These filters are very good. The price is a bit high, but the performance of the filters easily makes up for it. I change these things every 6 months as recommended and vacuum the filters once a week. This takes about 3 minutes and seems to prolong the life of the filters so after 6 months they are still performing at about the same level as new. I vacuum three times a week, so sometimes when I empty the bin, I just take the filter out and put it back in. I used the original Neato filters when I had the original Neato when it first came out and I can tell you that these filters absorb a lot more material than the previous ones. Definitely worth the money compared to older filters.
