¿When should we use a disposable mask?
When the oxygen concentration is higher than 17%.
I know to which pollutant I am exposed.
The contaminant is olfactively detectable.

Activated carbon
ACTIVATED
C CARBON Models with activated carbon eliminate odors and discomfort caused by low levels of orga-
nic vapors that are found next to the particles.

Dolomite clogging
D DOLOMITE The optional Dolomite obstruction test is intended to check the maintenance of the filtering
CLOGGING
capacity when a certain amount of dolomite is passed through the filter, a very fine powder
that clogs the pores and saturates the filtering surface. Masks that include the letter "D" are
suitable for use against this type of powder. Ideal for exposure to wood dust.

Exhalation valve
The models with valve provide greater comfort, reduce moisture condensation inside, pre-
vent fogging of glasses, offer a feeling of less resistance and help inspire-expire easily.

Pre-formed
When the user breathes in air, the valve closes the diaphragm; when it exhales, it opens.
The valve releases air down to prevent condensation in the glasses. If the worker wears
protective glasses, this helps to prevent them from being fogged up.

Foldable: Horizontal or Vertical
