Review on Holmes Humidifier Filter Pack HWF100 UC3 by Rovy Oppeneer

I've ordered a few times, I thought I got bad ones the first time, but no, the second ones were just as bad. The filters turn yellow and the black mesh begins to crumble after a couple of nights. I've tried to keep everything clean but these filters just don't last long. It's also odd that there are three packs since my humidifier only needs two. Realizing it was a bad buy, I decided to cut my losses and buy a humidifier that doesn't require filters. I don't understand the almost 5 star rating for them. In my opinion they are almost useless.
