Hi Bruce,Thank you for bringing this to our attention and for taking the time to share your concerns about the Shark NeverChange Air Purifier HP305. We want to assure you that the HP305 is indeed a genuine Shark model, manufactured and distributed through select retail partners, including Sam’s Club.From time to time, we produce specific models that are exclusive to certain retailers, which may not appear on our main website alongside other general-market models like the HP302. We hope this helps clarify, but if you have any further questions or would like assistance with the product, our team would be happy to help at 1-855-427-5127.Kind regards, Shark Clean
