Vicks Filter Free Humidifier, V4450

First of all, I want to comment on the previous person's review about where the 1/2 of water goes after she fills it up to the top. I noticed this as well, and I'm nearly 100% positive it goes into the machine. Bubbles go up in the water like it is going into another compartment where it takes the water from. Now on to my review, I purchased this because my 2 month old was coughing a bit and was quite stuffy after both my fiance and I had come down with the cold. My doctor told me to purchase a cool mist humidifier for the room. I was a bit hesitant about purchasing any humidifier from anywhere because of the pretty negative reviews, however I bit the bullet and purchased it, and I'm so happy I did. I have slept better, my son who sleeps with me sleeps better and my fiance sleeps better. I am stuffy when I go out into the living room and as soon as I go back into our room, my nose is cleared! I fill it up maybe once a day, sometimes twice because it is on, set to high 24:7, but who cares if you have to add water that much, seriously, it takes maybe 20 seconds to fill it up. It is a bit noisy on high, but I can't sleep without some kind of white noise (fan, a/c) so it doesn't bother me at all. It does the job of moistening the air perfectly, and I'm so glad I went with this purchase despite the bad reviews. You won't regret this purchase. Just a tip: If you have a stuffy son/daughter, my doctor suggested holding him/her right over the cool mist for a little bit. It seems to work great!
