Market Overview
According to the research report, the global biofilter market was valued at USD 2.05 billion in 2022 and is expected to reach USD 4.91 billion by 2032, to grow at a CAGR of 9.1% during the forecast period.
A biofilter is a pollution control system that uses living material—such as bacteria, fungi, and plants—to remove contaminants from air or water. These filters are commonly used in municipal sewage plants, industrial manufacturing facilities, aquaculture systems, and commercial HVAC systems. Compared to traditional mechanical or chemical filtration methods, biofiltration technology is low-maintenance, energy-efficient, and environmentally sustainable.
Country-Wise Market Trends
United States
The United States holds a significant share of the global biofilter market due to its robust environmental policies and investments in infrastructure. Municipalities and industries across the U.S. are deploying biofilters for odor control and stormwater management in urban areas. Increasing awareness of indoor air quality has also led to the adoption of biofiltration systems in commercial and residential buildings. Moreover, the Environmental Protection Agency (EPA) promotes the use of low-impact development techniques, where biofilters play a pivotal role in managing urban runoff.

copyright is witnessing a steady increase in the adoption of biological filtration systems, particularly in the context of wastewater treatment. The country’s commitment to protecting aquatic ecosystems is driving the use of aquaculture water treatment biofilters to regulate ammonia and nitrogen levels. Additionally, Canadian cities are integrating biofilters into green infrastructure projects, such as rain gardens and bioswales, which are essential in managing stormwater and improving water quality.
Germany
Germany is at the forefront of Europe’s biofilter adoption, thanks to its leadership in sustainable air purification and renewable energy. German municipalities use biofilters for controlling industrial emissions, while rural regions utilize them in livestock operations to mitigate odor and nutrient runoff. As part of the EU’s climate goals, Germany has also integrated biofilters into urban ecological planning to combat urban heat islands and enhance biodiversity.
United Kingdom
The UK is a major advocate for sustainable environmental technologies, with strong policies promoting nature-based solutions. Biofilters are being used in stormwater management, particularly in Sustainable Drainage Systems (SuDS) in urban developments. The aquaculture industry is also embracing biofiltration to comply with water discharge regulations. With increasing demand for low-carbon infrastructure, the UK is likely to expand its use of modular biofilter systems in new construction projects.
France
France is emphasizing circular economy principles, which has encouraged industries to adopt environmentally friendly technologies like biological filtration. French wastewater treatment plants are increasingly using biofilters to treat effluents before discharge into natural water bodies. Furthermore, the government has rolled out initiatives to improve air quality in schools and public buildings, creating more opportunities for biofilter-based air purification systems.
China
China, one of the fastest-growing markets for biofilters, is witnessing exponential growth due to aggressive pollution control measures and rapid urbanization. The government’s Blue Sky Action Plan is pushing industries to adopt sustainable air purification technologies, including air biofiltration systems. In southern provinces with booming aquaculture, biofilters are vital in maintaining water quality and reducing fish mortality. China is also promoting eco-industrial parks that integrate natural treatment solutions to manage wastewater and emissions.
India
India faces significant challenges related to urban wastewater and air pollution. Consequently, biofilters are being introduced in municipal wastewater treatment projects, especially in Tier 1 and Tier 2 cities. The National Mission for Clean Ganga is encouraging the use of biofiltration for river rejuvenation by treating polluted water at the source. In addition, India’s aquaculture industry is beginning to recognize the importance of aquaculture water treatment systems to meet export standards.
Japan
Japan is leading innovation in compact biofilter designs tailored for densely populated urban environments. These systems are commonly installed in building ventilation systems for odor control and indoor air quality enhancement. Japan also uses biofiltration extensively in its advanced aquaponics and hydroponics systems. As part of its smart city initiatives, Japan is exploring ways to integrate biofilters into green buildings and underground infrastructure.
