Does anyone know where to find distilled water in Reykjavik for my CPAP machine and what I should ask for? Different countries call it different names and sometimes it's located with other water, but I've found it with laundry supplies and auto supplies in different countries.
I would try a pharmacy. The Icelanders call it eimað vatn.
Allison, unless you need it for humidification, you don't need to use distilled water. I have not used distilled water in my cpap for over a year. Saves me a lot of time cleaning and refilling the reservoir.
Pretty much every source I have checked says that using tap water is fine for short periods. Soaking the reservoir in vinegar water when you return home will clear any mineral buildup.
