Made from food safe, microwavable silicone. Can also be used as drinking cup during outdoor activities.

Volume: 225 ml
Dimensions folded: Diameter 80 mm / Height 20 mm
Dimensions unfolded: Diameter top 80 mm / Diameter bottom 50 mm / Height 80 mm
Sold as: 1 cup (please make a color choice)

How do I use the disinfection cup?

Please place your MeLuna into the disinfection cup and fill it with water. The MeLuna has to float. The correct wattage settings depend on your microwave model. The water must be boiling for the disinfection to be effective. If in doubt, please consult your microwave manual. Most customers use medium power level / wattage for 3 - 5 minutes. The cup's lid must not be completely sealed during the microwave process! otherwise the steam produced by the boiling water cannot escape.

The disinfection cup is now very hot because of the heating process. Please take appropriate safety measures (pot cloth, oven mittens) for your hands and be very careful when removing the disinfection cup from the microwave. Preferably please let the cup and its contents cool down inside the microwave to be on the safe side.


PLEASE NOTE: This cup may contain metal components that are SAFE for use in the microwave. This has been tested extensively by the manufacturer in Germany.

Please see the info provided by Miele here:

May metal go in the microwave?
Of course. After all, the entire interior of a microwave is made of metal - and that does not get hot during operation or causes the microwave oven to explode. However, you should not put thin metallic foils (eg aluminum foil) or cutlery and crockery with metallic decorations (including the gold ornaments on and in plates) in the microwave, as they can even melt in the worst case, but at least the much-cited arcs arise which can damage the material and in the worst case even the microwave oven.

Nevertheless you should be careful with pots and pans, because you can not be sure how massive the material is or which other metals were used - especially aluminum is absolutely taboo! If you are not sure, it is better to refill the food before placing it in a safe container. These are marked by a corresponding logo and the note "microwave-suitable".
