@DrMariaNeira @mvankerkhove @gabbystern Brilliant @WHO guidance! Quick suggestion. You might update Annex 3 on #AirFilters before cascading because #EN779 and #EN1882 were replaced by #ISO16890:2017 eg MERV13 recommended equivalent is class ePM1 80% (ePM1 60% minimum). FYI @Camfil_UK sponsors our #IndoorAir campaign
