Someone knew what the heck they were doing when they made this! So it has many features....but the ones that I cared most about and are awesome are this. 1. I can clean the tank that hold the water very easily. our old tank part would get mildew in it and I couldn't clean it out. This one they made so my hand fits right in and I can wash it with soap and sponge and clean it. I feel much better about using this. 2. Sound! My son is very sensitive to noise when he sleeps, so our old humidifier would keep him up. This one is very quiet. 3. The remote control is awesome. I didn't think it was a big difference but it is. really easy and efficient. I will buy one for my daughter's room as well. Really great product!
