      Don’t use the good filters though. Filters don’t usually clog with particulate, it’s usually all the water vapor from your breath. They get moldy.

      The cheapest filters also restrict the most airflow. So for best results buy the crappiest filters that will fit in the mask. Leave them out in the open in a cool dry place to outgas and then they should last a month or so for training.
