Keurig K-Express Water Filter Guide

Does the Keurig K-Express Have a Water Filter?

Yes, the Keurig K-Express coffee brewer, as well as the K-Express Essentials model, has a spot for a water filter located in the machine’s rear water reservoir. The K Express uses charcoal water filter cartridges measuring roughly 2 inches long by 1.125 inches tall. The filter is placed inside a BPA-free, clear plastic filter handle (typically sold separately from the brewer), which is then placed inside the water tank located on the back of the machine.

Which Filter Attachment Does the Keurig K Express Use?

The K-Express brewer uses the Tall Handle Water Filter Holder. This water filter handle attachment is about 8 inches tall and is designed to install inside your Keurig coffee machine’s water reservoir tank.

How Do I Install the Keurig K-Express Water Filter?

To install the water filter on your Keurig K-Express brewer, simply twist the clear plastic filter housing until it comes loose from the bottom of the water reservoir. Remove the old charcoal water filter from the housing by unsnapping the bottom filter holder. Insert a new, fresh water filter cartridge and snap the filter holder back on so that the filter is securely in place. Finally, align the bottom of the filter housing with the indentations on the bottom of your water tank and twist into place.

Does the Keurig K-Express Need a Water Filter?

Everyone’s water quality is different. It is commonly recommended to use a water filter to improve the quality and taste of your beverages, as well as to help protect your brewer against scale buildup from minerals in your water. You might especially want to use a water filter if you notice unpleasant tastes, such as from chlorine or other minerals.

How Often Should I Replace the Water Filter on my K-Express or K-Express Essentials Brewer?

You should change your water filter after brewing approximately 1000 fluid ounces through your coffee maker. This comes out to about 125 eight ounce cups of coffee, or about every 2 months.
