For the most extreme safety compliance environments with maintaining comfort, the Moldex AirWave 4700 N100 Respirator is the gold standard. Foam cushioning and an exclusive SmartStrap custom fitting solution not only produces a better fit, but ensures greater compliance. Moldex's Dura-Mesh shell further ensures longer use, thanks to greater heat and humidity resistance and durability. Use in environments where an OSHA substance specific standard applies (lead, cadmium, arsenic, MDA) as well as pharmaceutical manufacturing, conventional and nuclear power generation, welding, cutting and metal pouring.
