Despite being dentist and inches away from the patient's mouth and nose, I was never able to get N-95 masks for the members of my dental team and myself. They seemed to be reserved for front line workers even though we were seeing emergency patients at the time. I was so excited to be able to offer even better coverage than an N-95 for the staff and myself with the Z-Link Respirators. I do not have to worry about procuring N-95 masks again. When I placed a picture of the staff in their respirators I had dental team members from other offices saying they wish their dentists would do the same! It's American made and I don't have to worry if I can get a replacement part from China! The folks at X1 Safety are quick to answer any questions and give you tutorials. Great investment and great experience. I highly recommend the company and the product.
