Volatile Organic Compounds (VOCs)
What it is
VOCs are a broad group of carbon-based chemicals - some from industrial or agricultural runoff, some forming as disinfection byproducts - that can reach drinking water.
Why it matters
The EPA regulates a number of specific VOCs with individual maximum contaminant levels. Because 'VOCs' is a category, certification is tied to specific compounds rather than the label as a whole.
What removes it
A filter certified to NSF/ANSI 53 for the specific VOCs of concern (often measured via a chloroform surrogate).
Reference: EPA National Primary Drinking Water Regulations (VOCs).

FAQ
- Does carbon filtration remove VOCs?
- Quality activated carbon reduces many VOCs, but certification to NSF/ANSI 53 confirms it for the specific compounds tested.
