Replacement MWF Filter Cartridge

The Waterdrop WD-F13 is a carbon-block refrigerator filter rated for 300 gallons or 6 months of service. It replaces GE MWF, MWFP, MWFA, GWF and Kenmore 9991 cartridges across a long list of compatible fridge models. The white plastic housing meets NSF/ANSI 42 and 372 standards with certificates issued in 2022. Maximum operating pressure is 100 psi and water temperature must not exceed 38 °C.

Suits GE and Kenmore owners needing certified

Households that want verified lead-free material compliance under NSF 372 will find the documentation supplied. Buyers whose refrigerator uses a different filter form factor or who require a higher flow rate than 0.5 GPM should look at something else. The cartridge is sold as a single pack, so homes needing multiple spares must order additional units separately.

Twist-in installation with no tools required

Align the cartridge, push upward and turn a quarter-turn until it locks; then flush 1 to 2 gallons to clear carbon fines. The most common issue is forgetting to purge air, which causes sputtering or cloudy water for the first few dispenses. O-ring seating should be checked if drips appear at the housing after the first day. No plumbing modifications are needed.

Questions about this item

Does the filter come with the housing or do I need to reuse the one already in my fridge?

This is a cartridge only; you reuse the existing housing in the refrigerator.

Will water pressure drop below the 0.5 GPM rating if my supply line runs at the 100 psi maximum?

The cartridge is rated for up to 100 psi and delivers 0.5 GPM under normal conditions.

How do I confirm the NSF 42 and NSF 372 certifications are valid for this cartridge?

Check NSF certificates C0293234 and C0145653 on the NSF International website.
