Benefits of Owning A Cartridge Filter

If you own a residential swimming pool there are three different types of filters for your swimming pool. The most common is the sand filter but cartridge filters are also becoming more popular with DE filters not being as common. 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. For most residential swimming pools, four filters are the most common. 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. The reason they are becoming more popular is they require the least amount of maintenance, conserve water due to no backwashing, and they keep the pool extremely clean.

As a Las Vegas swimming pool service and maintenance company, we are the biggest fans of the cartridge filters. Since water conservation is important in our area and since you don’t need to backwash, 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 psi or more depending on what the owner’s manual states), and the filters should be cleaned. Please don’t always depend on the gauge because they can be unreliable and that is why we highly recommend cleaning the filters every six months.

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. After that, we recommend soaking them in detergent or chlorine overnight. As soon as they are cleaned they can be put back in the filter housing for immediate use. Depending on the size of your pool, the 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. The following are the pros and cons of owning a cartridge filter:


  • Simple to maintain
  • Filters down to 10 microns
  • Best for water conservation due to no backwashing
  • Filters better in large surface area pools


  • More expensive filter
  • Cartridge replacement can be more expensive

In the end, cartridge filters are a great choice if you’re looking to keep your swimming pool clean and are relatively easy to maintain.
