Aquafina is rated as 4ppm TDS water so it's fairly close to distilled.

Aquafina, or any bottled drinking water is just fine, but is more expensive than distilled, and offers few benefits over most municipal tap supplies. Huh I do use bottled water when traveling, and whenever we are at a location with well water or questionable quality.

Dont-know Whatever works. From all the attention it gets, you'd think the water in our humidifiers really made a difference.

RE: Water change
Stop & Shop offers giant one gallon containers of distilled water for 99 cents. I have no idea why anyone would be bottled water in their CPAP machines.

As for why you might use distilled water, I had a humidifier a few years ago that I completely ruined because I used tap water, it gunked it up with concrete-like scaling. As CPAP's cost over $1000 a piece, as opposed to my $40 humidifier, I'd rather not take the chance.

I agree if you are in the US where distilled is 89cents a gallon at Walmart. But overseas, distilled is 5x - 20x more expensive than purified low TDS waters like Aquafina.

RE: Water change
There is no two way about it, distilled water is the way to go
I can get get distilled water from local supermarket for use in steam irons/mobs but the label warn, not to use in medical equipments

I've been using tap water for a while, no problem with gunks or build-up, some tap water quality is better than others
Definitely not using tap water if looks dodgy or smelly. The rule of thumb for me, if the water is safe to drink, also safe to use in my CPAP humidifier, some might have problem with that, I guess, each to their own

I'll be drinking a lots of chilled tap water today plus some other refreshment to keep cool, temp going to be in high thirties

I would think that a good, well chilled Australian beer in a frozen mug might be an even more refreshing drink in the high thirties! Big Grin Dont-know

Indians drink hot Chai tea on hot day to cool down, I suppose there is a logic to it but prefer the above, a lots of thoughts went into it Smile

I have a water softener and use tap water.

ditto here. Rinse it well and add a little dish detergent once in a while. (the water does not go thru the machine.) If you don"t have a water softener, a vinegar and water soak will remove cloudiness from tank. (rinse well, LOL)Smile

RE: Water change
I'm with the distilled water users. It's cheap enough (at least here in the US), I only pay about .88 a gallon. I have never had any buildup of any kind, and don't have to use anything harsh to clean the tank, other than Dawn Soap, rinse, and air dry. Compared to the cost of CPAP machines, why not use it? Dont-know

RE: Water change
I'm also in the distilled water camp:

1. It's cheap
2. Resmed says to use it and if you don't and you have an issue with machine/humidifier you may have breached the warranty by not following the written instructions so why mess with it given #1.

FWIW, my DME said using filtered water through a Brita type filter would be fine too so I doubt #2 would be a real threat but again given #1 why bother.

RE: Water change
As a side note here, I have read other posts here reporting low water consumption and wonder if they are using the proper procedure. I think most of them are during winter months.

Let's face it, if you keep your bedroom pretty chilly and you also keep your distilled water in the same room and furthermore don't preheat the water before starting the flow generator, it won't be delivering much humidity for a very long time, perhaps the entire first half of your sleep session.

Some may not be aware that their flow generator has a "Warm Up" feature or haven't used it for whatever reason. My S9 Auto does anyway, perhaps some don't.

I also keep my distilled water jug sitting with its edge partially over the floor register in the warmest room of the house so it can always be slightly above room temperature. You may also decide to warm the water by microwaving it. Whatever you decide will be better than using cold water from the get-go, especially if you use tap water, which can get very cold during winter months in some areas.
