I have used an M04 gas mask and found all the issues mentioned previously. I did quite a few alterations.
The mounting points for the straps are weak and break so I removed them and drilled holes and bolted the straps to the mask.
The lenses themselves are pretty sturdy but the way they clip to the mask isn't so I epoxied them in place.
The fan kept cutting out and it was only just strong enough to prevent fogging so I removed the internal structure of the filter and inserted a CPU cooling fan. This runs off a NiMH battery in a shirt pocket. This was a bit of overkill, but definitely no fogging issue now. There is a bit of a noise issue
The mask just would not sit right so I added padding to the top of the mask. This also means that when worn with a hood or helmet air is blown over the top of your head due to the fan upgrade.
