Do You Need A Water Filter For Keurig?

A charcoal filter will help remove chlorine, calcium and other impurities from your water. Without one, these minerals can build up in your machine more quickly. This can impact both the brewing systems process and the taste of your cups of coffee.

Also, if you don’t use and regularly replace a filter, then your Keurig will require descaling more often than the recommended 3-6 month intervals. Since descaling can be a time-consuming process, I think you are better off buying the Keurig filter and changing it at the suggested time.

If you are adding filtered water to your machine, then a filter may not be needed. However, using one is really important if you are using tap water.

If you know your tap water is “hard” (meaning high in minerals), then a filter will be important for helping you maintain the life of your coffee machine. If you are not sure about the level of minerals in your water, then you can always get a low-cost water testing kit.

How Often To Install A New Keurig Water Filter?

Water filters should be replaced every two months or 60 tank refills. It’s best to set a reminder for 60 days once you swapped yours. However, if you use your machine multiple times a day, you may want to consider a more frequent replacement schedule.

Since the it helps remove impurities, changing the filter at the suggested time or more often is the best thing you can do to keep your Keurig coffee tasting as good as it did on day one. From time to time you may also see blinking light error messages on your Keurig that could require changing the filter.

What Happens If You Don’t Replace The Water Filter?

Your machine will still brew coffee without one. However, over time the lack of one can lead to the buildup of minerals in your machine. As a result, you’ll need to descale your machine more often than owners who do use water filters. This process can be time intensive, but if not done regularly, the minerals left in the brewer can damage the machine. This may cause leaks and other issues with water pumping, speed of brewing and amount of coffee brewed.
