Where is the water filter on a Keurig coffee maker?
The Keurig water filter is located in the water tank. The Keurig water filter fits into the pocket at the bottom of a vertical plastic handle on the water reservoir. Depending on the Keurig model, the plastic handle is either short or long.
To access the water filter on a Keurig coffee maker, simply pull up on the plastic bracket, then press down on the two tabs on the bottom while pulling on the handle to remove the bottom cover. The bottom cover should slide on easily, but if it's too tight, press down on the tabs and wiggle them around while pulling the two pieces apart.
Some Keurig models like the Keurig K-Duo Special Edition do not come with a water filter, but you can purchase one separately. So don't be alarmed if you can't find a water filter on your new Keurig coffee maker.
You may want to double-check the packing slip to confirm the accessories that came with the Keurig, especially when shopping online.
What do Keurig water filters do?
A Keurig water filter captures and removes dirt, residual chlorine, odors, and tastes from raw water. This is done in the water tank so that only filtered water flows through the water lines into the K cup or ground coffee for a clean brew.
Without a water filter, your coffee can become moldy and have a chlorine taste. Also, particles from the unfiltered water are likely to get trapped in the water pipes and affect the flow of water.
Chlorine and chemical residues are likely to gradually degrade your Keurig's plastic lines and possibly leak over time.
What is a Keurig Water Filter Starter Kit?
The basic Keurig water filter kit includes a plastic handle or holder and at least one activated carbon filter. The plastic handle has a pocket with a lid at the bottom and a calendar wheel at the top where you can schedule your next appointment to change the carbon filter.
There are two types of Keurig water filter starter kits:
- The Keurig Rear Tank Water Filter Starter Kit. Has a short-handled plastic holder compatible with Keurig machines that use a rear water tank
- The Keurig Starter Water Filter Kit with Side Reservoir. It has a long-handled plastic support compatible with Keurig coffee makers that have a side water tank
The difference between the rear and side water filters is obviously the size of the plastic holder. The charcoal filter is one size fits all, so it fits perfectly in both high and low plastic holders.
Important Tips for Buying Keurig Water Filters
To avoid buying a Keurig water filter starter kit that won't fit your brew machine
- Identify the location (back or side) of the water tank on your Keurig. If it's a multi-position tank like the K-Duo Plus, think of it as a side water tank
- Check the height of your water tank. For water tanks less than 8.0 inches in height, a short handle starter kit is used and vice versa

Final Thoughts on Where to Find the Keurig Water Filter
The charcoal water filter is located at the bottom of the vertical plastic bracket inside the Keurig water tank. To access the filter, you must remove the clear plastic handle of the filter from the water, and then open the lid at the bottom.
There are two types of Keurig water filters;
- Rear tank water filter compatible with Keurigs with short water tanks or water tanks located at the back of the brewer
- the side water filter compatible with Keurigs with tall or side water tanks
Regardless of which water filter unit you use (rear tank or side tank), Keurig water filter cartridges fit the bill.
An old water filter that is not replaced regularly will eventually ruin the quality of the coffee a coffee maker makes. So you don't forget when it's time to replace your used filter, set a water filter reminder on the circular dial on the filter handle. The dial is clearly visible when filling the tank with fresh water.
