Are these the same gas mask or are they different? To me they look the same...Is there a difference between these two gas masks?
I'm a vet, and I say that the only difference is price, but if you buy the mask that is 19.99, I suggest investing in a brand new filter just to be safe. The filter is only an additional $6.Is there a difference between these two gas masks?
I believe they are.
They both say they are Israeli Gas masks so they are the same.
I think they are the same ones


but email them both and ask a few questions first





good luck
