Product review (5 stars): Finally!  Replacement filters that fit Holmes HWF65 Humidifier!
Have a Holmes HWF65 Humidifier that still works very well, but have had a problem finding replacement filters for it, since Holmes has discontinued the filters for this particular humidifier.  These work great!  At first glance, looks like they may not fit, but they do.  Just bought one pack and have only used one so far, not how long it will last with daily use.  At one month in, still looks like it's in good condition, no mold on it.
