"Hello Carlos,As a painting contractor for 20 years I came across you innovative ESPIRE respirator mask while looking for a mask that allows our faces to be seen during the COVID-19 GLOBAL PANDEMIC for May self and employees. Yours is the only design I have found anywhere! Your respirator would be most valuable to ALL FIRST RESPONDERS now and in the days to come: EMT’s, NURSES, DOCTORS, POLICE, FIREFIGHTERS, SUPPORT STAFF, and ALL ESSENTIAL WORKERS. The ease of replacing the filter without removing the mask is of particular value. If 3M or Honeywell or any other manufacturers is not banging down your door to bring this to market I can’t imagine why. We need this yesterday!Look forward to seeing it soon. Feel free to update us, we are all on the edge of our seat waiting for a reply!God speed,Marc from California USA"
