New York, NY, Oct. 01, 2025 (GLOBE NEWSWIRE) -- Following a challenge submitted by competitor Vesync US Corporation (d/b/a Levoit), BBB National Programs’ National Advertising Division will refer Shenzhen Rencongzhong Information Technology Co., Ltd. (d/b/a DKSports) to the Federal Trade Commission (FTC) for review and possible enforcement action for failure to submit a substantive response to the National Advertising Division’s (NAD) inquiry.

At issue for NAD were challenged express and implied claims that DKSports’ air purifier replacement filter products are compliant with HEPA standards and have comparable or superior performance to filters manufactured by Levoit.

Despite numerous outreach attempts, DKSports failed to respond to NAD’s inquiry and substantiate its claims. Therefore, NAD will refer the matter to the appropriate government agency, in this case the FTC, and to the platforms on which DKSports’ advertising appeared and NAD has a reporting relationship.
