Where is the Keurig water filter located?

The Keurig water filter is located inside the removable water reservoir of the Keurig coffee maker. It is typically found on the inside wall of the reservoir, near the bottom. The filter should be replaced every two months or after every sixty liters of water used. To replace the filter, the user should remove the reservoir, remove the old filter, and insert the new filter. The user should then reattach the reservoir to the machine and run two to three tanks of water through the machine to flush out any impurities.

How to replace a Keurig water filter – 3 Simple Steps

Replacing the water filter in your Keurig coffee maker ensures that your coffee is clean and tastes great.

Step 1: Remove the old filter

To access the water filter, you must first remove the top of Keurig’s water reservoir. With this, you can have access to the filter. It doesn’t matter if the reservoir is full or empty. It can be done either way.

Remove the old filter from Keurig

1.1. Take off the Keurig water tank’s cover

To remove the upper filter holder from the reservoir, grab its handle and pull it up. Plastic tabs on the reservoir’s base will engage with the bottom of the filter holder device, securing it in place. You may need to jiggle the filter-holder device back in place or push it hard to dislodge it.

1.2. Remove the used filter by opening the holder

To close the filter unit’s tabs, pinch them together with your thumb and index finger. First, pull down to open the lower filter holder to remove the old filter. Your kitchen trash container is fine for disposing of the old filter.

Step 2: Install the new filter

2.1. Filter should be soaked in water

Once you’ve obtained your replacement filter, you should let it submerge in water for 5-10 minutes before giving it a quick cleaning under running water for 60 seconds. This step will remove the excess carbon dust from the charcoal filter.

2.2. Alter the filter in the filter housing

The fresh filter is put into the filter holder with the rounded top facing up. Arrange the lower filter holder directly below it, and then snap its two sides into position around the filter.

Reattach the Keurig filter in the filter housing

2.3. Set the replacement dial 2 months forward

The filter replacement unit’s replacement dial is situated atop its handle. The numbers 1 through 12 will be displayed (each of which stands for the corresponding month).

Set the Keurig replacement dial 2 months forward

2.4. Schedule a filter change reminder on your Keurig

Turn the dial two months ahead of the current month by turning it clockwise.

With this option, the Keurig will send you a digital reminder in two months. However, a reminder must be manually scheduled. Select “Water Filter Reminder” from the “Settings” menu to accomplish this. To turn it on, click the “Enable” button.

Step 3: Verify the positioning with care

Place the Keurig water filter device into the Keurig reservoir.

The last step is to install the Keurig water filter device into the water tank. When the lower filter holder is placed firmly into the reservoir’s bottom, the exterior side should snap into place.

Verify the Keurig's positioning with care

Make sure the grooves on the lower filter holder are lined up with the raised plastic on the floor of the Keurig’s water reservoir, then try reinstalling the filter to see if it clicks into place.

A vital aspect of routine maintenance for your Keurig coffee maker is changing the water filter. If you follow these instructions, you can guarantee that your coffee will always taste great.
