These face masks are 100% cotton as well as double layered to mitigate germs and bacteria. Although they do help reduce the spread of this virus and other illnesses, these are NOT meant to replace the N95 face masks, nor are we claiming they will prevent this virus transmission with 100% efficacy. These are non-surgical face masks designed due to a severe shortage of masks in our country. AvèDon is working to do our part in helping reduce the spread of this virus by implementing these face masks. We are committed to flattening the curve of this virus by any means necessary. Proceeds will go towards producing mass quantities of these face masks to use for donation to the hospitals, nursing homes, and essential store employees! Thank you all in advance for your support!
