Can you use Keurig without water filter?

It is recommended that you use a Keurig with a water filter. It is there to eliminate any bad taste in the water. In addition, it removes any chlorine and dirt present in the water. However, water filters are an optional accessory, and you can use your Keurig without one.

You should change it every two months or after every forty gallons of use. But if you want to calculate how often you need to change your filter efficiently, you can do that too.

Simply, forty gallons is about 5120 ounces, and a cup of coffee is about 16 ounces, so if you drink just one cup of coffee every day, then it will take you about 320 days or about ten months to wear out the filter. Likewise, drinking two cups of coffee daily will last your filter five months.

And if you are an avid coffee drinker and drink six cups of coffee daily, it will take 1.7 months to wear out your filter.

Do I need to descale my Keurig if I use bottled water?

The mineral content of the water affects how often you need to descale your Keurig machine. Mineral deposits or scale may build up on your brewer and hinder the performance of the machine. It is recommended to use bottled water with your Keurig.

Frequently Asked Questions:

1#. Can your Keurig make you sick?

Like every kitchen appliance, coffee makers can be full of germs like bacteria and mold if they are not properly cleaned. Hot water is not enough to decontaminate all bacteria and mold, so a Keurig may likely build up enough of these germs to make you sick.

Dirty coffee makers are very common. One study found that coffee makers are one of the top ten dirtiest appliances in an average kitchen. So you better make sure to clean your Keurig machine every once in a while if you do not want to get sick.

2#. Why should you not use distilled water in a Keurig?

Keurig is equipped to handle many types of water. The sensors installed in the Keurig machines can detect the amount of minerals in your water and make your beverage accordingly for the best brew.

But if you try and use distilled water with your Keurig machine, the machine will show you an error.

As the sensors will not detect any mineral (As there are none in distilled water), the machine will assume there’s an error with the sensors and display an error message. Therefore, commonly using bottled water is recommended.
