These filters were exactly the same as the ones in my Roman, and they worked perfectly. I'm unable to distinguish between the two.

These filters quickly become clogged - I'm not sure what they're made of compared to the iRobot brand, but we're now getting error messages telling us to empty the bin when it's not full, among other things. The filters from iRobot would last a long time, whereas these only last one or two uses before becoming too clogged. The brush that comes with the package appears to be useless. We can't clean the filters with a hand vacuum, as we could with the iRobot brand, so we'll have to go back to the very expensive filters. I don't want our iRobot to be ruined as a result of these.
In a small farm house with two large dogs, three indoor cats, and three humans, there is a lot of dirt, dander, and hair. When I empty the dirt cup, I tap out the excess and replace it once a week. They were made to go together. I probably replace them more frequently than I should, but it makes a significant difference in the suction.
So, it may not be a HEPA filter, but it does cause dirt to collect in the back of the bin, as opposed to the original filters, which seemed to either collect a little in the center or get jammed in the chute, triggering the "bin full" alert when the bin wasn't even close to being full. They're a little tighter than the originals, but they're holding up well so far. Given the price, I'm not opposed to changing them out more frequently.
These are identical to the Roomba filters in appearance and performance. It was a perfect match for my e-series. I have a dog and a cat, so I'm always changing these out, so this is a much more cost-effective option. Shipping was quick, and I've had no issues thus far.
Filters are exactly the same as the originals. My neighborhood is very dusty and dry. After each use, the filter can be tapped clean outside on a deck railing or concrete walk to shake out the majority of the dust; I use each one for several weeks, but I do tap or blow out as much dust as possible.
I've tried cleaning the filters after dumping the bin, and I've also tried washing them when they got really bad. That, however, has never been a successful strategy. I was able to change them out frequently because they were inexpensive.
Perfect fit for the machine, and a fraction of the cost of the iRobot version. It also comes with a handy brush that can be used to clean between the ridges of the filters, extending their life.
