Product review (4 stars): Solid buy.
Every time I buy a cheaper filter and follow up with a better-made one, Im almost immediately reminded why its worth spending the extra few dollars. Ive only had it for a few days and the amount of gunk its sucked up from the air in my place is amazing. Having a fully functional humidifier that isn't circulating as much mold and dust is great, especially living in an old building.

It shedded a bit when opened and didn't come with instructions, but I knew what to do to get it ready for use.
