That crisp, cool water from your fridge dispenser is a daily luxury, isn’t it? It’s the go-to for a quick glass of water, filling up the coffee pot, or making crystal-clear ice. But have you ever stopped to think about the unsung hero behind that refreshing taste? Buried inside your fridge is a small but mighty filter working tirelessly. Knowing How To Change A Refrigerator Water Filter is one of the simplest yet most impactful things you can do for your family’s health and the longevity of your appliance. It might seem like a chore, but trust me, it’s a piece of cake once you know the ropes.
Did you know that after about six months, your filter can become so saturated with contaminants that it stops working effectively? It can even become a breeding ground for bacteria. That thought is enough to make anyone want to learn this simple skill. Let’s walk through it together.
Why Changing Your Refrigerator Water Filter is Non-Negotiable
It’s easy to fall into the “out of sight, out of mind” trap with your fridge filter. The indicator light might be nagging you, but it’s just one more thing on the to-do list. However, procrastinating on this small task has bigger consequences than you might think.
Think of your water filter like a microscopic sponge. As water from your tap flows through it, the filter, typically made of activated carbon, grabs onto all sorts of undesirable things. This process is crucial for improving not just the taste and smell of your water but also its safety.
Here are just a few of the common contaminants a quality refrigerator filter helps remove:
- Chlorine: The primary culprit behind that “tap water” taste and smell.
- Lead: A dangerous heavy metal that can leach from old plumbing.
- Mercury: Another heavy metal with serious health risks.
- Cysts: Microscopic parasites like Giardia and Cryptosporidium.
- Pharmaceuticals: Trace amounts of medications that can find their way into water supplies.
- Herbicides and Pesticides: Runoff from agriculture can contaminate water sources.
“A refrigerator water filter is your last line of defense before the water hits your glass. Over time, that defense weakens as the filter becomes clogged. Regularly changing it isn’t just about maintenance; it’s a proactive step for your family’s well-being.”
– Dr. Eleanor Vance, Water Quality Specialist
Ignoring a filter change means you could be drinking the very contaminants you thought you were avoiding. Worse, a clogged filter can reduce water flow to your dispenser and ice maker, putting unnecessary strain on your refrigerator.
How Often Should You Change a Refrigerator Water Filter?
The general rule of thumb is to change your refrigerator water filter every six months. This is the standard recommendation from most manufacturers and is based on average household usage and water quality.
However, this isn’t a one-size-fits-all answer. You might need to change it more frequently if:
- You have a large family: More people means more water and ice consumption, exhausting the filter’s capacity faster.
- Your tap water quality is poor: If you live in an area with particularly “hard” water (high mineral content) or known contaminants, your filter has to work overtime.
- You notice a change: The most telling sign is a change in your water. If you notice the taste or odor of chlorine returning, or if the water flow from the dispenser slows to a trickle, it’s definitely time for a replacement.
Gearing Up: What You’ll Need Before You Start
The good news is that you don’t need a plumber or a full toolbox for this job. The process is designed to be user-friendly.
Here’s what you’ll typically need:
- The new replacement filter: This is the most crucial part! Make sure you have the correct model for your refrigerator. Check your fridge’s user manual or look at the model number on the old filter.
- A dry towel or two: A little water spillage is common, so it’s wise to have a towel on hand to place under the filter area.
- A sturdy glass or pitcher: You’ll need this for flushing the new filter after installation.
A Quick Word on Filters: OEM vs. Aftermarket
You’ll see two main types of filters: OEM (Original Equipment Manufacturer) and aftermarket (or generic). OEM filters are made by your refrigerator’s brand (e.g., Samsung, LG, Whirlpool). They guarantee a perfect fit and are certified to meet specific performance standards, like those from NSF International. Aftermarket filters are often cheaper but can vary in quality. If you opt for an aftermarket filter, ensure it is NSF/ANSI certified to guarantee it effectively removes the contaminants it claims to.

The Main Event: How to Change a Refrigerator Water Filter Step-by-Step
Alright, let’s get down to business. While every refrigerator is slightly different, most filters fall into one of a few common types. Find the one that matches yours. Don’t forget to place your towel down first!
Type 1: The Push-In Filter (Often in the top-right corner)
This style is common in side-by-side and French door models. The filter housing usually has a push-button or a flip-down door.
- Locate the filter housing: It’s typically in the upper-right interior corner of the fridge.
- Release the old filter: Press the eject button or push gently on the filter itself. It should pop out slightly.
- Remove the old filter: Pull the filter straight out. A small amount of water might drip out, which is what the towel is for.
- Prepare the new filter: Remove any protective caps from the end of the new filter.
- Insert the new filter: Align the new filter with the housing and push it in firmly until you hear or feel it click into place.
- Close the housing: If there’s a cover, snap it back into place.
Type 2: The Twist-On Filter (Often in the base grille)
Many refrigerators have a filter located in the grille at the bottom of the unit.
- Locate the filter: It’s usually a round knob or cap in the bottom front grille.
- Release the old filter: Turn the knob counter-clockwise about a quarter-turn until it pops loose. You might need to push a button to release it first.
- Remove the old filter: Pull the filter straight out.
- Prepare the new filter: Remove the protective cap. Some models require you to transfer a decorative cap from the old filter to the new one. It usually just pulls off and snaps on.
- Insert the new filter: Push the new filter into the housing and turn it clockwise until it locks securely.
- Ensure it’s secure: The knob or cap should be aligned as it was originally.
Type 3: The Drop-Down Filter (Often inside, at the top)
This is another common interior style, similar to the push-in but with a slightly different mechanism.
- Locate the filter housing: Find the covered compartment, often between the crisper drawers or in the top ceiling of the fridge.
- Open the housing: Unlatch or pull down the cover.
- Release the old filter: Twist the filter about a quarter-turn counter-clockwise. It will drop down slightly.
- Remove the old filter: Pull it straight out.
- Insert the new filter: With the protective caps removed, insert the new filter and twist it clockwise until it feels snug and locked.
- Close the housing: Push the housing back up until it clicks shut.
The Final, Crucial Steps (For All Filter Types!)
You’re not quite done yet! These last two steps are essential for proper performance.
- Flush the System: Grab your large glass or pitcher and dispense about 3-4 gallons of water through the system. The first few glasses might look cloudy or discolored—this is completely normal. It’s just harmless carbon dust from the new filter. Flushing clears it out and activates the carbon.
- Reset the Filter Indicator Light: Most refrigerators have a light that reminds you to change the filter. You’ll need to reset it manually. This process varies by brand, but it usually involves pressing and holding a combination of buttons (like “Ice Type” and “Child Lock” simultaneously for 3-5 seconds). Check your user manual if you’re unsure.
Common Hiccups and How to Fix Them
Sometimes things don’t go perfectly. Here are a few common issues and what to do.
- The filter won’t come out: Don’t force it! It might be stuck due to water pressure. Try dispensing some water to relieve the pressure, then try again. A gentle wiggle can also help.
- The new filter is leaking: This is almost always because the filter isn’t fully seated or locked in. Remove it and try re-installing it, ensuring you hear a “click” or feel it lock firmly into place.
- Water is dispensing slowly or sputtering: This is expected right after installation. It’s just air in the lines. Flushing the system for a few minutes as instructed above should resolve it.
Frequently Asked Questions (FAQ)
What happens if I never change my refrigerator water filter?
If you don’t change your filter, it will become clogged with contaminants. This can cause it to stop filtering effectively, re-releasing impurities into your water. It can also lead to slow water flow, a bad taste or smell, and put strain on your refrigerator’s water system.
Can a clogged water filter damage my refrigerator?
Yes, a severely clogged filter can restrict water flow to the ice maker, potentially damaging it over time by forcing the components to work harder. It can also cause pressure buildups in the water lines.
Is an expensive OEM filter really better than a generic one?
OEM filters are guaranteed to fit and perform to the manufacturer’s specifications, often with NSF certifications to back up their claims. While some high-quality aftermarket filters perform well, others may not filter as effectively or fit properly. For peace of mind, an OEM or a highly-rated, NSF-certified alternative is the safest bet.
Why is my water cloudy after changing the filter?
Cloudy water immediately after a filter change is perfectly normal. It’s caused by tiny air bubbles and harmless carbon dust from the new filter. Flushing about 3-4 gallons of water through the dispenser will clear this up completely.
How do I know which replacement filter to buy?
The best way is to check your refrigerator’s user manual. You can also remove the current filter and look for a model number printed on it. Many online retailers have tools where you can enter your refrigerator’s model number to find compatible filters.
