Have you ever wondered if the air inside your home is clean and safe to breathe? Indoor air quality is all about how clean or dirty the air is in places like your house, school, or workplace. Since we spend most of our time indoors, it is very important that the air we breathe is healthy.
Here, we will explain what indoor air quality means, what makes air good or poor, and how you can help make the air inside better.
What Makes Indoor Air Good?
1. Fresh Air
Good air comes from letting in clean air from outside through ventilation. This fresh air pushes out the stale, polluted air, like replacing old water with new water in a jar.
2. Low Pollution
Clean air has very little dust, smoke, or chemicals. The fewer these particles, the healthier the air is.
3. Balanced Humidity and Temperature
The air shouldn’t be too wet or too dry. Keeping humidity between 40% and 60% helps prevent mold and keeps you comfortable.
4. Effective Filters
Machines like HVAC systems use filters (such as HEPA filters) to catch tiny particles, ensuring the air stays clean and safe to breathe.
What Makes Indoor Air Poor?
Poor indoor air quality happens when one or more of these important parts are missing or not working well. Here are some reasons why the air might be bad:
1. Not Enough Fresh Air
If the building does not let in enough fresh air, the same air keeps moving around, and pollutants start to build up. Imagine if you were in a room with no windows; after a while, the air would feel stale and heavy.
2. Too Many Pollutants
There are many sources of indoor pollution. Some common ones are:
- Cooking: When you cook, especially on a gas stove, it can release smoke and gases.
- Cleaning Products: Some sprays and cleaners have chemicals called VOCs (volatile organic compounds) that can make the air smell bad and hurt your lungs.
- New Furniture or Paint: New items sometimes give off chemicals, a process called off-gassing.
- Smoking: Cigarette smoke has lots of chemicals that are very harmful.
- Dust and Pollen: Dust from carpets and pollen that comes in from outside can also make the air dirty.
3. Wrong Humidity and Temperature
If a room is too damp, it can lead to mold growth, which is harmful to breathe in. If it is too dry, it might irritate your eyes and throat. Both situations can make the air less comfortable to breathe.
4. Poor Maintenance
When machines like the HVAC system are not cleaned or checked often, they can start to spread dirt and dust around the building. Dirty filters or leaky ducts can turn a clean system into a source of pollution.

How Do We Make Indoor Air Quality Better?
The good news is that there are many ways to improve the air inside our homes, schools, and other buildings. Here are some ideas:
Increase Ventilation
- Open Windows: When the weather is nice, open windows for a few minutes. This is called “lüften” in German. It means to let fresh air in and push old air out. In summer, try opening windows twice a day for about 30 minutes. In winter, even 5 to 10 minutes can help!
- Fans and Vents: Make sure your room or building has fans that help move air around. Use exhaust fans in the kitchen and bathroom to remove steam and odors.

Use Air Purifiers
- HEPA Filters: Air purifiers with HEPA filters can catch many tiny particles, like dust and pollen, making the air cleaner.
- Regular Cleaning: Vacuum with a HEPA filter vacuum cleaner. This stops dust from just blowing back into the air.
Control Humidity
- Use a Dehumidifier: If your home is very humid, a dehumidifier can help take the extra moisture out of the air.
- Proper Heating and Cooling: Keeping your home at a comfortable temperature can help control humidity. Ideally, indoor humidity should be between 40% and 60%.
Choose Safe Products
- Low-VOC Products: When buying new furniture, paint, or cleaning products, look for items that have low VOC emissions. This means they give off fewer harmful chemicals.
- Fragrance-Free Options: Sometimes, products with strong scents can cause breathing problems. Choosing fragrance-free items can make the air cleaner.
Regular Maintenance
- HVAC Service: Have your heating and cooling systems checked and cleaned regularly. Change the filters as the manufacturer recommends.
- Duct Cleaning: Dust and dirt can build up in air ducts. Cleaning them helps keep the air moving freely and safely.
Keep Indoor Spaces Clean
- Dust and Vacuum: Regular cleaning helps remove dust, pet dander, and pollen that might be floating in the air.
- Wash Fabrics: Curtains, cushions, and rugs can collect dust. Washing them often can improve indoor air quality.

Interesting Facts About Indoor Air Quality
1. You Spend Most of Your Time Indoors
Did you know that most people spend about 90% of their time indoors? This is why indoor air quality is so important!

Just by opening a window for a few minutes, you can make a room’s air much fresher. It’s an easy habit to get into every day.
4. Plants Help a Little, Too
Some houseplants can help clean the air by taking in carbon dioxide and releasing oxygen. While they don’t remove all pollutants, they can be a nice addition to a room with good ventilation.
Summary
Good indoor air quality means clean, fresh air that is safe to breathe. It happens when there is enough fresh air coming in, less pollution, the right temperature and humidity, and when machines like air filters and HVAC systems work well. Poor indoor air quality can make you feel sick, tired, and unable to learn or concentrate. Regular indoor air quality testing can help ensure all these elements are balanced.
