You’ve already done hours of research on the best Keurig coffee maker, and you’re ready to pull the trigger and purchase one. But wait, there’s one more thing to consider – filters. 

Keurig has two different types of filters – water and coffee. 

But wait again, you thought the draw of a Keurig was that you didn’t need to buy hundreds of coffee filters. And you don’t, but there is an option to use Keurig’s reusable coffee filter. More on that later.

The second filter is a water filter. 

The general consensus is that filtered tap water is the best type of water to use in your Keurig. Personally, the tap water where I live is not the best, and I don’t have the best system to filter minerals out of my tap water. For this reason, I use bottled water to brew coffee in my Keurig.

If you don’t have the best tap water and don’t want to use bottled water like I do, you might want a Keurig water filter directly in your machine.

Do All Keurigs Have Water Filters

Does every Keurig machine have a water filter?

Technically, no. Keurig brewing systems do not come out of the box with a water filter. Instead, there is a place for a water filter in most coffee brewer models’ removable water reservoirs. The water filters are held in place by one of three water filter handles. The handle size depends on which Keurig machine you have in your kitchen.

Tall Handle Water Filter Starter Kit

  • One water filter handle 
  • Two filter cartridges

The Tall Handle Water Filter Kit is for Keurig machines with a water reservoir taller than eight inches.

The K Classic Water Filter is only compatible with machines made before the 2.0 line. Additionally, it is bulkier and more obvious than the other two options. 

Keurig Water Filter Cartridges

The Keurig Water Filter Cartridges are charcoal-based filters. These charcoal filters work to remove chlorine, calcium, and other impurities from your water to give you the best tasting cup of coffee possible. 

How often do I have to change my water filter?

You should change replaceable water filters every two months to ensure they keep working to the best of their ability. Only the cartridge needs to be changed, not the water filter handle. 

How do I change my Keurig water filter?

Before you replace your water filter, soak the new filter cartridge in water for five minutes, then rinse the cartridge under cold water for 60 seconds. Next, take the water filter assembly out of the water reservoir and remove the old filter cartridge from the bottom.

To open the water filter handle, remove the lower filter holder from the upper filter holder. Replace the old cartridge with the new one, and snap the filter handle back together. Place the water filter handle back in the water reservoir and push firmly to lock the filter handle into place. 

Does Keurig offer a reusable water filter?

No, Keurig does not have a reusable water filter option. The charcoal water filter cartridges are designed to be thrown away after two months. While the cartridges are not reusable, the water filter handle is. 

Always include the water filter handle in your regular Keurig machine cleaning routine. The water filter handle can be washed with dish soap and warm water. 

Keurig Coffee Filters

I know the draw of a Keurig machine is not having to deal with coffee grounds and coffee filters. So, why am I bringing it up now? 

Keurig offers the option to use your own coffee grounds with a specific filter. 

Do you need a coffee filter for your Keurig?

No. If you are using a K-Cup pod with your Keurig, you do not need to worry about using a coffee filter. If you would like to use your own ground coffee beans, you can do so with the My K-Cup Universal Reusable Coffee Filter (sold separately). 

To use the K-Cup Reusable Coffee Filter, fill the filter to the max line with your favorite coffee grounds. Place the K-Cup Filter into your Keurig as if it were a typical K-Cup and brew as usual. Before you know it, you’ll have a freshly brewed cup of coffee.

What happens if you don’t change a Keurig water filter?

If you do not change the water filter on your Keurig after two months, the filter will lose its ability to filter your water. Over time, the dirty filter may change the taste of your cup of coffee.
