You gotta wear a mask anytime you’re out. If you will like a more environmental and cost saving option, you will like to consider this washable face mask. Our mask is treated with SILVERPLUS® technology Due to the triple effect mechanism of SILVERPLUS® many odour-causing bacteria cannot adapt to the effect of silver ions. The antimicrobial effect of the natural element silver is exclusively based on free silver ions. Due to a triple effect mechanism, silver ions with a positive charge have bacteriostatic effects. Mask up, people!
