I don't think this is new. And the word pur is not on the blue cartridge. My machine has a green light when you put in a new cartridge and flashes red when it's bad and then no light at all when it's time to replace it. I put this replacement in my block and the light doesn't turn green. I don't burn at all. So I don't think it's a good product. I ordered three boxes. I got two today and the other is coming tomorrow. I will have to return the two unopened ones.
