Locating the Water Filter in Your Keurig Coffee Maker

Quick answer

• The water filter in most Keurig machines is located in the water reservoir.
• You’ll usually find it at the bottom of the reservoir, attached to a plastic tube.
• Some models have a filter holder that clicks into place.
• Always unplug your Keurig before attempting to access or change the filter.
• Check your specific model’s manual if you’re having trouble finding it.
• A clean filter helps ensure better-tasting coffee and keeps your machine running smoothly.

What this problem usually is (and is not)

• This is usually about finding the physical location of the water filter, not a malfunction of the machine.
• It’s not about a clogged filter causing brewing issues, though that’s a related topic.
• We’re talking about the where, not the why it’s not working.
• This guide assumes your Keurig has a water filter feature. Some older or simpler models might not.
• It’s also not about the charcoal pods that some people use instead of a built-in filter.
• We’re focusing on the integrated filter system.

Likely causes (triage list)

Water Reservoir Location:

• The water reservoir is the removable tank where you pour your water. It’s usually on the side or back of the machine.
• Confirm you’re looking at the right part of the machine.

Filter Attachment Point:

• The filter is almost always attached to the intake tube that draws water from the reservoir into the machine.
• Look for a small plastic housing at the bottom of the reservoir.

Filter Type:

• Keurig uses specific filter types. Some are simple cartridges, others might have a small holder.
• Make sure you have the correct replacement filter for your model.

Machine Model Variations:

• Keurig has many models. The exact placement can vary slightly.
• A quick glance at your machine’s exterior should confirm it has a removable reservoir.

Filter Holder Design:

• Some filters just slide on, others have a twist-and-lock mechanism.
• This is more about how it’s secured than where it is.

Lack of Filter:

• It’s possible your machine didn’t come with a filter, or it was never installed.
• Check the parts that came with your Keurig when you bought it.

Fix it step-by-step (brew workflow)

1. Unplug the Machine:

• What to do: Disconnect the power cord from the wall outlet. Safety first, always.
• What “good” looks like: The machine is completely dead, no lights or sounds.
• Common mistake: Forgetting to unplug. This is a simple step, don’t skip it.

2. Remove the Water Reservoir:

• What to do: Gently lift the water reservoir straight up and away from the Keurig base.
• What “good” looks like: The reservoir is free from the machine and you can hold it in your hand.
• Common mistake: Trying to force it off or twisting it. Most reservoirs lift straight up.

3. Locate the Filter Assembly:

• What to do: Turn the reservoir upside down. Look at the bottom where the water spout is. You should see a plastic tube extending down. The filter is attached to this tube.
• What “good” looks like: You see a small, often white or blue, plastic housing connected to the water intake tube.
• Common mistake: Mistaking the water intake tube itself for the filter. The filter is a separate piece that attaches to it.

4. Identify the Filter Type:

• What to do: Observe how the filter is attached. Is it a simple push-on? Does it have a cap that needs to be removed first?
• What “good” looks like: You understand the connection mechanism.
• Common mistake: Trying to pull a filter off that’s designed to twist or vice-versa.

5. Remove the Old Filter (if present):

• What to do: Gently pull or twist the old filter off the intake tube according to its design. If it’s a new machine or you’ve never had one, skip this.
• What “good” looks like: The old filter is detached, leaving the intake tube clear.
• Common mistake: Yanking too hard and potentially damaging the intake tube. Be firm but gentle.

6. Prepare the New Filter:

• What to do: If your new filter requires soaking or rinsing, do that now according to the filter’s instructions. This is crucial for charcoal filters.
• What “good” looks like: The filter is ready for installation, properly prepped.
• Common mistake: Installing a new filter without soaking or rinsing it. This can lead to loose charcoal particles in your coffee.

7. Attach the New Filter:

• What to do: Firmly push or twist the new filter onto the water intake tube. Ensure it’s secure.
• What “good” looks like: The filter is snugly attached and won’t easily come off.
• Common mistake: Not seating the filter properly. It needs to be fully engaged for a good seal.

8. Reinstall the Water Reservoir:

• What to do: Carefully place the reservoir back onto the Keurig base. Make sure it clicks or sits flush.
• What “good” looks like: The reservoir is seated correctly and stable.
• Common mistake: Not aligning the reservoir properly, which can cause leaks.

9. Refill the Reservoir:

• What to do: Fill the reservoir with fresh, cold water.
• What “good” looks like: The reservoir is filled to the desired level.
• Common mistake: Overfilling the reservoir, which can spill when you place it back on the machine.

10. Plug In and Prime:

• What to do: Plug the Keurig back into the wall. Run a cycle with just water (no pod) to flush the new filter and system. Discard this water.
• What “good” looks like: The machine powers on, and you get hot water from the dispenser.
• Common mistake: Skipping the priming cycle. This ensures the filter is clean and the machine is ready.

Prevent it next time

• Clean the Reservoir Weekly: Wash it with mild soap and water.
• Descale Every 3-6 Months: Use a descaling solution or vinegar mix. Check your manual.
• Replace Filters Regularly: Usually every 2 months, or when recommended by the filter packaging.
• Use Filtered Water: If your tap water is hard, consider using filtered water even with the machine’s filter.
• Store Water Properly: Keep water in the reservoir covered or use filtered water from a pitcher.
• Inspect the Filter: Before installing a new one, check the old one for any unusual buildup.
• Handle with Care: Don’t force components when cleaning or changing the filter.
• Listen to Your Machine: If brewing time changes or the machine sounds strained, it might be time for maintenance.
• Keep it Dry: Ensure the exterior of the machine is dry after cleaning.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not unplugging the machine	Risk of electric shock.	Always unplug before any maintenance.
Forgetting to soak/rinse new filter	Charcoal dust in coffee, off-taste.	Follow filter instructions for soaking/rinsing before installation.
Not seating the filter properly	Leaks from the reservoir or poor water flow.	Push or twist the filter until it’s firmly seated.
Using the wrong replacement filter	Filter won’t fit, leaks, or doesn’t filter effectively.	Always check your Keurig model number and buy the correct filter.
Skipping the priming brew cycle	Initial brews might taste slightly off from filter material.	Run at least one full brew cycle with just water after installing a new filter.
Overfilling the water reservoir	Spills when placing reservoir back on the machine, potentially damaging it.	Fill the reservoir to the max line, but don’t go over.
Using harsh chemicals to clean	Can damage plastic components or leave residue.	Stick to mild dish soap and water for the reservoir, and approved descaling solutions for the machine.
Not descaling regularly	Mineral buildup can clog the machine, affect taste, and shorten its life.	Descale every 3-6 months as per your manual.
Leaving old water in the reservoir	Stale taste, potential for bacterial growth.	Empty and rinse the reservoir if the machine won’t be used for a few days.
Forcing the reservoir off/on	Broken plastic clips or reservoir damage.	Lift reservoirs straight up; ensure they seat properly without force.

Decision rules (simple if/then)

• If you see a white or blue plastic piece attached to the water intake tube in the reservoir, then you have a water filter.
• If the filter doesn’t easily come off, then check the filter packaging or your Keurig manual for removal instructions.
• If your new filter requires soaking, then do not skip this step because it removes loose charcoal.
• If the filter feels loose after installation, then remove it and reattach it more firmly.
• If you’re unsure about your specific Keurig model’s filter location, then consult the owner’s manual.
• If you notice a plasticky or papery taste in your coffee, then it’s likely time to replace the water filter.
• If your machine is brewing slowly or making strange noises, then check if the water filter needs replacing or if the machine needs descaling.
• If you can’t find a filter housing in your reservoir, then your Keurig model might not use an internal water filter.
• If you’ve just installed a new filter and the first brew tastes odd, then run another brew cycle with just water to flush it out.
• If you’re storing your Keurig for an extended period, then empty the reservoir and remove the filter to prevent drying out or mold.
