Quick Overview of Pool Filter Cartridges

by Pool Builders on 11-02-2010 in Articles

If you are the proud owner of a new backyard swimming pool and need to decide what type of filter will best meet your needs, you have three basic choices: Sand, DE and pool filter cartridges. Here is a quick overview of the latter type, some of its advantages, and how to know if it's the right type for your needs.

Pool filter cartridges are perfect for home spa use and they also work well for small backyard pools with a capacity of 30,000 gallons or less. The filter element is composed of rolled corrugated paper or polyester cloth that traps particles between 25 and 100 microns in size. This type of filtering system is adequate for most backyard pools that get moderate use during the season.

One of the main advantages of cartridges is that they are extremely low maintenance. When the pressure gauge rises 10 pounds over the "clean" level, you simply remove the cartridge and clean it using a high-pressure hose. Most pool owners only have to do this once or twice during the season thanks to today's much-improved cartridge designs. It should be replaced every two years or so unless it gets a lot of wear and tear: in this case, it should be replaced yearly.

Another advantage of pool filter cartridges is their low cost. A new one from a brick and mortar retailer should cost 100 dollars or less; if you purchase one from an online discounter, you can get one for up to half that amount. You can install it and maintain it yourself without the need for professional help, making a cartridge the all-purpose work horse for most backyard pools.
