Great humidifier for my grow room. I use a 400 sqft converted garage for plants. This keeps my room and plants at a constant humidity level of 60-65%. Depending on the outside temp, I don’t have to refill tank but every 14-24hrs, but it has lasted 36 hours. Good in my opinion, it is winter and very dry in my area.
I really like all the different settings you can set. It automatically shuts off when humidity set point is reached. Easy to refill the tank. I will be purchasing another for my living room!
