Lasko Products 1128 9.0G Recirculating Humidifier

The Lasko 9-Gallon Recirculating Multi-Room Humidifier works great in my house. It's February in Michigan and this unit has kept our 1800 sq. ft. home at a comfortable humidity even on days with single-digit temperatures. It's easy to fill, using its own fillable container with handles. It has a viewable section so that you can see the water flow. The only down-side so far has been the fact that it doesn't automatically shut off when empty. It just keeps running. The only indication you have that it is empty is the lack of water flow in the view window. In the worst weather, I have to fill it daily. Other than that, it has been a great unit so far. I haven't had to replace a filter yet as I've only had this a couple of weeks so I don't know how expensive they are yet or if there are mold issues. Supposedly there shouldn't be but we'll see. I haven't found anything in the directions indicating to add something to the water for microbe prevention so I'm hoping it won't grow mold. I'll be keeping my eye out for that.
