Humidifier is full every morning...

I have the humidity setting on 4 on my machine and every morning it barely uses any water. Could this simply be because the AC is running in our bedroom at night? Last night I tried raising the humidity setting to 6 but got bad rainout.

If anything, using the A/C would evaporate more water than otherwise (unless it drains into your room, which I doubt).

The problem is probably that you're in a climate or area that's already quite humid (now, if not all year) so the machine doesn't need to do much at all. You know the humidifier's a convenience, something some people need or want when necessary, but many of us never use them at all, or only in winter when central heating dries everything out. Have you tried not using it at all?

Setting of 4 on the AirCurve is about the middle of the road in terms of humidity to be delivered. If not much water is used then the ambient humidity in the bedroom is probably up high enough that the machine doesn't sense the need to add much extra moisture.

These machines with ambient humidity sensors in them don't put out X amount of humidity on top of the ambient humidity. They figure that setting so and so means whatever % humidity and if the ambient humidity is already real close then not much water is needed.

Humidifier does seem to be working since higher setting gave you rain out in the hose (easily fixed with a heated hose if you like the extra moisture and want to use it and still keep the bedroom cool).

I have an AirCurve 10....I think I have it set for Auto humidity which I think is 85% (I choose manual heated hose temp)...and on nights where maybe it has rained during the day or night and the ambient humidity is fairly high I might not use much water at all but on the nights where the ambient humidity is on the drier side I might use almost all the water.

The first question is whether the water is warm in the morning , or just room temperature? If it's warm, the heating element is working and in use. If not, it's broken (or otherwise not active).

Since you report rainout at your prior setting and nothing at your current setting, have you tried a setting halfway between?

Note that if you're running the air-conditioning, the humidifier should put out more, not less!

Not necessarily broken if the heater plate is cool. It could just be cycling and happen to catch it when it is off.
If the humidifier sensor has determined that there is no need to add more moisture to the air for whatever reason then the heater plate won't need to add the heat to create the extra moisture. They can go through cycles...on/off/on/off for indeterminate periods of time and it wouldn't be impossible to just happen to check in during the "off" cycle.
So in the morning after a night probably is not the best time to check things out.

In the evening at the start of the night and using the preheat feature is probably a better time because when using preheat you know for sure it should be on.

Also note...I am using the air conditioner this time of year and the water consumption will still vary considerably depending on the weather outside.

thanks for that insight. If I may ask: how confident are you about that?

I'm just wondering now because I always thought (thought and not know) that they have a thermometer build in and adjust the temperature in the humidifier accordingly to that. So if it gets very cold in the room - because of the AC - the relative humidity drops anyway - but there is not so much temperature for the water needed, because too high would cause rainout because of the low room temperature.

Don't get me wrong - I'm really curious about that, because I made the same or equal experience as the OP. If the room is colder - less water usage - no matter the humidity in the room. Room gets hotter (as in the summer) more water-usage ... humidity in the room has only little impact.

the *hose* has a thermometer at the end of it, so what whatever hose temp is set can be maintained. the humidifier has a humidistat that measures the humidity in the room, so it can calculate how much extra humidity to add to reach the desired amount.

To Pugsy,

I said broken or otherwise not active!

Otherwise not active could mean that humidification is not called for based on the settings, or that it is so cold in the room that any humidification would cause rainout.

The converse is clearer, of the water is noticeably higher than room temperature, it surely is working!

the s9 has a preheat function, the 10 should have it too. That is an easy check if it's working. other than that it's settings, heated hoses and/or hose covers

The most important thing is not discussed. Do you get nasal dryness? If not, you may not need the humidifier at all. It's one less thing to "mess" with.
