Our son has struggled with upper respiratory issues since he was born, and this cold winter has been brutal on him. We got the Duux humidifier, and it has REALLY helped. We are able to set it up very close to the crib, and the immediate mist calms him practically immediately. I tried adding a couple drops of eucalyptus oil also, and he seemed to like that as well. I plan to buy also the air purifier for the pollen come spring...this one works so well I am confident that will be great too.
