This is the larger of 2 cartridges required for the S7M120.
The inner 100 sq ft cartridge is sold separately.
I need to replace this cartridge.
I thought the part numbers on top of my existing installed cartridge was 25022-0221.
It is 16.5 inches wide.
Is the S7M120 200 Sq Ft the same cartridge?
Thanks again,
Brian

Hello Brian, The 25022-0221 has been replaced by the 250220201S and is the correct filter for the S7M120. The part number for the smaller one has also changed from 25021-0220 to 250210200S.

I need filters for my Sta-Rite pool pump. 'outer filter' is pn 25022-0221 - tall inner filter has part number wore off - I think it is 25021-0220 - I need both filters. Tall filter is 27" ht. (28 1/2 including feet) with 4" ID and 8 1/2" OD. Thank you!

HI Joan, The S7M120 200 Sq Ft. Outer Replacement Cartridge (250220201S) and the S7M120 100 Sq Ft. Inner Replacement Cartridge would be the correct filters that you will need.

I am looking to replace both filters in my Sta-Rite pool pump. Your recent answers have answered the question for the large filter but for the small inner filter, I am looking for the one with 20 micron and 100 sq. feet. Can I simply go with the #2502-10200s that you mentioned in a previous discussion? Thank you

Hi Steve, The 100 SQFT Small Cartridge (25021-0200S) will be the correct inner cartridge that is used with this Outer Cartridge for the System 3 S7M120 unit.

My STA Rite S7M120 filter calls for the cartridges - 25021-0200S and 25022-0201S which total 300 SQ FT.
Is it true that the higher cartridges totaling 400 SQ FT would also fit my filter and actually clean the pool better - 25021-0223 and the 25022-0224?
It looks like they are virtually the same size within a 1/4".
Please let me know as soon as you can.
Thank You

(5 out of 5 stars) great filter cartridge
Reviewed By: swimming fool from Kilgore, TX ()
Had a terrible summer last year w/ much effort to get rid of algae. Thought it was mostly due to very hot weather all year. Finally determined cartridges were too old & ordered from replacements from INYO. Received them more quickly than expected and shipping charges were very reasonable. Pool water began clearing up right away. Will definietly order again from INYO.

Pros: Best price for original equipment replacement!
I carefully shopped all of my local suppliers and six internet suppliers for the lowest, delivered price on this System 3 cartridge filter. Inyo blew away the competition, and the filter was delivered as promised.
