With the appearance of knock-off and counterfeit filters in the market, NMCL took strategic measures to develop authenticity verification holograms that were affixed on all Berkey®-branded filters. After a period of time, we discovered that not only had criminals copied our filters and packaging, but they were also copying our authentication holograms. We therefore began to add features to our holograms to help consumers distinguish between authentic and counterfeit filters, including verifiable serial numbers for which consumers could call our customer service department to verify if the Berkey® filters they purchased were genuine or fake.
In an effort to stay ahead of the illegal counterfeit activities impacting the Berkey® brand, we have had to make several iterations of holograms. Second-generation holograms are currently being used on all Berkey®-brand filters, and we will soon release a more advanced third-generation hologram with more advanced features.
