Do All Keurigs Have a Water Filter? (find and replace it!)

Water filters are the most essential thing especially if you use tap water for brewing coffee. These charcoal filters can effectively remove chlorine and other debris from water only if the tap water quality in your vicinity is not too bad.

I personally use tap water for brewing coffee with Keurig, but it’s only recommended if the tap water quality is good and drinkable. Otherwise, use bottled water or filtered water.

But Do All Keurigs have a Water filter?

No, all Keurig models don’t have water filters. Most of the Keurig models have a place for water filters in their Water tanks but you have to buy water filters separately. There are some models, like K mini, mini plus, and Rivo, that don’t have a place for water filters. These machines are very compact, with a water reservoir capacity of only one cup, so technically, they can’t accommodate water filters.

Keep reading to find out if your Keurig machine is compatible with the water filter or not, and how and when you should change your Keurig’s water filter.

Which Keurig Models have a Water filter kit

You need to purchase the water filter kit separately with the Keurig machine and install it in the water reservoir.

The Keurig filters are located in the water tank of the machine and based on the model there are three different types of water filter kits.

Tall Handle water filter Kit: This kit is for the Keurig models that have water tanks taller than eight inches. These kits typically fit the models with the side water reservoir.

Keurig K classic water filter kit: This water filter kit is only compatible with K classic models and has a bulkier design. You have to check the serial number of your K classic model before purchasing the filter handle if it starts with “4” (44, 45, 48) you need a K classic water filter, if it starts with “55” you need a tall handle water filter.

How to change Keurig Water filter

To ensure that you brew a perfect cup of coffee every time and to maintain the longevity of your Keurig machine, you must clean the machine, descale it, and replace the water filters regularly. Otherwise, you may have issues like leaks in the machine, or the machine not pumping water properly.

How to change Keurig Water filter

Here’s a step-by-step guide on how to replace or remove the charcoal water filter of your Keurig machine.

  1. Before installing the new water filter in the machine, the filters need to be soaked and absorb water. So place it in a bowl full of water for 5-10 minutes. Meanwhile, you can remove the old water.
  2. Detach the water reservoir from your machine if it’s removable or simply remove the top if it’s not.
  3. Now grasp the water filter holder firmly with your hand and pull it out by giving a sharp tug.
  4. Remove the clip that holds the charcoal filter and discard the spent filter.
  5. After the new filter has soaked for 5-10 minutes, rinse it with water properly.
  6. Also clean and rinse the water filter handle properly, especially the bottom part, as there will be a lot of debris accumulated there.
  7. Insert the new filter in the filter handle with its rounded top facing up and reinstall the clip.
  8. Now rotate the dial at the top of the filter handle to the month you should change the water filter next. Ideally, the water filter should be changed after 2 months. So, if it’s January (1st month) rotate the dial to March (3rd month) and it will act as a reminder.
  9. Finally, place the water filter handle in the water reservoir and push it down firmly to lock it in place.

How often to change Keurig Water Filter

How often you should change the water filter mainly depends on the quality of water you are using to brew and how much you use your coffee maker.

Keurig recommends to change the water filter once every two months or after 60 tank refills whichever comes first.

Also, some Keurig water filter handles have a dial that allows you to set a reminder to change the filter on time.

Keurig water filters cartridges are charcoal-based filters that work effectively to remove chlorine and other debris from water when they are new but with time their filtering ability goes down and they become completely useless after they become saturated. That’s why it’s very important to change it on time.


Do you need a Water Filter in Keurig?

What’s the Best water for Keurig

It’s always a best practice to use filtered or bottled in Keurig. As well as preparing the most flavorful cup of coffee, filtered water has the perfect amount of minerals, typically less than 100 ppm, which leads to less scaling inside the machine and a perfect cup of coffee.

I personally use filtered tap water in my Keurig and it works really fine. It contains the right amount of minerals to make my coffee more flavorful and not too much that can cause damage to the machine.
