I didn't know that Shark makes two different sized HEPA filters for my nv480?๐ฌ Now I know, only after I ordered the wrong size! Had to do a bit of research before I knew why what I ordered didn't fit! Send it back for a refund to turn around and order the correct size 2.36 and not 2.75! Know the size you need and save time and hassle. Foam and felt filters are EXCELLENT ๐๐ Fit and quality is great ๐๐ The only thing the seller needs to pay more attention to is that HEPA FILTERS COME IN TWO SIZES! 2.36 and 2.75!
