That little blinking light on your refrigerator’s dispenser isn’t just a friendly reminder—it’s your gateway to better-tasting, cleaner water and ice. For many, the thought of appliance maintenance can feel a bit daunting, but learning How To Replace Refrigerator Water Filter is one of the easiest, most satisfying DIY tasks you can do. It’s a five-minute job that pays you back with every glass of water you drink. Think of it less as a chore and more as a quick upgrade for your kitchen and your health. This guide will walk you through every step, turning you from a novice into a filter-swapping pro in no time.
Why Bother Changing Your Water Filter Anyway?
It’s a fair question. The water still comes out, right? But what’s in that water is the real story. Over time, that tiny filter is working hard, and just like any filter, it gets clogged. Here’s the lowdown on why staying on top of this simple task is a game-changer.
- Purity and Taste: The primary job of your filter is to trap contaminants. We’re talking chlorine, lead, mercury, sediment, and other nasty stuff you don’t want in your morning coffee. As the filter ages, its ability to catch these particles diminishes, which can lead to water that tastes or smells “off.”
- Appliance Protection: A clogged filter can reduce water flow to your ice maker and dispenser. This strain can potentially damage the internal mechanisms of your refrigerator over the long haul. A fresh filter ensures everything runs smoothly.
- Peace of Mind: Knowing that the water your family is drinking is clean and filtered is a simple but powerful comfort. It’s a small step that makes a big difference in your daily routine.
How Often Should You Replace Your Refrigerator Water Filter?
The general rule of thumb is to replace your refrigerator water filter every six months. Most refrigerator manufacturers, like Samsung, LG, and Whirlpool, recommend this timeline, and it’s typically when that reminder light will pop on.
However, this isn’t a one-size-fits-all answer. You might need to change it more frequently if:
- You have “hard” water with a lot of mineral content.
- Your household goes through a large volume of water and ice.
- You notice a decrease in water flow or a change in taste before the six-month mark.
“A common mistake people make is ignoring the ‘change filter’ light. That filter is full of everything it has successfully removed from your water over the last six months. Flushing the new filter for a few minutes after installation is also critical—it activates the carbon and clears out any loose particles from manufacturing.” – David Chen, Senior Appliance Engineer
Finding the Right Filter: A Quick Buyer’s Guide
Before you can learn how to replace refrigerator water filter, you need the right replacement part. Using the wrong filter can lead to leaks and improper filtration. Here’s how to make sure you grab the correct one.
Find Your Refrigerator’s Model Number
First things first, you need your fridge’s model number. Look for a sticker on the inside wall of the refrigerator compartment, usually near the top. It might also be on the door jamb or behind the crisper drawer. Once you have that number, you can easily find the corresponding filter model.
OEM vs. Aftermarket Filters: What’s the Difference?
You’ll encounter two main types of filters:
- OEM (Original Equipment Manufacturer): These are made by your refrigerator’s brand (e.g., a Samsung filter for a Samsung fridge). They are guaranteed to fit and perform to the manufacturer’s specifications and are often NSF certified for contaminant reduction.
- Aftermarket (or Generic): These are made by third-party companies and are typically more budget-friendly. Many are high-quality and also NSF certified, but it’s crucial to buy from a reputable brand to ensure a proper fit and effective filtration.
For peace of mind, especially for your first replacement, an OEM filter is a safe bet.

Your Step-by-Step Guide on How to Replace Refrigerator Water Filter
Alright, you’ve got your new filter in hand. Let’s get to it. The process varies slightly depending on the filter’s location and type, but the core steps are largely the same. Most modern refrigerators don’t even require you to turn off the water supply!
For Twist-In Filters (Usually in the Grille or Inside)
These are one of the most common types, often found in the base grille at the bottom of the fridge or inside at the top-right corner.
- Locate the Filter: Find the round cap or cover. If it’s in the grille, you might see a button to press that ejects the filter slightly.
- Twist to Remove: Turn the old filter counter-clockwise about a quarter turn. You should feel it unlock.
- Pull Straight Out: Gently pull the filter straight out. A small amount of water might drip out, so having a towel handy is a good idea.
- Prepare the New Filter: Remove the protective cap from the end of the new filter.
- Insert and Twist: Align the new filter with the housing and push it in firmly. Then, turn it clockwise until it locks into place. You should feel a solid click.
- Flush the System: This is a crucial step. Dispense about 3-4 gallons of water through the system to flush out any air and loose carbon particles. The water may look cloudy or sputter at first—this is completely normal.
- Reset the Filter Light: Most fridges have a button you’ll need to press and hold for three seconds to reset the reminder light. Check your owner’s manual if you’re unsure which button it is (it’s often the “Ice Type” or “Lock” button).
For Push-In Filters (Often Inside the Fridge)
These filters are typically long and skinny, located inside the refrigerator compartment in a covered housing.
- Open the Housing: Locate the filter compartment. There might be a tab to press or a door that flips down to reveal the filter.
- Push to Release: Gently push the end of the old filter to disengage it from the locking mechanism. It should pop out slightly.
- Pull it Out: Grab the end of the filter and pull it straight out. Again, keep a towel ready for minor drips.
- Unpack the New Filter: Take off any plastic wrapping or protective caps from the new filter.
- Push to Install: Slide the new filter into the housing until you hear or feel it click securely into place.
- Close the Housing: Shut the compartment door.
- Flush and Reset: Just like with the twist-in style, run 3-4 gallons of water through the dispenser and then reset the filter indicator light on your control panel.
What If Something Goes Wrong? Common Troubleshooting Tips
Learning how to replace refrigerator water filter is usually a breeze, but occasionally you might hit a snag. Here are solutions to common issues:
- The filter won’t come out: It might be stuck due to water pressure. Try dispensing a bit of water to relieve the pressure, then attempt to remove it again. A gentle but firm twisting motion is key.
- The new filter is leaking: This is almost always due to improper installation. Remove the filter and try re-installing it, making sure it’s fully seated and locked. If it continues to leak, you may have the wrong model or a defective filter.
- Water flow is slow after replacement: The system might have air trapped in the lines. This is common and usually resolves itself after flushing the system thoroughly.
- The “Change Filter” light won’t reset: Make sure you are pressing and holding the correct button(s) for at least 3-5 seconds. Every brand has a slightly different reset procedure, so your owner’s manual is your best friend here.
Frequently Asked Questions (FAQ)
Q: What happens if you don’t change your refrigerator water filter?
A: If you don’t change your filter, it will become saturated with contaminants and stop filtering your water effectively. This can lead to poor-tasting water and ice, reduced water flow, and potential strain on your refrigerator’s water system.
Q: Can I use my refrigerator without a water filter?
A: Some models require a filter to be installed for the water dispenser to work. Others may offer a bypass plug that you can install in place of the filter. Check your owner’s manual, as running the system without a filter or a bypass plug can cause serious leaks.
Q: Why is my water cloudy after changing the filter?
A: Cloudy water right after a filter change is perfectly normal. It’s caused by tiny air bubbles trapped in the water lines and loose carbon particles from the new filter. Flushing the system by dispensing a few gallons of water will clear it up.
Q: Are expensive refrigerator water filters better?
A: Not necessarily. The most important factor is NSF certification, which guarantees the filter is tested to remove the contaminants it claims to. While OEM filters are a safe bet, many reputable aftermarket brands offer the same level of certification for a lower price.
Q: Does the water filter affect the ice maker?
A: Yes, absolutely. The water used to create ice cubes runs through the same filter. A fresh filter ensures you have clear, clean, and great-tasting ice without any freezer-aisle funk.
