Product review (5 stars): Works just dandy
I had been cleaning an reusing my original 20 year old wick since I didn't use the humidifier all that much and they were very expensive at the time.  This year has been really dry, and since I had finally made Night Manager at Foto-Mat, I splurged and got a new wick.

I was worried that the straight through design of this one wouldn't evaporate much water but it does.  I am refilling a 2.5 gallon jug every few hours.  On high fan speed the wick keeps up and doesn't dry out at the top

Don't add anything to the water for fragrance as that will chemically clog a wick and it won't saturate.  Put an air freshener cone thingy on top of the unit instead.  If your furnace or A/C has FAN ON mode you can use that to move humidified air from the room to the rest of the house..
