I got this humidifier as a gift.  I love using these nightly in my kids room because it helps them to breath when they're congested.  My son has sever allergies throughout the year but especially during Fall and Winter.  So during these months, I run it nightly.  I can tell the difference when I don't run this that when my kids wake up, they are more congested and have a hard time.  I like that the opening of this humidifier is a bit larger than others so it makes it easier to clean.
