Query: stinks like Clay

For the first day or two this humidifier pad work like it should. As soon as the clay was saturated, it made the air in the house smell like clay. When my when my birds would fly, the air was cloudy wih microscopic clay particulars. Ended up putting the pad under a strong stream of water to wash off the clay. Kind of defeats the purpose of the pad.
