Quick answer
If your apartment smells like paint, the fumes come from solvents drying in the paint, and they fade as fresh air replaces them. Open windows on two sides, put a fan in one window blowing out, and give it time. Water-based paint smell usually fades in a few days to a couple of weeks. A carbon-filter air purifier is an optional helper if you cannot open windows or the smell hangs on.
Free fix vs. permanent fix
Cross-ventilate and wait
- Open windows on two sides so air flows through
- Point a box fan out of a window to push fumes outdoors
- Keep doors to unpainted rooms closed
- Keep flames, sparks and space heaters away from strong fumes
How long it lasts: Fixes it for good. Fresh air removes the fumes, and the smell fades as the paint cures. It is slow in cold or humid weather, or when windows stay shut.
An air purifier with a thick carbon filter
Activated carbon traps many odor gases that a dust filter lets through. It helps when windows must stay shut or fumes linger, but it does not replace fresh air. Look for a thick carbon bed, not a thin sheet.
What to get: Air purifier with a thick activated carbon filter
How long it lasts: As long as the carbon is not used up. Replace the filter on the maker's schedule.

Why it happens
Solvents drying in the paint
Paint gives off volatile organic compounds, known as VOCs, while it dries. Oil-based paint, primer and sealer give off more and for longer than water-based latex.
Poor airflow in a small space
Apartments have fewer windows and often no cross-breeze. The fumes stay in the air and soak into carpet, fabric and drywall, so the smell lingers.
Cold or damp weather
Paint cures slowly when the air is cold or humid, so it keeps releasing fumes for longer.
Another source nearby
A neighbor's paint job, new floor finish, glue or nail products can bring the smell in through shared vents and gaps around pipes.

Do these in order, starting with the simplest.
-
Open two windows on opposite sides
Cross-ventilation moves far more air than one open window. Open them as wide as is safe and keep them open through the day.
-
Put a fan in a window blowing out
Tool used: Box fanSet a box fan in one window facing outdoors so it pushes fumes out, and keep a window open on the other side so fresh air comes in. Run it for several hours at a time.
-
Keep flames and sparks away
Some paints, thinners and finishes give off vapors that can ignite. No candles, no smoking, and keep gas appliances and space heaters off while the smell is strong.
-
Stay out of the room if you can
Spend the first day elsewhere. Babies, pregnant people, pets and anyone with asthma should stay out longer. Headache, dizziness or nausea means get fresh air right away.
-
Add a carbon-filter purifier for what is left
Tool used: Air purifier with a carbon filterIf windows must stay shut or a smell lingers after a few days, run the purifier on high in the room with the smell, with the door closed. Check the filter's life, since a used-up carbon filter stops working.

When free fixes aren't enough
If you have aired the apartment for a week and the smell is still strong, the paint may be oil-based, laid on thick, or sealed in a closet, or the fumes may be coming from somewhere else. A purifier with a thick carbon filter helps in rooms where you cannot get a breeze, like a bedroom with one window. It is a helper, not a cure. If you have a headache, nausea, dizziness, burning eyes or trouble breathing, leave and get fresh air, and call a poison control center (1-800-222-1222 in the US). If nobody has painted and you cannot find the source, ask your landlord or building manager.

Apartment smells like nail polish or acetone? Check these first
- An open nail polish remover bottle or spilled polish on a vanity
- Paint thinner, lacquer or glue left uncapped in a closet or under a sink
- New furniture, flooring or a floor refinish nearby
- A neighbor's project, with fumes coming through a shared vent
The paint type decides how long you wait
Water-based latex paint dries fastest and smells for the shortest time. Oil-based paint, primers and sealers take longer and give off more fumes. Thick coats and closed-up rooms stretch it out. If you are painting yourself, choose a low-VOC paint and plan for open windows for the first few days.
What to skip
Candles, sprays and ozone generators
Candles and plug-in fresheners add their own fumes on top and remove nothing. Bowls of vinegar, onion or baking soda do little against solvent fumes. Skip ozone generators sold as odor removers too, since ozone irritates your lungs. Fresh air does the real work.
