content: Thinking I would save a few $$$ instead of buying directly from vorando - I ordered these and learned the lesson of "you get what you pay for". After running on my voranado humidifyer for just 1 hour (in COLORADO where it's dry) the musty and mildew smell that was emitted from these filters stay in the house for several more days. I ordered filters from voranado directly and didn't have the issue. Don't bother with these, go direct.
