8 Simple Ways of Improving Indoor Air Quality

Sometimes, we tend to think that air pollution is only found outside due to smoke, dust, and other pollutants. However, the air inside your house, office, and other buildings can be more polluted than the air outside. According to the Environmental Protection Agency (EPA), indoor air quality can even be five times worse than outdoor air quality.

Low air quality in your greenhouse or other green building that you normally use can have negative effects on your health. It can contribute to fatigue, asthma, and lung disease. If you use a home air quality testing kit, you can check the building’s indoor air quality.

What Causes Low Indoor Air Quality?

Normally, the common pollutants of indoor air include:

  • Dangerous gas leaks.
  • Poor building materials.
  • Contaminants brought into the building by pets.
  • Carbon monoxide due to incomplete combustion of natural gas.
  • Lead and asbestos, especially in older homes.
  • Particles brought in the house via new furniture or mattresses. Chemicals emitted by air fresheners and conventional cleaners.

According to Harvard Health Publishing, most indoor air pollutants are odorless. In this case, there is nothing to alert you when pollution is taking place. You will only notice it when your body reacts negatively, such as sneezing, sleepiness, respiratory problems, and digestive issues.

How to Improve Air Quality

Improving indoor air quality can be the first step towards avoiding asthma and other allergy problems. While it’s not always possible to eliminate all pollutants from the house, you can reduce their number and increase aeration.

Here are 8 proven ways of improving the indoor air quality inside your house, office, or any other green building:

1. Increase Aeration

In other words, ventilate the building. Indoor air quality mainly depends on airflow. When fresh air gets in the house, stagnant air is removed, and the interior is refreshed.

This is the simplest method of improving air quality in your house. You can simply open the windows or doors.

If you live in a crowded urban environment, the air outside might be more polluted than it is inside. In such a case, opening windows and doors may not be an option. However, you can buy a trickle ventilator that cleans the air before it gets into the house.

2. Keep Your House Clean

Good indoor hygiene starts with a clean house. By regularly cleaning your house, you significantly reduce the amount of dust present. You also get rid of mold and pet dander. Typically, house cleaning should focus on the following things:

If you have carpets, vacuum them at least once a week.
Regularly clean all of the house items that attract allergens, such as drapes and bedding. Frequently clear clutter, as it holds a significant amount of dust.

3. Buy an Air Purifier

In some cases, we can’t control the source of the pollution. According to the Environmental Protection Agency, an air purifier is good since it captures dust particles and other irritants.

Okay, you may not remove all the pollutants completely, but you will substantially reduce their concentration. You may use it alongside a dehumidifier, especially in damp areas, to prevent the growth of molds.

4. Regularly Change the AC Filter

If you use a forced-air heating system, check the filters regularly. Normally, filters trap dust and airborne irritants, which meaningfully affects indoor air quality.

In other instances, you may need to have the ducts cleaned, as they also hold dust particles. Although this is not always advisable, the EPA recommends it.

5. Install Vents in the Kitchen

Do you know that many indoor pollutants come from your kitchen? Yes, this is the truth. Gas stoves are not always as clean as you imagine they are. They are significant sources of nitrogen dioxide and carbon monoxide.

The same happens with electric burners. In this context, install a kitchen vent that can be turned on when cooking. Also, remember to always open kitchen windows when cooking.

6. Keep Plants Outside

For some people, indoor plants freshen the air, but this is not always the case. They may collect particles and even foster the growth of molds.

Yes, they release oxygen, but may further pollute the air inside your house. They can also be allergy triggers for you. All the same, consider their benefits versus the problems they are likely to cause and make a decision on whether to keep them inside or outside.

7. Frequently Use Beeswax Candles

Like air purifiers, beeswax candles have amazing air-purifying qualities. As they burn, they release negative ions. Most air pollutants, including pollen, dirt, and dust, are positively charged.

In this context, they will be sucked into the candle. These candles are natural, and they smell good, giving your house a wonderful ambiance. Why not try them?

8. Choose Your Furniture Wisely

Did you know that most furniture items contain glues that release toxins into your house? Yes, and this release may continue for months and years from the day the item was bought.

Like other pollutants, these toxins meaningfully contribute to poor indoor air quality. Always do some research before buying furniture to establish the production methods used. If possible, don’t buy furniture made from all types of particle boards.


Our bodies can’t function properly without oxygen. However, it can be damaging to our respiratory organs if we breathe it in its polluted form. Thus, keeping your house pure and breathable should be a priority. I
