Which refrigerators does Filter 4 fit?

It is made for KitchenAid and Whirlpool refrigerators that use the Filter 4 cartridge. Check your fridge's model or current filter number before buying.

What part numbers does it replace?

It replaces W11256135 and W11311161. It is not a fit for fridges that take Filter 1, 2, 3 or 5.

How often should I change it?

Every six months or 200 gallons, whichever comes first. Hard water or heavy use may call for earlier changes.

Does it remove fluoride?

No. It is certified for lead, pesticides, pharmaceuticals and other contaminants, but not fluoride.

Is it better than a generic filter?

Generic filters are cheaper but usually lack the same NSF-certified contaminant list. This one carries the OEM certification for these fridges.

Why is my water flow slowing down?

Flow drops as the cartridge loads with contaminants. If it slows well before six months, your water quality or usage is likely the cause.
