Metal filters are normally made of stainless steel or aluminum. The main difference between metal filter and paper one is that the metal coffee filter has larger pores. So it doesn’t block as much of the natural oils or tiny coffee grounds. But it doesn’t mean that it is bad. Vice versa, many people believe that coffee brewed with a metal filter is full-bodied, rich, and tasty. For instance, certain flavors only appear when there are oils in the coffee, which give a sweetness that paper filters remove.
Due to the fact that metal filters are reusable, you’ll need to clean them after every usage. Actually, they’re quite easy to clean, especially if you use stainless steel. It also makes them very environmentally friendly.
One of the brightest and most well-known examples of metal filters is traditional Vietnamese coffee filter – phin. Coffee made this way is rich, strong and very aromatic. Here
