I have a GVS mask steriliser got on Amazon. Very neat and possibly meant for travel. Works by USB. You close lid and press a button. The mask is bathes in UVC for 10 mins.
RT @astaines: @NChildersMEP They can also be cleaned and reused, if needed, but don't use soap or alcohol. Air drying works surprisingly well. You can also steam in a microwave, carefully, they get very hot!
