FREQUENTLY ASKED QUESTIONS

How can I tell when my mask filter is completely depleted?

For particulate filters, difficult breathing is the indicator that the filter pores are clogged. For gas filters, replace them immediately if you smell or taste chemicals inside the mask. For your safety, never rely on a visual inspection to determine the condition of the filter elements.

Can I use an FFP2 mask to protect against odors from paints and solvents?

No. Standard FFP2 respirators protect only against dust particles and aerosols. Protection from organic vapors such as paints and varnishes requires a mask with an activated carbon filter or a half-mask with specialized gas filters marked with code A. Stenso also offers combined solutions for such environments.

Does facial hair affect the effectiveness of respiratory protective equipment?

Yes, facial hair prevents the mask from sealing tightly against the skin. Even a minimal gap allows contaminated air to bypass the filter. To achieve the stated level of protection, the face must be clean-shaven in the sealing areas.
