This was the worst product I have ever purchased. The motor is so loud that you simply cannot use it. I tried to run it many times to see if it would get quieter but it didn't. I had to let friends hear it so they could know what I was talking about. They couldn't believe it either. PASS on this product. Save your money and buy something else that you can actually use.
I'm REALLY pleased with this purchase! I've had quite a few humidifiers over the years and this is by far my favorite. It works well in medium- larger rooms (hard to get for this price) and it's very quiet. SUPER easy to fill without spills and stuff, and I have hard water that leaves deposits and clogs things up, and so far this is performing fantastically! Even my cat approves of it's level of noise, since he doesn't try to attack this one.
Overall, though? My favorite feature is just how easy it is to fill! I definitely suggest this one!
