Vesync Voluntarily Discontinues Certain Claims for HEPA Air Purifiers Following National Advertising Division Challenge by Dyson

New York, NY – August 15, 2023 – Following a BBB National Programs National Advertising Division (NAD) challenge, brought by competitor Dyson, Inc., Vesync Co., Ltd. voluntarily discontinued certain claims for its HEPA air purifiers.

Dyson challenged claims that Vesync’s Levoit EverestAir Smart True HEPA, Core 300, and Core 300S True HEPA air purifiers and their respective replacement filters have passed HEPA standards and argued that such claims conveyed other misleading messages.

In response to the challenge, Vesync asserted its belief in the efficacy of its products and stated that the challenged claims were made based on pre-existing independent third-party data. Vesync informed NAD that it was in the process of updating its testing data, however, and that for reasons unrelated to Dyson’s challenge, it had elected to permanently discontinue the challenged claims. Therefore, NAD did not review the claims on their merits.

In its advertiser statement, Vesync thanked NAD for its attention to the matter and stated that it “does not concede that there was anything misleading about the claims but has decided to voluntarily discontinue the claims.”
