Indoor Air Quality Market OVERVIEW

The Indoor Air Quality Market Size is valued at USD 0.17 billion in 2025, is projected to reach USD 0.18 billion in 2026 and further escalate to USD 0.27 billion by 2035, driven by a strong CAGR of 6.3%.In 2025, North America is projected to lead the Indoor Air Quality Market with a 45% share, fueled by urbanization, smart building adoption, and stringent environmental regulations.

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing higher-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden spike in CAGR is attributable to the market's growth and demand returning to pre-pandemic levels once the pandemic is over.

Indoor air quality (IAQ) refers to the cleanliness and safety of the air within buildings and enclosed spaces. It is a critical aspect of public health and comfort, as people spend the majority of their time indoors. IAQ is influenced by factors such as ventilation, pollutants, humidity, and temperature. Poor IAQ can lead to health issues, including respiratory problems, allergies, and fatigue.

Common indoor pollutants include volatile organic compounds (VOCs), mold, tobacco smoke, and particulate matter. Adequate ventilation, air filtration, and reducing pollution sources are essential in maintaining optimal indoor air quality, ensuring the well-being and productivity of occupants. These acts as the factors driving the indoor air quality market growth.

KEY FINDINGS

COVID-19 impact

High Focus on Improving Ventilation During Pandemic Increased Market Growth

The COVID-19 pandemic had a significant impact on indoor air quality. To minimize the virus's transmission, there was a heightened focus on improving ventilation and air filtration in indoor spaces. Many buildings upgraded their HVAC systems to increase the exchange of fresh outdoor air and incorporate high-efficiency air filters.

Additionally, there was an increased awareness of the importance of maintaining proper humidity levels to reduce the virus's viability in the air. These changes, driven by the pandemic, not only helped in mitigating the spread of COVID-19 but also raised awareness about the broader significance of indoor air quality for overall health and well-being in indoor environments.

LATEST TRENDS

Integration of Advanced IAQ Technologies to Accelerate Market Growth

Innovations in indoor air quality (IAQ) have transformed how we perceive and enhance the air we breathe indoors. Advanced IAQ technologies now include smart sensors that continuously monitor air quality and adjust ventilation and filtration systems as needed. High-efficiency particulate air (HEPA) filters, ultraviolet germicidal irradiation (UVGI), and photocatalytic oxidation have gained prominence in purifying indoor air.

Energy-efficient HVAC systems, heat recovery ventilation, and demand-controlled ventilation help optimize IAQ while conserving energy. Smart IAQ management systems, often integrated with building automation, provide real-time data and analytics, allowing for proactive measures. These innovations not only improve health but also promote sustainability and energy efficiency in indoor environments

• According to the U.S. Environmental Protection Agency (EPA), 42% of commercial buildings in the U.S. had installed smart air quality monitoring systems by 2022, reflecting a growing emphasis on real-time indoor air monitoring. Smart sensors help detect pollutants such as VOCs and particulate matter (PM2.5), improving air quality management.

• According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), in 2021, over 35% of new commercial HVAC installations included integrated IAQ monitoring systems to optimize ventilation and reduce indoor pollutants like CO₂ and formaldehyde.

DRIVING FACTORS

Stricter Building Codes, and Sustainability Initiatives Taken to Amplify Market Growth

Several driving factors have led to an increased focus on indoor air quality (IAQ). Concerns about health and well-being, particularly in the wake of the COVID-19 pandemic, have prompted a greater emphasis on cleaner indoor air to reduce the risk of infection. Growing awareness of the adverse health effects of indoor air pollutants like VOCs and allergens has heightened demand for better IAQ.

• The World Health Organization (WHO) reports that indoor air pollution contributes to over 3.8 million premature deaths annually worldwide, motivating both residential and commercial adoption of IAQ solutions to reduce exposure to PM2.5, carbon monoxide, and allergens.

• According to the U.S. Occupational Safety and Health Administration (OSHA), 58% of workplaces in 2021 adhered to indoor air quality regulations, such as proper ventilation and pollutant monitoring. This regulatory pressure encourages organizations to invest in IAQ equipment and services.

Additionally, stricter building codes, green building standards, and sustainability initiatives prioritize IAQ improvements. The desire for energy-efficient buildings often involves better ventilation and filtration systems. As urbanization continues, there's an increasing need to combat outdoor pollution and maintain a healthy indoor environment, driving IAQ enhancements. All of these factors are amplifying indoor air quality market share.

Regulatory Requirements and Certifications Such as LEED and WELL to Propel Market Growth

In addition to health concerns, several other driving factors are shaping the focus on indoor air quality (IAQ). Environmental consciousness and the realization of the environmental impact of buildings have led to an increased demand for eco-friendly, energy-efficient ventilation and filtration systems. The rise of remote work and a shift towards more time spent indoors also underscores the importance of IAQ for overall well-being.

 Moreover, regulatory requirements and certifications, such as LEED and WELL Building Standards, set specific IAQ standards, compelling builders and property owners to prioritize cleaner indoor air. As research continues to uncover the relationship between IAQ and productivity, organizations are investing in healthier indoor environments to boost employee performance and satisfaction.

RESTRAINING FACTOR

Resistance to Change and Lack of Awareness of IAQ Technology to Decrease Market Growth

Several restraining factors challenge the improvement of indoor air quality (IAQ). Budget constraints can limit the implementation of advanced IAQ technologies and systems, especially in older buildings. Resistance to change and lack of awareness can hinder the adoption of IAQ improvements. In some cases, building limitations and designs may make it difficult to retrofit adequate ventilation and filtration systems.

• As per the U.S. Department of Energy (DOE), the average installation cost of a commercial IAQ system ranges from $4,000 to $12,000 per building, while maintenance expenses can reach $1,200 annually, limiting adoption in small- and medium-sized enterprises.

• According to the EPA’s 2021 survey, only 28% of U.S. households actively monitor indoor air quality or use IAQ devices, indicating low awareness and restricting residential market penetration.

Maintenance and operational costs can also deter investments in sustainable IAQ solutions. Furthermore, a lack of comprehensive, enforceable IAQ regulations in certain regions can result in lax standards and low motivation for IAQ enhancements. These factors collectively pose challenges to achieving cleaner and healthier indoor air.
