Product Description


  • Our generic replacement cartridges are less expensive than the original manufacturers' brands yet still meet the same high quality standards.  The key components of a cartridge - filter media, core, and end cap - are all designed for maximum water flow and cartridge life.
  • The filter media is point bonded polyester with even fiber distribution which results in an even dirt load and increased water flow.  
  • The Sharp & Uniform pleated media provides filtration area (square footage) that meets or exceeds the original manufacturers' specifications.  
  • An open core design provides sturdy support for the media without restricting flow.  Increased flow rates result in less wear on the pump and reduced energy usage.  
  • Anti-microbial end caps inhibit the growth of bacteria, mold and mildew while supporting the core and media.
  • Banded Pleats maximize flow during operation, and help to reduce the frequency of cleaning.  Banded pleats also make the cartridge easier to clean.
  • We carry thousands of generic cartridges to replace all of the most popular OEM brands such as Sta-Rite, Pentair / Pac Fab, Hayward, Purex, American Products, Jacuzzi,  Hot Springs, Coleman, and more.

You Should Consider the Microban version of this Cartridge!

Why Microban Protection?

Water and an ample food source provide the ideal condition for bacteria to quickly multiply and grow. In fact, on an unprotected surface, some microbes can double in number every 20 minutes. And only when they’ve multiplied to hundreds of thousands, can they actually be seen by the naked eye.

The images below show bacteria growth on a standard pool filter cartridge versus a pool filter cartrdge infused with Microban® antimicrobial protection over a 24 hour period.

Microban Pool Filter Cartridge

After viewing these images, you can see how Microban® protection begins to work immediately, disrupting key bacterial cell functions so that bacteria are unable to grow or reproduce on the surface. While on the unprotected surface, bacteria quickly multiply.

The Microban Version of this cartridge can be seen here.

What is the model number of your Hayward filter? I do not show a Hayward cartridge that matches those specs.

Our Hayward filter has the number C1750E, this is the 1st time trying to find a filter replacement the pool is a year old. Would the PA175 filter work?

Hi Charlene, This generic replacement cartridge will fit into the Hayward C1750 unit.

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 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.

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

A     Answered on 8/18/2015 by Hector F.

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

Pros: Price

Cons: Lasted less than a year.

I bought this filter to replace a Hayward original filter. The price of the stock Hayward filter was incredibly much too high at the local pool store. I was unable to find a reasonably priced Hayward filter online either. At a lower price I thought I would give this filter a try. The build quality appeared to be adequate. I placed the filter in and experienced excellent results. If you want a quality filter that costs about half as much as the stock filter and gives excellent results this is the filter. However, it lasted about 11 month.

I had problems with filters purchased at local pool stores. I have a lot of trees close by, leaves and debris are a problem. I also suspected a blow by with the other filters. The Hayward has a better fit.
