Well water

I'm looking for suggestions on filters for my rodi unit. I have softened water going in my rodi that is high in sulfur.

Tap the water before the softener. It will have less salt for the the RO to remove.
You can try an extra carbon filter before the RO to help with your sulfur.

Not sure the best remove the sulfur, but there are some filters that are suppose to remove iron and sulfur. I would use the softened water to feed the rodi unit. It is easier on the unit to remove any residual sodium versus trying to remove calcium (hard water), prolonging life of the filter.

I have well. I have a whole house carbon unit, then goes to softener, then to RO.

I have the same exact setup that your running. I did a icp test on my tank and it showed very high sulfur levels. I thought with all my filtration that it would not be present.
