    Hi all, I made a filter for homemade gas mask:
    The connector for the filter and the mask (will make one in future) is made out of 2 plastic bottle caps glued, screwed and taped together:

    The bottle I've used is 0.33l from energy drink:

    The main filter is made out of char cloth (activated charcoal) with cotton from both sides around it, front and back (or top and bottom, however you wanna call it):

    [​IMG]SAM_1134 by ihatebottleopeners, on Flickr
    And finished it with insulating tape for no air leakage.

    Final thoughts: I haven't tried it yet (I'll try later in a room full of cigarette smoke :)), BUT I've tried on clean air, and the tiny charcoal particles are going in my throat because the cotton layer isn't stopping them. The point is that you (or I in this case) need to find a compromise: if the cotton 'walls' are too thick, they won't (probably) let charcoal particles go into my throat BUT will make the inhaling a lot harder and impossible to breathe for more than 3-4 minutes, also will make your lungs tired. More updates coming in future ;).
    P.S. If anyone have experience with this (homemade) stuff I'd like to know, any tips & tricks will be appreciated.

    I've learned from my mistake and put bigger pieces of char cloth, I wasn't crushing them this time and works far better, it even has better air flow because I put thinner piece of cotton on the upper part (the one closer to the face).

    Try cutting up one of those fabric particle respirators, not the preformed ones but the foldable ones and putting it on each side of the char.

    Thanks for the tip! I think they are a lot bigger than the bottle size, but my scissors will help me for sure :).

    Anyways, here's the final (or maybe?) product:

    I maybe look like a pharaoh with that long 'beard' :).

    It's a bit longer that I imagined at first, I can't lean my head downwards a lot, and will upgrade with rubber bands for extra insurance (later, as always :)).

    P.S. Don't mind me, I'm just killing some time experimenting and improving my skills using only hand tools and imagination :).

    One of the main characters users an improvised mask exactly like yours. Looks functional when in a pinch!

    Is this just for smoke? I see this as being alternative to a regular mask. I wonder if it would work for other substances as well.

    I think that the smoke is one of the hardest things to filter with a gas mask, so I must admit that I was smelling cigar smoke while I was testing it. I haven't tested it yet with paint, gas(oline), tear gas etc.

    You may also consider that the plastic edges are not properly sealing against your face and there may be some intrusion there. You're stubble may also have some impact of the efficacy of the seal You may notice that firefighters never have beards, because it interferes with their masks sealing properly.

    Try using some rubber inner tube to seal it around you face. That should work better and is easier to find in a :censored: scenario
