A few years ago I was diagnosed with sleep apnea, and as a result, I travel with a CPAP machine, which uses distilled water in the humidifier portion of its program. It takes about a cup to fill the reservoir, and that lasts several days. I buy distilled water at the local grocery store; it costs about eighty-nine cents for a gallon.
Remember that. Eighty-nine cents for a gallon.
The first time I traveled to Ireland with my CPAP (2012, I think), I asked Gerry to pick up some distilled water for me. They don’t carry it at the grocers there; you have to go to “the chemist’s” (Americans would call this the pharmacy) to purchase it.
Half a gallon (actually, two liters) of distilled water cost eight euro. Eight euro! That’s sixteen times what it costs in the States! (But wait—there’s more. When I returned in 2013, the cost had more than doubled, to seventeen euro. That’s what it cost in 2015 too.)
WHY? This is the question. Why is it hard to find (you have to order it and wait for it to come in; it’s not kept on hand to sell to the public), and why in the world does it cost so much? My mother, back in the day, kept distilled water on hand to put in the iron, for steaming (this is no longer necessary, by the way). It has never been expensive nor difficult to find in the States.
But it sure is in Ireland. I’ve spent a lot of time searching for answers—which I have mostly found on various message boards. No travel website on either side of the Atlantic has addressed it, as best I can tell. So here’s what I’ve gleaned about the availability of distilled water in Ireland:
- Pharmacy: The chemist will be able to get it for you. Be prepared to wait a couple days, and pay through the nose.
- Boil and cool: Water in Ireland is very hard, so you don’t want to put it in your CPAP as is. However, you can boil it and cool it. Takes more time, of course, and when you’re traveling it isn’t particularly convenient, but it’s a solution. Most hotel rooms are equipped with electric kettles.
- Health food store: I found this chain of health food stores in Galway selling distilled water in one-liter bottles. But a check online of several shops in Dublin yielded no such convenience, though it may just be they don’t get enough call for distilled water to add it to their online product database.
- Car-parts store: Because distilled (or deionized) water is used in batteries. I have yet to walk into a car-parts store in Ireland to find out. I’d call ahead.
- Babies: I’ve also read to try the baby section of supermarkets (for humidifiers and such, I guess). Again, I have yet to try this, and I’m not going to count on it until I can. But at €17 for a half gallon, who could afford to run a humidifier in baby’s room, eh?
Finally, a reminder that deionized water is not the same as distilled water; check with your CPAP manufacturer before you put it in your machine.
Bottom line—if you’re traveling to Ireland and know you will need distilled water when you get there, do some advance planning. If you’re visiting friends or relatives, they can help. Otherwise, call your hotel’s concierge or your B&B and ask them to track some down for you (and remember to tip the concierge well when you arrive).
