I painted a room in my house just last week.
You definitely want the 99% VOC free paint (I am in Aus, we used Haymes brand paint)- I am actually extremely amazed at just how little it smelled and how fast the air was back to being no smell at all. Felt kinda silly for spending so much time setting up fans and barriers to stop the fumes getting into my birds room- last time I painted (approx 6-7 years ago) I recall the paint fumes being so overwhelming and hanging around for ages as well as penetrating every room of the house.
