Product review (1 stars): ... Air-O-Swiss humidifier I bought is a disaster and a waste of money
The Air-O-Swiss humidifier I bought is a disaster and a waste of money. I have since bought two replacement cartridges and hydro cells but will probably not use them. The machine keeps indicating it is out of water, even though it is full. I have tried removing granules from the cartridge, and the machine runs for a few minutes and then indicates again that it's empty. Our water is well within acceptable range and is not at all hard.
