They have a multilingual site, but for some reason, it is separated from the Polish version: https://dafi.info/en/
And I can’t find the … whatever it is called to inject CO2 in English … there.
I can also recommend Grohe Blue Fizz. Thats from the German Brand Grohe which I have been using for a while and its pretty good. I got them based on Stiftung Warentest results, a german foundation for testing products. Apparently they got bought by a Japanese brand though 2014. I think Brita is also German and they have a similar solution.
