The way most home automatic coffee makers work is to boil a very small bit of water in a tube....water above that bubble is then lifted up into the brew basket....repeat. So in each bubble lift there is steam and warm water. The overall water temp is generally around 150-190 degrees depending on the maker.

This will probably kill lots of stuff, but it is really not going to be the same as boiling a pot of water for 1 minute.

Commercial brewers (most of them) have a large tank of water that is held at 190-200 degrees....this would probably be much more effective than the typical home automatic makers.

Old percolators eventually boil the whole brew....generally for quite a long time and should be quite effective.
