So initial reports for the efficacy of upcoming Norwex masks were 0.4 microns at 60%. THE NEW EFFICACY RESULTS ARE AMAZING!!! The Norwex masks will be able to filter out 0.1 microns at 80%!!!! That really blows my mind. Again, I will let you know when they are available and I will put up a link so you can order directly off my website and I never see your credit card information.
