Vicks V745A is perfect to use when flu and cold season rolls around. It is lightweight, relatively inexpensive, has two moisture settings (low & high), auto shutoff and best of all no filters to replace which is a cost savings over models with a filter. The manufacturer has reported that it runs for 12 hours on the low setting.
It can become noisy when the high setting is used but runs pretty quietly when on the low setting. The handles on both sides make it convenient when moving the unit, when filling it and when carrying from room to room. Relatively inexpensive compared to other humidifiers/vaporizers. If you take good care of the unit it should last a few years. All in all this is a very nicely built, it is affordable and easy to use. It also looks nice.
