Product review (3 stars): Fit Vornado humidifiers, only last a few months.  Very spendy for what they are,  look for a generic.
Clearly these work and fit Vornado humidifiers with out any issue.

The cost of these is far to high.  For something i have to replace every few months it should be a few bucks not the 12 they charge.  I would recommend looking into the replacement wicks for your humidifier before making the decision on buying one.

If you live in an area with hard water these will not last more than a few months.
