Product review (5 stars): It's GRRRREEEEAT!
I was a bit skeptical about buying a generic replacement filter wick for my humidifier, but this thing is FAR better than the brand name one that came with it new!  The original was held together (and upright) with a plastic mesh, and it tended to sag when the wick was wet and I removed the fan assembly.  This replacement is held together with a stainless steel mesh, which is much stiffer.

The wick itself is nice and thick with slightly larger pores, and it DEFINITELY works much better than the original.  If my house is dry and I put on a full tank of water, it will drain it within 6 hours.  The original would take closer to 12 hours to drain the tank.

I have already placed an order for a couple more of these wicks, which will most likely last the lifetime of the humidifier.
