The description says: "6 pcs. high-efficiency HEPA filters. With the flash I can see tiny pinholes through this filter, while with iRobot's new OEM filter I can't see pinholes! Other than that, the filter looks well made and fits my e5 Roomba very well! However, I am returning the item for the reason stated. I think what it says here is "You get what you pay for, that's fair", don't get me wrong, I'm not saying the product is bad, I'm just saying it's not what I expected!
