What are the best ways to improve our indoor air quality?

Here are the best ways to improve indoor air quality:

1. Ventilation:

• Increase airflow by opening windows or using exhaust fans.
• Ensure HVAC systems provide adequate air exchange

2. Air Filtration:

• Use HEPA filters to capture >99.95% of particles.
• Consider activated carbon filters for VOCs and odours.

3. Source Control:

• Reduce indoor pollutants by using low-VOC products and minimising chemical-based cleaning supplies.
• Prohibit smoking indoors.

4. Humidity Control:

• Maintain humidity between 40-60% to prevent mould growth.
• Use dehumidifiers in damp areas.

5. Regular Cleaning:

• Vacuum with HEPA filters and dust frequently to remove allergens like dust mites.

6. Air Purifiers:

• Portable air purifiers can reduce PM2.5 levels by up to 92%.
• Best used alongside ventilation systems for optimal results.

7. UVC Light Systems:

• Effective for reducing airborne microorganisms, especially in HVAC systems.

8. Indoor Plants:

• Add air-purifying plants like peace lilies or snake plants to naturally improve air quality.

9. HVAC Maintenance:

• Regularly clean or replace filters and ensure proper system functioning.

10. Educating:

• Educate employees about the importance of proper ventilation, its impact on health and productivity, and encourage them to report issues like stuffiness or odours promptly to help maintain good indoor air quality.

 Combining these strategies provides the best results, as no single method can fully replace proper ventilation and pollutant control.
