Market Overview

The global air filter market was valued at approximately USD 17.08 billion in 2025 according to Fortune Business Insights (2025), with an alternative estimate of USD 18.63 billion from Grand View Research (2025). Both sources project robust growth, with Fortune Business Insights forecasting a market size of USD 34.66 billion by 2034. The smart air purifier subsegment is growing at a CAGR of 14.1% from 2024 to 2030, reflecting increased adoption of connected devices (Grand View Research, 2024).

Technology & Standards Trends

Two major classification standards dominate the air filter industry: EN 1822 (European) and ASHRAE 52.2 (North American). According to MANN+HUMMEL Air Filtration (2024), EN 1822 classifies HEPA and ULPA filters based on efficiency at the Most Penetrating Particle Size (MPPS), with H14 requiring a minimum efficiency of 99.995%. ASHRAE 52.2 (2024) classifies HVAC filters into MERV 1–16 ratings based on particle capture efficiency between 0.3 and 10 micrometers. HEPA technology (H13/H14) held a 41.7% share of the air purifier technology segment in 2025 (Grand View Research, 2025), indicating strong market preference for high-efficiency filtration.

Competitive Landscape

The global industrial filtration market is led by Parker Hannifin, which held a 15.7% market share in 2024 (Global Market Insights, 2024). Daikin Industries reported filtration revenue of USD 1.12 billion in 2024, focusing on high-end MERV 15 and HEPA products (Report Prime Research, 2024).

Representative manufacturers by cluster:

• Global leaders: Parker Hannifin, Daikin Industries, MANN+HUMMEL
• Specialized OEM/ODM suppliers: Henkaes (customized air filters for HVAC, cleanroom, and residential applications)

Outlook

From 2025 to 2034, the air filter market is expected to nearly double, driven by stricter indoor air quality regulations, expansion of semiconductor and biopharmaceutical cleanroom infrastructure, and adoption of smart, connected filtration systems. The smart air purifier segment's 14.1% CAGR (Grand View Research, 2024) indicates significant growth in IoT-enabled products. Risks include raw material price volatility and varying regional standards (EN 1822 vs. ASHRAE 52.2) that may complicate global supply chains.
