What's in the box

Size	Mineral tank	Media	Control valve
10"x54"	10" x 54"	sulfur-removal filter media (catalytic carbon blend)	Fleck 2510SXT air-injection valve
10"x44"	10" x 44"	sulfur-removal filter media (catalytic carbon blend)	Fleck 2510SXT air-injection valve
12"x52"	12" x 52"	sulfur-removal filter media (catalytic carbon blend)	Fleck 2510SXT air-injection valve
13"x54"	13" x 54"	sulfur-removal filter media (catalytic carbon blend)	Fleck 2510SXT air-injection valve

• Control valve: Fleck 2510SXT air-injection valve with built-in air injection.
• Bypass: 3/4" bypass valve (included).
• Mineral tank: black fiberglass-wrapped mineral tank with support bed and distributor.
• Media: sulfur-removal filter media (catalytic carbon blend), sized to the tank.
• Also included: 1" plumbing adapters, install and service manuals.
• Ships pre-built, ready to install, free in the US.

How it works

The valve draws a pocket of air into the top of the tank. Water passes through the air, which oxidizes iron, manganese and hydrogen sulfide into particles, and the media bed filters them out. Every day the valve backwashes the bed, sends the trapped particles to drain and refreshes the air pocket.

Media benefits

• Removes hydrogen sulfide: no rotten-egg smell
• Stops black staining on fixtures and silverware
• Daily automatic backwash keeps the bed clean
• Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

Eliminate rotten-egg sulfur odor from well water

That unmistakable rotten-egg smell is hydrogen sulfide gas dissolved in your well water. The AIO Sulfur Filter System drives it out with air-injection oxidation — a chemical-free method that converts the odor-causing gas into a filterable solid and captures it, so clean, odor-free water reaches every tap.

When you need it

If your hot water smells like rotten eggs, if the odor is strongest first thing in the morning or after the house has been quiet, or if guests notice a sulfur smell you have grown used to, dissolved hydrogen sulfide is the likely culprit. Beyond the unpleasant smell, sulfide is corrosive and can tarnish silverware and darken fixtures over time.

Why air injection is the right tool for sulfur

Hydrogen sulfide is stubborn: carbon filters load up quickly and softeners do not touch it. Air-injection oxidation is different. Water flows through a pocket of compressed air held at the top of the tank, where the dissolved sulfide is oxidized. The media bed beneath then filters out the resulting particles. Each backwash flushes them to drain and refreshes the air pocket, so performance stays consistent without ongoing chemical dosing.

Built for low-maintenance ownership

• No chemicals or feed pumps to monitor, refill, or calibrate.
• Single-tank design keeps the footprint small and installation straightforward.
• Automatic backwash renews the system on its own schedule.
• Whole-house coverage so the odor is gone at showers, sinks, and appliances alike.

Installation notes

Plumb the system into the main line where water enters the home, with a drain line for backwash and a nearby outlet for the control valve. Once set, it runs on its own — there is nothing to refill and nothing to dose.

Sulfur frequently travels with iron in well water, and this air-injection platform is well suited to both. Where hardness or low pH are also present, we recommend staging the treatment so each problem is handled in the right sequence. Share your water test and we will confirm the configuration, size it to your flow, and ship it free in the US with full manuals and expert support.

Get the right size

The amount of hydrogen sulfide in your water and the number of fixtures running at once determine the right capacity. Send us a recent water test and a sense of your busiest water use, and we will confirm the configuration, set the backwash frequency for your conditions, and back the system with knowledgeable support for the life of the unit.
