The short version

A cartridge filter traps finer particles and wastes no water because it is rinsed rather than backwashed, but the cartridges need cleaning and eventual replacement. Sand is cheap, forgiving and backwashes in minutes, at the cost of coarser filtration and hundreds of gallons of water each time. Use cartridge where water is expensive or you want clearer water; use sand for low-maintenance simplicity.

You want clearer water or you live somewhere water is metered, scarce or restricted. Cartridge filters trap finer material than sand and lose nothing down the drain, which matters both environmentally and on the bill.

Choose the 13 in Sand Filter Pump System, 1 HP if…

You want the least involved maintenance routine. Backwashing is a lever pull rather than a job, and sand is very tolerant of neglect. It is the reason so many pools still run sand decades after cartridges appeared.

Frequently Asked Questions

How often should I clean a cartridge?

When pressure rises roughly 8 to 10 psi above the clean baseline, which is typically every few weeks in season. Note the clean pressure when the cartridge is new, since that reading is what everything else is measured against.

Can I use glass media instead of sand?

Yes, in most sand filters, and it generally filters finer and lasts longer. It costs more upfront and is a straightforward upgrade at the next media change.

Does a bigger filter help?

Generally yes. An oversized filter runs longer between cleans and creates less back pressure, and it is one of the few pool components where going up a size is usually a good decision.
