Query: Pain in the rear . . .

We used this humidifier for 2 weeks before I ditched it. The filter was gross, and I cleaned the humidifier according to the instructions. I borrowed my Mom's humidifier (bought 30 years ago), and it worked great -- then I realized how poorly the Vicks worked. After doing a little research, I discovered a humidifier at Target and have been very pleased with its performance. You still have to clean it on a regular basis, but there's no filter. I would recommend spending your money on the Crane humidifier.(...)
