I don't know what to think so just wanted to share my thoughts. I've ordered these filters twice from Amazon but I think it's a third party and not Revain. I might be wrong. When I received the filters they came in an unsealed box with 3 filters and an instruction booklet. The battery that was supposed to be included wasn't included, but I didn't care. I wasn't happy that there were no covers on the filters, no gaskets and the water wasn't that tasty. In other words, you could not tell if they were really new filters. This time I ordered the filters from the Brondell website - not only were the filters individually wrapped, but the box was sealed. It had all the content and I can feel the difference when I drink water. Now I'm sure the filters weren't new.
