Orange staining in tubs and sinks, plus a rotten egg smell, are two of the most common well water complaints — and often solved by the same piece of equipment.

Both are extremely common in groundwater because they come from naturally occurring minerals and bacteria in the soil and rock the water passes through. Dissolved iron oxidizes on contact with air, creating the orange-brown staining on fixtures, laundry, and in toilet tanks. Hydrogen sulfide gas, produced by sulfur-reducing bacteria, is what creates the classic rotten egg smell — often stronger from the hot water tap because heat accelerates the bacterial reaction inside the water heater.
Modern whole-house filter systems designed for iron and sulfur typically use an air injection or oxidation stage to convert dissolved iron and hydrogen sulfide into a filterable, solid form, followed by a filtration media bed (often catalytic carbon or a specialized oxidizing media) that captures the converted particles before they reach your plumbing. The better systems handle both contaminants in a single unit rather than requiring separate treatment stages.

Systems using air injection with a backwashing media bed are largely self-cleaning and need minimal maintenance beyond periodic media top-offs every several years, which is a major advantage over older approaches like chlorine injection systems that require ongoing chemical refills.
Iron and sulfur filtration doesn't address hardness (calcium/magnesium), which causes scale buildup and is a separate problem usually solved with a water softener. If you have both issues, most whole-house setups install the iron/sulfur filter first in line, followed by a softener downstream.
Orange/rust staining on fixtures and laundry points to iron; a rotten egg smell, especially from hot water, points to hydrogen sulfide. Many wells have both. A water test confirms exact concentrations.
No — dissolved iron and hydrogen sulfide gas pass right through standard sediment filters. They need an oxidation stage first to convert them into a filterable form.
No, iron/sulfur filtration and water softening address different minerals. If you have hard water in addition to iron/sulfur, you'll want both, typically with the iron/sulfur filter installed first.
