MICRONET is made of special fibre that blocks 99% of dust particles ranging from 1.7 to 2.6 um in size.

This is 40 times smaller than the diameter of a human hair. It is incorporated into the fabric of the mask and can be washed along with the mask, without having its efficiency reduced or affected.

The F LINE masks and MICRONET™ filter by NAROO MASK set a new high standard in filtering masks.

Unique design, advanced air filtering and washable features make NAROO MASK an industry leader.
