How do you know if an S10 gas mask filter is expired or not?
Hi, I virtuous got my S10 gas mask today and before I use the filter I need to know: on the foil sealed filter, it says it was manufactured and sealed in 06/06/90 and impregnated in 01/08/89
Does anyone understand if the filter has expired or not? and the foil wrapping over it has an approx. 1 inch long cut in it, does this use the filter at all?
Thanks, Lincoln.
Never, ever, conviction a perforated seal. It's there for a reason and obviously it's integrity has been compromised.
There are replacement filters nearby on line, even eBay.
