MicroChamber products

Does any one know anything about the MicroChamber products by
Conservation Resources? I just received their catalog.  They claim
that it absorbs off-gassing, dust and pollutants keeping them from
artifacts.  Does the stuff really work? What happens when the box or
paper is saturated?  In your opinion is it really worth the extra
money, which is almost double the price of their regular materials.
