As soon as we start running the heat, I set this little powerhouse up🙌🏼💦💧 Our skin needs extra moisture in the winter months. This is also so soothing to have running overnight. The tank lasts 8+ hours I love my Levoit Humidifier! Mine is 5 years old, so linking a couple newer ones. You can also use essential oils in it, but I choose not to do that anymore because it requires cleaning a LOT more often. LTKHome LTKFamily LTKVideo
