US manufacturer RCI Technologies’ fuel purifiers have been recertified by the Green Clean Institute, an independent third-party organisation that reviews, researches and certifies various industrial services for their green credibility.

The Green Clean Institute researched the claims and properties of RCI’s purifiers, conducted a green audit, surveyed customers and reviewed numerous test results before granting the Green Clean certification.
The company says that this certification confirms the purifiers’ environmental benefits, something that appeals to RCI’s more eco-conscious customers. RCI’s fuel purifiers first received Green Clean Institute certification in 2008.
