Coffee is usually brewed a little below boiling, and in any case blasting water to 212°F and then serving it doesn't always kill all the bacteria- you need to boil it for a couple minutes. I forget how long though.

If bacteria are a problem where you libe you can simply boil your water for a few minutes, take it off the heat for it to cool down to the temp you want, and then use it to brew coffee.

Right, but if the office has a coffeemaker and no stove, you can't do that.

The office probably has a water cooler though right? You could probably fill the coffee maker with that.

You can get an LED bacteria pen. Those will kill most of the bacteria in the water before using it to make coffee.

Those aren't LED. It's an unshielded UV lamp.
