This is the second Brita mantra + water filter, I bought my first one in 2018 which wasn’t cheap but I liked the new features, but after about a week the LED light was constantly flashing red it wouldn’t stop,so I took it back to my local supermarket and exchanged it for the same model, but this time the LED doesn’t do anything it’s dead, I’m thinking of taking it back and getting a different model, very disappointing
