Demineralized Water and CPAP
I am Bordeaux France and distilled water is hard to come by. Is it ok to use demineralized water?
Some say it is unsafe due to possible bacteria and that it may come from non portable sources. Is that true? Demineralized water is cheaper and easier to come by here.
The CPAP manual or the therapist says to use distilled water in the humidifier as it is free of minerals. This will prolong the life of the humidifier and prevent mineral buildup on the inside of the chamber making it appear dirty.
Demineralized water is the water that has been stripped of its minerals in every method that exists today. So, one method is distillation
, and other known methods are:
- electro dialysis,
- membrane filtration.
I repeat, demineralized water is the term for the water without minerals, and distilled water is the water stripped of its minerals through the distillation method
- when the water has been boiled off and recollected from steam.
Bottom line...there is no big difference between a distilled water and demineralized water, at least not it the finished product.
You can try the demineralized water for your CPAP humidifier, and if you don't have it now, you can use tap water (don't use tap water more that once a week). If you use tap water often, you will see a hard crud film on the bottom of your CPAP humidifier.
If you do get mineral buildup in the humidifier chamber you should be able to clean it with a white vinegar and water solution to dissolve the minerals.
A much better method
that tap water (if you can't find distilled or demineralized water) is to filter the water and boil it. The filter would remove most of the minerals and chlorine and some other particles, and boiling would take care of the microbial
concerns. This method is not perfect as the distillation process, which makes the water truly pure, but it might work pretty well.
And the last advice
for you - whether you use tap or distilled water - is to dump your CPAP humidifier water every morning. Bacteria can build up in humidifiers if the water is not dumped frequently.
I hope it helps. Don't be afraid to comment back. Remy Thierry
