The Moldex 4800 Airwave respirator was created with both comfort and savings in mind. The Airwave features a patented technology that allows it to expand and contract with your breath for more airflow. Patented FlexFit design allows the respirator to move with the wearer’s mouth movements for a comfortable fit that worker’s won’t mind wearing. The Airwave’s Dura-Mesh shell keeps the filter cleaner longer and holds its shape even in hot and humid environments. The result is a longer lasting, more comfortable respirator so you can save on costs!
