For a long-term solution, install an oxidative filter. These guys use manganese greensand or a catalytic carbon media to turn hydrogen sulfide into harmless sulfur particles. It sounds fancy because it is—but it works like a charm. You’ll go from “ew, what’s that smell?” to “wait, water can taste like this?” in a week.
If you’re on a budget, try a point-of-use carbon filter for your kitchen sink. It won’t fix the whole house, but it’ll save your morning coffee. A good filter costs about as much as two months of bottled water, so consider it an investment in your nostrils’ dignity.
