In the United States the National Advertising Division (NAD) of the Council of Better Business Bureau has investigated a number of advertising claims made by the Tennant Company relating to its ec-H2O technology. The NAD is responsible for reviewing national advertising for truthfulness and accuracy and is in place to foster public confidence in the credibility of advertising.
The NAD’s investigation found that Tennant’s claims could not to be adequately borne out by the tests that they presented. They include, especially, the Tennant slogans:
- ecH2O electronically converts water into a superior cleaning solution
- ecH2O outperforms [many] conventional chemicals
The NAD also welcomed the fact that the Tennant Company is no longer using the slogan:
- ecH2O technology makes water perform like a powerful detergent.
The cleaning equipment manufacturer Nilfisk-Advance submitted Tennant’s advertising claims to the NAD. Nilfisk-Advance reported on the NAD’s findings in a Press release.
Kärcher too is currently engaged in legal proceedings against Tennant’s British and German subsidiaries in connection with similar advertising claims for the ec-H2O technology and has taken its case to the UK Advertising Standards Authority and the Stuttgart District Court.
