Product review (3 stars): Wick not for EV100 - double check!!
Do not buy if you have the EV100 humidifier (white with the cylinder tank).  I used Amazon's recommendation, "other users also bought" and mindlessly clicked "buy now" and didn't look at the details that this wick filter is not for the EV100.  I found out the hard way after already opening the package and shoving the filter into the machine.  It's a slightly larger so it works fine but not perfect.
