FM filter mask

Use : all kinds of dust, mist,  welding fume (organic solvents, removal of ozone-smell : carbon filter)

Materials : the silicon tissue + MB filter + polycarbonate body

In exhalation, valve that connected filter closes and the air is exhausted into the lower exhaust valve. The humid air mixed in exhalation is not reached the filter, so the life cycle of filter is maintained for a long time relatively.

In inhalation filtered air through the filter pass through the inhalation valve.

This is more economic  than  disposable filter mask because of the silicon block contaminated air by stuck on face, strong polycarbonate body, inhale and exhale valve doubled durability of filter by isolation moisture in exhale breathing

Great in protection against dust performance.
