I bought this kit as a good value filter kit for my Shark Rotator Powered Lift Away (I have an NV 752 and love it!). Conclusion: YES, they are perfect for a vacuum cleaner. No play, rattling and other things. The disc is a bit thinner than what Shark sells, but I don't think checking the filters for clogging and cleaning them regularly will make a noticeable difference. Here's a tip: always have a spare set on hand. or two of them. You need to clean the filters from time to time and they need time to dry. So if you have an extra set, you can use one set while the other dries.
