Query: Brews Quick and Requires Little Maintenance

We've had this coffee maker for over a year now and it still works wonderfully! It brews 12 cups really fast. If it slows down, just brew 2 to 4 cups of white vinegar and you're back to quick brews. We do clean the coffee maker with vinegar once or twice a month. To be honest, we haven't replaced the filters like it says to, but it seems to be just fine. We brew about 8 cups of coffee once a day.
