This is my second one. The first one lasted just over 3 years and only broke down to calcium. We live in a hard water area, and after 3 years the motor could not cope. During the cold season, rehydrates the room for my kids. At all times, provides the night lights. Easy to fill, full water tank lasts several nights and if the kids have blocked noses, then the Vicks pads help. But these pads only last one night.
The most silent humidifier I have purchased to date. My son loves the projections also. (Doubles as a nightlight). Would give it 5 stars, except we had to purchase the filters in addition, to combat the white dust. If your water is remotely hard, I would recommend purchasing the filter from the get-go. The white dust otherwise covers everything in the room and is quite stubborn to remove.
