We have been using the Mist Aire for my baby's room since he was 3 months old and it works great for him. It's lightweight and easy to assemble and fill.
Just a quick note to mention that we are 100% satisfied with our new MistAire Ultrasonic Cool Mist Humidifier. Indeed, we ordered a second one and are expecting to get one for each of our kids as well. We love the simple operation, the colors, the adjustment options, and the size and weight of the unit.
This was a great fit for my windowless room especially with the approaching dry winter. It's quiet and there's different modes. Super easy to use and also affordable!
