How is a FFP3 face mask built
Filtering half mask X 310 SV of the class FFP3 is built of filter material and auxiliary accessories such as headbands , exhalation valve or holders for fastening the tapes . Air inhaled from the environment passes through filter material where it is cleaned . The exhaled air is expelled to the outside through the exhalation valve located in the cup and the face part of the half mask. The canopy of the half-mask should fit tightly to the face during use.
Characteristics of the X310 filtering half mask:
- multi-layer filter material : polypropylene
- nose clip for formatting the half-mask around the nose;
- exhalation valve plastic;
- head tapes made of braided rubber threads;
- fastening of the headband made of plastic;
- an inner liner to improve tightness i comfort of use .
FFP3 is a RD type mask:
- R - reusable
- D - a half mask with this marking can be used in a dusty room (such a mask has passed the dolomite dust clogging test)

How long can face masks be used?
Protective half masks can be used in one work shift, that is 8 hours . By this time they fulfill their protective properties. Protective masks FFP1 < / a>, FFP2 a>, FFP3 a > are designed to work in dusty conditions. In case we use these protective masks as protection against viruses and we are not working in dust, the case is otherwise. Studies have been carried out, which show that only after 10 days such masks lose their properties. Then on day 11 protective mask FFP3 lost its properties by only 1.4% .
