If you’ve been following along with our blog we recently had a discussion about the different types of filters and which one would work great for your swimming pool. As many of you know there are three different types of filters; sand, diatomaceous earth and cartridge. Each of them are extremely efficient for swimming pools but in this blog post we want to highlight and discuss cartridge filters! Cartridge filters are typically tall and slender in shape. Inside the filter you will find anywhere from one filter to several depending on the size needed for your swimming pool. Each filter looks like a tube and pool water flows from the outside of these tubes, through micro-sized pores and then that water is returned back to the pool! Cartridge filters are the best choice for both first-time pool owners and experienced veterans. They require pretty much low maintenance and oversight, while keeping your pool extremely clean!


Dirty cartridge filters

As a Las Vegas swimming pool service and maintenance company we like all filters for swimming pools but since water conservation is becoming a bigger issue, cartridge filters are always a great option because since they don’t require backwashing, you can save on average 200 gallons a month or more. However, when the filters are dirty you will notice that the pressure gauge rises (up to about 10 pounds or more depending on what they owner’s manual states) and the filters should be cleaned.

How To Clean A Cartridge Filter

When it’s time to clean your cartridges, the filter housing must be disassembled, and each cartridge must be hosed down to remove all dirt and debris. As soon as they are cleaned they can be put back in the filter housing for immediate use. Depending on size of your pool, amount of debris and run time will determine how long you can go before cleaning the filters. If your swimming pool is loaded with a lot of dirt, debris or if it ever turns green you will notice that the filters need to be cleaned more often. Again, always keep on eye on the pressure gauge.

Cartridge Filter Pros and Cons


  • Simple to maintain
  • Filters down to 10 microns
  • Best for water conservation due to no backwashing
