What is a one-sentence summary of the following article?
If the room has been painted and the windows aren’t open, that paint smell is going to linger for a much longer time. Crack the windows as wide as you can to start introducing more air into the room. For many people, opening the windows makes the smell disappear after a day or so.  If it’s cold outside, open the windows 1–2 inches (2.5–5.1 cm) and turn your heat on. You may spend more on heating while the windows are open, but the cold air will really help with circulation in the room. If your windows don’t budge when you try to lift them, it could mean that they’re locked. Check the top of the window pane for 1-2 latches. Flip them and then try to move the window again. Get some standing or box fans and put them in the corners of the room. Point each fan towards an open window and set the fans on their highest setting. Let them run continuously.  If you don’t have any windows in a room that you’ve painted, open the windows in the nearby rooms and point fans in the windowless room towards the door. Put more fans in the hallway that point towards open windows in other rooms. Using a fan’s oscillating function is probably a bad idea. The goal is to create a closed system that sends air outside, not all over the room. A ceiling fan will help though because it aids ventilation all over the room at once. If you have fewer than 3 fans, prioritize the corners furthest away from the windows. If you have central air, turn the air conditioning on. Turn any fan settings up to high and let the air conditioning system run. Pumping new air into your home will help push out the paint odors. If you don’t want the air conditioning on, you can always flip the fan on but leave the air off if you have central air. If you only painted one or two rooms, closing the room’s door will isolate the paint odors. It will also help the air flow out the window since it won’t have anywhere else to go. Keep the windows open and the doors closed to help speed up the odor-removal process. Put a towel on the ground if there’s a gap between a closed door and the floor to keep the smell from trickling under the door.

Summary:
Open the windows in a room to bring new air in. Place fans in corners of the room and point them towards the windows. Turn your air conditioning on to increase ventilation. Close the door if you only painted one room and it has windows.
