Question about Air-O-Swiss 7133 Humidifier
I have purchased a new 7135, soaked the cartridge for 24 hours as instructed, removed a tablespoon of the granules from the cartridge, but still sitting on 30% humidity and no mist? Can you please help?
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.

I have had a similar problem with an AOS 7135 - usually after changing the granules in the demineraliazation cartridge. I tried it all, including removing some of the granules) and nothing worked.
My problem seemed to be stemming from the fact that the plunger on the bottom of the demineralization cartridge was not functioning properly. I think the plunger allows water to flow from the reservoir into the base. Mine was a problem of overtightening the cartridge after filling it (over and over again) so that the plunger did not meet the base properly any more.
My solution was to simply leave the cartridge about 1/2 turn looser than it was before. I now carry the freshly filled reservoir tank back to the base upsidedown to prevent any leaking onto the floor during transit.

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!

Spoke to rep and the Air less swiss tower type units have a round bronze oscillator at bottom of unit where tank goes surrounded by a white seal/heatsink. Newer ones are SStl. If your unit has cracks in the white seal not a good thing. Clean bronze carefully with 50% baking soda (lightly). and then rinse and try again.

I have owned several of these (Air-o-Swiss Ultrasonic) humidifiers. They never last beyond one season for me. I don't know if something happens to the membrane when it is stored, or if the problem occurs when cleaning the unit (following the instructions & using the recommended cleaner), but the membrane is clearly the Achilles heel of these things.
My solution was just to not buy these anymore. They work great, until they don't, then I have a $100-200(+) paperweight. Of course when this occurs it is well beyond the warranty period, so the company has never been of any help, since their obligation has ended.
There are many other brands of ultrasonic humidifier that will work much more dependably. They may not be as aesthetically pleasing, but they work season after season reliably.

Q: Unit is running intermittently.
A: How long has it been since the contents of the cartridge were replaced? If 2-3 months have passed, it is time to replace the contents of the cartridge. However the demineralization cartridge and or the granules must be exchanged at the latest after 6 months or the unit ceases operating at its full performance. If the contents of the cartridge were just replaced there are probably too many granules in the cartridge. Remove 2 tablespoons of granules from the cartridge.
