Pool filter cartridges such as the PLW50 need to be replaced over time. They become less effective in cleaning your poo water because they are worn, tattered or simply old thus not cleaning your pool water effectively. Replacing the cartridge inside your pool filter will insure you have clean water in which to swim. You also need to be sure to maintain proper balance of your pool water which will keep your pool water safe and clean.
