Can You Backwash a Cartridge Pool Filter?

Finding the best way to keep your pool clean is one of the most important things any pool owner should consider. One of the most effective ways of maintaining a clean pool is by using a pool filter. While there are different types of filters available, cartridge pool filters offer a unique combination of affordability, low-maintenance, and superior filtration.

However, like any other filtration system, a cartridge pool filter has a limit to how much dirt and debris it can hold before it clogs. Though most people think that cleaning a cartridge pool filter involves removing and replacing the filter cartridge, backwashing is an effective technique that can help increase the lifespan of your cartridge filter. In this article, we’ll discuss if you can backwash a cartridge pool filter.

What Is a Cartridge Pool Filter?

Before we delve into the details of backwashing a cartridge pool filter, let’s first define what it is. A cartridge pool filter is a form of a pool filter that operates by trapping and filtering tiny particles in the pool water through a porous cartridge. This cartridge is made from pleated polyester fabric and can trap dirt that measures as small as 5 microns.
