Product review (1 stars): One week and already have mold spots
These are completely pathetic filters. I've  had them for a week and they already have mold spots on them. Definitely not what I want being put into the air to be inhaled. The ones that came with the humidifier originally were reusable and these aren't. They are more paper like then anything. Also, they come in packages of three when the humidifier takes two. I won't buy these again. I'll put the money towards a new humidifier that doesn't use filters,
