How to Improve Indoor Air Quality


  • Increase Ventilation – Open windows when possible or use air exchangers to bring in fresh outdoor air.

  • Use Air Purifiers – HEPA filters can help remove dust, pollen, and harmful particles.

  • Avoid Harsh Chemicals – Choose natural cleaning products instead of aerosol sprays and synthetic air fresheners.

  • Maintain HVAC Systems – Regularly clean and replace filters to ensure efficient airflow and filtration.

  • Monitor Humidity Levels – Keep humidity between 40–60% to prevent mold growth.

  • Reduce Indoor Pollutants – Limit smoking indoors, minimize burning candles, and be mindful of indoor gas emissions.

  • Routine Duct Cleaning - Experts generally recommend cleaning air ducts every 3 to 5 years
