Camfil, a leading manufacturer of premium air filtration systems for clean indoor air, announced in a Memorandum of Understanding (MOU) the collaboration with CTT SYSTEMS AB ("CTT"). CTT is a market leader in humidity control systems in aviation. The purpose of this agreement is to partner in integrating Camfil's air filtration technology into the aerospace and aviation industry, particularly into CTT's humidifier products.

The partnership aims to develop innovative air filter applications to improve air quality in aircraft cabins. This combines Camfil's expertise and state-of-the-art air filtration solutions with CTT's knowledge and presence in the aviation industry. CTT's main goal in integrating air filtration into its humidifier products is to further enhance air quality for pilots, crew, and passengers. This allows CTT to complement existing clean air solutions without creating additional maintenance or overhaul requirements for airlines. The primary objective is to reduce ozone and/or volatile organic compounds (VOCs). CTT offers a wide range of humidifiers in cockpits and crew rest areas, especially in Boeing 787 and Airbus A350 aircraft. The filter media are fully interchangeable within the current product range of humidifiers/filter media.

"We look forward to working with CTT to develop filters that provide additional value for CTT's customers and further improve air quality in aircraft. We will collaborate closely with CTT to develop customized filters certified for use in aircraft — with high filtration performance and low pressure drop," says Mark Simmons, CEO of Camfil.

"The high-quality filter media are developed for our cockpit humidifiers as well as for crew and cabin areas on Boeing 777X and Airbus A350, as well as for crew rest areas on Boeing 787, to improve air quality without additional maintenance effort. Airlines can initially opt for ozone and VOC reduction," comments Torbjörn Johansson, CEO of CTT Systems.

About Humidity in Aircraft

Without an efficient humidification system, there are signs of dryness in the cabin areas — below 5% relative humidity (RH). Humidifiers in flight decks, crew rest areas, or in the business class offer an impressive increase in humidity to approximately 20% RH, providing higher comfort and well-being.

Passengers and crew benefit on long-haul flights from fewer issues caused by dry air (such as fatigue, jet lag, irritated eyes, dry skin, and the spread of viral illnesses), as well as improved well-being and sleep. The CTT humidifier is based on evaporative cooling and uses a method that successfully prevents the transmission of bacteria.
