The average person spends 90% of their time indoors. Young children, older adults and those with chronic health conditions tend to spend even more time indoors and are more likely to be affected by indoor air quality problems.
Factors that affect indoor air quality include:
To improve the air quality in your home, remove or reduce pollutant sources and regularly bring in fresh clean air from outside. Air filters and portable air cleaners can also help improve air quality together with air pollutant control and ventilation.
Follow these steps for better air quality:
Eliminate Secondhand Smoke
Cook and Heat Your Home Safely
Clean Your Home Safely
Minimize Dust and Allergens
Keep Temperature and Humidity Comfortable
Renovate and Repair Safely
Choose the Right Air Filter and Portable Air Cleaner
Air filters and portable air cleaners (also known as air purifiers or air sanitizers) vary widely in their ability to remove air pollutants, but some can help improve indoor air quality. Air filters can clean the air throughout a home or building, while portable air cleaners clean air in a single room or area.
For guidance on how to choose the right air filter or cleaner for your space, see the U.S. EPA’s site on Air Cleaners and Air Filters in the Home.
Health effects from indoor air quality problems can range from minor to serious, depending on the type of problem. Health effects can include headaches, tiredness, dizziness, nausea, itchy nose, irritated eyes and scratchy throat. The symptoms usually go away once a person leaves a room or building.
