I want to tell you about a recent research about Filters with Asbestos. A dutch professor did some test with the filters wich you can buy together with the Russian gas masks. These filters that come with contains Asbestos fibers, we know that asbestos is dangerous for us. Here in holland you can still buy them very cheap but don’t use them. Maybe there will nothing happens but the idea is not cool when you know that you are breathing a dangerous cancerous substance.
The professor is telling about that the filters contain carbon grains where the asbestos fibers are between. Because this is loose in the filter it is likely that you breathe directly.

Be careful when you buy this kind of filters.
