Product review (5 stars): Works great!
Ordered 4 and they work great in our humidifier! It was a little odd to get 2 in the mail and then receive the other two almost week later...fortunately the packing slip noted that there was a second box, although with the delay in getting the second package, I was concerned that it got lost..perhaps a note stating that it would come a later day would've nipped my concerns.
