Human beings build houses to protect themselves against elements such as wind, cold, rain, and snow, among others. What many people don’t realize is that indoor air quality could be up to five times more contaminated compared to the air outside. Unfortunately, if this issue is not solved, it can lead to several health issues, including allergic reactions and asthma flair ups, among others. To decide on the right air purification system to invest in to improve indoor air quality, you first have to determine the kind of air pollutants affecting your house. Below are some common air pollutants found in homes.

Particulate Matter

Air pollutants in your house can be a mixture of dust particles and gasses made up of particulates such as PM2.5 and PM10. PM10 particles can be inhaled and deposited on the surface of the bigger airwaves found on the upper part of the lungs, leading to lung inflammation and even tissue damage. PM2.5 particles can travel deeper into your respiratory system and cause more severe health issues.


Asbestos usually occurs naturally in soil and rock. It is used as a construction material due to its strength and insulating property. Unfortunately, it is a serious indoor air pollutant given that asbestos exposure can lead to health issues, such as asbestosis, mesothelioma, and lung disease.


Radon is a radioactive gas that has no smell, colour, or taste. Since the gas naturally occurs in trace amounts, it is not a severe health hazard outdoors. However, this radioactive gas can lead to health issues when it gets trapped in a house after getting in through holes and cracks. Radon is the second leading cause of lung cancer after smoking. Indoor air quality testing can help you determine if the level of Radon in your indoor air has reached dangerous levels. If the level of Radon in your house is too high, it can be corrected through improved ventilation.

Carbon Monoxide

Carbon monoxide is usually released from fuel-burning heaters and stoves. The gas has no colour or smell but is extremely harmful. The reason carbon monoxide is so dangerous has to do with the fact that it blocks the movement of oxygen in a person’s body. Inhaling the gas can lead to several symptoms, including dizziness, confusion, nausea, tiredness, and headache. When inhaled in large quantities, carbon monoxide can lead to death.

Nitrogen Dioxide

Nitrogen dioxide is quite a reactive gas usually emitted by burning fuel in power plants and motor vehicles. The gas is particularly harmful to people with preexisting respiratory issues. For instance, if people with chronic obstructive pulmonary disease or asthma inhale nitrogen dioxide, they can experience symptoms, such as difficulty in breathing, wheezing, and coughing. Long term exposure to nitrogen dioxide can lead to chronic bronchitis and increase the risk of suffering other respiratory infections.

Biological Pollutants

Biological pollutants are living things or microorganisms that reduce the quality of indoor air. They usually develop in areas with excess food or moisture. Some examples of such pollutants include viruses, bacteria, moulds, pollen, pet dander, and mites, among others. These pollutants can spread disease or cause allergic reactions and asthma flare-ups.

The Takeaway

As you can see, indoor air contamination is a common problem in homes, and it can result from a wide variety of causes. The good news is that indoor air quality can be enhanced by improving ventilation and installing an air purification system. If your indoor air has excess humidity, you may have to install a dehumidifier.
