Set of 3 dust cut filters for iRobot Roomba. - Model: Roomba - Number of filters: 3 - Compatible models: iRobot Roomba series - Part number: 4651374 - Part type: Dust cut filter Thank you for viewing. I purchased these at K's Denki, but I mistakenly bought the wrong ones that don't fit my Roomba. They are new and unused, but the package has been opened once. Due to the thickness for shipping, I plan to take the contents out and flatten them for shipping. I will also fold the box and ship it together.
