Their claims concerning the product seem to pan out. It looks like
an excellent product. We investigated this product when it was being
marketed for the first time a few years back. I also share your
concerns about saturation. And the cost is quite troubling. A
scientist affiliated with our department said why not continue
purchasing the same type of board as before and safely slip a disc
of activated charcoal which could be replaced later? Or pursue
filtration at a larger level, such as in conjunction with the HVAC
system. Another minor quibble some have is that microchamber is a
corrugated board (which sometimes provides a good hiding place for
insects to lay their eggs).
