No - Crosstex pouches should only be used, EtO, Steam, gamma irradiation, E-Beam sterilization technologies - NOT chemical vapor or dry heat.
Yes, all of the Crosstex face masks are latex free.
There is an inside and outside to masks. All Crosstex masks have a non-dyed (white) inside layer to be worn next to the skin, with the earloops attached to the outer layer. Mask ties or earloops can be adjusted, twisted and angled to pull mask edges tightly to the face contour to prevent leakage.
The pressure across the mask material. It is inversely related to breathability, but with greater mask efficiency, you may lose some breathability. The lower the Delta-P, the greater the breathability.
BFE = Bacterial Filtration Efficiency; the % of bacteria filtered out at a pore size of 1-5 micron.
PFE = Particle Filtration Efficiency; the % of particles filtered out at a pore size of 0.1 micron.
There are many reasons for redness and rashes on the face. We recommend that anyone with a sensitivity to face masks, use the Crosstex Ultra Sensitive Face Mask or the Crosstex Isofluid Plus Pure, both masks are designed specifically for sensitive skin.
