Introduction

Typical masks made from 2 sheets of felts or 2 layers of cotton materials cannot block radiation, foul odors, or toxic gas.
AIRREX K-1 MASK TO PREVENT RADIATION is a specially made emergency mask composed of 5 layers of filters and embedded with activated carbon used for silicon gel processing and gas masks.  The mask is especially recommended if a fire breaks out or for other dangerous situations when an emergency mask is absolutely necessary. Also, this mask is an anion creator.
