Bio Filter Market Report 2026

The bio filter market size has grown rapidly in recent years. It will grow from $4.13 billion in 2025 to $4.6 billion in 2026 at a compound annual growth rate (CAGR) of 11.4%. The growth in the historic period can be attributed to increasing aquaculture activities, growing focus on water purification, rising awareness of sustainable filtration, expansion of aquarium keeping, and increasing regulatory attention on water quality.

The bio filter market size is expected to see rapid growth in the next few years. It will grow to $7.03 billion in 2030 at a compound annual growth rate (CAGR) of 11.2%. The growth in the forecast period can be attributed to growing demand for advanced water treatment, rising adoption of eco-friendly filtration systems, increasing investment in wastewater solutions, expansion of commercial aquaculture operations, and growing focus on biological purification methods. Major trends in the forecast period include technology advancements in biological filtration, innovations in microbial filtration media, developments in automated filtration systems, research and development in eco-friendly filters, and advancements in bio-based purification materials.

The increasing adoption of aquaculture and fish farming is anticipated to drive the growth of the biofilter market in the coming years. Aquaculture and fish farming involve the controlled cultivation of fish, shellfish, and other aquatic organisms for commercial, nutritional, and ecological applications. This growing adoption is driven by the rising global demand for seafood and the increasing emphasis on sustainable food production systems. Biofilters play a critical role in supporting the expansion of aquaculture operations by maintaining optimal water quality, converting harmful ammonia and nitrites into less toxic compounds, and creating a healthy environment for aquatic species. For instance, in June 2024, according to the European Fishmeal and Fish Oil Producers (EFFOP), a Denmark-based European industry association representing European fishmeal and fish oil producers, aquaculture production in 2024 is expected to increase by 3.3%, reaching 100.8 million tonnes compared to 2023. Therefore, the growing adoption of aquaculture and fish farming is fueling the growth of the biofilter market.

Major companies operating in the bio-filter market are concentrating on advanced filtration solutions, such as eco-designed combined treatment, to enhance wastewater purification, strengthen sustainable infrastructure, and meet increasingly stringent environmental regulations. Eco-designed combined treatment refers to an approach that integrates effective treatment processes with solutions deliberately engineered to reduce environmental impact throughout their life cycle, from production and use to end-of-life disposal. For instance, in March 2024, Premier Tech Water and Environment, a Canada-based provider of water and environmental solutions, introduced the Ecoflo linear biofilter in the United States and Canada. This fully eco-designed on-site treatment and dispersal solution utilizes a natural coco-fiber filtering medium, removes reliance on limited septic sand resources, and functions through gravity-based biofilters without the need for energy-intensive pumps, while all plastic components are designed for reuse or recycling. This launch represents a notable technological advancement by combining low-energy operation with circular-economy design principles, connecting conventional on-site treatment methods with next-generation sustainable biofiltration. It delivers a scalable and efficient solution for long-term wastewater management and enhanced environmental protection.

In May 2023, Xylem Inc., a US-based water technology company offering solutions for water and wastewater management, acquired Evoqua Water Technologies Ltd. for approximately $7.5 billion. Through this acquisition, Xylem seeks to reinforce its biofiltration, membrane filtration, and wastewater treatment capabilities, thereby improving its capacity to provide advanced water solutions to municipal, industrial, and commercial customers globally. Evoqua Water Technologies is a US-based water treatment company that specializes in biofiltration products mainly used for odor control and organic compound treatment in air and water applications.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have impacted the biofilter market by increasing the cost of imported filter media, reactor components, and prefabricated biofilter modules, leading to higher system prices and extended project timelines. The effects are more significant for fluidized bed filters, activated carbon biofilters, and integrated skid systems, particularly in regions reliant on cross-border equipment sourcing such as Asia-Pacific and Europe. Water and wastewater treatment and industrial applications face the highest exposure due to large-scale installations. However, tariffs have encouraged local manufacturing of biofilter media and components, supporting regional suppliers and improving supply chain resilience.

A biofilter is a dedicated filtration system that uses beneficial microorganisms to decompose organic waste and pollutants in water. These microorganisms naturally transform harmful substances into safer, less toxic forms. Since the process is biological instead of mechanical or chemical, it offers a more natural approach to water purification. Biofilters are particularly essential in aquatic settings, such as aquariums and ponds, where waste can accumulate rapidly.

The primary types of biofilters include biological aerated biofilter systems, denitrification biofilter systems, activated carbon biofilters, fixed film systems, and fluidized bed filters. A biological aerated biofilter system is a fixed film treatment process in which wastewater passes through a bed of granular or structured media while air is supplied, enabling attached microorganisms to degrade organic matter and eliminate pollutants within a compact, highly oxygen rich environment. The various filter media used in these systems include ceramic rings, bio balls, moving bed filter media, and others. The key applications of biofilters include volatile organic compound treatment, nitrification, denitrification, odor control, and others, and they are utilized by multiple end users such as stormwater management, water and wastewater collection, chemical processing, food and beverage, aquaculture, and the biopharma industry.

The biofilter market consists of sales of biological trickling filters, moving bed biofilm reactor media, submerged fixed-film biofilters, rotating biological contactor units, and integrated biofilter skids and modules.
