The rating of the ffp2 masks by Stiftung Warentest needs repair.
Stiftung Warentest is a foundation established in 1964 by the German federal parliament with the aim of helping consumers by providing impartial and objective information based on the results of comparative investigations of goods and services.
The organization buys products anonymously from retailers, and make covert use of services, carries out tests in independent labs that use scientific methods and follow their specifications and give verdicts ranging from „very good“ to „unsatisfactory“, based solely on objective results. The findings are published free of adverts in their magazines „test“ and „Finanztest“, and online at www.test.de.
A lot of time has passed since the 1960s and conditions have changed. For consumers, many more products and providers are relevant today than they were in the 1960s, as these are easy to find on the Internet. This makes it difficult for an organization “Stiftung Warentest” to keep track of all relevant products.
An example of this is the test of FFP2 masks that was published at the end of February. The test organization set up by the German Bundestag ignores precisely those masks that were the first to be tested by TÜV Rheinland from German production. If you are looking for the test results for the masks from the STOLFIG.SHOP, you will not find what you are looking for.
