Hello, and I am pleased to help, use of my answers are for educational purposes only.

Dr. Wilson :

What type of gas mask filter?

Dr. Wilson :

Is the filter in a sealed package?

JACUSTOMER-pyy2mu36- :

I am getting a Russian gas mask that comes with the filters for that particular mask (PBF).

JACUSTOMER-pyy2mu36- :

The filters are suppose to new and unused

JACUSTOMER-pyy2mu36- :

*to be

Dr. Wilson :

So, this is for particulate, not really gas

JACUSTOMER-pyy2mu36- :

??? Particuate?

Dr. Wilson :

Usually masks for Gaseous fumes do have an expiration date - but if in a sealed container then they should be good until the expiration date on the package.

Dr. Wilson :

Particulate - meaning saw dust, or dust of any type

JACUSTOMER-pyy2mu36- :

LOL

Dr. Wilson :

And, for particulate - there is no expiration

Dr. Wilson :

What are you using the gas mask for

JACUSTOMER-pyy2mu36- :

No, it is for gases like, smoke and tear gas.

JACUSTOMER-pyy2mu36- :

I would want to use it in case of a fire

Dr. Wilson :

Oh, you should be fine with that - this is more particulate protection then

JACUSTOMER-pyy2mu36- :

To give myself an extra chance of making it out of the house, if I were in that situation

Dr. Wilson :

And, should filter out most if not all the problem gas / particles

Dr. Wilson :

Yes, PERFECT.

Dr. Wilson :

I hope this helps, if you have additional questions, please do ask, and PLEASE click on ACCEPT, as this would be appreciated for my time, thank you.

JACUSTOMER-pyy2mu36- :

So it should work fine on smoke from a house fire AND should be fine if not past expiry date listed on the package?

Dr. Wilson :

Yes, it should for what you need

Dr. Wilson :

Since you will NOT be working with it and just being used for a short period of time

Dr. Wilson :

such as getting out of the house

JACUSTOMER-pyy2mu36- :

What about opened and installed filters? Will they last or does the "shelf life" drop afterwards?

Dr. Wilson :

For your short purpose, just keep the filters in a closed container or even in a dresser drawer or night stand draw for emergency use only - and this will work for your purposes.

JACUSTOMER-pyy2mu36- :

Ok then. Thank you

Dr. Wilson :

Your welcome, please click on ACCEPT as this would be appreciated.
