The Filter fingers prevent the filter sand from entering the pool. The filter fingers can crack over time and need to be replaced as necessary. 

The filter finger in a pool filter are small tubes or pipes that are located inside the pool sand filter. They are responsible for distributing the water that flows through the filter evenly across the entire surface area of the filter media. This helps to ensure that the water is filtered effectively and efficiently as all of the contaminants are exposed to the filter media. The filter finger also help to create a uniform flow of water through the filter which helps to prevent clogs and other issues that could disrupt the filtering process.

Suitable for all Eartheco filters.
