corvettegirl, thanks for the guidance. I watched the quick tutorial. I wonder what the filter is embedded with. It appears to be S for sulfur. Also it says research is in early stage. I am familiar with how long research requires, and I hope GLW gets lucky with the time factor.
(I searched for Mercury control and these were the vendors listed.)
