I have decided to pay extra for "genuine" iRobot replacement filters for my Roomba. Reviews of the cheaper versions said they either didn't fit, didn't work, or had some other defect. Look what I have: unmarked filters in bubble wrap. They seem to work, but how can you tell if they don't work? Have I ever measured the amount of debris that the original filters prevented from getting into my Roomba's mechanism? Of course not. I did not expect such a presentation when I ordered and paid for "real" filters. I suspect they are not real. I will no longer order from this seller.
