Title: Filters don't last very long
Review: We used these in our Vicks 1 Gallon Cool-Mist Humidifer, and each time I replaced the filter it would only last 2-3 weeks. These filters are a little pricey, so the maintenance cost for the humidifier quickly added up.We kept the humidifier running 24 hours a day in my sons nursery so that it was always on and ready to go when he went down for naps and bedtime. Maybe if you didn't run the humidifer for such long periods the filters would last longer.
