Press the mask with nose clamp around your nose well.
6. Wash mouth mask in a pan with water
You can put the mask in a pan with hot water and boil it out, which saves a lot of water and energy compared to washing in the washing machine. Cook the mask for at least 15 minutes so that all bacteria are killed. Drain the water and pick up the mouthpiece from the pan with clean, washed hands or latex gloves. Dry the mouth cap on the clothesline. Are the face masks dry? Then take them off the clothesline with clean hands or latex gloves and put them in a tightly sealable plastic bag, such as a ziplock bag. Be careful when you remove the mask from the pan. The mask will be very hot.
6.1 Washing in the washing machine
Put the mask in a washing bag and wash with a short wash program at 60 degrees or the other indicated temperature in the mask. Centrifuge at low speed. Take the mouthpiece out of the washing machine with washed hands and hang it on a clothesline to dry.
