Set of 2 circular filters for humidifiers. New, unused. I am selling the filters for permeating aroma oil because the humidifier unit stopped working. The items to be mailed are the two filters in the first photo. If you would like three filters, I can send one more from the filters in the second photo, so please comment if you would like that. Thank you very much. m(._.)m - Quantity: 2 filters - Shape: Circular Thank you for looking.
