These Hongfa Botvac D filters look impressive and can actually do the job well, but their quality control makes them disposable. Two of the first three of them I used had a tab that you press to remove the filter (so you can clean it) that snapped and broke. This will render the filter useless as you will not be able to put it back into Neato. I've never had any other filters, whether OEM or other 3rd party, with the same issues. I may have come across a poor quality batch, but they are too expensive for one-time use.
