We buy filtered milk and it rarely goes off, though we do go through it fairly quickly. Even so, it will last a few days (4+) once opened.
I buy this filtered milk too, and find that it lasts for ages. I used to get milk from the milkman but I think that it spends too long unchilled whilst they're delivering it and it was sometimes barely cold by the time I could take it inside.
As an aside, I keep my bread in the bottom salad drawer of my fancy German fridge which is only just above freezing and is humidified. It does get slightly firmer, but since we toast it anyway this doesn't matter to me.
