Sulfur Guard filters provide a turnkey remedy for handling foul-smelling "rotten egg" water. Unlike other systems that use multiple treatment stages and are expensive, cumbersome and complex to maintain, there’s not much to do with a Kinetico Sulfur Guard™ filter but enjoy your water.
Dual tanks accommodate higher flow rates needed in multi-person and larger homes.
Moving water is the power source, not electricity, so operation is simple and reliable. There are no timers or computers to set, adjust, repair or replace.
If your tap water smells like rotten eggs, there's a good chance the problem is hydrogen sulfide gas. This colorless, corrosive gas often causes the unpleasant “rotten egg” or sulfur smell in well water. Hydrogen sulfide forms naturally when organic material, like decaying plants, breaks down in the absence of oxygen. It’s especially common in groundwater sourced from wells drilled in areas with shale, sandstone, coal deposits, or near oil fields.
Another common source of hydrogen sulfide in water is sulfur-reducing bacteria. These bacteria thrive in low-oxygen environments, especially in hot water heaters or plumbing systems. They convert naturally occurring sulfates in water into hydrogen sulfide gas, releasing that strong sulfur smell into your home’s water supply. This can affect both the taste and odor of drinking water and cooking water, leaving food and beverages with a metallic or rotten flavor.
High levels of hydrogen sulfide can even leave an unpleasant smell on hair, skin, and clothing after washing. It may also speed up corrosion in metal parts inside dishwashers, washing machines, water heaters, and other appliances—leading to early wear and potential breakdowns. If your well water smells bad or you notice a strong sulfur odor when running the hot water, it’s important to have your water tested.
This non-electric water filtration system is built for reliability and simplicity. Unlike traditional filters that rely on timers or computers, our whole-home filtration system uses the power of moving water to operate—no programming, adjustments, or electronics required. This means fewer parts to break, less maintenance, and long-lasting performance you can trust.
Thanks to its metered, demand-based design, the system only regenerates when needed. This smart approach eliminates waste, prevents odor breakthrough, and ensures you always have a fresh, clean supply of soft water. The twin-tank system allows for continuous, around-the-clock soft water—even during regeneration.
A Kinetico whole-home system uses integral stages to provide clean, clear, conditioned water throughout your home.
