The filter came quickly and fits perfectly. The article says it filters just like the OEM version; I can't comment on that as I don't have a test device. The paper element appears slightly lighter, so the perceived quality is lower. But after a week of use, I can see that the filter is catching the dirt that gets past my HEPA bag (I have the Sear HEPA bag), so it seems to be working fine. Since the price is 1/8 of the price. Sears the price it seems great!
