September is a good time to get back into household routines after summer, and your refrigerator deserves a place on that checklist. One small component that is easy to forget is the refrigerator water filter. Your fridge may continue dispensing water even when the filter has been installed for months. But that does not necessarily mean the filter should keep being used indefinitely. So, how often should you change your refrigerator water filter? For many refrigerators, manufacturers commonly recommend replacing the water filter around every six months, although the correct interval can vary based on the refrigerator model, household water usage and local water conditions.
If you cannot remember the last time yours was replaced, these seven signs can help you decide whether it is time to check the filter.
1. Your Water Dispenser Is Flowing More Slowly
One of the most noticeable signs of a restricted refrigerator water filter is slower water flow. As the filter collects particles over time, water may have more difficulty passing through it. You might notice:
- The dispenser takes longer to fill a glass
- Water pressure seems weaker than before
- The ice maker produces ice more slowly
- Ice cubes may become smaller on some refrigerators
Before assuming there is a major refrigerator problem, inspect the water filter first. If replacing the filter does not restore normal flow, the issue could be somewhere else in the water supply system.

2. Your Refrigerator Water Tastes Different
A change in taste is another reason to check the filter. Refrigerator water filters are designed to reduce specific substances according to the filter's design and certification. As the filter reaches the end of its recommended service life, its performance may change. If the water suddenly tastes different from what you normally expect, check:
- How old the current filter is?
- Whether the filter indicator is on
- Whether the cartridge is installed correctly
- Whether the replacement filter is correct for the refrigerator mode
Do not choose a new filter based only on appearance. Many cartridges look very similar but use different connectors, locking tabs, and housings.

3. The Water or Ice Has an Unusual Odour
Water or ice that develops an unusual smell deserves attention. Before blaming the refrigerator itself, check whether the water filter is overdue for replacement. You should also clean the ice bin and dispenser area because odours from food, spills or the refrigerator compartment can sometimes affect what you notice. Some refrigerators also use a separate air filter to help manage odours inside the fresh-food compartment.
4. The Filter Indicator Light Is On
Many modern refrigerators include a filter reminder on the control panel. Depending on the brand and model, the indicator may:
- Change colour
- Turn red
- Display a filter message
- Illuminate a filter symbol
Do not ignore the reminder indefinitely. Samsung Canada, for example, recommends replacing refrigerator water filters approximately every six months and explains how the filter reminder can help track replacement timing. Remember that resetting the indicator does not replace the filter. Reset it only after the appropriate maintenance has been completed according to your refrigerator's instructions.
5. It Has Been Around Six Months Since Your Last Replacement
Can't remember seeing any obvious symptoms? Check the date instead.
A six-month replacement interval is common among major refrigerator manufacturers. Whirlpool Canada recommends changing many of its refrigerator water filters every six months, while also noting that conditions and symptoms such as reduced dispensing performance can indicate that attention is needed. However, six months should not be treated as a universal rule for every filter.
Always check:
- Your refrigerator owner's manual
- Instructions supplied with the filter
- The manufacturer's recommended capacity
- Your household's water usage
- Local water conditions
A household that uses the refrigerator dispenser throughout the day may reach a filter's capacity differently from a household that uses it occasionally.
6. Your Ice Production Has Changed
The water filter can affect more than the drinking-water dispenser. On refrigerators where filtered water supplies the ice maker, a heavily restricted filter may contribute to reduced water flow.
Possible symptoms can include:
- Smaller ice cubes
- Slower ice production
- Hollow or irregular cubes
- Longer refill cycles
However, the filter is only one possible cause. Ice-maker problems can also involve:
- Water inlet valves
- Frozen water lines
- Low household water pressure
- Ice-maker components
- Temperature-related issues
If a new filter does not resolve the problem, further troubleshooting may be required.

7. You Do Not Know When the Filter Was Last Changed
This one is simple. If you moved into a new home, bought a used refrigerator or simply cannot remember the last replacement date, inspect the cartridge.
Look for:
- A replacement-date sticker
- Filter model or part number
- Refrigerator filter indicator
- Installation records
- Manufacturer instructions
If you cannot confirm the filter's history, checking the correct replacement interval for your specific refrigerator is a sensible next step. Once you replace it, record the installation date somewhere easy to remember. You could add a reminder to your calendar for the manufacturer's recommended replacement date.
How to Find the Right Refrigerator Water Filter?
One of the biggest mistakes when buying a fridge filter is assuming that similar-looking cartridges are interchangeable. They are not. Quick Parts Depot carries refrigerator water filters for several major appliance brands, including options associated with LG, Samsung, Whirlpool, Frigidaire, GE, Bosch and other refrigerator models. Before ordering, check the following two pieces of information.
1. Find the Existing Filter Number
Remove or inspect your current cartridge and look for the part or filter number printed on it.
Examples may include numbers such as:
- LT700P / ADQ36006101
- WF3CB
- EPTWFU01C
- EDR1RXD1B
- MWF
- DA29-00020B
- EDR3RXD1B
Please note that these are examples of filter families currently represented in Quick Parts Depot's refrigerator water filter selection.
2. Check Your Refrigerator Model Number
Do not rely on the filter shape alone. Find the model label inside or around your refrigerator and compare the model number with the compatibility information provided for the replacement filter. Whirlpool also advises using the refrigerator model number to identify the appropriate filter because filter requirements vary between appliances.
Should You Replace a Fridge Filter Before It Reaches Six Months?
Yes, you can replace a fridge filter before it turns six months. The recommended replacement interval is a guideline specific to the filter and refrigerator.
Consider checking it earlier when:
- Water flow becomes noticeably slower
- The refrigerator sees unusually heavy dispenser use
- Water taste or odour changes
- The manufacturer recommends an earlier change
- The filter reaches its stated water capacity
- Your local water conditions cause faster buildup
Always prioritize the instructions for your specific refrigerator and filter.
What Should You Do After Installing a New Refrigerator Water Filter?
Installation instructions vary between brands and models, so follow your refrigerator owner's manual. Many manufacturers also instruct users to flush water through the system after installing a new filter. The amount varies.
For example, Samsung Canada's current replacement instructions include flushing the system after installing a new filter, while Whirlpool also provides model/filter-specific flushing guidance.
Flushing can help remove trapped air and loose carbon particles associated with a newly installed filter.
After installation:
- Confirm the filter is securely locked into place.
- Restore the water supply if it was turned off.
- Flush the system according to manufacturer instructions.
- Check around the filter housing for leaks.
- Reset the filter indicator if your refrigerator has one.
- Record the replacement date.
September Refrigerator Check: Make the Water Filter Part of Your Fall Routine

Check your:

- Unusual noises or leaks
A few minutes of inspection can help identify small maintenance needs before they become frustrating appliance problems.
