Trihalomethanes (THM) removal from drinking water

Do you test any of your water filters for removal of THMs? This is of particular concern for our town water supply. I'd like a drip system but have been unable to find one that tests for THMs.
THMs are reduced by an activated carbon filter. They are not as easily removed as say chlorine, for example because they require more contact time between the water and the carbon media. It is that particular reason why drip or gravity filtration is the BEST at THM removal. We have one test result, however, that shows that even with a pressure filter, the Doulton ceramic filter elements will filter these organic chemicals out to a very high degree. Please see:
