If you are not sure which refrigerator water filter your fridge uses, the fastest way to avoid buying the wrong replacement is to find the filter model number first. Most refrigerators list the correct filter model on the old filter, inside the fridge, or in the owner’s manual.

Check the Old Water Filter First
The easiest way to find the correct refrigerator water filter model is to remove the current filter and look for the part number printed on the label. Common filter numbers include MWF, XWF, RPWFE, EDR1RXD1, LT1000P, LT800P, HAF-QIN, and ULTRAWF.
Look Inside the Refrigerator
Many refrigerators include a sticker or label inside the fresh food section that shows the correct water filter model. Check near the crisper drawers, side walls, or filter housing area.
This guide will show you how to find the correct refrigerator water filter model so you can choose the right replacement with confidence.
Using the wrong filter may result in leaks, poor water flow, or improper filtration. Before ordering a replacement, it’s important to confirm the exact filter model your refrigerator uses.
Use Your Refrigerator Model Number
If you cannot find the filter number directly, locate your refrigerator model number and search for the correct compatible filter based on that model. The refrigerator model number is often found on a sticker inside the refrigerator compartment.

How Often Should You Replace a Refrigerator Water Filter?
Most refrigerator manufacturers recommend replacing your water filter every 6 months. However, replacement frequency can vary depending on water usage and water quality.
You may need to replace your filter sooner if:
• Water flow slows down
• The water tastes or smells different
• Your refrigerator displays a filter replacement indicator
Replacing your filter on schedule helps maintain water quality and protects your refrigerator’s internal system.
Final Tip Before Ordering
Before placing an order, double-check the SKU printed on your current filter. Even filters from the same brand may not be interchangeable.
