distilled water

they say to use distilled water in my cpap,what if i use tap water..are there any health risks in useing tap.or is it something else ???

Using water that isn't distilled means you have to clean your tank more often or you'll find crud in the tank. Distilled is cheap enough, and nothing grows in it. Occasionally using tap or bottled water is ok, but be sure to clean the tank well.

If you don't want to buy distilled water, you could boil tap water and then let it cool down. I get my distilled water at WalMart for 88 cents a gallon......

My s9 tub can not be taken apart so I have used nothing but distilled water ( 6 months ) and it looks as new as the day I bought it.

For those of you who would use city tap water, most cities in the US put Chlorine and fluoride in their water which are gases that will come out of the water and you will breathe then in, if you don't boil the water first to get rid of them

Conversely, if you use well water, you might grow some bacteria in the humidifier.

Yes it can, I have done it several times now:

Yea, I remember watching that video. I was going to try it but chickened out. If I starts looking like it needs a cleaning I'll try it.
Thanks for reminding me about the video Katie.

I'm starting to get concerned that store bought distilled water isn't as distilled as it use to be.

The reason is that people want purified drinking water (free of bacteria and pollutants), but there's a realization that we get some mineral via our water. So they are starting to put the minerals back in water to make up for that.

I've only seen it once on a bottle of distilled water, but I'm nervous that good old distilled water may not be what it used to be if the idea of putting minerals back in becomes pervasive.

Distilled water isn't for drinking. You buy drinking water for that, either spring water or mineral water. Distilled water is mostly produced for use in batteries, irons, and small humidifiers (incl cpaps). So why would anyone, least of all a supplier, add minerals back into the water?

It's possible that some (unscrupulous) suppliers are supplying reverse osmosis (RO) water and are labelling it as "distilled". While RO water has significantly reduced dissolved salts in it, it's not as pure as distilled.

I'm not sure that I follow your logic...distilled water is without minerals. If minerals are added, it's not distilled. Hose Head is right...distilled water is not for drinking.

Boiled water is never a long-term substitute for using distilled water in your cpap humidifier. The only reason you would boil the water is to kill any bacteria that might be in it. But in so doing, you are increasing the concentration of the carbonates that are dissolved in the water. You want to use distilled water in your cpap precisely because distilled water has NO carbonates in it.

If you have no alternative to the use in your cpap humidifier of water that may have bacteria in it, then boiling and cooling the water before use might be a short-term solution. However, it's not a longer term answer because in time, your humidifier will be encrusted with carbonates. Just look at the bottom of your kettle to see what I mean.

If you feel you must use anything other than distilled water in your cpap humidifier, then be sure to discard any left over water after every use, and periodically fill and soak your humidifier tank with vinegar, followed by a thorough rinse with clean water (weekly is suggested).

I also get my distilled H2O at walmart it's under a buck a gallon, and a gallon lasts about 2&1/2 weeks so it's well worth the cost and you won't have to clean you tank out all the time

There's a link to a video, buried somewhere in one of the threads, showing how you can take apart the S9 regular tank. Doesn't look too difficult. Probably couldn't do it more than a few times before the tabs would be worn out and the tank wouldn't seal tight.

The easy way to keep the tank clean is use distilled water. I probably don't use more than a nickel's worth of water a night.

EDIT: I see the links have been given above. Should have read further before replying!
