With that goal in mind, our F LINE masks were developed with a unique filtering system. When exercising, we inhale a larger amount of oxygen; F LINE masks balance air filtration and the amount of oxygen inhaled, meaning the mask allows air to quickly pass through the filter to be inhaled as clean oxygen. What makes this balance possible is our exclusive MICRONET filter, specially developed by NAROO MASK.
MICRONET is made from a special fibre that blocks 99% of dust particles ranging from 1.7 to 2.6 um in size. 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.
