A good filter will get most of the objectionable things including sulfur.
I've run three different filters on the line into the coach, with the first standard ten inch carbon block filter first to get most of the sediment, chlorine, lead, and other nasties. I still found the last in line ceramic filter got a whole lot of sulfur, in it down toward Florida and in La.
There are now several submicron ceramic filters, on the net, though not cheap. Use the whole house filter from Lowes is usually sufficient but then a sub micron ceramic/carbon block last filter gets just about everything. Too small a filter and it will load up fast, in some places like Michigan with dirt and bypass the muddy water into the coach.
Home Depot has an almost identical GE filter housing to the Whirlpool 10 inch cannister, but is not transparent, with a remote that lets you know when it is time to change the filter. Great, if you are staying somewhere for a while. Hardest problem is fittings. The junk from Lowes and Home Depot is plated too look like brass, zinc or threads aren't good or out of round etc. Had to go to a plumbing supply. The hose connector/adapter was junk, so I had to eliminate it and use a good quick connector set.
