How to Clean Air in a Building

Cleaning the air in a building primarily involves filtration and using air cleaning devices, often integrated with the central HVAC system.

One key method to clean air in a building is to ENHANCE AIR FILTRATION AND CLEANING using the central HVAC system and in-room air cleaning devices. This involves upgrading filters and potentially adding portable units.

Enhancing Air Filtration

Effective air filtration is fundamental to removing particles from indoor air.

• Utilize the Central HVAC System: Your building's heating, ventilation, and air conditioning (HVAC) system is a primary tool for circulating and filtering air. Ensure it is running properly.

• Install High-Efficiency Filters: A crucial step is to install properly sized MERV-13 air filters or the highest rated MERV filters that the HVAC system can accommodate. MERV (Minimum Efficiency Reporting Value) is a standard rating system for air filters. A higher MERV rating means the filter can capture smaller particles more effectively.

  • MERV 1-4: Capture large particles (dust mites, pollen, carpet fibers).
  • MERV 5-8: Capture smaller particles (mold spores, pet dander).
  • MERV 9-12: Capture even smaller particles (legionella, lead dust).
  • MERV 13-16: Capture very small particles (bacteria, tobacco smoke, viruses).
  • MERV 17-20 (HEPA): Capture extremely small particles (all bacteria, viruses, carbon dust).
    Using MERV 13 filters, if your system can handle them, significantly improves air cleaning by trapping a wide range of pollutants.

• Ensure Proper Installation: It's vital to close off any gaps around air filters to minimize air moving around them instead of through them. Gaps allow unfiltered air to bypass the filter, reducing its effectiveness.

Using Air Cleaning Devices

In addition to central filtration, supplemental air cleaning devices can enhance air quality.

• In-Room Air Cleaning Devices: Portable air purifiers can be used in specific rooms or areas to provide additional air cleaning, especially in spaces that may have higher occupancy or specific air quality concerns. These devices often use HEPA filters or other technologies like activated carbon to remove particles, gases, and odors.

Summary of Air Cleaning Methods

Implementing these strategies helps create a healthier indoor environment by reducing airborne contaminants.
