Market size
The global filtration market was valued at $53.5 billion in 2025, according to Global Market Insights. A narrower industrial-filtration definition placed the 2026 market at $40.34 billion, illustrating the effect of market scope and inclusion criteria.[24][73]
Forecast & CAGR
The overall filtration market is projected to grow from $55.2 billion in 2026 to $79.9 billion in 2035, representing a 4.2% CAGR. Industrial filtration is forecast to expand from $40.34 billion in 2026 to $63.38 billion in 2034, a 5.81% CAGR.[24][73]
Market share & regions
North America was identified as the largest regional market in 2025, while Asia-Pacific was the fastest-growing region. In the broader filters market, Asia-Pacific accounted for 46.36% of global revenue in 2025.[24][23]
Segmentation
Industrial filtration is commonly segmented into air and gas filtration and liquid filtration, with applications spanning food and beverage, power generation, semiconductors and electronics, chemicals and petrochemicals, healthcare, metals and mining, and paper and paints. The broader filters market also separates internal-combustion-engine, air and fluid filters.[73][23]
Key players & concentration
Global Market Insights lists Parker Hannifin, Pall, Donaldson, Alfa Laval and MANN+HUMMEL among the leading suppliers. Its 2025 estimate puts Parker Hannifin above 8% share and the top five companies at a combined 30%.[24]
Trends, drivers & challenges
Demand is being supported by urbanization, industrial development, water and wastewater treatment, and air-quality initiatives. The market remains exposed to industrial capital-spending cycles, input-cost pressure and the need to improve filtration performance while controlling energy consumption.[24]
Consumer behavior & competition
Residential water-filtration demand ranges from basic pitcher filters to reverse-osmosis systems costing thousands of dollars, while consumers are advised to compare products with utility water-quality reports and certification databases. Competition therefore spans low-cost consumer products and higher-value engineered systems for industrial and municipal buyers.[74][24]
M&A
Consolidation accelerated in 2026: Donaldson agreed to acquire Filtration Group’s Facet Filtration business for approximately $820 million. Parker Hannifin also sought to acquire Filtration Group Corporation, a transaction reviewed by the European Commission under the EU Merger Regulation.[2][75]
Regulation
Filtration companies face product, environmental and merger-control requirements across end markets. In 2026, the European Commission reviewed Parker Hannifin’s proposed acquisition of Filtration Group Corporation under the EU Merger Regulation, confirming the transaction’s relevance to competition oversight in the sector.[75]
Latest news
The most significant recent development identified was continued consolidation: Donaldson announced its $820 million Facet Filtration acquisition in February 2026, while Parker Hannifin’s proposed Filtration Group acquisition was notified to the European Commission on June 12, 2026.[76][75]
