My granddaughter has had a lot of nosebleeds and sinus problems due to dry air. After a long search we decided on this Vicks model. It's easy to fill and will hold vapor for over 12 hours even on a high setting. The low setting is said to last 24 hours, but I'm willing to bet it will last longer. After turning it on, it only takes about a minute to produce warm vapor. It came with a medicinally scented sachet to insert into this device, but we haven't tried it yet as she's not overwhelmed or ill. However, this is a great option. I recommend this device and I don't think it will disappoint anyone.
