Love this humidifier. We have used several different ones in the past and this one is the easiest to clean. Ordered it at the end of October 2023 and had a long run time and was quiet. Not full 5 stars because the tank lid spring popped open making the humidifier defective -- bad timing since we are in a rough cold winter. Customer service was excellent (<1min hold to talk to a human and no-fuss!) and they covered a replacement with the warranty. Will happily give a star back once the new one arrives!
