1．Basic Knowledge of Ventilation
What is ventilation?
Ventilation is how we keep your air healthy. It works by swapping out old, trapped indoor air with fresh air from outside. This dilutes harmful particles and ensures the air you breathe is always clean and crisp.
What are Indoor Pollutants?
Think of pollutants as anything in your room’s air that shouldn't be there. While some are easy to see, like dust, others are invisible gases and germs that can affect your health.
Common indoor pollutants include:
- Gases: Carbon dioxide (CO2) from breathing, Carbon monoxide (CO) from heaters, and Formaldehyde (HCHO) from furniture or paints.
- Particles: Everyday house dust and seasonal pollen.
- Biologicals: Tiny bacteria and viruses that spread through the air.
Why is Ventilation Necessary?
1. To Flush Out Invisible Pollutants
In a room with closed windows and doors, the air has nowhere to go. This causes pollutants—like CO2 from breathing, dust, and germs—to stay trapped. Over time, these build up to levels that can make you feel tired, give you headaches, or impact your long-term health.
Ventilation acts as a "fresh air exchange," thinning out these pollutants and pushing them out of your home.
2. Modern Homes "Trap" Dirty Air
Today’s houses and apartments are built to be very airtight to save energy. While this is great for cooling, it means "dirty" air (moisture, odors, and chemicals from furniture) can't escape on its own. Without an active ventilation system, your home effectively becomes a sealed box where stale air just keeps piling up.
Key Simple Improvements:
-
Relatable Imagery: Used the "sealed box" analogy, which is much easier to visualize than "high level of airtightness."
-
Health Connection: Added specific symptoms like "feeling tired" or "headaches" so the user understands the personal benefit.
-
Action-Oriented: Changed "dilutes and displaces" to "flushes out" and "fresh air exchange."
2．Tips on Ventilation for Home
How to achieve proper airflow in your home.
1. Use Your 24-Hour Ventilation System Correctly
Most homes and apartments feature built-in air vents and 24-hour ventilation systems, yet many residents fail to operate them properly.
These vents sit within your walls and ceilings to manage airflow. When you run a ventilation fan in the bathroom or toilet, it actively pushes dirty indoor air outside. At the same time, the system draws fresh outdoor air inside through the vents. This common setup can completely refresh your room’s air within two hours. Using this existing system correctly is your first step toward a healthier home.
However, homeowners often close vents or turn off their 24-hour ventilation systems because they find the incoming outdoor air too cold or too hot. When you do this, you stop the system from doing its job, allowing dirty air to pile up inside your home. To keep your air clean, always leave your vents open and keep the 24-hour ventilation system running.
2. Open Windows to Create a Fresh Air Path
To keep your home healthy, aim to open your windows for about 5–10 minutes every hour.
Keep in mind that window size, room area, and the type of pollutants in your air all change how fast your home discharges stale air. Because these factors vary, you cannot easily measure the exact effectiveness or the specific reduction in disease risk.
However, you can boost results by ventilating more often. Two 5-minute sessions provide better airflow than one 10-minute session. Essentially, the more often you refresh the air, the better your results.
If you worry about pollen, place an air purifier near the open window to catch incoming particles. You can also use lace curtains to act as a simple, effective shield against outdoor allergens.
Creating an Efficient Air Passage
When you ventilate your home, always open two windows rather than just one. This creates a clear air passage that moves stale air out much faster. For maximum efficiency, choose windows that sit diagonally across from each other. This diagonal path forces air to flow across the entire room, ensuring no corner is left with stagnant air.
Create a superior air path by opening windows on opposite, diagonal walls.
Good Example: Diagonal window placement creates a superior air passage, forcing fresh air to sweep through the entire room
Placing two open windows too close together prevents air from flowing through the entire room.
Bad Example : Nearby windows only circulate air in a small area. By placing openings too close together, you stop fresh air from reaching the far corners of your room.
If you struggle to catch a breeze even with your windows open, use the "Narrow-to-Wide" technique to force air into the room.
Air naturally enters a space through small gaps with higher pressure and exits through larger openings with less resistance. To maximize this effect and pull in a stronger breeze, follow these active steps:
-
Narrow the Inlet: Open the "supply" window (where you want air to enter) only a small distance.
-
Widen the Outlet: Open the "exhaust" window (where air leaves) as wide as possible.
If a breeze won't enter your room naturally, force it in by narrowing the entry window and widening the exit window.
Ventilating a room with one window.
If your room has only one window, you must manually create an air path. Simply opening the window isn't enough; you need to "pull" the stale air out.
Follow these two active steps for the best results:
-
Open the Door: This creates a secondary opening for air to move through.
-
Point the Fan Outside: Place your fan near the window, but point it toward the outdoors.
Why this works: By pointing the fan toward the window, you actively "exhaust" or push the dirty indoor air out of the room. This creates a low-pressure area that naturally draws fresh air in through the open door. If you point the fan into the room, you only swirl the dirty air around, even if some fresh air enters.
For a room with only one window, place a fan toward the window to create a breeze.
For a room without a window
If a room has no windows, you can still refresh the air by opening the door and using a fan to push the air out of the space. To maximize this effect, follow these two active steps:
-
Clear the Room: Open the door and place a fan facing outward. This forces stagnant air into the hallway or common area.
-
Use Your Exhaust Fans: Run your bathroom, lavatory, or toilet ventilation fans simultaneously. These fans act as a "vacuum" for the entire home, pulling the air from the windowless room and discharging it outside.

Maximize Airflow with Your Kitchen Ventilation Fan
Your kitchen exhaust fan moves the largest volume of air in your home, making it your most powerful ventilation tool. To refresh your entire living space, follow these active steps:
-
Create a Long-Distance Air Path: Open a window located as far from the kitchen as possible. This forces the kitchen fan to pull fresh air through the entire house before discharging the stale air outside.
-
Boost Your Natural Ventilation: Even if you open two windows, always run the kitchen fan. It acts as a high-volume "engine" that accelerates the natural air exchange process.
-
Target Stagnant Air: By operating the kitchen fan alongside open windows, you ensure that fresh air reaches every corner, not just the area near the windows.
How to Ventilate Your Living Room Without Opening the Main Entrance
Open two windows facing the balcony.
No breeze will enter or leave when only one window is open, so be sure to open both ends to allow air to flow.
The balcony windows should be opened at two places (both ends).
If a breeze does not flow into the room even when the windows are open, operate the kitchen ventilation fan (for the range hood) and open the balcony window farthest away from the ventilation fan.
Operate the kitchen ventilation fan and partially open the window facing the balcony which is farthest away from the kitchen.
