Have you ever walked into your home and been greeted by the savory aroma of your neighbor’s cooking? Or perhaps you’ve been cooking up a storm in your own kitchen, only to have your neighbor knock on the door and ask what smells so good? If so, you’re not alone. The phenomenon of smelling your neighbors’ cooking is more common than you might think, and it’s all due to the way that smells travel through the air.
The Science of Smell
To understand how smells can travel from one apartment to another, it’s helpful to know a bit about the science of smell. Smells are made up of tiny molecules that are released into the air by various substances, such as food, cleaning products, and perfumes. These molecules are called odorants, and they’re able to travel through the air because they’re so small.
When we smell something, it’s because the odorant molecules have traveled up our nostrils and bound to specialized receptors on the surface of our olfactory epithelium, which is the mucous membrane lining the inside of our noses. This binding process triggers a signal that’s sent to our brain, which interprets the signal as a specific smell.
How Smells Travel Through the Air
So, how do smells travel from one apartment to another? There are a few different ways that this can happen:
- Air currents: When you cook or use a cleaning product, the odorant molecules are released into the air and can travel on air currents to other parts of the building. This is especially true in buildings with shared ventilation systems, where the air is circulated from one apartment to another.
- Ductwork: If you live in a building with a shared ductwork system, it’s possible for smells to travel from one apartment to another through the ducts. This is especially true if the ducts are not properly sealed or if there are gaps in the system.
- Shared walls: If you live in an apartment with shared walls, it’s possible for smells to travel through the walls and into your neighbor’s apartment. This is especially true if the walls are not well-insulated or if there are gaps in the walls.
Factors That Affect the Spread of Smells
There are several factors that can affect the spread of smells from one apartment to another. Some of the most significant factors include:
- Proximity: The closer you are to the source of the smell, the more likely you are to smell it. This is because the odorant molecules have less distance to travel, and are therefore more concentrated.
- Ventilation: If the building has a good ventilation system, it can help to reduce the spread of smells from one apartment to another. This is because the ventilation system can help to remove the odorant molecules from the air and replace them with fresh air.
- Insulation: If the walls and floors of the building are well-insulated, it can help to reduce the spread of smells from one apartment to another. This is because the insulation can help to block the odorant molecules from traveling through the walls and floors.
Types of Smells That Are Most Likely to Travel
Some types of smells are more likely to travel from one apartment to another than others. Some of the most common types of smells that can travel include:
- Cooking smells: Cooking smells are some of the most common types of smells that can travel from one apartment to another. This is because cooking often involves the use of strong-smelling ingredients, such as onions and garlic.
- Cleaning product smells: Cleaning products can also release strong-smelling chemicals into the air, which can travel from one apartment to another.
- Pet smells: If you have pets, you may notice that their smells can travel from one apartment to another. This is because pets can release strong-smelling dander and urine into the air.
What You Can Do to Reduce the Spread of Smells
If you’re finding that smells are traveling from one apartment to another, there are several things you can do to reduce the spread of smells:
- Use a ventilation system: If you have a ventilation system in your building, make sure to use it regularly to help remove odorant molecules from the air.
- Use insulation: If you’re finding that smells are traveling through the walls or floors, consider using insulation to block the odorant molecules.
- Use odor-absorbing products: There are a variety of products available that can help to absorb and neutralize odors. These products can be especially helpful if you’re finding that smells are traveling from one apartment to another.
DIY Solutions for Reducing Smells
If you’re looking for DIY solutions for reducing smells, there are several options you can try:
- Baking soda: Baking soda is a natural odor absorber, and can be used to neutralize smells in the air. Simply place an open box of baking soda in the area where the smell is strongest, and let it sit for a few hours.
- Activated charcoal: Activated charcoal is another natural odor absorber, and can be used to neutralize smells in the air. Simply place an open bag of activated charcoal in the area where the smell is strongest, and let it sit for a few hours.

What causes smells to travel between apartments?
Smells can travel between apartments through various means, including shared ventilation systems, gaps and cracks in walls and floors, and even through open windows. When your neighbor cooks, the smells from their food can rise into the air and travel through these pathways, eventually making their way into your apartment. This is especially true in buildings with shared ventilation systems, where the same air is circulated throughout the building.
In addition to these physical pathways, smells can also travel through the air itself. When molecules of a substance, such as food, are released into the air, they can travel long distances and be detected by the human nose. This is why you may be able to smell your neighbor’s cooking even if you don’t share a ventilation system or have any obvious gaps in your walls.
Why do some smells seem to travel farther than others?
Some smells seem to travel farther than others because of the unique properties of the molecules that make up those smells. For example, smells that are made up of smaller, lighter molecules can travel farther and faster than smells made up of larger, heavier molecules. This is why smells like smoke and gasoline can travel long distances, while smells like perfume and cooking odors may not travel as far.
The type of smell also plays a role in how far it can travel. Smells that are high in sulfur, such as the smell of garlic or onions, can travel farther than smells that are low in sulfur, such as the smell of vanilla or baking. This is because sulfur molecules are highly volatile and can travel long distances through the air.
Can smells travel through walls and floors?
Yes, smells can travel through walls and floors, especially if there are gaps or cracks in the building materials. When a smell is released into the air, the molecules that make up that smell can seep through tiny openings and travel through the walls and floors of a building. This is why you may be able to smell your neighbor’s cooking even if you don’t share a ventilation system or have any obvious gaps in your walls.
In addition to gaps and cracks, smells can also travel through the building materials themselves. For example, smells can travel through drywall and plywood, which are common building materials used in many apartments. This is because these materials are porous and can absorb and release molecules of a smell over time.
How can I reduce the amount of smells that enter my apartment?
There are several ways to reduce the amount of smells that enter your apartment, including using air purifiers, sealing gaps and cracks in walls and floors, and using odor-absorbing materials. Air purifiers can help remove molecules of a smell from the air, reducing the amount of smell that enters your apartment. Sealing gaps and cracks in walls and floors can help prevent smells from entering your apartment in the first place.
Using odor-absorbing materials, such as baking soda or activated charcoal, can also help reduce the amount of smells that enter your apartment. These materials can absorb molecules of a smell, reducing the amount of smell that is present in the air. You can place these materials in areas where smells tend to enter your apartment, such as near vents or in closets.
Can I talk to my neighbor about the smells?
Yes, you can talk to your neighbor about the smells. If you are being bothered by smells from your neighbor’s cooking, it’s a good idea to approach the situation in a friendly and respectful manner. You might say something like, “Hey, I wanted to talk to you about the smells that have been coming from your apartment. I know you like to cook, but the smells have been bothering me. Would you mind taking some steps to reduce the amount of smells that enter my apartment?”
It’s also a good idea to be open to finding a solution that works for both you and your neighbor. For example, you might suggest that your neighbor use a ventilation fan while cooking, or that they cook at times when you are not home. By working together, you and your neighbor can find a solution that works for both of you.
Are there any laws that govern smells in apartments?
Yes, there are laws that govern smells in apartments. In many places, there are laws that prohibit excessive noise and nuisance, including smells. If you are being bothered by smells from your neighbor’s apartment and you have talked to your neighbor about the issue but it persists, you may want to contact your landlord or local authorities to report the problem.
In addition to laws that govern noise and nuisance, there may also be laws that govern indoor air quality. For example, some places have laws that require landlords to provide a certain level of ventilation in apartments, which can help reduce the amount of smells that enter an apartment. If you are concerned about the smells in your apartment, you may want to research the laws in your area to see if there are any protections in place.
Can smells affect my health?
Yes, smells can affect your health. Some smells, such as those from mold or mildew, can trigger allergic reactions or respiratory problems. Other smells, such as those from chemicals or cleaning products, can cause headaches or other health problems. If you are concerned about the smells in your apartment and how they may be affecting your health, you may want to talk to a doctor or other healthcare professional.
In addition to triggering health problems, smells can also affect your mental health. For example, if you are constantly being bothered by smells from your neighbor’s apartment, it can cause stress and anxiety. If you are experiencing health problems that you think may be related to smells in your apartment, it’s a good idea to talk to a healthcare professional to get their advice.
