TL;DR
- To change-water-filter-on-keurig, remove the filter holder from the reservoir, swap in a new cartridge, reinstall the holder, and run a plain-water cycle.
- Keurig recommends replacing the water filter cartridge about every 2 months or after about 60 tank refills, depending on use and water quality (Keurig, 2026).
- Some cartridges need a short soak or rinse before use, so check the package instructions before you install the new filter.
- A fresh filter can improve taste consistency when tap water has chlorine odor or a strong mineral taste.
- The easiest way to avoid spills is to handle the holder over a sink and fill the reservoir only after it clicks back into place.
What the Keurig Water Filter Does and Why It Matters
The change-water-filter-on-keurig process starts with a small cartridge that sits in the reservoir holder and filters the water before brewing. It helps reduce chlorine taste and odor, and that matters because coffee is mostly water.
If the water tastes off, the coffee usually does too. A new cartridge can make flavor more consistent, especially in homes that use tap water with a noticeable odor or mineral taste.

How to Remove the Filter Holder from the Reservoir
Removing the filter holder is the first hands-on step, and it usually takes less than a minute. The holder sits inside the water tank, often clipped to the side or bottom, and you need to lift it out before you can replace the cartridge.
Start by emptying the reservoir if it is full enough to spill during handling. Then reach into the tank and find the plastic filter holder assembly. Most models let you pinch or unclip the holder, then lift it straight out.
If your Keurig uses a different reservoir shape, check the manual for the exact clip location. The basic move is the same: remove the holder so you can access the old filter without forcing parts apart.
How to handle the holder cleanly
Remove the holder over a sink or towel so any drips stay off the counter. Keep the plastic frame intact, because most Keurig holders are meant to be reused with fresh cartridges rather than replaced every time.
Inspect the holder while it is out. If you see buildup, rinse the frame with cool water before installing the new cartridge. A clean holder helps the new filter sit correctly and reduces the chance of a loose fit later.
change-water-filter-on-keurig: How to Replace the Old Cartridge with a New One
Replacing the old cartridge is the main step in the change-water-filter-on-keurig process, and it should feel like a simple insert rather than a forced fit. The old cartridge usually pops out of the holder, and the new one slides into the same slot.
First, open the filter holder if your model has a two-piece design. Remove the used cartridge and check it for heavy discoloration or trapped debris, which can confirm it was due for replacement. Then place the new cartridge into the same chamber, making sure it sits flat and centered.
Do not jam the cartridge in at an angle. If the filter does not slide in easily, remove it and try again. A crooked install can block water flow or keep the holder from closing properly.
Keurig recommends replacing the water filter cartridge about every 2 months or after about 60 tank refills, depending on use and water conditions (Keurig, 2026). That schedule is a practical baseline, not a hard rule, so households that brew less often may replace less frequently.

When to Soak or Rinse the Filter Before Installation
Soaking or rinsing the cartridge is required on some models, and skipping that step can leave carbon dust or trapped air inside the filter. A short prep step helps the filter work properly once water starts moving through it.
Read the package directions before installation. Some Keurig-compatible charcoal filters need a short soak in clean water, while others only need a rinse under running water. The goal is the same: wet the media so it starts filtering cleanly and does not add loose particles to the brew path.
If a soak is required, submerge the cartridge for the time listed on the package, then drain it well. If only a rinse is required, run clean water through the filter until the initial dark rinse water clears.
Why prep matters
Activated charcoal filters can release fine black dust during shipping and storage. That dust is normal, but it should not go into your reservoir if the instructions call for rinsing first.
Think of it like rinsing a new kitchen sponge. You are not washing away the filter's function, you are clearing the loose material left from manufacturing and packaging. That small step can prevent cloudy water and first-use taste issues.
How to Reinstall the Holder and Run a Brewing Cycle
Reinstalling the holder and running a brewing cycle finishes the job, and this is where you confirm everything is seated correctly. Once the cartridge is ready, slide the holder back into the reservoir and lock it in place.
Fill the reservoir with fresh water after the holder is secured. Then run one or more brewing cycles without coffee grounds or a K-Cup, depending on your model, so the water can pass through the new filter and flush the system.
If your Keurig has a rinse or hot water function, use that first. If not, brew a plain cup of water and discard it. This first cycle helps remove any remaining loose carbon particles and confirms that water flow is normal.
What to check after reinstalling
Watch for leaks around the holder, slow flow, or unusual float movement in the tank. If the reservoir does not sit flat or the filter holder shifts when you close the lid, remove it and reinstall it before brewing again.
If the first cup has a slight charcoal taste, run another plain-water cycle. That usually clears the issue quickly. If the taste stays off after two cycles, remove the cartridge and confirm that the correct model was installed.

Common Mistakes to Avoid When Changing a Keurig Water Filter
The most common mistakes are using the wrong cartridge, skipping the rinse step, and reinstalling the holder before it clicks into place. Each one can affect water flow or taste, and all of them are easy to fix.
- Using an incompatible filter can prevent the cartridge from seating correctly, so check the model number before buying replacements.
- Skipping the soak or rinse step can leave loose carbon in the first brew, so prep the cartridge if the packaging says to do so.
- Forcing the holder into the reservoir can crack the plastic clips, so align the frame and let it lock naturally.
- Forgetting to replace the filter on schedule can reduce filter performance, so set a reminder every 2 months or after about 60 refills (Keurig, 2026).
Frequently Asked Questions About Changing a Keurig Water Filter
How often should I change the water filter in my Keurig?
Most Keurig water filter cartridges are replaced about every 2 months or after roughly 60 tank refills, depending on your machine and water use (Keurig, 2026). If your water has a strong taste or you brew often, replacing earlier can help keep coffee flavor steady.
Do I need to soak a Keurig water filter before using it?
Some models require soaking, while others only need a rinse. Check the packaging instructions before installing, because the prep step depends on the exact filter type and brand.
Can I use my Keurig without a water filter?
Yes, many Keurig machines will brew without the filter installed, but the water will not be filtered first. If your tap water has a strong taste or odor, leaving the filter out may affect coffee flavor.
What happens if I do not replace the filter on time?
An old filter may stop reducing taste and odor as well as it did when new. You may notice flatter coffee, more mineral buildup, or slower water flow over time.
How do I know if the filter is installed correctly?
The holder should sit flat, lock into place, and stay stable when the reservoir is filled. If it shifts, leaks, or blocks the tank from seating properly, remove it and reinstall it.
Can I clean and reuse the old Keurig filter cartridge?
No, the cartridge is a replacement item, not a washable part. You can rinse the holder frame, but the filter media inside the cartridge should be replaced rather than reused.
Key Takeaways
- To change-water-filter-on-keurig, remove the holder, swap in a new cartridge, prep it if needed, and reinstall it before brewing.
- Replacing the cartridge about every 2 months or after about 60 tank refills is a practical schedule for most users (Keurig, 2026).
- A proper rinse or soak, when required, helps prevent loose carbon dust from affecting the first cup.
- The first brew cycle after installation is a quick check for leaks, flow issues, and leftover taste from the new filter.
