climate change and air quality

Climate change can not only affect outdoor air quality, it can also affect indoor air quality. Most people spend all day and night in their homes. You want the air that you breathe in your home to be clean. If your indoor air quality is poor, it can cause a variety of different health issues.

Rising CO2 Levels

CO2 levels are rising thanks to climate change. This can cause outdoor allergens to increase, which can get into indoor air spaces. This can cause issues with asthma, allergies, and more.

Weather Issues

Climate change can cause severe weather events like storms and flooding. This can cause issues with mold, mildew, bugs, and more to infiltrate a home. This will cause issues with indoor air quality. Warmer temperatures and issues with weather patterns can also cause an increase in wildfires. Wildfires can put smoke and other particles in the air, which will lead to poor indoor air quality.

Power Outages

Power outages will occur during severe extreme weather, which is becoming more frequent. This can make it harder to regulate indoor air temperatures. This can also have a negative impact on indoor air quality.

How to Improve Your Indoor Air Quality

There are several ways that you can increase your indoor air quality. These include:

  • Doors and windows. You need to keep doors and windows shut. This is especially true during severe weather events.
  • Leaks. Make sure that your home has no holes or cracks in any of the walls. Leaks will allow poor outdoor air to get into the house.
  • Air purification system. Consider purchasing an air purification system. They make these for each room, or you can get a whole house air purification system.
  • HVAC maintenance. One thing you can do to help with climate change and indoor air quality is to keep your HVAC system maintained. This will help to ensure that it is running at peak efficiency. Make sure that you hire a licensed HVAC professional. They can keep your system maintained and clean.
