Review on Neutop Replacement Parts for iRobot Roomba 800 900 Series: Roller Brush Sets, Hepa Filters, Side Brushes, and Screws by Alicia Evans

Update: So I open my mouth and put my foot in it. After buying OEM filters I had the same problem (filters get dirty after only 1-3 minutes). I've removed the rollers and cleaned out all the junk, tested both the OEM filter and these filters and can't tell the difference as they both work fine. In fact, these filters have a mesh screen over the filter pleats that keeps dirt from clogging them. First the good part, they fit well if a bit tight with the lid. The quality is so-so. Some filters have a different weave, some don't. Now for the bad. My vacuum only runs for 60 seconds or less before the 'bin full' message appears. which I think means the airflow through the paper filter is not the same as the original filters, which is why the vacuum cleaner thinks it's dirty. When the vacuum cleaner returns to the charging station, it simply warns that the bin is full, even though it is clean and fitted with a new fake filter. Throw them away and spend money on originals. Some people seem to have luck with them, but we don't.
