Product details

The Pentair 178655Z is a genuine replacement cartridge for the Quad D.E. 80 filter. It is supplied as a single cartridge and measures 26-3/4 in. tall by 6-1/4 in. wide.

Order the right quantity

This is one element, not a complete set. A Quad D.E. filter runs several cartridges together, and they load up at the same rate, so replacing them as a group is what actually brings the pressure back down. Count what is in your filter before you order.

A note on the rated area

Pentair source data is not consistent on this cartridge. The product name gives 80 sq ft, while the detail line gives 20 sq ft for the same cartridge in the same Quad D.E. 80 filter. The dimensions are consistent at 26-3/4 in. by 6-1/4 in., so measure the cartridge you are replacing and check the model plate on your filter before ordering.

When to change

Cartridges survive many cleanings, but the fabric eventually holds oils and fine debris that will not rinse out. If a thorough wash no longer drops the filter pressure to its clean starting point, or the fabric is torn or thin, it is time.

Questions and answers

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

Is this one cartridge or a full set?
One. Pentair 178655Z is a single replacement cartridge, so order the number your filter holds.
Is it 80 square feet or 20?
The source data carries both figures. The product name says 80 sq ft and the product detail says 20 sq ft for the same cartridge in the Quad D.E. 80 filter. Check the label on your filter and the cartridge you are pulling out before ordering.
What are the dimensions?
26-3/4 in. tall by 6-1/4 in. wide.
When should the cartridges be replaced?
When a proper wash no longer brings the filter pressure back to where it started, or when the fabric is torn, thin or permanently packed. Cleaning past that point only buys a few days.
