The problem

Hard water, iron, manganese, and chlorine contamination affect water quality in many homes across the US. These elements cause staining, unpleasant tastes and odors, and can damage plumbing and appliances over time.

Iron and manganese contribute to reddish-brown and black staining on sinks, fixtures, and laundry, while chlorine imparts a harsh taste and odor to your water.

Untreated, these contaminants reduce water enjoyment, interfere with cleaning, and lead to costly maintenance. The Nelsen AIO Katalox Filter addresses these problems efficiently in one complete system, ensuring your water is clean, clear, and healthy for everyday use.

How it works — the katalox media technology

To the whole system

The heart of the Nelsen AIO system is the premium Katalox Light media, a granular filtration material designed to remove iron, manganese, hydrogen sulfide, and chlorine through an oxidation and filtration process.

Water flows through the Katalox media where dissolved iron and manganese are oxidized and trapped within the filter bed. Simultaneously, chlorine and other oxidants are reduced, improving water taste and odor.

The system operates automatically, with backwashing and regeneration cycles that flush out accumulated contaminants to maintain consistent performance. Regular maintenance typically involves periodic media replacement after years of use, depending on water quality and usage.
