A complete whole-house air-injection filter. One price includes everything listed below.

What's in the box

• Control valve: Control Flow metered air-injection valve with built-in air injection.
• Bypass: bypass valve (included).
• Mineral tank: black fiberglass-wrapped mineral tank with support bed and distributor.
• Media: Katalox Light catalytic filter media, 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 iron, manganese and hydrogen sulfide (rotten-egg smell) in one tank
• Handles high flow rates in a compact tank
• Long media life
• Backwashes the trapped particles to drain automatically
• Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

Advanced Media, Efficient Operation

Katalox-Light® stands out for its low pressure loss, high flow and service rates, and high bed loading with less frequent backwashing. The media can run at flow rates up to 12 gpm per square foot and requires just 5 to 10 minutes of backwash at 5.5 gpm per square foot. Crucially, it needs no potassium permanganate or chlorine to stay regenerated, which simplifies ownership and reduces ongoing costs.

Air injection oxidation feeds the media bed, while Control Flow Technology meters regeneration to your actual water use for added efficiency. Installed at the point of entry, this Water Softener Plus system delivers comprehensive treatment for challenging well water across the whole home. It arrives nearly complete — add the adapters that match your connections — for a clean, capable, low-maintenance whole-house solution delivered conveniently by parcel.

For demanding well water, testing for iron, manganese, sulfur, and pH before setup helps confirm sizing and ensures the Katalox-Light media is matched to your conditions. Locate the unit on a level surface near the main line and a suitable drain, with clearance above the tank for valve service. With no potassium permanganate or chlorine to manage, ongoing care is minimal, and the high-loading media delivers strong, multi-contaminant performance over a long service life.

Whether you are upgrading aging equipment or treating a new well for the first time, this system from Water Softener Plus offers a proven, low-fuss path to cleaner water, backed by the trusted engineering behind every component in the package.
