In 2021, the air purifier industry generates $11,422.7 million, and it is projected to capture $31,195.6 million in revenue, rising at a rate of 11.8% from 2021 to 2030, led by the worldwide rising air pollution levels, worsening indoor air quality, and growing prevalence of health concerns and airborne diseases. Besides these, the rising standards of living and increasing disposable income of the population contribute to the rising demand for air purifiers.

The rising prevalence of airborne infections, such as measles, tuberculosis, measles, and common cold over the years contributes to the high demand for air purifiers. For example, tuberculosis is the next-significant infectious killer after COVID-19. Around 10 million people succumbed to death due to tuberculosis, and 7.5 million died of measles. Air purifiers decrease the concentration of airborne contaminants in confined spaces, according to the Environmental Protection Agency of the U.S.

The COVID-19 pandemic has resulted in rising concern for access to cleaner air to minimize the risk of transmission of disease, ascribed to this factor, the demand for air purifiers has significantly grown over the years. In addition, India, Russia, and China are projected to experience a high demand for these purifiers in the near future.

The HEPA and ionic technologies-based air purifiers contribute over 50% of revenue to the industry. HEPA filters are incorporated with HEPA air purifiers that are comprised of multi-layered meshes developed by fine fiberglass threads. These filters possess high-velocity air that dries out the virus. Moreover, these filters capture the tiniest air-borne particles in indoor air and help prevention of allergies and other respiratory diseases. It improves the air quality of asthma patients.

Moreover, ionizers form the filter with less technology. It utilizes positive and negative ions for purification of the air and eliminating allergens that are as small as 0.1 microns. Globally, ionizing technology-based air purifiers cost around $30 to $300. These air purifiers are highly preferred due to their low operational and initial costs, along with less noise.

Under the application segment, residential air purifiers capture a 20% share of the industry, and they are projected to experience a significant growth rate in the coming years. The demand for residential air purifiers is rising due to growing awareness of health, led by the rising concerns over polluted air, and the rising popularity of smart homes.

The most preferred air purifiers for residential applications are based on HEPA technology. Levoit LV-H132 air purifier topped the list of top 10 air purifiers for home usage by Forbes. Residential portable air purifiers are increasingly getting popular due to their small, lightweight, and affordable cost. These air purifiers are equipped with numerous features such as multiple filtration layers, smart controls, and sensors that make them highly preferred among consumers.

APAC generates approx. 40% share of the global industry revenue, attributed to the rising population, rapid urbanization, industrialization, and surging disposable income of the population. In addition, countries such as India, Pakistan, and Bangladesh are among those countries with the worst air quality. China contributes a 50% share to the air purifier industry of the APAC region, led by the presence of manufacturing companies in the country.

Therefore, the growing prevalence of airborne diseases contributes to the growing demand for air purifiers in the industry.
