I've spent a good amount of time messing around with HP breathing air compressors (I have my own for SCUBA diving) and can volunteer these 2 links as explaining the final filtration process really well.</div>

<div dir="ltr">But in a nutshell, if you're going to be breathing it, especially if you have to bail out at depth, I wouldn't be trusting my life to tampons... The activated carbon and molecular sieve are pretty cheap, and much more manly :).</div>
<div dir="ltr">Using an old hydraulic cylinder also has high potential for adding odours to your air that no filtration will get rid of - there is some good stuff about that in some the Airspeedpress books on diy oxygen systems.</div>

<div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12pt;">
<div>Gamma has an onboard hp compressor now. Since I may need to breathe the air from the main hp tanks in case of smoke or passing gas :-) I need to filter the air. I am making a filter housing from a hydraulic cylinder and filling it with tampons. I read that tampons work for this. Is that true? I hate buying tampons, !!</div>
