5 Reasons Sand Filters Are Best for Most Residential Pools
Simpler maintenance Sand filters clean by trapping dirt in a sand bed. When dirty, you backwash for five minutes with no replacement parts needed.
Lower ongoing cost Cartridge filters require pulling and hosing down the cartridge every four to six weeks, plus periodic replacements. Sand filters have no such recurring expense.
Good enough filtration for most pools Sand filters catch particles down to 20–40 microns. For typical backyard pools, that difference from cartridge filters (10–15 microns) is unnoticeable.
Set-and-forget operation Once installed, a sand filter needs little attention beyond occasional backwashing. Cartridge filters demand regular hands-on cleaning.
Fine debris is the only exception If your pool gets heavy pollen, dead algae, or tiny flower debris, a cartridge filter may prevent cloudy water. Otherwise, sand is the smarter choice.
