Arsenic intrusion in your household water isn’t just a hidden nuisance — it’s a silent threat that chips away at your family’s health and your home’s integrity. Stains on fixtures, metallic tastes, and unexplained skin irritation are often the first warning signs, but the consequences extend far deeper. Prolonged exposure can lead to serious health concerns, from chronic fatigue to increased risk of cancer, while corrosive water may gradually damage plumbing and appliances.

The system that fixes it

The C-Series Arsenic System is engineered specifically to tackle the unique challenges posed by arsenic contamination. At its core is the C-Series air-injection control valve, a genuine, serviceable brand valve designed for precise regulation and longevity. This innovative valve uses air injection to maintain optimal oxidation conditions, ensuring the arsenic is effectively converted and captured before it reaches your taps. The system’s backbone is an air-injection oxidizing tank, built to enhance the oxidation process that transforms harmful arsenic species. Inside this robust tank lies the iron-based arsenic-selective media, a powerful filter medium that doesn’t just trap Arsenic V but also actively oxidizes and binds the more elusive Arsenic III form. This specialized combination guarantees thorough arsenic removal for safer, cleaner water.

With the C-Series Arsenic System installed, your household water becomes a source of comfort and safety, shielding your home and loved ones from arsenic’s hidden harms.

How the media works

The iron-based arsenic-selective media inside the system is specialized to tackle arsenic’s tricky chemistry. Arsenic exists primarily in two forms: Arsenic III, which is more difficult to remove, and Arsenic V. This media functions by oxidizing Arsenic III into Arsenic V, then binding both forms securely. The iron content in the media acts as a magnet for arsenic particles, turning them from dissolved toxins into solid compounds trapped within the media. This oxidation and binding process ensures that arsenic is effectively removed from your water rather than simply filtered out temporarily, providing consistent, long-lasting purity.

Common questions

Q? How does this system handle the different types of arsenic in my water?
A The iron-based media both oxidizes the more elusive Arsenic III and captures Arsenic V, ensuring complete removal of arsenic in all its forms.

Q? Why is the C-Series air-injection control valve important?
A This valve maintains proper oxidation by injecting air at precise intervals, which is critical for converting and binding arsenic for effective filtration, plus it’s serviceable and reliable over the long term.

Q? How do I know what size system I need?
A Use the number of bathrooms in your home as a guide—the system capacity matches water usage patterns to deliver consistent arsenic removal without over or under-sizing.
