unhg Sport Mask with Carbon N99 Filters - # 171

The mask is nicely made and comfortable to wear, and the replaceable N99 carbon filters said it can be continuous use up to 50 ~60 hrs +. It means one filter will last me over a month or even longer. A lot better than my N95 medical procedural mask only good for one day the most.
