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

The AIO 10" x 44" Sulfur Filter System in parcel-delivery configuration delivers chemical-free hydrogen sulfide removal in a package prepared for convenient shipment by parcel carrier. Built around a single-tank air injection design, this whole-house filter eliminates the rotten-egg smell of sulfur from well water using nothing more than oxygen and a smart, self-cleaning control valve, with no salt or chemicals to buy or handle.

Oxidation, Then Filtration

During normal service, the system holds an air pocket at the top of its mineral tank. Sulfur-bearing water rising through that pocket is oxidized, transforming dissolved hydrogen sulfide into particles that the media bed can capture. The Fleck 2510SXT control valve runs an automatic daily backwash that washes those particles to the drain and refreshes the air pocket, so the system keeps treating water continuously with nothing for the homeowner to monitor or replenish.

This compact 10" x 44" system suits smaller households dealing with sulfur odor that affects drinking, bathing, and laundry water alike. Installed on the main water line at the point of entry, it treats every tap in the house simultaneously. The parcel-ready packaging eases delivery and handling in many installation situations. Thanks to automatic daily regeneration and chemical-free operation, ongoing maintenance is minimal, making this a practical, set-and-forget solution for homeowners who are ready to be rid of sulfur-tainted well water for good.

For homes that can't easily receive freight shipments, the parcel-ready packaging makes this sulfur filter far more accessible, arriving via a standard carrier without special handling. Operation remains fully automatic and chemical-free once installed, with the trusted Fleck 2510SXT valve managing the daily backwash. Confirm your water's sulfur concentration to ensure the 10" x 44" size is appropriate, and you'll have a convenient, hands-off solution that clears rotten-egg odor from your well water and keeps it pleasant throughout your home. Over the long run, the chemical-free design spares you the cost and handling of sulfur-treatment chemicals entirely.
