I don't think it would be enough absorbant to keep you from getting screwed - the dwell time would not be sufficient. This is just an indicator - kinda like the CO alarm in your house - get the hell out if it rings until you figure out what's up!
Gotcha on the LED/phototransistor now. Interesting.
As far as whether it could be enough sorb, I guestimate a pound may well fit in the inhale hose. Dwell time may not be the greatest but the presumption is that the main scrubber was doing at least part of its job and most of the scrubbing would occur there.
