Importance of Clean Indoor Air to Children

Air pollution is certainly a major issue in all large urban areas around the world, and here in Singapore, we have our share of it too. In a previous article, we went great lengths to describe what it is and where does it come from. And today, we are going to dive deeper into the importance of clean indoor air for children.

Although poor air quality is harmful to anyone, children are especially vulnerable to unhealthy particles because their bodies are developing and don’t count with all the means for protection than an adult has.

Avoiding all the different types of pollutants present in the air may seem impossible when living in an urban area. However, parents can take steps towards ensuring that the quality of the air at home is safe for children.

Here are some factors that contribute to poor air quality:


Smoking might be the number one cause of unnecessary indoor air pollution. Children living in a house where people smoke are more prone to ear and sinus infections.

And according to the United States Environmental Protection Agency, second-hand smoke is harmful to children’s health, triggering asthma, sudden infant death syndrome (SIDS), bronchitis, pneumonia and ear infections.

Mold and mildew

Mould and mildew are another major cause of pollution at home. Humidity and heat present the perfect conditions for these organisms to thrive.

Mould is also responsible for numerous allergic reactions causing rhinitis, runny nose, and irritation to those with immune problems.

This problem can be reduced with proper ventilation, or more effectively, installing an air purifier which can remove these tiny fungi from the air thanks to a specialised filtration system. Purlife’s air purifiers come with HEPA filters which capture 99.97% of most airborne particles.


Allergens come in different types and cause many kinds of health conditions. One of them is dust mites which live mainly in padding, mattress, carpet, drapes and stuffed animals such as your kid’s favourite bear.

Since we spend roughly a third of our lives in the bedroom, it is advisable to focus on that area of the house when dealing with the mites. Use mattress covers and pillow covers to reduce your child’s exposure to these types of allergens.

To prevent the spread of dust mites and other particles in your home, you should vacuum regularly. Make sure you have a good filter, otherwise, the vacuum will be helping to stir and redistribute the harmful particles all over the house.


Why is indoor air quality important to children?

  • Most children spend majority of their time either in the house, the school or in public buildings. Poor air quality in those places leave children exposed to pollutants for a lot of time.
  • Poor air quality has several side effects such as headaches, reduced concentration, fatigue, dizziness and sinus inflammation. Unhealthy air can also make your children look tired and weak, as well as can affect the immune response, leaving them more vulnerable to diseases.
  • Children with respiratory conditions are more vulnerable. Take for example asthma sufferers. For them, poor air quality can result in making their condition even worse.
  • Indoor air quality is one of the top risks to public health.
