A quality filter traps the dirt, oils and fine particles your pump pulls from the water — the foundation of crystal-clear pool water.
Clean, well-filtered water lets your UV system or chlorine work more efficiently, so you use fewer chemicals and spend less time balancing your pool.
Cartridge, sand and DE filters each offer simple upkeep. Clean or backwash when the pressure rises 8–10 PSI above its clean baseline.
A pool filter removes the suspended dirt and debris your pump pulls from the water, working hand in hand with your sanitizer to keep the pool clear. The three main types - cartridge, sand and diatomaceous earth (DE) - differ in how finely they filter and how you maintain them.
Cartridge filters offer fine filtration with simple rinse-clean maintenance, sand filters are low-cost and easy to backwash, and DE filters capture the finest particles for the clearest water. Size your filter to your pump's flow rate for the best performance.
It depends on the type and your pool's usage, but a good rule is to clean when the pressure gauge rises 8-10 PSI above its clean baseline. Cartridges are rinsed, sand and DE filters are backwashed.
Cartridge filters balance fine filtration with easy maintenance, sand filters are the most economical, and DE filters provide the clearest water. The best choice depends on your pool size and how hands-on you want to be.
Your filter should be matched to or larger than your pump's flow rate so water is filtered effectively without excess pressure. Contact us with your pump details and we'll help you size it.
