Review on 🔍 High-Quality Replacement Filter Set for GreenVacShop 4+2 Pack Shark Rotator Professional Lift-Away NV500, NV501, NV502, NV503, NV505, NV510, NV520, NV552, UV560 – 4 Foam, 4 Felt, 2 HEPA Filters: XFF500 XHF500 by Marcos Woody

I liked that they were exactly the same as the ones that came with my vacuum but then I looked at various sellers here on Amazon and found them , that for less money I could have gotten a few more filters, and then I got annoyed that I didn't check the number of items more carefully. I have no idea if the quality is the same as other sellers who offer you double and triple for less money but I will definitely try one of these next time. But for this seller I can tell you that this filter system is perfect for my Shark v501 and still looks the same. I've washed the ones that came with the shark a few times, they dry well and are just as good until they get dirty again. The fit is spot on and maybe for the money and less I got a better hepa filtration system, hopefully they are thicker and better quality. I'll definitely let you know after using them for a while
