Product review (3 stars): White Dust
Had some initial difficulty but was able to correct. Humidifier was shutting down as if it had run out of water when it was still full. On bottom of filter is a spring like button which may have been a little stiff. Pushed button a dozen times to work it in and filter functioned afterward.
The filter itself is OK but I still get white dust on the TV that's located next to it.
