There's nothing like the aroma of freshly brewed coffee. With the AdHoc Mr. Brew Coffee Maker, it's possible to make freshly brewed coffee that wakes up your senses without any additional filter paper. MR. Brew Pour-Over Coffee Maker Simply scoop in freshly ground coffee into the double-walled stainless steel filter, place the filter in the correct position using the magnetic height adjustment, position your favorite cup underneath it, and pour the hot water over the coffee grounds. The Mr. Brew filter is made from double-walled, flavor-neutral stainless steel. The fine micro-pores allow the full flavor of the coffee to seep through while capturing the coffee grounds.
