There are three types of filters for backyard pools: cartridge, sand, and diatomaceous earth (often referred to as 'DE' filters). Their purpose is to remove dirt from the water, helping to keep it clear. And whatever type you have, keeping it clean is essential.
This aspect of pool maintenance is similar to changing the oil in a car, says Michael Shelton, the Co-owner of Pool Sharp. 'Cleaning your pool filter is important to make sure everything continues to run properly,' he explains. Over time, a dirty filter can damage other aspects of your backyard pool's plumbing, including the pump. And, it can turn the water cloudy.
