This is an extremely simplified item. Functionally, we have improved the traditional coffee dripper which requires supporting shelf and more space, so that the volume of the new system will now de fully applied. The better sealed dripper system could prevent the falling of flies into the container and remain clean. With the better sealed dripper, you don't have to worry about any uninvited guests-flies, dusts, that accidentally end up in your coffee. It just occupies 10 or 13 cm in diameter. After the dripping, the bottom bottle can go into the refrigerator with cover.
