Which cartridge filter do I need for my pool?
Why Is Proper Filter Sizing Important?
A filter that’s too small can lead to high pressure, restricted water flow, and quick clogging, which increases cleaning frequency and reduces system efficiency. On the other hand, a properly sized filter offers optimal filtration, requires less maintenance, and extends the lifespan of your pump and other components.
