Air Purifier Market to Reach USD 34.07 billion by 2034, Growing at 7.2% CAGR

Market Overview

The global air purifier market size was valued at USD 17.11 billion in 2024 and is projected to reach USD 34.07 billion by 2034, growing at a compound annual growth rate (CAGR) of 7.2% from 2025 to 2034.

Air Purifier Market Introduction

An air purifier, also referred to as an air filtration system, helps enhance indoor air quality by removing pollutants and contaminants. It is commonly used in offices, homes, and other indoor environments to create a healthier and more comfortable residing or working place. It acts as an air purification system domestically as it assists in eliminating pollen, dust, mold spores, pet dander, and other harmful particles that may trigger allergies or breathing issues due to indoor air pollution.

These devices are designed to filter the air, ensuring that the inhaled air is clean and free from harmful substances. Air purification systems come in varying sizes and types with varied attributes and technologies to meet diverse needs and preferences. Some air purifiers are specifically designed to target dust particles and are commonly known as air purifiers for dust.

The basic operating principle of an air purifier involves drawing in ambient air and passing it through several filters or technologies to eliminate harmful particles and contaminants. These technologies include HEPA filters, ionizers, activated carbon filters, and UVGI cleaners. HEPA filters are among the most widely used technologies in air purifiers. They confine airborne particles such as pet dander, pollen, dust, and mold spores. HEPA filters are designed to capture particles as small as 0.3 microns with a productivity of 99.97%, indicating that they can efficiently withdraw most pollutants and allergens from the air.

Newer technologies like photocatalytic oxidation (PCO) have entered the air purifier market. This technology has paved the way for energy saving due to its minimal reliance on older, prescriptive designs. This technology excels in fully oxidizing and degrading organic contaminants. It employs short-wave ultraviolet light (UVC), commonly used for sterilization, to activate a catalyst that oxidizes bacteria and viruses. PCO systems are usually combined with existing technologies to purify the air.

Photoelectrochemical Oxidation (PECO) is another advancement that improves quantum efficiency by incorporating electrochemical interactions between the catalyst material and reactive species. PECO systems utilize lower-energy UVA radiation as a light source, which makes them energy-efficient while still being effective.

Air Purifier Market Drivers

Rising Technological Advancements: The air purifier market is witnessing significant technological evolution. These air purifiers are equipped with advanced features such as real time observation of air quality, smart home interactions, and remote control via smartphones. Also, a surge in the Internet of Things and smart home technologies is increasing the market proliferation. There is a conscious effort from the Governments to provide an inculcation of stringent indoor air quality standards and the health benefits of uncontaminated air for the citizens. For instance, in August 2022, Congress passed the Inflation Reduction Act, offering the EPA USD 41.5 billion to address climate changes. Over USD 11 billion of this will assist in ensuring cleaner air and a safe climate for Americans.

Rapid Industrialization: The growing pace of industrialization has led to the release of harmful chemicals, gases, and biological constituents, which has led to higher pollution. This has caused a rise in the demand for air purifiers in manufacturing firms and industrial regions. Also, the growing demand for integrated air purifiers in commercial and domestic facilities due to the rising prevalence of airborne illnesses illnesses is driving the air purifier market growth.

Air Purifier Market Trends

Growing Air Pollution Creating Demand for Air Purifiers

The air purifier market has emerged as a critical segment within the ecological technology landscape, addressing growing concerns over air quality and contamination. For instance, an August 2024 report from the EPA highlighted that approximately 66 million tonnes of pollutants were released into the air in the US in 2023, pushing air purifier growth. The pollutants primarily contribute to the depletion of ozone and the formation of particulate matter, leading to acid rain and reduced visibility. Consumers are growingly seeking healthy indoor air globally. As outdoor pollution worsens, more people are opting to spend time indoors, prompting a shift in strategies to combat air contamination in indoor environments.

Rising Emphasis on Energy Efficient Air Purifiers

The demand for energy-efficient air purifiers is growing. With the rise in operating costs, consumers are increasingly opting for energy-efficient air purifiers, as frequent filter replacements can be costly, adding to the overall maintenance and operational expenses. In fuel-efficient purifiers, prefilters, activated carbon, and HEPA are three prominent technologies utilized. These technologies are known for their effectiveness and efficiency. Many modern air purifiers have an Energy Star tag, indicating that they consume up to 40% less energy as compared to other purifiers. Due to the surge in electricity prices, the demand for fuel-efficient purifiers is anticipated to grow.
