Does a Coffee Maker Sanitize Water?

It is a common misconception that coffee makers sanitize water. In fact, most coffee makers do not have a mechanism in place to sanitize water. While boiling water will kill most harmful bacteria, it will not remove all contaminants from water.

Furthermore, coffee makers typically do not reach the boiling temperature necessary to effectively sanitize water. As such, it is important to use filtered or distilled water in your coffee maker to ensure the safest and best tasting cup of coffee.

Does Coffee Kill E Coli?

No, coffee does not kill E. coli. However, boiling water is effective at killing the bacteria.

Does a Keurig Get Hot Enough to Kill Bacteria?

Most Keurig machines heat water to between 197 and 204 degrees Fahrenheit. At those temperatures, any bacteria present in the water would be killed instantly. However, it’s important to note that the water reservoir in a Keurig machine is a potential breeding ground for bacteria if it’s not cleaned regularly.

So, while the hot water produced by a Keurig machine is capable of killing bacteria, it’s possible for bacteria to contaminate the water before it’s even brewed.
