Product review (2 stars): Crusty, ill fitting, cut myself on the metal.
Have to be honest, don't like this filter.
Went yellow and crusty at the bottom(water end) in the first tank of water. The original filter in Vicks Starry Night humidifier did not to do this so I know it's not our water or air quality. The original filter did not discolor or smell weird AND it did not have metal in the middle- which I cut myself on trying to make the darn thing fit properly. The original filter supplied by the manufacture lasted just over 30'days running 24/7. This filter didn't last the week! I see most of the reviews for this brand and others are not favorable so I will call the manufacture and see if I can order a filter from them direct. Keeping my fingers crossed this brand of filter is not my only option.
