Cartridge Pool Filter Replacements

Pool filter cartridges are generally replaced every 1 to 3 years, depending on pool usage, water quality, and how often the cartridge is cleaned. Pools that run throughout the year or experience heavy use may need a more frequent replacement.

To choose the correct pool filter cartridge, check the filter brand and model, as well as the cartridge’s length, diameter, and top and bottom end cap style. This information is commonly printed on the existing cartridge or listed on the filter housing.

The cost of a pool cartridge filter varies based on size, filtration surface area, and brand. Smaller or standard replacement cartridges are typically more affordable, while larger cartridges designed for higher flow systems may cost more.

On average, a pool filter cartridge lasts about two years. With proper cleaning and care, some cartridges may last longer, while others may need replacement sooner due to wear or water conditions.

The pool filter model number is usually located on a label attached to the filter tank, in the product manual, or sometimes stamped directly on the cartridge itself. However, it is not the recommended way to match as the same stamping may apply to multiple filter models.

Common signs that a pool filter cartridge needs replacement include persistent cloudy water, reduced water circulation, increased pressure readings, or visible damage such as torn pleats or cracked end caps.

Yes, pool filter cartridges can and must be cleaned regularly to remove dirt and debris instead of simply replacing them. Although cleaning helps in saving money and in extending filter life, it cannot restore a cartridge that is worn or damaged.

Most pool filter cartridges are designed to be cleaned and reused multiple times. Once the filter material begins to degrade or no longer improves water quality after cleaning, replacement is the best option for homeowners.
