We want to replace our filter cartridge. It says we have a Porpoise PA175. What is the correct replacement cartridge?

Hello Beth - The correct replacement cartridge for the Porpoise PA175 is the NFC1294.

Is this filter a hayward filter or another brand ????

A  Answered on 8/18/2015 by InyoPools Product Specialist Hector F.

This is a cartridge element that works in a Hayward model filter but is manufactured by Filbur as a generic version.

Hi: I noticed you have a procedure to calculate shipping charges to Puerto Rico. I am interested in this generic cartridge but do not want to go thru the process. Is it possible? I will be paying my purchase with a credit card or paypal which better fits. Thanks.

A  Answered on 8/20/2015 by InyoPools Product Specialist Bob D.

Hi Rodo. You can get to the point where you put it in your shopping cart and estimate he shipping cost then cancel if you like. It won't process until you complete "Checkout." I tried it on my account to ship to several different postal codes in Puerto Rico via UPS Ground (the cheapest) and got $88 for shipping. The size (28") of the cartridge is what drives the price up. A much heavier item but smaller will usually be much less expensive.

Filter needed replacement due to heavy contaminants.

Written on 12/24/2020 by Guest

Ordered new filter cartridge. Released pressure on the filter itself with small knob on top of filter. Rotated large handle until top half of filter released. Took top half of filter off and removed old filter. Opened bottom knob on filter allowing water and any debris to run out. Sprayed with hose to rinse thoroughly. Replaced knob after lubing gasket. Inserted new filter. Replaced top half of filter. Be sure to lube large gasket before tightening top half of filter. Turn on pump. Release pressure on filter as appropriate.

The product was delivered before its scheduled time (grateful for that). Also, free shipping (grateful for that also). My husband installed it after removing a deteriorated cartridge.
