Query: Love It!!

I am so happy with this humidifier! My son got a cold and immediately after we started using the humidifier his symptoms cleared up. And if you are only using it in a nursery or small bedroom, get this one instead of the 4 gallon tank. The tank only has to be re-filled every 24 hours, and the filter has lasted us 3 weeks so far. Replacement filters are not too expensive($5.99) and can be found at BabiesRUs **Be sure to rotate the filter...you'll get more use out of it. As far as sound goes...I don't know about other babies but my son has to have some kind of white noise or else he's waking up to just about anything, we keep it on the low setting and it works great. It's a little noisy on the high setting, but nothing you can't sleep through. Overall I would highly recommend this product to any parent or expecting parent.
