Pool Filter Size Calculator 🧊

Determine the required filter surface area for your pool. Ensure your sand, DE, or cartridge filter matches your pump's flow capacity. A properly sized filter reduces maintenance frequency and ensures your water remains sparkling clear throughout the season.

FAQ

Is a bigger pool filter better?

Yes. A larger filter has more surface area, which means it can go longer between cleanings and provides less resistance to the pump, improving overall system efficiency.

What are the three main types of pool filters?

The three types are Sand (easiest to use), Cartridge (no backwashing needed), and D.E. (Diatomaceous Earth - provides the finest level of filtration).

How do I calculate the required flow rate for my filter?

Take your total pool volume and divide it by the desired turnover time (usually 8 hours) to find the minimum GPM (Gallons Per Minute) your filter must handle.
