Mine Safety Appliance Company Dustfoe G-1000 Pre-Filter

Our industrial size Pre-filter is NOS (new old stock) in the original unopened box. It was made in the USA by Mine Safety Appliance, the leader in industrial safety products. This filter was originally purchased by the United States Government for use in the unfinished WPPS Nuclear Power Plant. Due to budget overruns, the project was abandoned and the materials were sold as surplus. It was another HUGE waste of taxpayer money, but you can still personally benefit from this case of government waste.
