Sean suggested a charcoal filter and it has been on my mind. I think it is a great idea. I was thinking about putting the charcoal filter on the scrubber intake because my rebreather scrubber is a sealed can. The other scrubber would need to have the filter on the discharge end. </div><div>Has anyone done this.</div><div>This has come to mind after Scott brought up the smoke issue. Is there a reason I should not put one at the intake of my rebreather scrubber. It should help with toxic smoke since it is the scrubber I can breath through manually.</div><div>Hank</div></div></body></html>
