Finnish Nokia M61 V3 Gas Mask test

Test of the Finnish M61 V3 Gas Mask/Respirator made by Nokia.
The V3 M61 has a metal voice diaphragm built into a plastic housing that also holds the exhale valve, unlike the earlier masks which simply had a rubber exhale valve in it's place with a directional cover.

The voice diaphragm works fairly well but is a weak point of the mask, the voice diaphragm did not come with any O-rings so over time a leak is likely to happen, mine was easy to repair using an industrial adhesive but bear in mind that these masks may come with a faulty voice diaphragm if you are buying them as surplus and intending to use them.
