Review on 🔍 Colorfullife Filters: Enhance Your Cleaning with Shark Rotator DuoClean Powered Lift Away Speed Vacuum NV680, NV681, NV682, NV683, NV800, NV801, NV803, UV810 - Replace XHF680 and XFF680 Parts! by Brandon Wong

This listing comes up when searching for Shark NV611 filters but they don't fit. The foam filter is short, the felt pad is slightly larger. The HEPA cartridge is the correct height and width, but has a different curvature and is 1/4 inch smaller. According to the dimensions of this company's replacement filters, they do not offer an exact match. You can install them and the vacuum cleaner will work. Unfortunately, HEPA will have leaks. I can return them, but I may have to keep them until I find one that fits.
