Hi,
I received a catalog from Conservation Resources and they have a new
product line called Micro-Chamber (paper, boxes and folders)  that is
supposed to collect and hold atmospheric pollutants, protecting the
artifacts better than the "previous archival standards".

Does anyone know about this stuff?  Does it really work?  What happens
once the board becomes saturated with pollutants?

Thanks in advance for your help.
