I've bought several and still own a Lasko tower fan, but they are known for being very difficult to clean. The rotating fan blades tend to get caked up with dust over time, and Lasko designs the unit to be disposable. Depending on the model, you can disassemble it but it takes some effort.I've got two of these...very good. Moves lots of air.
