Rising pollution levels and increasing airborne diseases are expected to be the key factors driving the global air purifier market over the forecast period. Increase in disposable income across the globe, improved standard of living and increasing health consciousness are shifting the air purifier market from being a luxury product to an everyday necessity.
Air purifiers improve the indoor climate of a room and protect the health of the people in urban environments suffering from headaches, cardiovascular diseases, and respiratory ailments. Increased allergies among people, rise in asthmatic patients, and an increasing number of tobacco smokers are driving demand for air purifiers. Air purifiers reduce the allergies among sensitive people by removing dust, pet dander, pollen, mold spores and dust mite feces. Air purifiers also remove smoke particles and Volatile Organic Compounds (VOC’s) which pose a risk to health. Moreover, efficient air purifiers have the capacity to capture some bacteria, virus, and DNA damaging particles.
By technique, air purifiers are segmented into photo plasma technology, thermodynamic sterilization (TSS), ultraviolet germicidal irradiation, filter, activated carbon, polarized-media electronic air cleaners, photocatalytic oxidation (PCO), ionizer purifiers, ozone generators and titanium dioxide technology.
Filters can be further divided into HEPA and MERV filters. Presently, the market is dominated by HEPA purifiers and it is anticipated to remain a major contributor over the forecast period as well. Other segments which are expected to experience growth include activated carbon, ion, and ozone based purifiers.
The market can be segmented by end-use industry into industrial, commercial, residential, and medical. Demand is anticipated to be most significant in the business sector, particularly for the HVAC (Heating, ventilation, and air conditioning) industry. Photocatalytic oxidation (PCO) purifiers are being increasingly used in the HVAC industry by limiting the entry of unconditioned air into building space, thereby saving energy. The residential sector is also expected to see steady growth owing to increased pollution and health consciousness. The industry is estimated to witness growth due to the removal of impurities such as CO2 from the air before processing. By product, the market can be segmented into dust collectors, fume and smoke collectors, vehicle exhaust, mist eliminators, fire/emergency exhausts, air cleaners and industrial UV cleaners.
Several air purifiers pose health and environmental hazards owing to the production of small amounts of ozone, which in the presence of humidity produces NOX. It is expected to act as a primary restraint on the industry growth. Ionic air purifiers provide the maximum amount of ozone. Ozone can damage the lungs, causing coughing, chest pain, shortness of breath and throat irritation. Therefore, the California Air Resources Board announced a ban on indoor cleaning devices which produce ozone beyond a limit.
The key challenges faced by the market are the emission of hazardous by-products, increasing noise level concerns by consumers, the frequency of replacing filters and a great deal of electrical consumption. The operational cost of a purifier for a customer increases due to replacement and electricity costs. Several standardization measures are available to assess the working of a purifier for a client. Clean Air Delivery Rate (CADR), efficient area coverage, air changes per hour, clean air delivery rate are measures being frequently taken up by the customers to assess the effectiveness and efficiency of purifiers. Information on the length of time that the purifier is expected to last and the noise levels are being kept available for inquiry by customers.
North America holds the significant market share, owing to greater disposable income, massive industrialization, environmental protection laws and increased awareness to curb pollution. However, the Asia-Pacific region dominated by China, India, and South Korea which have the negligible presence of air purifiers are projected to experience fastest growth prospects over the forecast period. Growing awareness due to stringent government regulations to curb pollution levels and the health risks associated with infection along with increased urbanization and industrialization is expected to drive demand.
Key vendors in the market include Camfil, Coway, Honeywell, IQAir, and Philips, among others. Mergers and acquisitions were a primary strategy adopted by the players, to increase their presence in the market. Daikin Industries Ltd (USA), Clean Teq Holding Ltd (Australia and Mann Hummel GmbH adopted the above strategy to improve their customer reach, improve on production capacity and focus on core operations. Companies aim to remain abreast in the competitive environment by efficiently investing in manufacturing capabilities and acquiring distribution channels in strategic regions.
