Nelsen C-Series AIO Iron Filter System

The problem
Iron staining from well water causes rusty red or brown marks on sinks, fixtures, and laundry, creating unsightly surfaces that are difficult to clean. Over time, dissolved iron can clog pipes, reduce water flow, and damage appliances like water heaters and dishwashers.
These issues affect water quality, home aesthetics, and equipment lifespan, making it crucial to address iron contamination effectively and efficiently.
How it works — the air injection oxidation that fixes it
This system uses air injection oxidation to convert dissolved iron into solid particles by introducing controlled air pockets inside the media tank. These oxidized iron particles are then trapped by the iron-reduction media and flushed away during backwash cycles.
The Connected Series Air Draw Meter Control Valve allows independent programming of air-draw and backwash cycles. This lets you add extra air daily without triggering unnecessary backwashes, saving thousands of gallons of water annually. The valve also releases compressed air slowly before backwash to prevent plumbing damage caused by sudden pressure blasts.
What it handles
Built for Iron staining (well)
The Nelsen C-Series AIO Iron Filter System is specifically engineered to address iron staining issues common in residential well water supplies. Its compact size and advanced air injection oxidation make it ideal for smaller homes or properties with low to moderate iron concentrations.
Through Bluetooth connectivity and a user-friendly app, homeowners have unprecedented control over filtration performance and maintenance schedules. This system is uniquely suited to those seeking a chemical-free, water-conserving solution that simplifies water quality management while protecting plumbing and appliances from iron damage.
Built on a genuine Connected Series Air Draw Meter Control Valve valve — not a disposable clone
This system runs on a Connected Series Air Draw Meter Control Valve control valve — the industry-standard brain of the system. Its parts are stocked by water dealers nationwide and stay available for decades, so a worn seal or piston is a quick, low-cost rebuild — never a throwaway. For a Iron staining (well) where downtime is expensive, that serviceability is the whole point. We never build on unbranded clone heads that strand you when they fail.
Genuine, serviceable, warrantied — a system you keep for 15 years instead of replacing in four.
