This humidifier did not work. Contacted AO and they just referred me on to the supplier. There was a real language barrier and they just sent me a copy of the user manual after a few days waiting. Then eventually they admitted that not only was this not a popular machine and maybe it was not working. The humidifier never even got to the point where it took the water in from the resevoir.

Brought this 6 weeks ago. Works well until you have to replace the air filter. Because you simply can't get them anymore. This product as been discontinued. You can no longer buy parts . No one should be selling this humidifier. So kindly refunded me.

This product was not able to cope with our room size which is less than the square meterage advertised. I concider it in our case a complete waste of money, of no use,back in box, which hurts,

I found it exceedingly quiet but realised the humidity at the moment in my house is too high to need. Might be useful when I put on heating

Quiet, tank lasts several days even with heavy use. Seems to be helping. Easy to set up and use.

It has been life changing for me .. recently diagnosed with a chronic breathing condition and totally shocked me just how positive effect the humidifier has been ... I then ordered another one. Use it daily ... one upstairs and one downstairs... AO Amazing x

Very effective humidifier. Simple to use and maintain. It has made a real difference to the air quality in my home.

Bye Bye stuffy , blocked nose. works night after night. Brilliant
