My filters were filled, sold by Value Sourcing and shipped to Amazon. I paid extra money to get decent branded replacement filters. I didn't realize I had received counterfeit filters until I ordered my clean allergy upgrade kit and compared the filters from my pet allergy kit and my original replacement filter. There is no doubt that these are quality replacements but they are nothing like the others, the filters are thinner/stiffer and more like plastic whereas the neat branded filters are more like a fiber mesh. I noticed that the filter is not filling. with dust just as much, but still works pretty well. I'm only giving 2 stars because I didn't get original Neato brand filters.
