Product review (1 stars): Filter does not wick out of the box and doesn't last
The first filter I used out of the box did not wick at all.  After 1 full day of use, no water had been absorbed into the filter or used by the humidifier.  I gave the filter a diluted vinegar bath and it worked great for 1 day and then started drying out again.  I have been using that filter for a week, gave it 2 more vinegar baths and it is about done.  This is the worst filter I have bought and I made the mistake of buying a 6 pack.
