From the product page there seems to be some doubt as to whether this filter is a genuine OEM part. I bought it anyway. The freshly received filter (right) is not marked "Original". Sticker on the side, like my old one (left). But other than that, it looks and feels the same. (Weight, design, etc.) The old filter has been in my EUREKA THEBOSS SMARTVAC since I bought an upright a few years ago. For what it's worth and hope it helps.
