CFS 5 Micron 10x2.5 Spun Sediment Filter for 155014-43 P5-4 Pack

• GRADED DENSITY DEPTH MEDIA - Melt blown polypropylene is spun loose on the outside and denser toward the core, so coarse grit is held near the surface and finer particles are retained deeper in the wall. The load spreads through the full thickness instead of blinding off one face, which is what keeps flow steady as it fills. 5 micron nominal.
• FOUR CARTRIDGES PER PACK - At a change every three to six months, four cartridges cover a year and a half to two years. Buying the interval at once costs less per cartridge than replacing one at a time, and it means the spare is on the shelf before pressure starts dropping at the taps.
• FITS THESE PART NUMBERS - Direct replacement for 155014-43 and 155014-52, and the same standard size as P5, P5A, P5-10, W5P, WPD-110, SDC-25-1005, WFPFC5002, AP110 and FP15. The actual length is 9-3/4 in, the standard nominal 10 in slim line size, so it seats in most whole house, under sink and countertop housings.
• SEDIMENT MEDIA, NOT CARBON - Spun polypropylene is a sediment cartridge. It captures sand, silt, dirt, rust and scale particles. It is not carbon and does not change the taste or odor of your water. If chlorine taste is why you are filtering, run a carbon cartridge after this one rather than instead of it.
• CLEARER WATER FROM EVERY SOURCE - Whether your home runs on municipal tap water or a private well, the cartridge captures the sand, silt, dirt and rust that cloud water and wear out fixtures and appliances. Replace every three to six months; falling pressure at the taps is the signal rather than a date. Compatible replacement made by CFS, not an original manufacturer part.

CFS melt blown polypropylene sediment cartridges in the standard 10 by 2.5 in slim line size, 5 micron nominal, four per pack, a direct replacement for 155014-43 and 155014-52. The media is spun in a graded density pattern: loose on the outside, progressively denser toward the core. Coarse grit is caught near the surface where there is room for it, and finer particles are retained deeper in the wall, so the load spreads through the full thickness of the cartridge rather than blinding off a single face. That is why a depth cartridge holds flow steady for longer than a surface filter of the same rating, and why it suits well water or any supply where the sediment is not one uniform size. Four cartridges covers a year and a half to two years at a change every three to six months, and buying the interval at once costs less per cartridge than replacing them one at a time. The actual length is 9-3/4 in, which is the standard nominal 10 in size, and the diameter is 2.5 in. It is the same size as P5, P5A, P5-10, W5P, WPD-110, SDC-25-1005, WFPFC5002, AP110 and FP15, so it fits most whole house, under sink and countertop housings whether or not your model is named here. If your housing came from an older manufacturer whose cartridges are no longer made, measure the one you are pulling out; if it is 9-3/4 by 2.5 in, this is the modern equivalent. It is sediment media, not carbon: it captures sand, silt, dirt, rust and scale particles and does not alter the taste or odor of your water, so pair it with a carbon stage if chlorine taste is the reason you are filtering. Running sediment first is also what keeps that carbon working longer, since the coarse material never reaches it. Replace every three to six months depending on your supply and usage, taking falling pressure at the taps as the signal rather than a date on the calendar. This is a compatible replacement made by CFS, not an original manufacturer part, and part numbers are used for reference only.
