Will whole house filters or reverse-osmosis filters work better?

A whole-home filter may not be effective because it does not treat water that flows through interior pipes, brass, and leaded-solder, which can contaminate the water with lead even after it has passed through a whole-home filter. Any water treatment filter used should be National Sanitation Foundation Standard 53 (NSF-53) certified to remove lead and should be located at the end of the plumbing right before the tap, so that all water that flows through home plumbing is treated. The certification label is typically displayed on the package and the filter.
