Review on Enhance Performance with ConPus Replacement Filters for Rotator Lift Away by Jessica Martin

I have 2 Sharks and they use different filters. I bought a set of Shark filters and it didn't fit any of them. So I tried this one and the thin filter fits my NV752 but the big filter doesn't. So now I'm going to try a different set of filters specifically for my NV752. I also have a new Shark Vortex that even works with a different set of filters so there are at least 4 different types of Shark posts so check the model numbers before ordering! Rating for quality and price.
