Improving Indoor Air Quality in Facilities: Tips and Best Practices

Improving Indoor Air Quality in Facilities Tips and Best Practices

Indoor air quality (IAQ) is a critical aspect of facilities management, as it directly impacts the health, comfort, and productivity of building occupants. Poor IAQ can lead to respiratory issues, allergies, reduced cognitive function, and discomfort. Facilities managers play a vital role in ensuring good IAQ by implementing effective strategies and best practices. In this article, we will explore tips and best practices for improving indoor air quality in facilities.

Regular HVAC System Maintenance:

Proper maintenance of heating, ventilation, and air conditioning (HVAC) systems is essential for maintaining good IAQ. Facilities managers should schedule regular inspections, filter changes, and cleanings to ensure optimal performance. Dirty filters and ductwork can accumulate dust, allergens, and pollutants, negatively affecting IAQ. Regular maintenance improves airflow, removes contaminants, and prevents the spread of airborne particles.

Adequate Ventilation:

Proper ventilation is crucial for ensuring fresh air circulation and reducing the concentration of indoor pollutants. Your facilities management company should ensure that ventilation systems are functioning effectively and meet recommended airflow rates. Monitoring carbon dioxide (CO2) levels can indicate inadequate ventilation. When necessary, facilities managers should consider installing additional ventilation systems or utilizing natural ventilation methods, such as opening windows, to improve indoor air circulation.

Effective Source Control:

Source control is a fundamental strategy for improving IAQ. Facilities managers should identify and address potential sources of indoor pollutants, such as volatile organic compounds (VOCs), cleaning products, paints, and furnishings. Implementing policies to minimize or eliminate the use of products containing harmful chemicals or ensuring proper storage and ventilation can significantly reduce indoor pollutant levels.

Regular Cleaning and Maintenance:

Maintaining cleanliness throughout the facility is crucial for good IAQ. Facilities managers should develop and implement a comprehensive cleaning and maintenance schedule. This includes regular dusting, vacuuming, and mopping of floors, as well as cleaning of carpets, upholstery, and other surfaces. Proper waste management practices and prompt removal of trash prevent the buildup of allergens and odors.

Indoor Plants and Biophilic Design:

Incorporating indoor plants into the facility’s design can improve IAQ and contribute to a healthier environment. Plants act as natural air purifiers by absorbing carbon dioxide and releasing oxygen. They also help reduce airborne pollutants and increase humidity levels. Facilities managers should select appropriate plant species that thrive indoors and consider implementing biophilic design principles, integrating nature-inspired elements into the workspace.

Proper Moisture Control:

Excessive moisture can lead to mold growth, which can negatively impact IAQ and cause respiratory issues. Facilities managers should monitor and control moisture levels in the facility by addressing leaks, preventing water infiltration, and promptly addressing water damage or spills. Maintaining proper humidity levels (between 30% and 60%) helps prevent mold growth and promotes a comfortable indoor environment.

Filter Selection and Maintenance:

Choosing high-quality air filters and regularly replacing them is essential for maintaining good IAQ. Facilities managers should select filters with appropriate MERV (Minimum Efficiency Reporting Value) ratings based on the facility’s needs. Regularly inspecting and replacing filters ensures they effectively capture dust, pollen, and other airborne particles. Filter replacement should be done as recommended by the manufacturer or based on IAQ assessments.

Employee Education and Awareness:

Facilities managers should educate employees about the importance of IAQ and encourage their active participation in maintaining good air quality. Providing information on IAQ-related practices, such as proper use of ventilation systems, reporting issues, and avoiding activities that can introduce pollutants (e.g., smoking indoors), helps create a culture of awareness and responsibility.

IAQ Monitoring and Assessment:

Implementing IAQ monitoring and assessment measures enables facilities managers to identify potential issues and take proactive steps to improve air quality. This can involve periodic IAQ testing by professionals to measure pollutant levels, assess ventilation efficiency, and identify potential problem areas. Facilities managers can use the data obtained to develop targeted strategies for IAQ improvement.

Collaboration with Professionals:

Facilities managers should collaborate with IAQ professionals, such as environmental consultants or HVAC specialists, to ensure comprehensive IAQ management. These professionals can provide expertise in assessing and improving IAQ, conducting thorough inspections, and recommending appropriate solutions based on specific facility needs.


Improving indoor air quality is a crucial aspect of facilities management, as it directly impacts the health, comfort, and well-being of building occupants. By implementing strategies such as regular HVAC system maintenance, adequate ventilation, effective source control, regular cleaning, and moisture control, facilities managers can significantly enhance IAQ. Additionally, promoting employee education, utilizing IAQ monitoring and assessment, and collaborating with IAQ professionals contribute to creating a healthier and more productive indoor environment. Prioritizing IAQ demonstrates a commitment to occupant health and ensures a comfortable and conducive workspace for all.
