When your water carries harmful algal toxins — cyanotoxins — it’s more than just an unpleasant nuisance. These invisible poisons can trigger skin irritations, respiratory distress, and even gastrointestinal illnesses for you and your family. Worse still, they quietly infiltrate your pipes, appliances, and fixtures, accelerating wear and jeopardizing your entire home’s water quality. Ignoring cyanotoxins means risking costly repairs and compromised health with every shower and sip.

How the media works

The heart of the Pentek Algal Toxins System is its specialized media: activated carbon with oxidation support. Activated carbon is renowned for its ability to trap contaminants on its porous surface. In this system, it adsorbs cyanotoxins — the harmful chemicals produced by algae — effectively removing them from your water. The oxidation support within the media complements this process by breaking down stubborn, heavily concentrated algal blooms chemically. This two-pronged approach ensures that even severe cyanotoxin conditions are tackled at the source, leaving your water clean, safe, and pleasant for daily use.
