The Air O Swiss Humidifier 7142 I purchased this humidifier after trying 4 other models and being disappointed in the quality and/or sound which was too loud for sleeping. I wanted a warm mist humidifier and this one, since it has both warm and cool mist options, seemed to fit the bill. I am really pleased with it, especially the fact it will run all night and half way through the morning without a refill. I keep it at 50-55% humidity. Normally I use the Sleep Mode which automatically turns the steam off and on to keep it at the humidity level I desire. It's quiet, except for some gurgling noises when the water moves about into the base from the tank. There are a couple negatives however. The first negative is it does put out a lot of white dust, even using the included cartridge that is supposed to remedy this. I really didn't see it that much on my furniture but when I went to check my furnace filter it was clogged (we recently had put a new filter in so knew it was the humidifier and we never saw any of this before). This was only after about a week of use. I also noticed that the dust was settling on my computers and knowing we were breathing that stuff all night almost made me return this. After reading that using distilled water would keep it from happening, I went and purchased 10 gallons and the machine used 2 full gallons the first fill. We tried it last night and there is virtually no white dust on any of the computer stuff or anywhere else today. You can also use reverse osmosis treated water to do the same thing. Eventually I will have to get a reverse osmosis unit because the water costs 88 cents a gallon and it will be costing me $26.40 a month just to run this humidifier during the winter. Starting in October through April while our furnace is still running that comes to $158.40 for 6 months of water. After paying almost $200 for the unit itself this is just not practical, but at least for now I can reap the benefits of the humidified air at night and it's worth the cost. The second negative is the weight of the tank when filled. I am a small person and trying to carry that filled tank from the sink to the humidifier really hurts my arms. Not only that, since it fills from the bottom you have to flip it over and get it set squarely on the base. It doesn't seem to seat easily either. You have to fidget around with it to get the tank squared on the base properly. Because it's so heavy this is really an uncomfortable chore. If you are a big guy with strong arms it wouldn't make a difference I'm sure, but I don't see how an elderly or small person would be able to do this easily. In spite of those 2 things I would buy this unit again. I feel it is the only humidifier I've tried that actually does what I want it to and even the humidity indicator works properly (so many of them just don't). I purchased an external humidity indicator that sits next to my bed and it's spot on with this humidifier. Since I have only had this about a week, I'll update my review if things start going wrong. Before signing off, I do want to strongly recommend that you use distilled or reverse osmosis water if you purchase this unit. It's not worth breathing in all the white dust otherwise. Hope this review helps! February 26, 2013
