How can I improve my home's indoor air quality?

You can take these steps to improve your indoor air quality (IAQ):
  • Regular Air Filter Replacement: Change or clean your HVAC system’s air filters regularly (every 1-3 months).
  • Professional Air Duct Cleaning: Have your air ducts cleaned by professionals every few years to eliminate dust, mold, and other contaminants.
  • Improve Ventilation: Ensure adequate ventilation in your home to bring in fresh air and exhaust stale air. Use exhaust fans in kitchens and bathrooms.
  • Control Humidity Levels: Use a humidifier or dehumidifier to maintain optimal humidity levels and prevent mold growth.
  • Clean Regularly: Dust and vacuum frequently to minimize airborne particles.
  • Avoid Smoking Indoors: Smoking indoors significantly reduces IAQ.
  • Use Natural Cleaning Products: Opt for natural cleaning products that don’t release harmful VOCs (volatile organic compounds).
  • Monitor Indoor Air Quality: Consider using an indoor air quality monitor to track pollutant levels.
If you have persistent IAQ issues, consult with an HVAC professional or an indoor air quality specialist for further assessment and solutions.
