Product review (3 stars): Very efficient, but degrades quickly and can't be cleaned many times without falling apart.
Works well, but doesn't last very long before efficiency goes way down.  I've carefully rinsed it a couple of times, but it gets more fragile each time.
I'd love a product that can be cleaned repeatedly, but the one I've tried is not very efficient - the humidifier barely reaches the green range right out of the box.
