Review on High-Quality EnviroCare Replacement Vacuum Filters for Shark Navigator Lift-Away NV350, NV351, NV352, NV355, NV356, NV356E, NV357 - Includes 2 Foam and 2 Felt Filters, Plus 1 Hepa Filter. Perfectly Replaces Shark Part #Xff350 & Xhf350 by Jessica Wang

The ones I received fit perfectly. Seems to get dirty quicker than the Shark brand. The thin filter is slightly thicker than the original. thick filter was identical mm. i suck a lot I was able to remove dirt stains better with this filter than with sharks and I'm not sure if that's a plus point of the product. I will buy again but I hope they make them soon. When I bought other filters they were unsuccessful for my other vacuums.
