This is a BRITA pitcher water filter, the Liquelli MAXTRA Pro. I've used it for about two months, but I'm selling it now because I don't need it anymore. It's mostly in good condition, but there's a slightly cloudy area on the surface of the bottom on one side, as if it's been rubbed. I couldn't capture it well in the photos, so I haven't included a picture. Please be aware of this. Thank you.
