This unit has interesting features for modern people, but is not user friendly for the elderly.
Pro: remote to adjust humidity level and steam level; timer.
Con: 14 nights without refilling is false advertising. Even at the lowest settings and nightly use only mostly good for only 3 1/2 nights. Elderly people will have a hard time refilling the tank and reinstalling it with full water in it without spiliing the water all over the place. You need to be a strong older person or need to have young muscles to help you out. The warm mist option is bad, as the water overheated and flowed out of the reservoir tank which could cause flooding if not caught on time. The unit is not as quiet as advertised. White dust was prevalent during the first couple of weeks of use, but now seemed to have subsided. The digital settings are not memorized by the unit, requiring you to reprogram when the unit shuts down on timer or after refill of water.
I am very pleased with this humidifier. It is very quiet and distributes a lot of moisture. Well worth the money. Would highly recommend.
