Review on Enhance Your Air Quality with ProTec WF2 Kaz Humidifier Filter by Brandon Wong

This replacement filter is a must have. I run my Vics V3100 at full blast every night and the filter lasts just under two months (the box says "The Cool Mist Wicking filter should be replaced about every two months depending on usage and local water hardness") When using a humidifier while on a humidifier running out of water during operation, the filter dries completely until you add more water. I have found that this practice shortens the life of the filter. 01/24/10). The name says "2 filters (3 pack)" - in fact there is only 1 filter in each box. The packaging is confusing as there is a large two in the top right corner of the box. However, if you look at the lower-right corner of the box, you'll see "Contains 1 filter" in much smaller type. So you order a total of 3 filters (1 filter per box, pack of 3 boxes).
