Product review (1 stars): and every one has had a metal open mesh reinforcer so that it holds a nice cylindrical shape
I've bought filters annually for this unit for years, and every one has had a metal open mesh reinforcer so that it holds a nice cylindrical shape, with the sides fully exposed, giving maximum surface for the water to evaporate from. This thing had no such reinforcing structure, just the cloth-like wick. Which immediately, on getting wet, collapsed into a shapeless lump. Which was useless!!! I'd give this zero stars if I could. Now I have to go out and find one that has a proper structure to it. I also have to note on my calendar to NOT ever purchase items from this brand again.
