This is a great and affordable replacement for the filters that came with Roomba. They look the same, fit perfectly and seem to be holding up. I clean mine with an old dry toothbrush after each use. I empty the dust bin, take out the filter, hold it over the trash can, and sweep the fine particles into the trash. I put the filter back in the dust box and put it back in the Roomba ready for the next cleaning. I have 4 dogs and am happy with the performance and durability of these replacement…
