More odor control methods

So how's about some good old fashioned baking soda?
Some dryer tube catching the out-put air, from your box or room, into a box with:
2 simple air filters, baking soda in between. You must layer it so air can actually pass through. Some baking soda then card board tape it in between your filters and you are all set.

a carbon scrubber, ya thats it
