Product review (3 stars): Works
I love the Vick's Starry Night Cool Mist Humidifier that I use this filter for. My house is very dry in the winter so I run the humidifier in her room on full blast every night so this filter really only last about a month then turns yellow. It needs to be re-wet daily or it will dry out, but again I run her humidifier daily. The price is reasonable too.
