Speaking of Distilled vs. Tap Water.
#1
Which maybe we weren't.

I've read a number of threads debating what you should use. Generally it sounds like using tap water is a fine idea if you rinse your jug out every day. And that may well be true.

I'm not sure I agree though, and here's why: I manage a water district where we live. Our water quality is, I feel, and according to some very expensive testing we do, very very good. But it does contain the legally required residual of chlorine, which the government assures us is totally harmless. But they're thinking we're drinking this stuff, not breathing it. Secondly, depending on where you live, there is a substantial difference in how much residual chlorine will be in the water. Also many other factors such as lead and copper, and hundreds of other contaminants impact our water which again, while safe to drink, should we be snorting it?

I don't really know, but I think for the cost and efforts involved it is a prudent idea to only use distilled water in these things. You could use bottled "spring water," but probably not at any real cost savings, and since those things are choke full of minerals why do that?

Anyhow that's my take on drinking water based on quite a few years of reading our rather exhaustive test result studies on water we sell to our happy customers. Distilled water is pretty cheap, and I'm thinking its probably a good idea to use it in our water jugs.

Hi retired_guy! The labels on my humidifier say "Distilled Water Only" (and so do the printed manuals). Also, the tap water in my neck of the woods has quite a bit of minerals in it, evidenced by the buildup on shower doors / facets -- so I'm going to stick with the distilled water.

However, is there a chance that distilled water can go "bad" since there isn't chlorine in it? Bought a gallon, and it looks like it'll take me 2 weeks to use it all up in the humidifier. Don't want to poison myself accidentally, heh.

Properly distilled water is as pure h20 as you can get. It will not "go bad" unless you somehow introduce contaminants into it, which is not likely. That said, don't drink the stuff because without all the junk in it, it really doesn't taste that great.

If I were using my humidifier I would never use tap water.
Corrosive chlorine, dissolved minerals, etc., even when rinsed
leave residue that builds up. If you want your machine to last
use only distilled or DI water (de-ionized). Sure you might be able
to get by on tap water, but it's never good for the machine. I suppose
if your insurance gave you a new machine every couple years it
wouldn't be a problem.

The 'official' correct answer. is to only use distilled water, period. All the machine makers say so, and it's not just what you might end up breathing in, but also what might grow, clog, etc the machine over time.

That said, I use my well water for the last 4-5 years, with no (known) issues - but I am aware that I am rolling the dice.

If you use distilled water, keep it refrigerated and in a sealed container - any water will, over time, become contaminated, but by keeping it sealed and cool and taking it out and opening only to fill the tank and then return it to the fridge will minimize any potential growth in the container.

And toss any left over water in the humidifier tank in the morning and dry it, my preferred method being by forced air (just turn off the humidifier and auto-off, remove your cf card (do that first) and then run your machine for around 30 minutes to an hour, and it will dry the tank and hose and nasal pillow interior - it won't dry a ff mask, alas, because of the large open surface when not worn).

And yes, I also recommend distilled water only, for the machine's health and for yours.

Thanks Peter,
Well water normally is not chlorinated and normally does not contain the bacterias you would find in UN-chlorinated surface water sources. Wells are usually tested when first drilled then presumed to stay safe from then on unless something unusual happens. I did have a resident in our area that elected to build a rabbit hutch around his well head and managed to contaminate the thing. I'm sure that is not the case with you, so that's good. The actually quality of well water varies significantly from place to place, and sometimes even in very close proximity to other wells. In our area wells typically contain large amounts of sulfur which isn't really all that cool tasting or smelling. So for you, the issue is more about what trace minerals might be in there and whether or not they are damaging to you or your equipment.

Thanks Doc, good points. So, you wouldn't really recommend the microwave method for drying your stuff?

I use tap water and fine with that and the machine too ... she told me so
I encounter more risk crossing the street to buy the gallon of distilled water Smile

I don't think you have to empty the tank every night it's just as if it were in the bottle you took it out of. I have been filling mine up every night without dumping what is left over and all is fine. I go thru a gallon a month and I'll bet it sits in the store twice as long. How long do you store your emergency water? 6 months.
