Polyester filter balls are a type of filter media that can be used in sand filters for swimming pools and other water filtration systems.
These filter balls are made from polyester fibers that are designed to trap and filter out impurities such as dirt, debris, and other contaminants from the water as it passes through the filter.

Compared to traditional sand or DE (diatomaceous earth) media, polyester filter balls are lightweight, durable, and easy to clean. They can be reused multiple times and require less backwashing, which can help save water and energy.
Additionally, polyester filter balls can improve filtration efficiency and water clarity compared to other filter media.
Overall, polyester filter balls are a popular alternative to traditional filter media in sand filters, offering improved performance and cost savings over time.
