Assuming you would like instructions on how to open a coffee filter machine:
First, find the power switch and make sure the machine is turned off. Next, locate the water tank and unscrew the cap. Fill the tank with fresh, cold water. Once the tank is full, screw the cap back on tightly.
Now it's time to insert filters into the filter holder. Make sure the rubber gasket is in place at the bottom of the holder. Then fit the cone-shaped filter inside, being careful not to tear it. Wetting the filter beforehand will help it adhere to the holder.
After inserting a filter, add your desired amount of ground coffee to the top compartment of the machine. Be sure not to pack down or overfill as this can negatively affect brewing quality. Close up this compartment by snapping it into place (it should click).
Now you're ready to brew! Place a mug under the spout and press down on button corresponding to your preferred brew size (small, medium or large). The machine will take care of everything else - heating water to optimal temperature and then slowly dripping it over your grounds for rich flavor extraction without bitterness.
