Question about Stöckli Filter

If you make sure that the filter does not get wet, i.e. do not fill the container too much before emptying it, it can last a good three months. At the beginning I made the mistake of washing the filter (with the lid), then the filter quickly becomes thin and no longer holds in the opening.

It depends on how many you order (1 to 4 pieces). If you order more, they are a bit cheaper. But one piece still costs more than 6 francs, which is quite expensive.
