Quick verdict: ⚠️ New car smell is generally safe in small amounts, but it's best to limit exposure—especially in the first trimester. The "new car smell" comes from volatile organic compounds (VOCs) like formaldehyde and benzene, which can be harmful in high concentrations. Most experts agree that brief, occasional exposure (like driving a new car for short trips) is unlikely to pose a risk, but prolonged or intense exposure should be avoided. If you're concerned, ventilate your car well and consider safer alternatives.
You just slid into the driver’s seat of your shiny new car, took a deep breath, and—bam—there it is: that unmistakable "new car smell." For most people, it’s a sign of freshness, a little luxury. But if you’re pregnant, that same scent can trigger a wave of worry. Is new car smell safe during pregnancy? What if you’ve already been driving it for weeks? What if you’re planning a long road trip?
Take a breath. We’ve dug into the research, consulted obstetric guidelines, and talked to moms who’ve been there. Here’s what you need to know—without the panic. If you’ve already been exposed, don’t stress: the risks are low for most people. But if you’re looking for ways to reduce exposure or safer alternatives, we’ve got you covered too.
| Trimester | Verdict | Notes |
|---|---|---|
| First trimester | ⚠️ Limit exposure | This is the most sensitive period for fetal development. While brief exposure is unlikely to cause harm, avoid prolonged or intense exposure to new car smell, especially in poorly ventilated cars. |
| Second trimester | ✅ Generally safe | Risks decrease as organ development is mostly complete. Still, ventilate your car well and avoid sitting in a parked car with the windows closed. |
| Third trimester | ✅ Generally safe | Your baby is fully formed, but high VOC exposure could still cause discomfort like headaches or nausea. Keep air flowing, especially in hot weather. |
| Breastfeeding | ✅ Generally safe | VOCs are not known to pass into breast milk in significant amounts. However, if you feel unwell after exposure, take precautions to avoid passing symptoms to your baby. |
What is new car smell?
That "new car smell" isn’t just one thing—it’s a cocktail of chemicals released from materials like plastics, adhesives, upholstery, and dashboard components. These chemicals are called volatile organic compounds (VOCs), and they evaporate into the air at room temperature, creating that distinctive scent. The most common VOCs in new cars include:
- Formaldehyde: A preservative and adhesive found in many household products, known to irritate the eyes, nose, and throat.
- Benzene: A solvent used in plastics and synthetic fibers, classified as a carcinogen by the World Health Organization (WHO).
- Toluene: A solvent used in paints and coatings, which can cause dizziness and headaches in high concentrations.
- Acetone: A solvent found in some adhesives and cleaners, which can irritate the respiratory system.
- Ethylbenzene and xylene: Chemicals used in plastics and synthetic rubber, which can cause neurological symptoms like dizziness or confusion with prolonged exposure.
These chemicals aren’t added to cars to create a smell—they’re byproducts of the manufacturing process. Over time, they "off-gas" or release into the air, which is why new car smell fades after a few months. But while it’s there, it can be more than just an annoyance—especially for pregnant women.
Is new car smell safe during pregnancy?
The concern with new car smell comes from the VOCs it contains, particularly formaldehyde and benzene. Both are classified as teratogens—substances that can interfere with fetal development—though the risk depends on the level and duration of exposure. The Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA) note that high levels of VOC exposure can cause health issues like headaches, nausea, and respiratory irritation. For pregnant women, prolonged exposure to high levels of VOCs has been linked to a slightly increased risk of complications like low birth weight or preterm birth, though the evidence is not conclusive.
That said, the risk from typical new car smell exposure—like driving a new car for short periods—is low. The American College of Obstetricians and Gynecologists (ACOG) doesn’t have a specific guideline on new car smell, but their general advice on chemical exposure during pregnancy is to minimize it where possible. The UK’s National Health Service (NHS) echoes this, recommending that pregnant women avoid unnecessary exposure to chemicals, including those found in new cars.
So what does this mean for you? If you’re driving a new car occasionally, you’re likely fine. But if you’re spending hours in a new car every day—like for a long commute—it’s worth taking steps to reduce your exposure. We’ll cover how to do that later in this article.
Is it safe to smell new car fumes during first trimester?
The first trimester is the most critical window for fetal development. During these 12 weeks, your baby’s organs, brain, and nervous system are forming, and this is when they’re most vulnerable to external influences, including chemical exposure. So, is new car smell safe during pregnancy in the first trimester? The answer is a cautious "yes, but limit it."
While there’s no direct evidence that typical new car smell exposure causes birth defects, the VOCs in new car smell—like formaldehyde and benzene—have been linked to developmental issues in animal studies when exposure is high. Human studies are limited, but the World Health Organization (WHO) classifies benzene as a Group 1 carcinogen, meaning it’s known to cause cancer in humans. Formaldehyde is also classified as a probable human carcinogen. While the levels in new cars are much lower than in industrial settings, it’s still a good idea to minimize exposure during this sensitive time.
If you’re in your first trimester and driving a new car, here’s what you can do to reduce your risk:
- Ventilate your car: Roll down the windows or use the air conditioning to circulate fresh air, especially when the car is parked in the sun.
- Avoid sitting in a parked car: If your car has been sitting in the sun, the heat can increase VOC off-gassing. Open the doors and let it air out before getting in.
- Limit long drives: If you have a long commute, try to break it up or carpool with someone whose car isn’t new.
- Use an air purifier: Portable HEPA air purifiers designed for cars can help reduce VOC levels. We’ll cover safer alternatives in more detail later.
If you’re worried because you’ve already spent time in a new car during your first trimester, try not to stress. The risk from brief, occasional exposure is very low. Focus on reducing exposure moving forward, and talk to your provider if you have specific concerns.
How much new car smell exposure is dangerous while pregnant?
There’s no one-size-fits-all answer to how much new car smell is "safe" during pregnancy, but experts agree that prolonged or intense exposure should be avoided. Here’s what you need to know about safe exposure limits:
The EPA sets guidelines for indoor air quality, including limits for VOCs like formaldehyde and benzene. For formaldehyde, the EPA recommends keeping indoor levels below 0.1 parts per million (ppm) to avoid health effects. For benzene, the EPA’s limit is even lower: 0.005 ppm. In new cars, VOC levels can be significantly higher—sometimes up to 10 times the EPA’s recommended limits—especially in the first few months after manufacturing.
So what does this mean for you? If you’re driving a new car, here’s a rough guide to safe exposure:
- Short trips (under 30 minutes): Generally safe, especially if you ventilate the car by opening windows or using the air conditioning.
- Longer trips (30 minutes to 2 hours): Take breaks to get fresh air, and avoid driving in extreme heat, which can increase VOC off-gassing.
- Prolonged exposure (over 2 hours per day): Try to reduce your time in the car, or take steps to lower VOC levels (like using an air purifier or parking in the shade).
- Sleeping in a new car: Avoid it. VOC levels can build up overnight, especially in a closed space.
If you’re unsure about your exposure, pay attention to how you feel. Symptoms like headaches, dizziness, nausea, or eye/nose/throat irritation can be signs that VOC levels are too high. If you experience these symptoms, get fresh air immediately and consider talking to your provider.
What chemicals in new car smell are harmful during pregnancy?
The "new car smell" is a mix of chemicals, but a few stand out as particularly concerning during pregnancy. Here’s a breakdown of the most harmful VOCs in new cars and why they matter:
| Chemical | Where it’s found in cars | Risks during pregnancy | Safe exposure limit (EPA/WHO) |
|---|---|---|---|
| Formaldehyde | Adhesives, upholstery, dashboard materials | Irritates eyes, nose, and throat; linked to respiratory issues. High levels may increase risk of low birth weight or preterm birth. | 0.1 ppm (EPA) |
| Benzene | Plastics, synthetic fibers, paints | Classified as a Group 1 carcinogen by WHO. High exposure may increase risk of developmental issues or leukemia in offspring. | 0.005 ppm (EPA) |
| Toluene | Paints, coatings, adhesives | Can cause dizziness, headaches, and nausea. High exposure may affect fetal development, though evidence is limited. | 1 ppm (EPA) |
| Acetone | Adhesives, cleaners, some plastics | Irritates respiratory system; high levels may cause headaches or nausea. Not known to cause birth defects. | 26 ppm (EPA) |
| Ethylbenzene | Plastics, synthetic rubber | Can cause neurological symptoms like dizziness or confusion. Animal studies suggest potential developmental risks at high levels. | 1 ppm (EPA) |
It’s important to note that the levels of these chemicals in new cars are typically much lower than the EPA’s recommended limits. However, because they’re all present at once, the cumulative effect can be more significant—especially in a closed, unventilated space. Heat can also increase VOC off-gassing, so parking your car in the sun can make the smell (and the chemical levels) more intense.
If you’re concerned about VOC levels in your car, you can use an at-home VOC test kit to measure them. These kits are available online and can give you a sense of whether your car’s air quality is within safe limits. If levels are high, take steps to ventilate the car and reduce exposure.
Are there pregnancy-safe alternatives to new car smell air fresheners?
If you love that "new car" feeling but want to avoid the chemicals, you’re in luck. There are plenty of pregnancy-safe alternatives to new car smell that can keep your car smelling fresh without the VOCs. Here are some of the best options:
- Baking soda odor absorber: Place an open box of baking soda on the floor of your car or sprinkle it on carpets and upholstery. Baking soda naturally absorbs odors and is completely safe during pregnancy.
- Activated charcoal air purifier bags: These bags contain activated charcoal, which absorbs VOCs and odors. They’re non-toxic, reusable, and can last for months. Just place one in your car and replace it when it stops working.
- Essential oil diffusers (pregnancy-safe oils only): If you enjoy scents, use a car diffuser with pregnancy-safe essential oils like lavender, chamomile, or citrus. Avoid oils like rosemary, clary sage, or basil, which may not be safe during pregnancy. Always check with your provider before using essential oils.
- HEPA air purifier for cars: Portable HEPA air purifiers designed for cars can filter out VOCs, allergens, and other pollutants. Look for one with a carbon filter, which is especially effective at trapping VOCs.
- Fresh air ventilation: The simplest solution: roll down the windows or use the air conditioning to circulate fresh air. This dilutes VOCs and reduces their concentration in your car.
- Natural fiber car seat covers: If your car’s upholstery is a major source of VOCs, consider covering the seats with natural fiber covers made from cotton, linen, or wool. These materials don’t off-gas like synthetic fabrics.
- Beeswax-based car air fresheners: Beeswax air fresheners are a natural, non-toxic alternative to synthetic air fresheners. They release a subtle honey-like scent and can help neutralize odors.
- Houseplants (for parked cars): While you can’t keep a houseplant in a moving car, you can place one in your parked car if it’s safe to do so (e.g., in a garage). Plants like spider plants, peace lilies, and snake plants can help absorb VOCs. Just make sure the plant is secure and won’t become a hazard while driving.
If you’re looking for a quick fix, cleaning your car seats with pregnancy-safe products can also help reduce odors and VOCs. Just avoid harsh chemicals like bleach or ammonia, which can be harmful during pregnancy.
Which car brands have the least toxic new car smell?
If you’re in the market for a new car and want to minimize VOC exposure, some brands are better than others. While no car is completely free of new car smell, certain manufacturers have taken steps to reduce VOC levels in their vehicles. Here’s what you need to know:
The Toyota Prius
Volvo is another brand that’s made strides in reducing VOCs. The company has a Volvo Interior Air Quality System (IAQS), which filters out harmful chemicals and pollutants from the air. Volvo’s commitment to sustainability extends to its materials, and many of its cars use natural or recycled materials in the interior. Subaru has also been recognized for its efforts to reduce VOCs. The brand’s Subaru Global Platform includes a focus on interior air quality, and many of its models meet strict emissions standards. The Subaru Outback and Forester, in particular, have been praised for their low VOC levels. If you’re looking for a luxury option, Mercedes-Benz has introduced a range of vehicles with low-emission interiors. The brand’s EQ electric vehicles, for example, are designed with sustainable materials and low-VOC adhesives and paints. Mercedes also offers an optional air balance package, which includes an air purifier and fragrance system to improve interior air quality. For a more budget-friendly option, the Honda Fit has been noted for its relatively low VOC levels. Honda has also made efforts to reduce harmful chemicals in its vehicles, and many of its models meet strict emissions standards. If you’re unsure about a specific model, ask the dealer about its VOC levels or look for certifications like Greenguard or OEKO-TEX, which indicate that the car’s interior materials have been tested for harmful emissions. You can also check online reviews or forums to see what other owners say about the new car smell in a particular model. This is one of the biggest fears for pregnant women exposed to new car smell, and it’s understandable. The idea that something as common as a new car could harm your baby is terrifying. So, can new car smell cause miscarriage or birth defects? The short answer: the risk is very low for typical exposure, but high or prolonged exposure should be avoided. Let’s break down what the research says. The VOCs in new car smell, like formaldehyde and benzene, are classified as teratogens, meaning they can interfere with fetal development in high doses. Animal studies have shown that high levels of benzene exposure can cause developmental issues, and formaldehyde has been linked to low birth weight in some human studies. However, the levels of these chemicals in new cars are much lower than the doses used in these studies. The American College of Obstetricians and Gynecologists (ACOG) notes that while high levels of chemical exposure can increase the risk of complications like miscarriage or birth defects, the risk from typical new car smell exposure is minimal. The NHS echoes this, stating that brief exposure to chemicals like those in new car smell is unlikely to harm your baby. That said, it’s still a good idea to minimize exposure, especially during the first trimester when your baby’s organs are developing. If you’re concerned because you’ve spent a lot of time in a new car, try not to panic. The risk from occasional exposure is very low. Focus on reducing exposure moving forward, and talk to your provider if you have specific concerns. If you’re experiencing symptoms like headaches, dizziness, or nausea after exposure to new car smell, it’s a sign that VOC levels may be too high. Get fresh air immediately and consider taking steps to reduce VOCs in your car, like ventilating it or using an air purifier. If you have asthma, allergies, or other respiratory conditions, you might be more sensitive to the chemicals in new car smell. Is new car smell worse for pregnancy if you have asthma or allergies? The answer is yes—VOCs can trigger symptoms like coughing, wheezing, or shortness of breath, which can be uncomfortable or even dangerous during pregnancy. The VOCs in new car smell, like formaldehyde and toluene, are known to irritate the respiratory system. For people with asthma or allergies, this irritation can trigger an asthma attack or allergic reaction. The American Academy of Allergy, Asthma & Immunology (AAAAI) notes that VOC exposure can worsen asthma symptoms and recommends minimizing exposure to these chemicals, especially in enclosed spaces like cars. If you have asthma or allergies and are driving a new car, here’s what you can do to reduce your risk: If you experience symptoms like wheezing, coughing, or shortness of breath after exposure to new car smell, get fresh air immediately and use your inhaler if you have one. If symptoms persist, seek medical attention. If you’re pregnant and driving a new car, there are plenty of steps you can take to reduce your exposure to new car smell. Here’s a practical guide to keeping your car’s air as clean as possible: The simplest way to reduce VOC levels is to let fresh air in. Roll down the windows or use the air conditioning to circulate air, especially when the car is parked in the sun. If you’re driving, crack the windows to keep air flowing. This can help dilute VOCs and reduce their concentration in your car. Heat increases VOC off-gassing, so parking your car in the shade or using a sunshade can help keep VOC levels lower. If you don’t have access to shade, try to park in a garage or covered area. Portable HEPA air purifiers designed for cars can help filter out VOCs, allergens, and other pollutants. Look for one with a carbon filter, which is especially effective at trapping VOCs. Place the purifier on the dashboard or floor of your car and run it while you drive. If your car has been sitting in the sun, the heat can cause VOCs to off-gas more quickly. Before getting in, open the doors and let the car air out for a few minutes. This can help reduce VOC levels before you start driving. Regular cleaning can help reduce odors and VOCs in your car. Use pregnancy-safe cleaning products to wipe down surfaces like the dashboard, seats, and door panels. Avoid harsh chemicals like bleach or ammonia, which can be harmful during pregnancy. Place an open box of baking soda on the floor of your car or sprinkle it on carpets and upholstery. Baking soda naturally absorbs odors and is completely safe during pregnancy. You can also use activated charcoal air purifier bags, which absorb VOCs and odors. If you have a long commute, try to break it up or carpool with someone whose car isn’t new. This can help reduce your overall exposure to new car smell. If you’re concerned about VOC levels in your car, you can use an at-home VOC test kit to measure them. These kits are available online and can give you a sense of whether your car’s air quality is within safe limits. If levels are high, take steps to ventilate the car and reduce exposure. While the risk from typical new car smell exposure is low, it’s still important to be aware of the potential side effects and risks. Here’s what to watch for: Short-term exposure to new car smell can cause symptoms like: These symptoms are usually mild and go away once you get fresh air. If you experience them, ventilate your car immediately and take a break from driving if possible. Prolonged or high exposure to VOCs like formaldehyde and benzene has been linked to more serious health effects, including: For pregnant women, prolonged exposure to high levels of VOCs has been linked to a slightly increased risk of complications like: Again, the risk from typical new car smell exposure is minimal, but it’s still a good idea to minimize exposure where possible.
