Description

This durable model has a long working time.
The 3-dimensional mesh structure of ultra-fine fibers and electrostatic technology allows for easy breathing and efficient dust collection.
The 3M dust proof mask fits well to the shape of your face, so it reduces air leakage when breathing and increases the efficiency of the actual particle collection.
