Product details

The Unicel C-7489 is a 112 square foot replacement pool filter cartridge. Unicel lists it as the replacement for the Hayward cartridge CX875RE, and the element is listed under Hayward as the filter manufacturer.

Why area matters

Filter area is dirt holding capacity. A 112 square foot element gives the pleats room to load before pressure rises, which is what determines how long you run between cleans. Fitting a smaller element in the same tank does not save money, it just means cleaning more often and running the pump against higher pressure in between.

Check the dimensions before ordering

The manufacturer data for this cartridge carries two dimension readings. The attribute list gives a 7 in. outside diameter with a 25-1/2 in. length, while the product description gives 25-3/8 in. by 6-7/8 in. by 3 in. Measure your existing element, or go by the Hayward number CX875RE, rather than ordering on the dimensions alone.

Questions and answers

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

What Hayward part does this replace?
CX875RE.
How much filter area does it have?
112 square feet.
What are the dimensions?
The manufacturer data carries two readings. The attribute list gives a 7 in. outside diameter and a 25-1/2 in. length, and the product description gives 25-3/8 in. by 6-7/8 in. by 3 in. Measure your old cartridge and compare before ordering.
When should a cartridge be replaced rather than cleaned?
When the pleats have gone soft or splayed, when the fabric is thin or torn, or when pressure climbs back up within days of a clean. At that point the element is passing dirt no matter how well you wash it.
