The Effects of Outdoor Air on Indoor Air Quality

Air quality

The quality of the air in your home can have a profound impact on your overall health and well-being. While we tend to associate air pollution with the air outside of our homes, it’s important to recognize that outdoor air can play a big role in affecting indoor air quality as well. 

Outdoor air pollutants and indoor air quality

The quality of the air outside is contributed to by a range of factors, both natural and human-made. Industrial and power-generation by-products, vehicle emissions, and even dust and plant pollen can negatively affect the quality of the air we breathe. Inadequate ventilation and poor filtration systems, spaces between doors, and open windows can allow outdoor air pollutants to enter the home. These pollutants and substances can accumulate in the home over time, posing risk to the health of those inhaling them.

How your HVAC system can help

Harmful pollutants in the air outside can still find a way into our indoor spaces and cause a range of negative consequences to our health and wellness. Your home heating, ventilation, and air conditioning system can play a critical role in preventing outdoor air pollutants from accumulating in the home. These systems draw in air from the outside, filtering and conditioning it before pushing the air out and into the home, trapping pollutants along the way. 

Those living in areas with especially poor outdoor air quality or who are living with allergies or  respiratory health issues can benefit from also incorporating advanced air purifiers in their homes to help eliminate harmful contaminants. Extra precautions such as using HEPA filters can be utilized to more effectively capture outdoor air particulates and promote better indoor air quality.

Maintaining your HVAC system improves your air quality

The poorer the air quality outside, the bigger the burden placed on your HVAC system when filtering it out. As pollutants accumulate in filters, they obstruct the airflow and reduce the performance of your system. 

This is why HVAC maintenance plays a critical role. 

By consulting with HVAC specialists, we can ensure the proper and routine maintenance of our home HVAC systems and receive specialized advice for improving our indoor air quality. For example, to ensure optimal performance and prevent pollutants from accumulating in your home, it is essential that air filters are replaced on schedule and regular maintenance is conducted by an HVAC technician.
