This product is fine.<br />I gave it 3 stars because it just covers the nose & mouth area (smaller than expected). Further, after receiving my order, I learned from friends that research does not support the use of these filters in face masks other than to protect from odors. Also, there are no conclusive studies at this time on whether carbon filters can be harmful to your lungs when used in face masks & directly inhaled for any period of time. The fault is mine; I need to do more research before purchasing products. However, hoping this review will help others avoid my mistake, and encourage people to do their own research & come to their own conclusions before ordering.
Rating: 3 stars
