can quickly turn your water cloudy and unhygienic.

3. Signs Your Spa Filter Isn’t Working

Wondering if your spa filter is underperforming? Watch for these warning signs:

• Your spa water remains cloudy, even after adding chemicals.

• The jets feel weaker than usual, indicating restricted water flow.

• You notice dirt, debris, or oily residue floating on the water’s surface.

• The spa filter itself appears damaged, discoloured, or misshapen.

If you experience any of these issues, it’s a clear sign your spa filter needs a deep clean—or, if it’s over a year old, a full replacement.

4. Why Spa Filter Maintenance Matters

Neglecting your spa filter can cause a variety of problems, including:

• Cloudy water: A clogged or dirty spa filter struggles to keep your water clear.

• Increased chemical use: Inefficient filtration means you'll need more sanitiser to maintain water balance.

• Spa equipment strain: A blocked spa filter forces your pump and heater to work harder, risking costly repairs.

• Bacteria build-up: A poorly maintained spa filter allows harmful bacteria to thrive, affecting both water quality and your health.

Conclusion

Keeping your spa filter in excellent condition is a simple step that makes a huge difference. By rinsing and applying Filter Cleaner every fortnight—and replacing your spa filter annually—you’ll extend the life of your spa, reduce maintenance costs, and enjoy consistently clean, safe water.
