Just wondering if anyone had any thoughts on the Dyson humidifier? It's expensive, but my son is pretty much up all night coughing. I know I could get a cheaper one but we will probably put it to heavy use. Need something that doesn't get everything all wet and is easy to maintain. I own a Dyson vacuum and I like the quality and ease of use( and cleaning) of their products. Let me know if you own one or know someone who does! Thanks!
