Using tap water instead of distilled?

Postby jrod » Wed Sep 15, 2010 2:05 pm

I am going to be leaving for Europe soon and I'm concerned with being able to find distilled water for use in my humidifier.

Will using regular tap water damage my machine or cause ill effects?

Lots of debate on these forums about that one!

As for the machine...it will harm over the long range...just need to clean more thoroughly with short term use of tap water. As for ill effects...I have been slammed in the past for saying yes...I stick to my opinion...which is my opinion and not fact. My husband is with the DEP...and works/tests public water supplies. It may not be the water itself but the method of transport to the tap. YOu will be able to find distilled water in Europe...hey, they have the same instructions as we do..and those across the pond also post on these forums.

Have a great trip... weighout the onslaught of opinions that will most likely follow my post ;-)

Thanks Tami,

I plan on looking for distilled water the best that I can. I guess I might have to go a couple days in Paris with tap water or without my humidifier all together.

If you would be prepared to injest the water (that is, drink it) then its OK to use it in your humidifier.

The instructions that come with xPAP systems in most of the world simply say "clean water" or similar... the fixation on distilled water in a particularly North American thing. Distilled water is not generally a supermarket commodity item outside North America, but if you don't want to use the local tap water there are a whole host of bottled "pure" waters that are readily available.

Also, prolonged use of tap water will not harm your machine in any way, as long as way of you follow reasonable and regular cleaning practices (which you should be doing for other reasons anyway)!

Hey, what d'you believe?
Paris is not a jungle!
You can find pure distilled water in any pharmacy, and the more commonplace demineralised water ("Eau déminéralisée") that's used for ironing in any supermarket together with household products.

@Bill Bolton
No, distilled water is not supposed to be taken for drinking: it lowers the mineral content of the body and can be harmful (of course a small quantity is not a problem).

Regular tap water is FULL of minerals. As it evaporates, the water goes away but the minerals remain. If you use non-distilled water, over a long period of time, that build up of minerals will start to be an issue. Are you ok with tap water for a while? I see no reason why not.

I would not go for tap water; if you cannot find Distilled, at least go with Bottled water. My reasoning is, while minerals just build up on the humidifier chamber, tap water is full of chlorine and other things that I would be afraid to breathe in as it evaporates.

I don't use the humidifier very often, and I use tap water with no ill effects. So might also be how often you use it :).

I tried using tap water for awhile and the hard water buildup was so discusting, so I switched back to distilled. I'm sure a few days on your trip will be ok though!

I have been using tap water for probably a year and a half now, I use white vinegar to clean the mineral deposit left about once a month (cleans it right out) and it still looks like new. It won't harm your machine in any way.

Distilled water IS evaporated water, when you breath in evaporated tap water what you are breathing in IS distilled water. Distillers evaporate tap water then capture it.

I've switched to tap water from my well. It's rich in minerals, and it does leave a scale behind. Every month or so I give my tank a soak in sodium hypochlorite (Tilex Mold and Mildew Remover) followed by a couple hour soak in CLR. Rinse thoroughly, and the tank comes out sparkling clean.

I used whatever non-distilled water was available around S. Africa for 2 weeks and the minerals did build up significantly.

During the trip, I periodically requested white vinegar from the restaraunts at the hotels to clean up the resevior and that worked fine.

At home I use distilled water for convenience, $1 a month, allthough I would like to find a way to refill the plastic jug with distilled water rather than having to keep throwing an empty jug away each month. I can only use so many empty plastic jugs.

Anyone have a cheap way to distill water? Maybe I'll separately post that question.

Just to clarify, there is no issue at all with drinking distilled water. It does not leach minerals out of your body. 95% of the minerals you ingest are from food not water. Overall, our bodies are around 60% water (blood is mostly water and teeth and bone are not of course), so why not put into it the purest form possible?

If someone can provide peer reviewed clinical data from a reputable journal stating otherwise and the physiological reason why, I would be happy to change my view.

The only issue with drinking distilled water is the taste (or lack of it). Thus the popularity of Perrier and other bottled water.
