Customer Review: Gold Membrane Disintegrated within 2 Weeks
Summary: 1 Stars
I had the product about 2 weeks, and decided to clean it, according to the provided maintenance manual. I've noticed that the gold paint on the membrane was in very poor condition and small chips of gold paint were all over. However, the manual says the membrane should be cleaned with the soft provided brush. So I did. That completely destroyed the gold paint layer and the device is not producing vapor any more. The most annoying thing is that the warranty is valid only if the purchased device is registered within 10 days of the purchase, which I had not done (didn't have time to read everything that came with the device). I've just sent email to the support and asked for help with this... We'll see. In the meantime, DO NOT BUY THIS DEVICE UNTIL THE COMPANY CLEARLY STATES THE PROBLEM HAS BEEN FIXED. Further, I find annoying that the warranty is invalid without registration. Perhaps we should be buying from a company that has more confidence in their products?
Update: 2 weeks later, I'm still waiting for the problem to be resolved. After a lot of explaining (I spent roughly an hour on the phone and sending emails), they told me someone would contact me and tell me how to printout the shipping label (for return). A week has passed and nobody contacted me...
While I'm waiting to solve the return, I'd also like to comment on how the device was working, while it was working. The device is fairly quiet itself, but the water is occasionally bubbling, which can be loud. They could have solved this differently to avoid the bubbling. I had no problems with white dust some other reviewers mention, but that might be due to the softness of the tap water I'm using. The vapor does have kind-of metallic/plastic smell, but it's almost undetectable unless you are very close to the vapor, so that didn't bother me too much. The design is quite functional, but I haven't managed to fill the tank without spilling some water around, because the tank is immersed into the base, which always contains some water. Thus, if you take the tank off, the water drips off it. I haven't checked how precise the built-in hygrometer is, but I found the device reliably switching off and on according to the desired humidity setting. So, although I can't comment on the absolute precision of the hygrometer, the relative precision seems to be fine. If the device were actually working, I'd give it 3.5, perhaps 4 stars. But because it is not working, I'd suggest you wait until Air-O-Swiss announces on their website that they have reliably fixed the membrane problem. The returns are just too much hassle.
Final update: Around mid-July (a month after I started the painful process of return), I got a phone call from Air-O-Swiss asking me for some number their support sent me by email a couple of weeks back (!?). I didn't understand the point of that phone call, they could have just checked their database/email inbox. A week later I was asked to provide the details about the device (probably for the 10th time). Finally, I got the label and shipped the device back. The pinnacle of the Air-O-Swiss incompetence was the email from July 27th (after they received the device): "We found a discrepancy in the information on file for your defective humidifier. So, that we may send you the correct replacement unit, would you please describe the unit you sent back to us? Or, can you tell us the model number of the humidifier? (example...AOS-7131, AOS-7135, AOS-7145, etc...)" This is simply the most striking example of total incompetence I have ever seen. They have the defective device on their desk, they should have my order in their database, and they are wasting my time asking about the model??
Finally, I got the replacement device on Aug 5th, but haven't yet tested it, as I was on vacation. The whole return process took slightly more than 1.5 months, and probably 10-or-so hours of my time. Their support exhibited total incompetence and disrespect for my time.
I just checked the membrane, it seems to be in a much better shape than in the first device.
Another update: The new membrane lasted about 3 months and then disintegrated, the same as the first one. I'll return it and ask my money back. Long story short: This is not a product, this is a piece of junk.
Description of Air-O-Swiss AIR-O-SWISS 7145 Ultrasonic Humidifier
The Air-O-Swiss Ultrasonic Cool Mist Humidifier 7145 is a high-quality ultrasonic humidifier featuring a premium titanium transducer surface, which uses adjustable high-frequency vibrations to turn water into a micro-fine mist, which is blown into the room to evaporate. Unlike other ultrasonic humidifiers, the Air-O-Swiss titanium transducer surface is much stronger than ordinary metals, resists rust, lasts longer and requires less cleaning. The Air-O-Swiss 7145 features a tri-band microbial protection system which guarantees that the water will be kept free from harmful bacteria and viruses. A replaceable demineralization cartridge (Ag+ Ionic Silver Technology) helps reduce ?white dust" (lime scale and other mineral deposits from the mist output). In addition, the patented Ionic Silver Stick uses aqueous silver ions to control microbial growth for up to one year of continuous use. It is self-regulating and maintenance-free.Kitchen and Housewares
