Big-Capacity, Chemical-Free

The system treats hydrogen sulfide without any salt or chemical feed. A pocket of air maintained in the tank oxidizes dissolved sulfur into a filterable form that the deep media bed captures and holds. Control Flow Technology meters regeneration to actual household water use, so the unit backwashes only when needed — flushing trapped sulfur to drain and refreshing the air cushion. There are no feed pumps or chemicals to replenish at any point.

The large 14-inch diameter and 65-inch height provide the highest service flow in the residential sulfur range, ideal for large or multi-bath homes and wells with heavy rotten-egg odor. Installed at the point of entry, it delivers fresh water to every tap and shower in the home. Supplied by Water Softener Plus, this configuration arrives nearly complete; add the plumbing adapters that fit your supply lines for a clean install and efficient, low-maintenance performance over the years.

For the cleanest result, position the filter on a level base with room above the tank for valve service, near both the main line and a drain. Some homeowners with combined issues add this sulfur filter ahead of a water softener, treating odor first and hardness second. With no chemicals to handle and no feed pumps to prime, the unit settles into a quiet, reliable routine that keeps showers and drinking water free of that telltale rotten-egg smell.

As part of the Water Softener Plus catalog of well-water treatment equipment, this unit is chosen and assembled to deliver consistent, real-world results, helping you protect your plumbing investment while enjoying noticeably better water at every fixture in the house.
