Reduce Indoor Air Pollution With These Three Most Effective Approaches

  1. Source Control: Taking measures to avoid or minimize the creation of contaminants;
  2. Improved Ventilation: Dilute and displace air pollutants through outdoor air ventilation;
  3. Air Cleaning: Eliminate or remove contaminants from the air in a home through proven air cleaning methods.

Source Control

Of the three, the first approach-source control — is the most preferred & practical approach to improve indoor air quality to remove individual sources of pollution or reduce their emissions. The source control means minimizing the use of materials and products which cause indoor pollution. By employing good hygiene practices & housekeeping practices, you can minimize biological contaminants (including the control of humidity and moisture, occasional cleaning and disinfection of wet or moist surfaces) and control particles.


Another practical and commonly employed practice is — outdoor air ventilation to increase the amount of outdoor air coming indoors & lower the concentrations of indoor air pollutants in the home. This includes installing an exhaust system that increases outdoor air flows, especially when using pollutant sources. Most HVAC systems do not bring fresh air mechanically into the home. Opening doors & windows, operating attic fans when the weather and safety permits. You can either use a window air conditioner with the vent control open that can help to increase the outdoor ventilation rate in the home.

Benefits of good ventilation

  • decreases the amount of indoor air pollutants
  • It helps in limiting the growth of indoor moisture, which can contribute to mold buildup.
  • Mitigates stale indoor air and increases the amount of outdoor air that comes inside the home.

Tips for Improving ventilation in your home

  • Leave interior doors open
  • Ventilate rooms overnight
  • Use bathroom and kitchen fans
  • Use fams to improve airflow
  • open doors & windows when outside conditions permit
  • Consider a home ventilation system
  • use a mechanical HVAC system in your home.

Air Cleaning

Air cleaning is the third approach that is not generally regarded as sufficient but can be used to supplement both ventilation & source control. There are many types of air cleaner available in the market with different sizes and prices. Some of them are electronic particle air cleaners, air cleaners, and ionizers used to remove airborne particles.
Note: Air cleaners are generally not used to remove gaseous contaminants.

Benefits of Air Cleaning

  • Clean Air Offers Anti-Aging Benefits
  • Lower Risk of Heart Disease
  • Better Home Workouts
  • Improved Cognitive Health
  • Reduce Smell and Odour

Tips For Using Air Cleaners

  • Keeps doors & windows closed, use an extra fan
  • Leave the Air Cleaner On – 24/7
  • Indoor plants make the best air purifiers.
