No matter which system you choose, remember: filters need love. If you ignore the cartridge, sulfate will eventually find its way back like an ex who doesn’t get the hint. Mark your calendar for monthly checks.
One more pro tip: if your water smells fine cold but stinks when heated (like in a shower), you might have a water heater issue, not a sulfate issue. The anode rod in your heater can breed sulfur bacteria. Swap that rod for an aluminum one—it’s a $30 fix that kills the smell instantly.
