14. Particulate Respirator
If the person next to you is coughing up a lung or the plane begins to veer wildly off course, it can be very beneficial to put a particulate respirator on.
These masks will help filter out the contaminants that are in the air, and this can protect you from airborne illnesses and other irritants. These respirators might also save your life if a natural disaster causes widespread fires or the release of harmful chemicals. Always remember that steering clear of the fire itself may not be enough to keep you safe from smoke inhalation and other related issues
