Benefits of a Sulfur Filter System

While sulfur in your water doesn’t cause health issues, it can leave your water with a foul odor and taste, often linked to that of rotten eggs. Hydrogen sulfide and its distinctive smell can be drastically reduced with chlorine injection treatment. If left untreated, dissolved hydrogen sulfide can corrode metals, which can cause blackening of your silverware and discoloring of copper and brass utensils. With the Pentair Sulfur Filter System, you can transform the quality of your well water by equipping your home with an efficient sulfur solution. Save your silverware, plumbing, and appliances from sulfur stains while enjoying refreshing, great-tasting water from every tap in your home.

  • Convenient pressure release button for air pressure maintenance

How it works

Sulfur Filter System

Chlorine Contact

Chlorine mixes with your sulfur-contaminated water to reduce nuisance organisms.


The mixing time for disinfection depends on chlorine concentration, water temperature, pH level, and the amount of organic matter present. Our specialized retention tank mixes the chlorine faster than standard retention tanks for optimal chlorine contact.
