How to Replace Any Refrigerator Water Filter: Complete Cross-Brand Guide

Replacing a refrigerator water filter is straightforward: find the filter location, release the old cartridge (twist, push, or pull depending on brand), insert the new one, and run water to clear air pockets. The tricky part? Filters come in dozens of shapes and sizes, and compatibility isn’t just about brand—model year, housing design, and aftermarket quality all matter. This guide walks you through the process for major brands (GE, Samsung, Whirlpool, LG, Frigidaire, and Kenmore) and shows you how to avoid the most common headaches.

Before You Start: What You Actually Need

Gather these items before touching the fridge:

• New filter – Have the exact part number handy. Check the old filter’s label or your owner’s manual. Generic replacements work fine for most models, but double-check dimensions and connection style.
• Bucket or towels – Some water will spill when you remove the old filter.
• Screwdriver (optional) – A few models (older Kenmore, some built-in GE) use a housing cap that requires a flat-head screwdriver to unscrew.
• Gloves – Not required, but keeps hands dry.
• Manufacturer number – Write down the model/serial from inside the fridge door or behind the lower grille.

Which Filter Fits Your Fridge?

Not all filters are universal, but many brands share form factors. The table below covers the most common filter types and their typical fit:

Filter Type / Part Number	Common Brands	Typical Location	Notes
EveryDrop Filter 1 (EDR1RXD1)	Whirlpool, Maytag, KitchenAid, Amana, JennAir	Inside top-right corner of fresh food compartment	Push-in style; also fits some Kenmore models. Aftermarket options like HMASAV W10295370A are widely compatible.
GE MWF / GWF / RPWFE	GE, Hotpoint, some RCA	Grille at bottom front (MWF) or inside base grille (RPWFE)	Twist-and-lock bayonet. Newer GE models use RPWFE (taller). MWF is shorter.
Samsung DA29 / HAF-CIN / HAF-QIN	Samsung, some Kenmore	Inside upper-right compartment (DA29-00020B) or behind lower panel (HAF-QIN)	Push-in or twist.

DA29-00020B is common for French-door models. |

| LG LT1000P / LT800P / ADQ73214401 | LG, some Kenmore | Inside upper-right or behind lower grille | Push-in with a locking button. LT1000P is the standard; LT800P fits smaller side-by-sides. |

| Frigidaire PureSource 2 / WF2CB | Frigidaire, Electrolux, Kenmore | Inside top-left of fresh food section | Twist-off cap. WF2CB is the narrow type; PureSource 2 is wider. |

Checklist – verify before buying a replacement:

• [ ] Old part number matches a filter listed for your brand/model.
• [ ] New filter’s dimensions (length, width, connector type) match the old one.
• [ ] Housing cap unscrews or releases without forcing (check for a latch or button).
• [ ] Aftermarket filter lists NSF 42/53/401 certification (if you care about contaminant reduction claims).
• [ ] You have at least 4 gallons of drinking water to flush after installation.

Step-by-Step Replacement Process (Works for Most Brands)

Step 1: Turn off the water supply

Locate the water shut-off valve behind the refrigerator (usually a small plastic knob or a lever on the copper/braided line). Turn it clockwise to close. This prevents spurting when you remove the old filter.

Step 2: Release pressure and remove the old filter

Place a bucket or towels under the filter area.

• Twist-lock (GE, some Frigidaire): Turn the filter counterclockwise ¼ turn until it stops, then pull straight out.
• Push-button release (Whirlpool, KitchenAid, LG): Press the red or black button on the housing, then slide the filter downward or outward.
• Housing cap (older Kenmore, some GE): Unscrew the cap with a flat-head screwdriver or by hand, remove the old cartridge, and set the cap aside.
• Push-in/pull-out (Samsung DA29-00020B): Grip the filter and pull straight out—no twisting needed.

Expect a few ounces of water to drip. Let it drain fully.

Step 3: Install the new filter

Remove the protective caps from the new filter (both ends). Align the arrow or notch with the housing slot.

• Twist-lock: Insert the filter into the housing, then turn clockwise until it locks (usually ¼ turn). Listen for a click.
• Push-button: Slide the filter up into the housing until it snaps. You may need to press the release button again to seat it fully.
• Housing cap: Place the new cartridge inside, replace the cap, and hand-tighten firmly.

Step 4: Restore water and flush

Turn the water shut-off valve back on. Slowly open the refrigerator’s water dispenser (if equipped) into a large container. Flush at least 4 gallons (about two minutes of continuous flow). This clears air from the new filter and carbon fines. The water may look cloudy or black at first—that’s normal carbon dust.

Step 5: Reset the filter indicator

Most modern refrigerators have a filter change light. Press and hold the “Filter” or “Ice & Water” button on the control panel for 3–5 seconds until the light turns off or changes color. Check your manual if the reset method differs.

Where People Get Stuck (and How to Avoid It)

Failure Case #1: The filter doesn’t fit even though the part number seems right

This happens when model-year splits exist. For example, GE moved from MWF to RPWFE around 2018. A MWF filter will not lock into an RPWFE housing. Always verify the physical connector shape, not just the brand.

Fix: Compare the new filter’s length and bayonet pattern (tab positions) with the old one side by side. If they don’t match, return the filter and buy the correct variant.

Failure Case #2: Leaks after installation

Leaks usually come from:

• Missing O-rings – The new filter should have one or two rubber rings. If the old O-ring stayed in the housing, remove it.
• Filter not fully seated – For twist-lock types, if you don’t turn it far enough, the seal won’t compress. Mark the “locked” position with a piece of tape before removing the old filter.
• Damaged housing – Check for cracks around the filter port. Replace the housing if needed.

Failure Case #3: Reduced water flow

Slow dispensing often means the filter is clogged prematurely, or you didn’t flush enough and carbon fines blocked the internal screen. Also, some aftermarket filters have higher flow resistance than OEM. If flow doesn’t improve after flushing 5 gallons, try the OEM filter.

When to Stop and Call a Repairman

If you’ve tried all fixes and water still leaks, or if the filter housing is cracked, stop. Pushing a damaged housing can flood your kitchen. Turn off the water supply and contact an appliance repair professional. Housing cracks are rare, but they require a part replacement that’s best left to a technician.

Success Check – How to Know the Replacement Worked

• Water dispenses smoothly with no sputtering (air is cleared).
• No leaks after 24 hours (check the housing and filter seam with a dry paper towel).
• Filter indicator resets and stays off (or shows green/blue).
• Ice maker fills normally within 12 hours.
• Water tastes clean, no metallic or plastic aftertaste.

If any of these fail, re-check the filter seal, O-rings, and orientation. A small misalignment is the most common cause of a drip or bad flow.

FAQ – Quick Answers

Q: How often should I replace the refrigerator water filter?

A: Every 6 months or after 200 gallons of water use, whichever comes first. If you notice a drop in flow or bad taste, replace it sooner.

Q: Can I use a generic or aftermarket filter instead of the OEM brand?

A: Yes, as long as the part number compatibility matches. Look for NSF certification on the label to ensure contaminant reduction performance. Some generics may cause slightly slower flow, but they’re cost-effective.

Q: Why is water still cloudy after flushing?

A: Cloudiness is usually trapped air bubbles—shake the dispensed water in a glass; if it clears from bottom to top, it’s just air. If it remains white or black, continue flushing until clear (up to 5 gallons).

Q: My filter indicator won’t reset. What do I do?

A: Try pressing the reset button for 10 seconds. If that fails, unplug the refrigerator for 1 minute and try again. Some models require a specific sequence (e.g., press “Filter” then “Alarm”). Check the owner’s manual for your exact reset method.

Q: Do I really need to turn off the water supply?

A: Not strictly required for twist-lock or push-button filters—the shut-off valve inside the fridge stops most water. But turning off the main supply adds a safety layer if the housing cracks. Better safe than a flooded kitchen.
