How to replace a Frigidaire refrigerator water filter (all PureSource series)

Frigidaire refrigerator filter replacement: quick, tool-free, and straightforward

All Frigidaire PureSource filters are designed for tool-free replacement and take under five minutes. This guide covers ULTRAWF, WF3CB, and WF2CB — the three most common Frigidaire water filters.

Identify your filter first

• ULTRAWF — most Frigidaire and Gallery models from 2010+
• WF3CB — Frigidaire side-by-side models 2006–2012
• WF2CB — older Frigidaire models, FC-100 housing
• FPPWFU01 (PurePour WF-1) — select newer Frigidaire models

Replacing the ULTRAWF (upper interior filter)

1. Open the fridge and locate the filter in the upper-right interior compartment.
2. Turn the old filter counterclockwise about a quarter turn.
3. Pull the filter straight out. Have a small towel handy — a few drops of water may fall.
4. Insert the new ULTRAWF into the housing, aligning the tabs.
5. Turn clockwise until it locks. The filter should sit flush with the compartment cover.
6. Flush 2 liters of water through the dispenser before use.
7. Reset the filter light — hold the “Filter Reset” button for 3 seconds on the control panel.

Replacing the WF3CB

1. Locate the filter in the upper interior of the fridge.
2. Push the filter release button and pull the filter straight out.
3. Insert the new WF3CB — push until it clicks.
4. Flush 2 liters and reset the indicator.

Replacing the WF2CB

1. The WF2CB sits in the FC-100 filter housing, typically inside the fridge or in a lower compartment.
2. Turn counterclockwise to unlock and remove.
3. Install the new filter by aligning and turning clockwise until seated.
4. Flush 3 liters — the WF2CB has a large carbon block that requires a longer flush.

Frigidaire air filters: a quick note

If your Frigidaire also has an air filter (a common add-on for odor control), those need replacing every 6 months too. Check out our FRGPAAF1 PureAir air filter and FRPFUAF1 PureFresh universal air filter.
