I have an NV755 and these filters fit great. My old Shark filters turned yellow and didn't work well. They have improved the suction power, but after a few months they are already yellowing. I wash them in the sink with dish soap once a week. The felt filter seems thicker and more difficult to clean. I would buy them again.
