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 filter!

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.

?     Asked on 7/16/2016 by Tomas

Had a new filter cartridge and used it about 2 weeks. The pressure gauge started at about 12 when first installed, when it got to about 22 I cleaned the cartridge because I noticed my waterfall was coming out weak. After that first cleaning, now the pressure goes to around 23 almost immediately after it is cleaned and the waterfall is weak. The cartridge is not dirty, it looks brand new, but repeated the process several times with the same result. Any idea why this is happening?

Hi Tomas, You may have to soak the cartridge in a Filter Cleaner solution to remove any build up oils that could be in the filter.

I am looking for a filter for a Hayward micro star cleaner model #SP1540CLSNP. I can't find the model # on the filter itself. It is for a pool filter system. Thank you for your time.

The model number you provided matches a Hayward PowerFlo LX pump. The model number does not reference a filter. In order to assist you better, I would need the model of the filter, or you can view the Hayward Micro Star Clear Parts diagram to determine which filter would fit your filter.

 (5 out of 5 stars)  Why pay more?

from Livermore, CA ()

Pros: Perfect fit, less expensive

Cons: none

Maintenance of a pool is expensive. Filters although they last a long time need to be replaced from time to time. We decided to try a "generic" alternative and feel very lucky to have that choice in these filters. We put them in our Hayward system and they fit like a glove.

 (5 out of 5 stars)  Great filter, great price!

from Bluffton, SC ()

Pros: works perfectly

Cons: none

We have purchased these filters from a local pool store for a few years. After buying some other products at great prices here, we found that we could get them from Inyo at a much, much better price. Will come back for all our future products!

 (5 out of 5 stars)  I use them for my Koi pond and they work great

from Abilene, TX ()

Pros: Keeps the water crystal clear,

Cons: I have to wash the filter at least every other day

I use these filters for my Koi pond and they work great. In the past I have tried a lot of products but none of them work as well to keep the pond crystal clear. The moey I save on the other products more than pays for the filters.
