Product review (5 stars): just like the ones I ordered
I hadn't removed the filter(s) from my humidifier until these arrived.  In the write up it mentioned there were two filters so I thought I'd have a back-up.  When the box arrived I was shocked to the filters were small.  Then I went to rinse out my old filter to see if I could still use it while waiting for the correct fit filters to arrive and found the filter wasn't a large one but two small ones, just like the ones I ordered.  It was a D'uh moment!
After changing out my old filters for the two news ones my humidifier is running like new.
