How long will my cartridges last?

Each pool and pool system is different, however there are a few recommendations that can help extend the life of your cartridges. First, we recommend that you have a second set on hand for opening the pool. This will help extend the life of the one set because it will not have the demand of filtering winter water.
Second, we recommend proper maintenance of the cartridges. This includes cleaning the cartridges throughout the season as necessary, as well as properly cleaning and soaking your cartridges before storing at the end of the season.
