About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

Pool filter balls 700g

Manufacturer’s product description

The Fox Bunny Pool Filter Balls (700 grams) are a modern alternative to conventional filter sand and are suitable for many common sand filter systems in pool applications. A particularly practical feature is that 700 grams of filter balls can replace up to 25 kilograms of filter sand, significantly reducing weight and making replacement much easier.

During testing, it was noted that the fine filter structure reliably removes even small dirt particles from the water, resulting in visibly clean pool water. The reusability of the filter balls is also impressive, as they can be washed and reused as needed, saving costs in the long run. Another advantage is their ease of use and high water permeability, which allows the filter system to operate efficiently.

A negative aspect noted during the test is that the backwash function may be limited if the dosage is incorrect or the system is overfilled.In cases of heavily contaminated water, more frequent cleaning may be necessary, which entails additional maintenance effort. Not every filtration system works optimally with the filter balls, so compatibility should be checked before use.

Overall, however, they are a lightweight and convenient alternative to heavy filter sand with impressive filtration performance.

  • Replaces 25 kilograms of filter sand
  • Very light and easy to handle
  • Washable and reusable
  • Cleaning is required
  • Not suitable for every filter system

The Fox Bunny Pool Filter Balls (700 grams ) impress right from the first touch with their soft yet dimensionally stable material structure, which is designed for reliable filtration performance. The visual appearance is clean and evenly finished, leaving a good first impression. The high-quality workmanship is also evident in the fact that no unpleasant plastic or chemical odor is detectable, which is particularly important for pool products. The stability of the individual balls was a positive feature, as they retain their shape even under light pressure and do not immediately fall apart, suggesting a longer service life. We also noted that the filter balls are very lightweight and can be easily added to the filter system without requiring any additional tools. Although no detailed information on sustainable materials is provided, the reusability of the filter balls makes them a sustainable solution. Overall, the filter balls appear to be well-engineered and designed for practical and long-lasting use.

In practical use, the Fox Bunny Pool Filter Balls (700 grams ) largely deliver what the manufacturer promises. The high filtration performance is particularly impressive, as the pool water becomes visibly clearer after a short period of operation and even fine dirt particles are reliably trapped.If the dosage is incorrect or the filter is overfilled, the backwash function may be impaired. Not every filter system works optimally with the filter balls, which is why compatibility should be checked before use. The small quantity of just 700 grams as a replacement for large amounts of filter sand significantly simplifies handling and makes filling the filter system much more convenient. Thanks to the lightweight material, installation is quick and can be done without much effort. Additionally, the good water permeability ensures that the filter system can operate efficiently and maintains a consistent water flow. The reusability of the filter balls is also practical, as they can be used again after cleaning, which saves costs in the long run.

Overall, the filter balls impress with their ease of use, reliable filtering performance, and noticeable reduction in labor compared to traditional filter sand.
