Finnish Gas Mask question

Post by BrightShiningLIe » Sat May 03, 2014 10:38 pm

I just purchased a Finnish gas mask. Now I know this isn't the best mask but I wanted to get something that I could afford now for practice purposes and some protection from tear gas or pepper spray. I live near a concert hall and things could get complicated. Also smoke and some localized, minor chemical spill could cause problems.
Now with that out of the way I also want to emphasis I don't have prior military experience so I can't fall back on that.
I put the mask on, tightened it up breathed in and the mask tightened against my face. I then breathed out. Everything all right on that front. Then I tried to breath in and no joy. I tried several times and wasn't able to bring in air. Finally I breathed out very hard and breathed in with force. I was then able to bring in some air. The only way I can breath is by breathing in hard enough to cause the mask to tighten up and collapse onto my face. Do gas masks normally require so much force to breath, am I doing something wrong? Any answers would be very helpful.

Stupid question, you do have a filter on it, right?

I tried both with and without the filter. It would seem these masks have one way valves but I don't know if they are the issue or not.

If it's serviceable, it should only work with a filter on it. It will be a little difficult to use, but not as hard as you're making it sound. It should have a good solid seal though. Could just be a bad mask or filter.

I like the Finnish model because the left side filter allows you to easily sight a rifle while wearing it :clap:

Let me try again because I'm not sure I'm being wholly clear. I mean no offense but I know so little about gas masks its actually kind of difficult to describe the situation.
When I breath in I have to breath in strong enough the the cheeks of the gas mask get pulled in. It takes that much force to pull in a good breath. Yes I can do it without the filter in. Why would the filter be needed since it's more or less a hole in the mask to let air in through the filter mount?
By the way thanks a lot for your prompt responses I didn't expect such quick feedback.

There should be some air flow through the filter.

There's usually a seal at the air intake vent, a plastic plug you're supposed to remove.
With the sealed filter attached, there should be no air coming into the mask at all, which is a good thing.

Did you take the seal off?

That little white plug on the filter.

Is there a date on the filter?

The m15 or the old-ass civy model?

It should prevent flow coming in without a filter to prevent contamination when changing filters. I don't know anything about the Finns, only the M40s, but it does require more effort than breathing without the mask. May I ask which model you have?

It certainly sounds like something's not allowing proper flow, but I'm just an end user. Maybe soemoen with more CBRN experience will step up.

I took of the plastic plug which - based on later research may have been a bad idea. With the filter attached I could breath at all. Rather disconcerting so I took the plastic plug off.
The filter says SUOD 61 T at the top. Below that is Hilli: KRH ASC 12 X 30.
Immedialtly below the SUOD is stamped 270.
The only other number I see is 85. To me that suggest the filter dates back in 1985. Cold war stocks indeed.
As for the mask itself the only number I see is 1 which is at the top of the forehead. Does that narrow it down at all?

Shake the filter gently. Is there any noise?

I checked again. No noise at all so no particulates have broken lose. That I had heard about in the past and should have mentioned that. Sorry my bad.

Isn't there a separate outlet for breathing out?

You're gonna have to order replacement filters now, since you broke the seals.

Last I heard, people were ordering the gas mask/bag and pitching the mask, bag was used for misc EDC stuff.

There's youtubes about it.
