ATTENTION: the MLHU has a new recommendation for Masking
Non-medical masks or face coverings ideally should be made of at least 3 layers:
-2 layers should be tightly woven material fabric (e.g. cotton or linen)
-middle layer should be a filter-type fabric (e.g. non-woven polypropylene fabric, disposable filter, folded paper towel)
If your mask does not comply with this, disposible 3-ply masks are available at the Security Desk or Welcome Centre.
