August 19, 2026 — The global Aircraft Cabin Air Purification Modules Market is valued at USD 350 million in 2026 and is forecast to reach USD 891 million by 2036, expanding at a 9.8% CAGR, according to Fact.MR. The market was valued at USD 318.8 million in 2025.

Demand is rising as airlines plan HEPA replacement cycles, assess UV-C systems, and integrate purification modules into aircraft during production. Line-fit installation can reduce later modification work. MRO providers also benefit from approved HEPA replacement kits that can fit existing certification pathways.

Market Growth Has a Strong Aviation Base

The market has a USD 541 million absolute opportunity through 2036, according to Fact.MR. HEPA filtration, narrow-body aircraft, and line-fit systems are expected to lead demand. HEPA filtration is projected to hold 45.0% share in 2026, while narrow-body aircraft are expected to account for 44.0%. Line-fit systems are projected to capture 58.0%. The United States is estimated to represent 33.0% of the market in 2026.

Third-party aviation data cited by Fact.MR also shows sustained activity. The UK Civil Aviation Authority reported 302 million passengers through UK airports in 2025 in February 2026. The Bureau of Transportation Statistics reported 69.5 million scheduled-service passengers in the United States in January 2026. In September 2025, the Federal Aviation Administration stated that most U.S. commercial airplanes use HEPA filters capable of removing 99.97% of particulate material.

Key Numbers

Segment Breakdown

Technology: HEPA filtration leads with 45.0% share in 2026. Fact.MR attributes its position to proven particulate-removal performance, service familiarity, and established maintenance documentation. UV-C germicidal modules are gaining attention, while photocatalytic oxidation and ionisation remain more selective.

Aircraft Type: Narrow-body aircraft lead with 44.0% share in 2026. Frequent rotations and predictable cabin maintenance requirements support replacement planning for these aircraft.

Fit: Line-fit (OEM) systems lead with 58.0% share in 2026. Integration before aircraft delivery allows purification modules to be certified within the original equipment configuration.

Regions: The report covers North America, Latin America, Europe, East Asia, South Asia and Pacific, and the Middle East and Africa. The United States leads the country comparison by 2026 market share, while Canada records the fastest forecast CAGR among the six profiled countries.

Country Growth Outlook

Fact.MR forecasts Canada at 12.1% CAGR, supported by airline traffic recovery and transborder route pressure. The United States follows at 10.8%, supported by installed-fleet scale. The United Kingdom is projected to grow at 10.7%, followed by Japan at 10.2% and Germany and France at 10.1% each.

Country-level aviation data adds context. Statistics Canada reported 7.0 million Level I carrier passengers and 4.5 million screened passengers in April 2026. Japan's MLIT reported 112.50 million domestic scheduled passengers in FY2025, while JNTO recorded 42,683,600 visitor arrivals in 2025, up 15.8%. Germany's BDLI reported EUR 62.0 billion in aerospace revenue in 2025, including EUR 45.0 billion from civil aviation.

Competitive Landscape

Fact.MR identifies Collins Aerospace, Honeywell Aerospace, Safran / Safran Filtration Systems, Donaldson Company, Inc., Pall Corporation, and Aviation Clean Air, LLC in the company set. Collins Aerospace has relevance in approved aftermarket HEPA retrofit kits. Honeywell Aerospace and Safran / Safran Filtration Systems broaden competition across filtration and cabin-system requirements. Donaldson Company and Pall Corporation add filtration capabilities, while Aviation Clean Air expands the aircraft air-treatment competitive set.

Analyst View

Shambhu Nath Jha, Principal Consultant at Fact.MR, states: “Cabin air modules are no longer evaluated only as replacement filters. Airlines are expected to ask for evidence that filtration and maintenance records stay aligned across aircraft families. Suppliers that combine certification support with service access are better placed to move from trial units into fleet decisions.”
