Here is a gorgeous coffee maker that helps you produce acid free coffee at home. You just have to put water and ice in the top jar to get started. The valve in the center regulates the dripping water, and you end up with great coffee in the carafe at the bottom of the tower. A permanent ceramic filter is included in this device.
The coffee maker holds 32 oz and takes about 3 hours to prepare your coffee. But you get a unique flavor that regular coffee does not offer. Sets you back under $275 at this time.
