6. Coughing or difficulty breathing


Poor indoor air quality can lead to health issues like coughing and difficulty breathing.


There are a few things you can do to improve the indoor air quality in your home:


  • Use a vacuum cleaner with a HEPA filter to clean up dust and other small particles from carpets and furniture.

7. Humidity issues


Humidity is a measure of the water vapor in the air. The higher the humidity, the more moisture in the air.
