![]() ![]() To produce a modern gas mask filter takes unprecedented skill and expertise. Like most CBRN filters on the market today, take protection to an even higher level, with safeguards against things like organic substances with low boiling points, including mercury, COx, NOx and radioactive metal iodide. ![]() Modern gas mask filters, on the other hand, are truly a technological marvel. The history of gas masks and how gas mask filters became practically universal is something we've already covered in our Gas Mask Buyer's Guide, so we won't delve into that here. We’ve assembled all the research you need to make an informed decision and give your family the protection they might need. So, we’re going to look at everything you need to know about gas mask filters: from their practical function and specifications to the logistics of storing them and, should the need arise, putting them to potentially life-saving use. That’s a mistake that can cost you time and money…or something even more important. These complicated factors are often overlooked by new and even experienced buyers. Creating a working gas mask filter takes specialized knowledge of how to impregnate carbon with a key balance of metal salts and then treating the blend with chemicals to pass strict testing requirements. The craftsmanship of their construction matters just as much as the science behind their effectiveness. have been in the process of viewing and sorting the recovered material.A single filter can protect you from all of the contamination from a nuclear meltdown for forty full hours, while another filter could help you safely navigate the smoky environment of a house fire to reach safety.īut each gas mask filter has its limitations…Įach filter has a shelf life, classification, specs and price. “The amount of material found in the wall is overwhelming,” the city archive said on Facebook on Monday. Archivists were able to find more information about Wiedey in the city records, including the fact that she married in 1913 and had two children, but were unable to track down much about her apparently unsuccessful suitor.Īrchivists have recovered 12 boxes of materials from the site and are in the process of examining them.

It also benefited from donations of assets and goods seized from Jewish groups and individuals. The organization ran relief operations and kindergartens. Many contemporary accounts describe this kind of rapid disposal of sensitive materials-but it’s unusual to find an intact trove.Īccording to Blank, the find may help historians learn more about the NSV and its role in the Nazi regime. “That must have happened very hectically,” he says. ![]() ![]() Ralf Blank, manager of the Hagen city archive, tells Frankfurter Allgemeine that NSV members probably hid the documents and other materials in the wall when Allied troops marched into the city in April 1945. Yurtseven and his aunt say the family had no idea of this history when they purchased the property in the 1960s. Investigating further, he found a cache of World War II–era artifacts, including a portrait of Adolf Hitler, a revolver, gas masks, Nazi Party badges, brass knuckles, letters and documents.Īs it turns out, the building housed the local headquarters of the National Socialist People’s Welfare organization (NSV) during the Nazi era. When Yurtseven pulled out a rotten piece of plasterboard, he spotted a foot-wide space behind the wall containing a newspaper dated to 1945, writes Insider’s Sophia Ankel. “I didn’t think it would turn into such a huge discovery.” “I got goosebumps,” Sebastian Yurtseven told local media, as quoted by the Times. Last month, a history teacher cleaning his aunt’s house in Hagen, Germany, after severe flooding discovered a trove of Nazi artifacts hidden behind a wall, reports David Crossland for the London Times. ![]()
