Description
The fine Balls polysphere filter medium is an alternative to sand thanks to its longer operating life.
Eco Friendly, Reusable 
The filter polyspheres are made of 100 % PET with a grain size of 5 cm and can be used to clean your pool water more quickly and efficiently, thus your pool filter will consume less energy. The polyspheres are easy to wash by hand. Delivery includes one pack containing 500 g fibre spheres.
balls
Characteristics: Filter balls made of polyethylene fiber catch even fine dirt very quickly and can replace or supplement the usual sand filtration of swimming pools. Use: Balls can be used as a substitute for filter sand and poured into the filter container according to the recommended volume. Basic maintenance/rinsing is the same as for sand. After a certain time (depending on the pollution), we recommend removing the balls and washing them by hand or in a washing machine at 30°C and reuse them. Balls can be used both as a substitute for filter sand, as well as to supplement it and strengthen its filtering capabilities. It is possible to add them to the sand filtration container or pour them into the skimmer. (Consequently check the flow rate and ensure that the balls are not sucked in by the pump!)

✅ Advantages of Filtration Balls over Sand
1. Better Filtration Performance
•Higher precision: Filtration balls can filter particles down to 1–5 microns, while sand typically filters down to about 20–40 microns.
•This results in clearer, cleaner water and better removal of fine debris and contaminants.
2. Lighter Weight
•Filtration balls are much lighter than sand (a few hundred grams vs. 25–50 kg of sand).
•Easier to handle during installation and maintenance.
•Reduces stress on filter housing and plumbing components.
3. Improved Flow Rate
•Because they’re less dense and more porous, filtration balls maintain a better water flow, improving the efficiency of the circulation system.
•Can lead to lower energy consumption since the pump doesn’t have to work as hard.
4. Less Backwashing Needed
•They don’t clog as easily, meaning less frequent backwashing, which saves water, time, and energy.
•Reduced water waste is particularly helpful in areas with water restrictions.
5. Longer Lifespan
•High-quality filtration balls can last several seasons if cleaned properly, potentially outlasting sand, which should be replaced every 3–5 years.
6. Eco-Friendly Options
•Some brands offer recyclable or reusable filtration balls, making them more environmentally friendly.
