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. My site http://www.chinafiltercloth.com/

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.
