Wonderful innovative product. I would call it Nanofilters. I have purchased this product for my mother who has to wear big mask all the time due to Kidney Transplant. Just wanna make one suggestion, launch it in skin colour make it look more transparent so that it is not visible because when you wear it present form many people start enquiring if nose has scar, injuries etc.
