Keeping your pool water crystal clear is essential for safety, comfort, and overall enjoyment. But with so many filter media options available in Cape Town—from traditional sand to cutting-edge technology—many pool owners are asking: What are pool filter balls, and do they actually work? In this guide, we explore how pool filter balls compare to traditional sand, their pros and cons, and when they’re ideal for your pool filtration system.
What Are Pool Filter Balls?
Pool filter balls are a modern alternative to traditional sand used in swimming pool filtration systems. Made from polyester, polypropylene, or polyethylene fibres, these lightweight balls trap dirt and debris as water passes through your pool filter.
They’re compatible with most sand filter systems and are often marketed as a cost-saving, energy-efficient upgrade.

How Do Pool Filter Balls Work?
Pool filter balls function similarly to sand but with enhanced filtration power. Instead of relying on the weight and density of sand, these soft, fibrous balls provide a greater surface area for trapping particles as small as 3 microns. That’s finer filtration compared to sand, which usually captures particles between 20 and 40 microns.
Cape Town Tip: Due to fluctuating wind and dust conditions in areas like Brackenfell and Durbanville, filter balls may offer superior results in keeping pool water cleaner for longer.
Pros of Pool Filter Balls
Improved Filtration Efficiency
Filter balls capture finer particles, resulting in sparkling pool water clarity.
Lightweight & Easy to Handle
A single bag of filter balls can replace 25–30 kg of pool sand, making installation and replacement easy.
Energy Efficient
Because they create less resistance in the filter, they may reduce pump strain and energy consumption.
Reusable & Washable
You can rinse and reuse them, potentially extending their lifespan up to 3–5 years.

Cons of Pool Filter Balls
Initial Cost
Filter balls can be more expensive than sand at first, typically ranging from R700 to R1,200 per set.
Not Suitable for All Filters
While they’re compatible with many standard sand filters, they may not work with older or pressure-specific systems.
Requires Gentle Maintenance
Improper backwashing or pump speed may compress or damage the balls, reducing efficiency.
