Review on 💧 Enhance Water Quality with Elkay 51300C WaterSentry Replacement Fillers by Gabriel Rosenberg

Bought three packs on March 19th. Return time expired, Amazon contacted Elkay. Elkay emailed me, I called 800. The problem is explained with a filter that does not reset the green LED, but immediately switches it to red. I was lucky that there were two filters left out of three packs. I tried the last filter, the LED turned green. After Elkay confirmed I had the blue and white sticker, they offered to ship a replacement free of charge. They only ask that the faulty one be sent back at their expense. This was the third filter change on this unit. There were no such problems before. The peeling white sticker on the old filter is an RFID sticker (?)
