I have one by cuisanart I use at work. I like Starbucks® Sumatra, and use spring water to brew coffee. It’s amazing what a difference the water makes! I also regularly sanitize the carafe, which is stainless steel, with a warm water-baking soda mixture. You basically dump some baking soda into the clean pot, then add just enough water to make a thick paste, and push the paste along the walls of the pot to absorb the residue that collects. Easy and cheap, it is also a green way to keep your coffee pot clean.
