Product review (3 stars): Vornado Replacement Humidifier Wick Filter
It works as described which fits well with my humidifier. However, filter lasts only about a month before goes bad before need to buy it again (daily use with adding water 2 times a day by NY tap water). It got dried up and started to smell from build up. If it lasts longer or cleanable, it would be more satisfy with the product.
