C-POLAR and NanoFlashing™ questions, with the company’s answers and the sources they come from.
Last reviewed: .
What hydraulic performance evidence applies to the exact water-contact configuration under consideration?
The company names no hydraulic, migration, fouling or compatibility record for a water configuration.
Each record named on the Validation page covers the article it tested, and a result belongs to that article.
The Terms of Use state that, as of their effective date, the Water chapter describes a Research Application, and that it does not describe a finished product currently available from C-POLAR for that use. The Water page states that the NanoFlashing™ Water Filter has a permanent positive polarity, a fixed positive charge.
