Global Legionella Filter Market Strategic Research Report

Scope of the Report

The global Legionella Filter market size is predicted to grow from US$ 125 million in 2025 to US$ 221 million in 2032; it is expected to grow at a CAGR of 8.5% from 2026 to 2032.

In 2025, the global production of Legionella filters reached 1.75 million units, with an average selling price of US$73.14 per unit.

Legionella filters are filtration products installed at or near the end of a building's water supply system. They use microporous membranes, ultrafiltration membranes, hollow fiber membranes, or antibacterial composite membrane structures to physically intercept Legionella and related opportunistic pathogenic microorganisms in water sources. Legionnaires' disease filters focus on filtration components for faucets, showers, wall-mounted water outlets, dental equipment water systems, ENT and medical cleaning and rinsing equipment, drinking water points, and some high-risk public building terminals. Product forms include disposable point-of-use filters, replaceable cartridge point-of-use filters, near-point inline filters, and dedicated equipment water system filters.

From a demand structure perspective, hospitals and long-term care facilities remain the core high-value application scenarios, especially ICUs, transplant wards, oncology departments, burn units, hematology wards, elderly care, and areas related to immunocompromised patients. Scenarios such as hotels, public buildings, schools, sports facilities, and ships are more driven by risk events or compliance, and typically do not see the long-term, large-scale deployments seen in hospitals. Equipment-level water system filtration in dental and ENT facilities is a sub-scenarios worthy of separate attention, with its demand logic stemming from equipment water system biofilms, aerosol risks, and medical water quality control. Future growth will not primarily stem from full-scale installation in individual buildings, but rather from more refined identification of high-risk locations, more standardized product replacement cycles, more rigid implementation of hospital water management plans, and increased scrutiny of building water systems by regional public health regulators. In terms of production capacity, the industry's single-line annual capacity is approximately 70,000-80,000 units, with an average capacity utilization rate of 86.39% and a gross profit margin of 21.74%.
