Product review (2 stars): Not good for Holmes 3607 Humidifier. Very flimsy with no outer support mesh to keep it all together when its soaked
Got this replacement filter for a Holmes 3607 Humidifier. It fits it, but very flimsy.  After using one filter for two days, it started falling apart in small sections.  This does not have the outer support mesh to hold it together when it is soaked.
