Maureen, search https://www.sharkclean.com/ for part # XF1510. This should be a comparable part for this vacuum.
This may be too late for some but the OEM part number for the Shark V15Z vacuum is XF1510. If you Google 'Shark XF1510 vacuum filter' it will bring up available vendors that carry it still.
I need the same filter. please let me know if you find them Maureen my email is 4gordonfanns@?gmail.com. thank you.
Is there another filter that will fit the v15z
m
This filter will fit the V15Z models too
