Overview

Envioneer makes water-purification filters and advanced materials used in rechargeable batteries, listed on KOSDAQ, South Korea's tech-focused small-cap exchange.

Its filters use a positively charged nonwoven fabric to trap contaminants and are supplied to both household and industrial water-treatment applications. The company also produces a thermal-runaway prevention material for rechargeable batteries, a nonwoven composite designed to reduce heat-related hazards. Water-purification filters account for the majority of its revenue, making that product line the dominant driver of the business.
