How long do filters last?

There is no clear answer to this question as too many factors can influence the life of filters, including, but not limited to, welding process, type of materials, condition of materials, run times, position of extraction hood relative to the arc, welder skill level, ambient air movement, humidity, and more. Filter status indicators are included on all portable, mobile, and downdraft tables to help the operator determine the filter lives for their unique welding conditions.
