With rising concerns about indoor air pollution, increasing health awareness, and growing urbanisation, air purifiers have become essential components of modern living spaces. These devices, once considered a luxury, are now widely present across residential and commercial spaces to ensure cleaner, safer air.

From removing harmful airborne particles to neutralising viruses and eliminating odours, air purifiers are changing the way we breathe indoors.

Air Purifier devices improve indoor air quality by removing contaminants. These purifiers help remove dust, pollen, smoke, pet dander, volatile organic compounds (VOCs), and airborne pathogens in indoor environments. Based on the technology used, air purifiers provide targeted purification solutions suited to various environments.

The implementation of stringent air quality regulations by governments globally is driving increased adoption of air purifiers. According to Polaris Market Research’s latest analysis, the air purifier market was valued at USD 17.11 billion in 2024. It is expected to grow to USD 34.07 billion by 2034, at a CAGR of 7.2% from 2025 to 2034.

Factors propelling the demand for air purifiers demand

Outdoor air quality is deteriorating in several urban and industrial regions globally. As a result, indoor spaces are also vulnerable to pollution. The infiltration of microscopic pollutants, allergens, and even outdoor contaminants across homes and offices creates potential health risks. Air purifiers help mitigate these effects, especially for people with respiratory disorders.

Increased health and hygiene awareness

The global COVID-19 pandemic brought health and hygiene to the forefront, making clean environments a top priority for consumers and institutions. Air purifiers with HEPA filters and UV-C technologies have gained significant traction owing to their ability to capture viruses and bacteria. The use of these advanced purifiers contributes to better infection control in residential and commercial settings.

Integration with smart home systems

Modern air purifiers are being increasingly integrated with smart home systems. Their integration offers app-based controls, real-time air quality monitoring, voice assistant compatibility, and automation. This helps improve user experience and provides data-driven insights to better indoor environmental management.

Expanding urbanisation and indoor lifestyle

Urban residents spend a significant amount of time indoors. These indoor spaces are often air-conditioned, poorly ventilated environments. As a result, air purifiers are being increasingly used to maintain healthy indoor air standards.

Air purifiers based on technology

Air purifiers can be classified into various categories based on their filtration and purification methods. These include:-

HEPA-based purifiers: High-efficiency particulate air (HEPA) filters are highly effective at capturing a wide range of pollutants. These include dust, pollen, pet dander, and even some bacteria and viruses. HEPA-based purifiers are designed to capture at least 99.97 percent of airborne particles as small as 0.3 microns. The high efficiency of these filters makes them a crucial component of homes, hospitals, and laboratories.

Activated carbon purifiers: Activated carbon purifiers make use of activated carbon to remove impurities from fluids or gases. The high surface area and numerous pores of these purifiers make them highly effective in environments with chemical fumes or tobacco smoke.

UV light air purifiers utilise ultraviolet light to inactivate airborne pathogens, including bacteria, viruses, and mould spores. These purifiers work by damaging the DNA or RNA of these microorganisms, which prevents them from spreading and reproducing. A notable feature of these purifiers is that they use light to disinfect, eliminating the need for chemicals.

Ionisers and electrostatic precipitators: These purifiers release negatively charged ions to bond with airborne particles. This causes the particles to settle on surfaces or be captured on plates. These filters are effective for particulate matter, but concerns about ozone emissions make them less favoured in some regions.

Emerging trends in air purifiers

The air purifier market is rapidly evolving with technological innovations and shifting consumer expectations. Emerging trends in the air purifier landscape include:

Portable and personal air purifiers: Compact devices are gaining traction for personal use. Individuals are increasingly carrying these filters during travel, public transportation, and office environments.

Eco-friendly designs: Manufacturers are developing filters made from sustainable materials. Also, they are creating energy-efficient purifiers that align with environmental goals.

Integration with HVAC systems: Central air purification solutions are being embedded into HVAC systems in commercial buildings and luxury residences. The integration of these systems ensures consistent air quality throughout large spaces.

AI algorithms are now being used to track air quality trends, optimise purification cycles, and provide predictive maintenance alerts for long-term performance.

Conclusion

In conclusion, air purifiers are becoming a crucial element of indoor environmental safety with declining air quality and rising health awareness globally. With continuous technological upgrades and broader adoption across multiple sectors, air purifiers are becoming a staple in ensuring well-being across both personal and professional spaces.
