Humidifiers are too big sometimes and it's hard to carry one around. That is why I choose Air O Swiss humidifier because they have humidifier at all types of sizes.

My personal favorite is the one that I have been using for many years which is the Ultrasonic 7133. This humidifier is quite old but it is the best affordable humidifiers that I can get. and it is still great compared to the newer ones. One thing that I like about this the Ultrasonic 7133 is that it runs quietly and I can relax and also read a few books when this thing is switched on. It also lets out mist and humidifies the room effectively. For a small thing, it really works hard.

The Ultrasonic 7133 is anti-bacteria and it has and it is built with an anti-bacterial technology which kills the bacteria's that is in your house. For one, I like this humidifier because it is very east to clean and maintain. I have been using it for two years now and it still works like I just bought it yesterday. Simply amazing I must say!
