Invisible yet insidious, arsenic contamination in your water silently attacks your family’s health and property. Skin lesions, numbness, and fatigue are just the beginning, as prolonged exposure can lead to severe organ damage and increased cancer risk. Beyond personal suffering, arsenic corrodes plumbing and appliances, jeopardizing your home’s integrity and inflating maintenance costs. Without a targeted defense, arsenic quietly erodes your quality of life.

The system that fixes it

Introducing the Pentek Arsenic System, a precision-engineered solution designed exclusively to eradicate arsenic from your home's water supply. At the heart of this system lies the Pentek-series air-injection control valve, a sophisticated head valve that actively manages the oxidation and regeneration cycles vital for media longevity and peak performance. Unlike generic valves, this genuine Pentek valve is fully serviceable and crafted to ensure reliability over years of use, meaning you avoid costly replacements and downtime. The system’s core consists of an air-injection oxidizing tank that fosters optimal oxygen levels, enhancing the oxidation of arsenic compounds. Inside, iron-based arsenic-selective media chemically converts both Arsenic III and Arsenic V forms into insoluble compounds, effectively binding them and preventing harmful arsenic from passing through your pipes.

How the media works

The iron-based arsenic-selective media inside the Pentek Arsenic System is specially designed to neutralize arsenic in its two most toxic forms: Arsenic III (arsenite) and Arsenic V (arsenate). This media triggers an oxidation reaction, transforming soluble arsenic compounds into solid particles. These particles then bond tightly to the media’s surface, effectively removing them from your water supply. This chemical process ensures that arsenic does not pass through the system, preventing it from entering your taps. The media’s selectivity ensures it targets arsenic specifically, leaving essential minerals in your water untouched, so you receive safe, natural-tasting water without harmful contaminants.

Common questions

Q? How often do I need to replace the media to maintain arsenic removal?

A The media’s lifespan depends on your water’s arsenic concentration and usage, but thanks to the system’s efficient air-injection valve and oxidizing tank, the media typically lasts until the grain capacity is exhausted, minimizing frequent replacements.

Q? Will this system remove other contaminants besides arsenic?

A The Pentek Arsenic System is specifically designed to target both Arsenic III and Arsenic V. While it may reduce some related metals, it is not intended as a general-purpose filtration system for other contaminants.

Q? Can I service the control valve myself if something goes wrong?

A Absolutely. The genuine Pentek-series air-injection control valve is fully serviceable, allowing you or a professional to perform maintenance and repairs easily, ensuring uninterrupted arsenic removal.
