 These things stay around for 18 months. So if you're one of those people that like likes to change your color in your house, like you change your shoes, you're in for a big chemical load just because you keep painting all the time. So it's important for people to realize, even though you're not smelling something anymore and necessarily that big impact that you smell in the first week is maybe gone and you don't have that anymore. That doesn't mean the chemicals aren't still there affecting you. So they stay around for a long time.
