Coming soon - we'll take you through all the viable ways of serilising disposable masks for reuse we can find, once we start seeing approval from Public Health Authorities for doing this.
We're looking into it (as I'm sure others are), and the 'Anatomy of masks' video contains a lot of notes about things to consider. But it'll be in the hands of your country's Public Health Authority as to whether this will be permitted. We'll keep you updated if we hear more.
If you can't get disposable masks, consider buying respirators, which are intended for reuse, and for which a sterilisation procedure has been developed and tested.
