I love this Pure 3 in 1 Humidifier. I really like the scents they are calming and warm. I have insomnia about 3 nights a week.  You can get scents to help you sleep help you relax or help just calm you down.  The lights changing also help me relax and not have so much anxieties.  This helps me center myself and brings peace to my spirit. I fill it with water and what ever scent I need and this thing runs for hours.  If you want a Humidifier that won't let you down, pick up a Pure 3 and 1. Great product you won't be disappointed.  This is my second one. I absolutely wore the first one out after years of using it.
