A respiratory and eye protection device having at least one filter and at least one axial fan. The least one filter is configured to achieve an aerosolized particle contamination filtration efficiency of 50% or greater for particles having a size of about 0.3 μm and configured to achieve a vapor contamination filtration efficiency of 50% or greater for one or more of Novichok nerve agent (A232), thickened venomous nerve agent (TVX), sulfur mustard agent (HD), thickened sulfur mustard agent (THD), soman nerve agent (GD), and sarin nerve agent (GB). During the operation and monitoring of the respiratory and eye protection device, at least one fan is activated when concentrations of select aerosolized chemical, biological, radiological, and nuclear (CBRN) agents are detected.
