15 Tips to Improve Indoor Air Quality in Your Home

Indoor air quality directly impacts your health, comfort, and wellbeing. Atlanta's unique climate — with its high humidity, heavy pollen seasons, and year-round HVAC use — makes managing indoor air quality especially important. Here are 15 actionable tips to breathe easier at home.

1. Change Your HVAC Filters Regularly

This is the single most impactful thing you can do for indoor air quality. Replace standard 1-inch filters every 30-60 days, or every 90 days for thicker filters. Use filters rated MERV 8-13 for the best balance of filtration and airflow. During Atlanta's peak pollen season (typically February through May), consider changing filters monthly.

2. Schedule Professional Air Duct Cleaning

Your duct system distributes air throughout your entire home. When ducts accumulate dust, mold, pet dander, and other contaminants, every cycle of your HVAC system spreads these pollutants into your living spaces. Professional air duct cleaning every 3-5 years (or more frequently for homes with pets or allergy sufferers) removes these pollutants at the source.

3. Control Indoor Humidity

Atlanta's humid climate means moisture management is critical. Ideal indoor humidity is 30-50%. Above 60%, mold and dust mites thrive. Use these strategies:

• Run bathroom exhaust fans during and 20 minutes after showers
• Use kitchen range hoods when cooking
• Fix leaks promptly — even small drips can create moisture problems
• Use a standalone dehumidifier in particularly humid areas
• Consider a whole-home dehumidifier for comprehensive control

4. Increase Ventilation

Modern homes are tightly sealed for energy efficiency, which can trap pollutants inside. When outdoor air quality is good (check Atlanta's AQI before opening windows), ventilate your home by:

• Opening windows on opposite sides of the home to create cross-ventilation
• Running bathroom and kitchen exhaust fans
• Using your HVAC system's fresh air intake if available

5. Add Indoor Plants

NASA research has shown that certain houseplants can help filter indoor air pollutants. Effective options include:

• Spider plants (great for beginners)
• Peace lilies (filter multiple VOCs)
• Snake plants (remove formaldehyde)
• Boston ferns (natural humidifiers)
• English ivy (reduces airborne mold)

Note: Keep plants out of reach of pets and children, and avoid overwatering which can promote mold growth in soil.

6. Use Natural Cleaning Products

Many conventional cleaning products release volatile organic compounds (VOCs) that contribute to indoor air pollution. Switch to:

• Unscented or naturally scented products
• Vinegar and baking soda solutions for general cleaning
• Products certified by Green Seal or EcoLogo
• Fragrance-free laundry detergents and fabric softeners

7. Test for Radon

Radon is a colorless, odorless radioactive gas that enters homes from the soil and is the second leading cause of lung cancer in the U.S. Georgia has some areas with elevated radon levels. Test your home with an inexpensive DIY kit or hire a professional tester.

8. Keep Floors Clean

Floors accumulate allergens, chemicals, and pollutants tracked in from outside. Improve air quality by:

• Vacuuming at least twice weekly with a HEPA-filter vacuum
• Using doormats at all entrances and encouraging a no-shoes policy
• Mopping hard floors after vacuuming
• Steam cleaning carpets annually

9. Reduce Sources of VOCs

Volatile organic compounds are emitted by many common household products. Reduce exposure by:

• Choosing low-VOC paints, stains, and finishes
• Storing paints and solvents in a garage or shed, not inside the home
• Allowing new furniture and flooring to off-gas in a well-ventilated space before bringing inside
• Avoiding air fresheners and synthetic fragrances
• Using solid or liquid air fresheners instead of aerosols

10. Install Carbon Monoxide Detectors

Carbon monoxide (CO) is a silent killer produced by gas appliances, fireplaces, and attached garages. Install CO detectors on every level of your home and near sleeping areas. Test them monthly and replace batteries annually.

11. Groom Pets Regularly

Pet dander is one of the most common indoor allergens. Reduce its impact by:

• Brushing pets outdoors at least twice weekly
• Bathing pets monthly or as recommended
• Keeping pets off upholstered furniture and out of bedrooms
• Using HEPA air purifiers in rooms where pets spend the most time

12. Maintain Your Gas Appliances

Gas stoves, ovens, water heaters, and furnaces can release nitrogen dioxide and other combustion byproducts if not properly maintained. Schedule annual professional inspections for all gas appliances and always use your kitchen range hood when cooking on a gas stove.

13. Consider an Air Scrubber or Purifier

Standalone HEPA air purifiers can significantly reduce airborne particles in individual rooms. For whole-home protection, consider an air scrubber installed in your HVAC system. These devices use advanced technology to continuously clean the air throughout your entire home.

14. Address Mold Promptly

In Atlanta's humid climate, mold can develop quickly. Address it immediately by:

• Fixing leaks and water intrusion promptly
• Running exhaust fans in bathrooms and kitchens
• Cleaning bathroom tile and grout regularly
• Inspecting basements and crawl spaces for moisture
• Calling professionals for mold remediation if the affected area exceeds 10 square feet

15. Monitor Your Home's Air Quality

Consider investing in an indoor air quality monitor that measures:

• Particulate matter (PM2.5)
• VOCs
• Carbon dioxide (CO2)
• Humidity and temperature

Real-time data helps you identify when air quality is poor and whether your efforts are making a difference.
