Product review (1 stars): Not what you get - beware!
Please beware that you will not get the advertised product - what you will get is a boneco cartridge instead, available on amazon for half the price. I understand that boneco has bought air-o-swiss, and thus, the cartridge works in my air-o-swiss humidifiers; however, charging it twice just for a nice picture on the amazon page is misleading. Do not buy. If you have air-o-swiss humidifiers, look for boneco a7531 product instead and save yourself 30$.
