Question about Swiss AIR-O-SWISS Ultrasonic Humidifier - Model AOS 7135 Humidifier

Open Question

Air-o-Swiss 7135 Humidity reading is 25% and never changes

The digital reading says 25% and never changes. I have put two thermometers with humidity readings and they both read about 50% humidity.

Is there any way to do a reset or is the unit defective?

    Hi,

    I have exactly the same problem with mine. Any solutions?

    Exactly the same problem; called customer service which advised the following as a reset procedure (which did not help with my device):
    1. Turn the unit on with max humidity and max fan power for 15 min.
    2. Turn off and unplug the cord for 30 min.

    After those steps the unit is supposed to be reset, but I saw no change.

    I suspect the following:
    1. 25% is the unit's minimum reading.
    2. The reading tries to account for surplus humidity near the device compared large rooms' ambient humidity, by subtracting a fixed level, maybe around 10%.

    The above two (remember those are assumptions) would keep, in many situations, rooms with 35% and less humidity levels, showing 25% constantly.

    I suggest a simple test to those who asked (and to myself, since I haven't tried it myself yet). Move the device to another area in the room, where the air is more standing, like near a corner. See if there is any change...

    I suspect the accuracy of my air-o-swiss humidifer is wrong most of the time. When I place a small portable humidistat beside the humidifer it reads 50%. The humidifer displays 30% most of ther time. I suspect there are problems with the Air-O-Swiss humidifiers. I do not recommend them for that reason and also for their poor service.

SOURCE: Air-o-swiss 7135 humidifier not misting

I read this and thought "Hurrah! My solution at last!" But I tried it -- unscrewed the cartridge at least a 1/2 turn looser -- and still no dice. No mist, that is. Any ideas out there? This unit used to work just fine, but I put it away in storage for about 9 months and now it fails to produce mist (but appears to work otherwise). Darn it!

WATER LEVEL FLOAT DEVICE PREVENTS UNIT FROM TURNING ON,EVEN THOUGH WATER TANK IS FULL. REMOVED SOME FILTER MATERIAL WITH NO EFFECT. FLOAT IS FREE WITH NO RESTRICTION.


These hints are from the air o swiss webpage.
Q: No mist / unit is not working / empty indicator keeps flashing
A: Fill up the water tank. Check if water is flowing through the demineralization cartridge (attached to the water tank cap). If the water tank is full but there is only little water in the base it indicates that the water is now flowing through the demineralization cartridge.

  • Wait for 15 minutes to allow the mist to come out of the unit.
  • If the unit is not working and the empty light is not flashing you might have set the desired humidity too low and the current humidity level in the room is higher. That is why the unit switches off automatically.
  • If the empty indicator continues flashing and the tank is full, water is not flowing through the cartridge. Exchange the cartridge or the granules in the cartridge after 2-3 months, in areas with hard water exchange the cartridge after 1 -2 months. However, the demineralization cartridge and or the granules must be exchanged at the latest after 6 months or the unit does not reach its full performance.
If the granules are new, see the following instructions:

  • Make sure the cartridge and/or granules were soaked for 24 hours, water takes longer to filter through dry granules in cartridge and into the base. Next, remove 2 tablespoons of granules from the cartridge, and throw them away. Too many granules in the cartridge it does not allow water to flow from the tank to the base.
If your issue is with the float and not the mister, then you have to make sure the float is tripping the micro switch that turns the machine on. Some units the filter will not allow the float to hit the switch if the filter is not installed correctly. If everything is in correctly and the float is tripping the switch, then the micro switch must be faulty.

The Hygrometer on my Air-O-Swiss U7142 reads 25% all the time. I assume its not functioning properly as I have other hygrometers in the house which say higher readings. Is there a known way to fix this? I...


I have got the same problem with my u7142 unit. This most probably means that the hygrostat inside is either broken or it has been heavily covered with the "white dust" in case the demineralization cartridge has not been changed for a long while.
To resolve it you have two options: either clean the humidity sensor or replace it. The sensor is at the bottom of the front panel, so you need to disassemble the front panel only, no need to open the whole unit (note that there are 2 screws at the bottom holding the front panel also). You need to get the sensor out from the printed circuit to open the cover and clean the surface of the sensor with something (blowing air does not help; you need physically touch the surface with something). If it does not help then you can go for the second option to replace the sensor, the type used in the unit is SYH-1. It is not a pricy element so you may go straight to the replacement if you find a shop nearby to buy it. I have simply replaced the sensor and now the unit is showing the proper humidity value and adjusting the steam automatically again.

I can't tell if it is working. The humidity reading in the house is 20%. When I open the humidifier, I see that the water is trickling over the filter but it doesn't seem to ever get saturated.


Hello, is there water going down the drain tube, if so then the humidifier is working. The pad does not really get saturated the water just trickles on the pad and the the fan blows it into the air duct. your outside air temp determines what your humidistat should be set at.

Outside Temperature -10 F 0 F 10 F 20 F 30 F Recommended Indoor
Relative Humidity
20% 25% 30% 35% 35%

Air-o-swiss 7135 humidifier not misting


Ours has done the same thing after only 2 weeks. From article research, it appears that this occurs to everyone after cleaning it with the EZ Cal that is recommended. From looking at our unit and figuring out how it works, it appears as though the Ultrasonic Vibration membrane has stopped working. This particular piece is responsible for vibrating the water and making water mist particles which are blown out with the air. We will be calling the manufacturer on Monday to register a complaint and request a replacement unit.
