I will need distilled water for my CPAP machine while we are in Germany. Not certain what is called there and in what type of store I would purchase a bottle.
According to the Net, the term is 'Distilliertes Wasser', and it can be purchased in large supermarkets and gas stations.
You can get this at most drugstores like Rossmans, DM, etc. Pharmacies should also have this as well as grocery stores. Probably not in Aldi or Lidl though.
I've typically found it in the baby section of a drugstore (DM or Rossmans). Sometimes it's packaged in a carton rather than a bottle.
