ACA (Aviation Clean Air) Ionization System For Odor- & Pathogen-Free Flying

June 2025

One of the most annoying things that detracts from the comfort and convenience of flying is lingering, unpleasant odor. Regardless of whether the odors are from jet fuel, catered food from a previous flight, pets, chemicals from the lavatory, or cigarettes/cigars, they can really diminish your enjoyment of the flight. Sure, aerosol sprays can cover those odors during your flight, but the spray will eventually mingle with the other odors, and it’ll be waiting for you again on your next flight.

For the last several years, Duncan Aviation has been installing the air-cleaning ionization system from ACA (Aviation Clean Air), and our clients have been pleasantly surprised by how clean and fresh the system keeps the air in the cabin during all phases of flight.

The system is an active air and surface purifier that works with your aircraft’s existing environmental control system to neutralize odors within minutes. As added bonuses, the ACA system kills viral, bacterial, and fungal pathogens circulating in the air and settled on surfaces and reduces static electricity caused by the relatively low humidity in the cabin.

The ACA system uses an ionization technology that’s in use in many other industries, including hospitals and operating rooms, office buildings, schools, airports, hotels, and other shared community spaces worldwide.

Nate Klenke, Manager of Completions & Modification Service Sales at Duncan Aviation’s facility, has installed the commercial equivalent in his home HVAC system, and he created a portable unit he used in his hotel rooms as he traveled after the COVID restrictions were lifted. He has demonstrated the efficacy of the system to family members and clients alike, and they all experience the same surprise at how quickly the system removes unpleasant odors.

Modification of the air ducts is necessary for the installation, and it can be performed at all of Duncan Aviation’s MRO facilities (Battle Creek, Michigan; Lincoln, Nebraska; and Provo, Utah) and at many of the company’s Satellite Shops located throughout the United States.

Due to the access required, an ideal time to install this powerful little system is during a scheduled maintenance or refurbishment event. However, because it takes less than 2 weeks to install, we can also perform this as a stand-alone event.
