Carlton from Dallas, Tx writes

When using the Comfo Classic Respirator Mask, can one P100 Cartridge be used and the second port closed?

Answer:

Using only one P100 respirator cartridges with the Comfo Classic Respirator would allow entry of unfiltered air from the other side as there is no way to close it off. It would essentially defeat the purpose.
