Compatible with AO Smith AO-WH-PRE-RP2 and other standard 10" x 2.5" housings, this 4-pack ensures up to 18 months of reliable filtration with reusable pleats, delivering exceptional value and performance for whole-house sediment removal. ## Description CFS pleated sediment cartridges in the standard 10 by 2.5 inch slim line size, 20 micron, four per pack, replacing S1, S1A, S1A-D and 155001-43. At a change every three to six months, four cartridges cover a year to eighteen months on a single housing, and longer again if you rinse them between changes. Pleated media keeps indefinitely on the shelf, so buying the interval at once costs nothing but space. Pleated construction is the reason these outlast a spun cartridge of the same size. The polyester media is folded into an accordion rather than wound smooth, which packs far more surface area into the same body. Sediment spreads across the whole pleated face instead of loading one spot, so you get high flow, less pressure drop, and considerably more dirt held before the cartridge is finished. It also means you can rinse it: take it out, hose the pleats down, refit it, and it will run again. It replaces S1, S1A, S1A-D, 155001-43, ECP20-10, W20CLA, SPC-25-1020, AO-WH-PRE-RP2 and PE-F10-20, which are the same 20 micron pleated cartridge sold under different part numbers. Watch the grade rather than just the size: 5 micron versions of this identical body exist and fit the same housings, and they are not interchangeable, so match the number printed on the cartridge you are pulling out. On the housing side it fits GXWH20T, GXWH04F, GXWH20S, WFPF13003B, WFPF38001C, HF-150A, HF-160, HF-360A, HF-365, WH-S200-C, AP11T, AP101T, AO-WH-PRE, AO-WH-PREV, WHKF-DWHV, WHKF-DWH, W34-PR, WC34-PR, WVC34, PS-WHS-H, PS-WHS-HV and the HF2, HF3 and HF4 series, along with most other housings that take a 10 by 2.5 inch cartridge. Measure before ordering. This is the slim 10 by 2.5 inch cartridge, not the 4.5 inch big blue and not a 20 inch length; they look similar in a photograph and are not interchangeable. This is sediment media. It captures particles and that is all it does. It is not carbon and does not alter the taste or odor of your water, so if chlorine taste is why you are filtering, run a carbon cartridge after this one rather than instead of it. Compatible replacements made by CFS, not original manufacturer parts. ## Features - WASHABLE PLEATED DESIGN – Accordion-fold polyester pleats give far more surface area than spun cartridges: high flow, less pressure drop, and you can rinse the pleats clean between changes to extend service life. Compatible replacement for 20 micron AO-WH-PRE-RP2 pleated cartridges (CFS brand, not an OEM AO Smith product); same standard size and grade as FM-50-975, S1, S1A, ECP20-10, W20CLA and other 10" x 2.5" pleated cartridges. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B093CJZZLG | | Best Sellers Rank | #308,134 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,952 in Replacement Under-Sink Water Filters | | Brand | CFS | | Brand Name | CFS | | Compatible Water Purifier Models | A.O.

With the initial strainer the 20 micron and the carbon are changed quarterly. **Q: What is the nominal GPM rating for these 20 micron filters?** A: They work well with well pumps. Would not recommend on a high pressure water system. ## Frequently Bought Together - CFS – 4 Pack Pleated Polyester Sediment Water Filters Compatible with W50PE, WFPFC3002, SPC-25-1050, FM-50-975 Models – Whole House Replacement Water Filter Cartridge – 20 Micron - Aquaboon 5 Micron 10x2.5 Whole House Pleated Sediment Filter Cartridge for Well Water Filter Replacement Compatible with WFPFC3002, WHKF-WHPL, 4-Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/318249696-cfs-pleated-water-filters-compatible-with-ao-smith-ao-wh](https://www.desertcart.co.za/products/318249696-cfs-pleated-water-filters-compatible-with-ao-smith-ao-wh) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-27*
