Filter Mask

A filter mask is a fine cloth mesh, usually of silk or cotton, that covers your mouth and nose. Cords or straps fasten the cloth around the back of your head to provide a good seal. A filter mask grants a +2 bonus on saves against gas-based effects. It negates the effects of suffocation from dust and sand, as well as the effects of supernatural or magic dust (such as slumber sand ) for up to 4 hours. After this time, the mesh is clogged with grit and can no longer allow air to pass through freely. A clogged filter mask requires thorough laundering before it can be reused, but most travelers simply replace it with fresh fabric.
