This is a set of parts (coarse grind mesh filter, filter case, and paper filters) for the Panasonic fully automatic coffee maker "NC-A57". By using the "coarse grind" filter, you can grind the beans to your preference. The main unit automatically grinds the beans and brews the coffee, and the mill is also automatically cleaned. The "boiling water purification" function removes over 90% of chlorine. It is equipped with a "decaf beans" course specifically for decaffeinated beans, allowing you to brew rich coffee.
