The air purifier market was valued at an estimated USD 16.7 billion in 2024, and it is expected to advance at a CAGR of 7.1% during 2024–2030, to reach USD 25.1 billion by 2030.
This is due to the growing air pollution levels across the globe, deteriorating indoor air quality, increasing prevalence of airborne diseases and health concerns, along with the improving standard of living and rising disposable income of individuals.
As per the WHO air quality guidelines, the recommended annual levels and interim targets for common air pollutants, such as PM2.5, is 5 μg/m3; for PM10 is 15 μg/m3; for O3 is 60 μg/m3 (peak season); for NO2 is 10 μg/m3; for SO2 is 40 μg/m3; and for CO is 4 mg/m3. However, according to the WHO, almost the entire global population, i.e., 99% of the people, breathe air that exceeds these limits. In fact, indoor air pollution is one of the primary causes of respiratory illness, cancer, and even eye diseases, along with premature deaths, especially in developing countries.
The prevalence of airborne infections, such as influenza, measles, tuberculosis, and common cold, has been rising over the years. For instance, tuberculosis is the thirteenth-leading cause of death and the second-leading infectious killer after COVID-19. In 2020, approximately 10 million people suffered from tuberculosis and 7.5 million from measles, globally. According to the U.S. Environmental Protection Agency, air purifiers help in reducing the concentration of airborne contaminants, including viruses, in confined spaces. Thus, the rising awareness of healthy living among individuals is increasing the use of air purifiers.
The COVID-19 pandemic caused people to look for access to cleaner air, to minimize the risk of the disease. In fact, San Francisco-based companies Brondell and Molekule are among the first the air purifiers of which have been approved by the FDA to combat the coronavirus.
The HEPA category accounts for the largest share in the market, of 35%. HEPA air purifiers incorporate HEPA filters that comprise multi-layered meshes made of fine fiberglass threads. These filters are bombarded with high-velocity air, which dries out any virus. They capture the smallest airborne particles found in indoor air, thus helping fight asthma and preventing allergies and other respiratory diseases. In fact, these filters are capable of capturing the COVID-19 virus, which is approximately 0.125 microns in size. This is why HEPA filters are recommended in spaces that need highly pure air, such as hospitals, semiconductor manufacturing plants, and industrial and medical cleanrooms.
The photocatalytic category will likely witness the highest CAGR, of 7.7%, over the forecast period. This technology uses titanium dioxide as a photocatalyst and UV light to break down volatile organic compounds and organic pollutants into harmless particles. The increasing awareness of air pollution is driving people to purchase air purifiers with advanced technologies that offer higher efficiency.
The following technologies have been analyzed in the report:
In 2024, the residential category accounts for 40% market share, and they are likely to witness the highest CAGR during the forecast period, on the basis of application. The growth of this category is majorly attributed to the increasing awareness among individuals on their health, because of the concerns arising due to the polluted air, and growing popularity of smart homes.
The HEPA technology is the most-widely accepted by residential air purifier users due to its high reliability and performance.
Residential portable air purifiers are becoming popular as they are small and lightweight, along with being cost-effective compared to in-duct systems. They also have various features, such as multiple filtration layers, sensors, and smart controls, which makes them the choice of a large proportion of consumers.
The hospital category is expected to grow the fastest, during the forecast period. Pure air is vital as hospitals because they host patients with compromised immune systems, who could easily get infected by airborne bacteria, fungi, and viruses. Additionally, the COVID-19 pandemic brought hospital-acquired infections into the limelight, further compelling healthcare facilities to maintain high air quality levels. Pure air is imperative in critical areas, such as operating rooms and cleanrooms, which operate under stringent disinfection and sterilization mandates.

Drive strategic growth with comprehensive market analysis
The Asia-Pacific air purifier market generates approximately 45% of the global revenue, and it will witness the highest CAGR, of 7.5%, over the forecast period. This will be on account of the growing population, rapid urbanization and industrialization, along with the increasing disposable income of individuals. Moreover, India, Bangladesh, and Pakistan are among the countries with the worst air quality, which exceeds the WHO limits by at least ten times, as per the IQAir report of air quality. Moreover, even though China’s air pollution levels dropped in 2021, the country still has significantly polluted air, which raises health concerns among people.
Thus, China leads the market in the region, accounting for around 50% of the market share, being the manufacturing base of a large number of companies in the market. In fact, companies have been massively investing in air purifier R&D and launches. For instance, in 2021, SGS opened a new filtration laboratory in Suzhou, China. The 2,500m2 facility is focused on the filtration testing of compressed air HEPA & ULPA, HVAC & industrial air, and residential air purification technologies.
The following regions and countries have been studied in the report:
The market is fragmented because different countries have different minimum limits on indoor air quality. Moreover, with so many different technologies utilized in these products, companies often have the edge in one of those. Additionally, companies use numerous channels to sell their products, including direct institutional sales, factory outlets, electronics stores, e-commerce portals, and their own websites and outlets. In recent years, major players in the market have been launching products with new technology and features, as well as upgrading the existing product portfolios and expanding their geographical operations, to stay competitive.
