Pool-filter cartridges are used to keep home swimming pools and spas clean. They can be used for pools with a capacity of 30,000 gallons or less volume of water. The filter cartridge is generally made of polyester cloth or corrugated paper that acts as a filter. When the filter is dirty and clogged, the water in the entire pool can become dirty. Check out these guidelines below to know how often you should replace your pool filter to keep your water safe and clean.
