I've been using Brita filters for a long time but this time they didn't work properly. I bought two packs and installed the first filter on March 22, 2020. Their insert says it filters water for an average of 4 months. I'm a single woman so expect at least that much time. I noticed yesterday that the flashing light does not flash green and never flashes other colors. I pulled out another new filter, put it in and ran cold water for 5 minutes. no blinking Another point: Revain's return policy lists a May deadline. It can't be true if there are two cartridges that last four months each. I would only use a second cartridge four months after the deadline. I hope this is clear to you. I want refunds or new filters. Connie Thomas
