I have a Hayward filter which requires 4 filters. Filter casing says to use either CX875RE or CX1380RE and I don't know which to order. The Hayward filter says on the housing that it is serial # 2487 and 330D32.

Your best bet will be to measure your cartridges. The CX875RE measures 25-1/2" Long and the CX1380RE will measure 32-7/8" long. We do carry both of these cartridges on our website in both the OEM and a Generic and I have listed links to each of these products below: CX875RE OEM  http://www.inyopools.com/Products/07501352015358.htm  CX875RE Generic  http://www.inyopools.com/Products/00100000010677.htm CX1380RE OEM http://www.inyopools.com/Products/02200001004497.htm  CX1380RE Generic http://www.inyopools.com/Products/06400001004498.htm

Part PL0113. Does this part replace a 9 year old Hayward part noted as C-875

A  Answered on 7/1/2019 by InyoPools Product Specialist Patrick P.

Hi Bruce, Yes Part PL0113 does replace a 9-year-old Hayward part # C-875 This would be the correct replacement cartridge.

Will this replace my filters? Please see attached - It is a Hayward filter system


A  Answered on 11/5/2020 by InyoPools Product Specialist Hector F.

Hi Josh, could you send us a few photos of the entire filter label or the part numbers that should be molded onto the actual cartridge elements themselves? To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation.

is this item returnable if it is wrong

A  Answered on 5/15/2021 by InyoPools Product Specialist Patrick P.

Hi Barbara, Yes it is. Just make sure it is in unused condition and water has not passed over it. If it did not fit you would just be responsible for the return shipping.

Needed New Cartridge Filters

Written on 5/28/2020 by Guest

I removed the filter top, removed the top piece and removed the four filter cartridges. I installed the new cartridges, added the goop to the rubber O-ring and re-installed the top. Saved a ton of money getting the generic filters from INYO Pools!

Were these instructions helpful?
