Product review (1 stars): Useless
I depend on my humidifier to maintain humidity for the well-being of very valuable wooden musical instruments. This filter doesn't wick the water up like the disposables I've been using. I checked the filter when I refilled this morning, and it was dry except for about 1 1/2" at the bottom. I turned it over, and an hour later, it was the same situation. I'm going back to the disposables. I'd rather pay more for a product that actually works.
