About This

• ✅ SIX CARTRIDGES, 5 MICRON: Six string wound sediment cartridges at 5 micron in the standard 10 x 2.5 inch slim line size. At a three to six month change that is eighteen months to three years on a single housing.
• ✅ WOUND TIGHTER AT THE CORE THAN AT THE SURFACE: Polypropylene cord is wrapped over a central core in a graded pattern, open on the outside and dense toward the middle, so coarse grit is held near the surface and finer particles are retained deeper in. Water passes through the full thickness of the winding rather than stopping at one face, which is what gives a wound cartridge its dirt holding capacity on well water where the sediment is never one uniform size.
• ✅ 5 MICRON, 9.75 x 2.5 INCH SLIM LINE: A mid-range grade - fine enough to catch the sand, silt, dirt, rust and scale that cloud water and wear on fixtures and appliances, coarse enough not to load quickly on a dirty supply. Cartridges in this same body are made from 1 to 50 micron and look identical once out of the wrapper, so match the number printed on the one you are pulling out rather than going by the housing model.
• ✅ FITS THESE PART NUMBERS: Direct 5 micron replacement for WHKF-WHSW, WHCF-WHSW, WP5, WP-5, W5W, W5P, CW-5, CW-F, FXWSC, SWC-25-1005, SWF-25-1005, SDC-25-1005, RS2-DS, RS5-DS, RS2SS, SP-CW5, SF5-978, 38478, 4238478, 84621, 155071-43, 155877-43 and 155186-52. Seats in WHKF-DWHV, WHKF-DWH, GXWH04F, GXWH20S, GXWH20T, HF-150A, HF-360A, AP11T, W34-PR and the HF2, HF3 and HF4 housings. CFS is an independent brand - a compatible replacement, not an original manufacturer part.
• ✅ SEDIMENT ONLY - WHAT IT DOES NOT DO: This is a particle filter and that is the whole of it. There is no carbon in a string wound cartridge, so if your water needs a carbon stage, run one downstream of this rather than instead of it - putting sediment first is what makes that carbon last. Replace every 3 to 6 months, or sooner when the pressure at your taps starts dropping.
