How to improve indoor air quality

Just like outdoor air quality, indoor air quality can pose a risk to your health. We spend a large proportion of our time indoors so it’s important to keep the air as clean as possible.


Here is 4 things you can do to improve indoor air quality.


  1. Check gas outlets such as stove and gas heatings


An American study1 from Lawrence Berkeley National Laboratory and Stanford University estimated that gas burners were estimated to add 25-39% to the week averaged nitrous oxide concentrations.

To prevent this toxic fumes in the house, install venting range hoods to remove as much pollutant from your house as possible. Consider replacing smoky stove for a more efficient burner to minimize gaseous exposure.

 Regularly have your gas stove and heating serviced by a professional to detect leaks in these appliances.


  1. Minimise cleaning products usage


Many of us like to use cleaning products because it makes the house feel cleaner. But many of the cleaning products are a source of toxins left on the surfaces of our homes. These products contains artificial fragrances and synthetic chemicals which emits array of harmful toxins which we breathe in.

Phthalates and BPA are common ingredients in personal care products. A Korean study published in Biological Psychiatry have found preliminary evidence that phthalate could be linked to an increase incidence of ADD/ADHD symptoms in children.2

Choose natural cleaning products or try using a microfiber cloth and water. Microfiber cloths have the ability to cut through grease and dirt without leaving a chemical film around the house.


     3. Keep indoor plants around the house


Plants may have the ability to provide a natural way of removing toxic agents such as benzene, formaldehyde and trichloroethylene from the air, helping to neutralize the effects of these harmful chemicals.

Try placing a few around the house. Not only does it clean the air, it also brightens the house making it a welcoming home.


  1. Reduce the amount of plastic used in the house


Plastic products are one of the culprits for releasing formaldehyde and phthalates. Reduce the amount of plastic used in the house including shower curtains.

Do not heat food in the microwave using plastic containers as this will increase the release of toxic chemicals. Instead use glass containers when heating food.
