Excuse me, 3M 120 1 gas mask, can it prevent formaldehyde? Can this mask be equipped with a formaldehyde filter box separately?

Hello! I'm happy to answer your question.

120 1 is mainly used for the protection of some organic vapors, but it is not suitable for the protection of formaldehyde, a special organic gas. It is suggested to use 3M 6005 filter box with 6200 or 7502 mask for respiratory protection of formaldehyde to obtain more targeted and lasting protection.

I hope the above reply will satisfy you! If you have any questions, please ask the enterprise questions.
