U.S. Hospital & Healthcare Spending For Filtration Market Trends and Insights

CDC and ASHRAE Airflow Compliance Reshape Critical-Care Filtration Demand

The 2025 edition of ANSI/ASHRAE/ASHE Standard 170 revised ventilation requirements for healthcare facilities, adding space types aligned with modern care patterns, such as behavioral health and imaging areas. This impacts the United States hospital filtration market as older hospitals must assess if existing air-handling systems meet compliance standards. Unlike new constructions, these projects often adapt legacy ductwork and mechanical systems. Portable industrial-grade HEPA units, recommended by the CDC, enhance contaminant removal in areas where fixed HVAC systems are insufficient. This creates demand driven by both replacement cycles and supplemental filtration, especially in critical spaces like operating rooms and isolation areas.

CMS and Joint Commission Water-Management Enforcement Drives Sustained Liquid Filtration Investment

CMS mandates that Medicare and Medicaid-certified hospitals, critical access hospitals, and long-term care facilities implement water management policies to mitigate risks from pathogens like Legionella. These policies require ongoing risk assessments, control measures, and monitoring, making water safety a continuous operational priority. The Joint Commission reinforces this focus by emphasizing infection control and environmental care in accreditation processes. This drives consistent demand for point-of-use filters, monitoring tools, and replacement media, ensuring liquid filtration remains a resilient segment even during tighter construction budgets.

Hospital Capital Rationing Extends Filtration Replacement Cycles

Uneven capital access continues to challenge segments of the United States hospital filtration market, despite rising compliance pressures. In 2025, HFMA reported 15 hospital projects exceeding USD 1 billion, reflecting significant investments by major systems. However, smaller facilities face funding shortfalls, with a 2024 ASHE survey showing 79% received less than half of their deferred maintenance funding, and 43% secured only 10%. Budget constraints delay filtration upgrades and extend replacement cycles, slowing project conversions. Vendors now focus on lifecycle savings, energy efficiency, and reduced disruptions to address these challenges.

Segment Analysis

In 2025, air filtration held a 53.14% share, maintaining its lead due to its critical role in hospital ventilation systems across inpatient care, surgeries, and high-risk areas. Hospitals are required to meet stringent air handling standards, with the 2025 Standard 170 update broadening space-level requirements. Liquid filtration followed, driven by potable water safety, dialysis water treatment, and point-of-use controls.

Medical device filtration is projected to grow at a 6.10% CAGR through 2031, making it the fastest-growing segment in the United States hospital filtration market. Growth is linked to ST108 upgrades and increased reprocessing of instruments as procedural volumes shift across care sites. Complex devices now require stricter control over water quality and bioburden during reprocessing. Rising outpatient procedure acuity has increased filtration stages in workflows, pushing demand for validated systems aligned with sterile-processing protocols.

HEPA filtration accounted for 44.45% share in 2025, remaining the largest process category due to its established role in hospital ventilation for high-risk and critical treatment areas. ULPA filtration catered to niche applications requiring tighter containment, while activated carbon and gas-phase systems addressed odor, chemical, and air quality control in specialized areas.

Reverse osmosis is expected to grow at a 7.40% CAGR through 2031, becoming the fastest-growing process segment in the United States hospital filtration market. This growth is driven by dialysis expansion, water safety focus, and the need for reliable sterile-processing water pathways. While reverse osmosis gains attention, it complements rather than replaces HEPA, reflecting increased focus on water-side compliance and budget allocation.
