Product details

The Hayward CX225RE is the genuine replacement cartridge element for the StarClear C225 cartridge filter, with 25 square feet of filter area.

Why the fit matters

A cartridge filter only works if the water is forced through the pleats. An element that does not seat properly in the housing leaves a path around the outside, and dirty water takes it. That is the practical argument for a factory element: it holds the dimensions the housing was built to, so the filter performs the way it did when it was new.

What Hayward claims for it

Hayward builds these cartridges to meet NSF performance and durability standards, and states they deliver strong first pass debris removal, longer filtration cycles and multi season life. In practice that translates to fewer cleanings across a season and an element that lasts past a single summer.

Cleaning and replacing

Rinse the pleats out rather than blasting them, since a pressure washer drives dirt into the fabric and opens the weave. Replace the cartridge when it stays gray after a proper cleaning, when the pleats tear or separate from the end caps, or when filter pressure climbs back to dirty within days of a wash.

Questions and answers

What people ask about this product, answered by our pool techs.

Which filter does this fit?
The Hayward StarClear C225. The listing also carries the StarClear Plus C225-Blue name, so both references point at the same 25 square foot element.
How big is it?
25 square feet of filter area, which is the rated area of the C225 housing.
Is a genuine cartridge worth the difference?
Hayward makes the case on fit. An element built for the housing seats where it should, so dirty water has to go through the pleats instead of slipping around them, and the filter keeps the performance the original had.
How often should I replace it?
A cartridge is cleaned repeatedly and replaced when the pleats stay gray after cleaning, when the fabric tears, or when the pressure comes back up too quickly after a wash.
