Continuous air treatment in occupied care settings: what makes it safe?

Independent testing confirms AIRsteril’s effectiveness without risk to residents, staff or patients.

Infection control in care and healthcare environments demands both safety and reliability. Traditional disinfection methods often require areas to be vacated or involve chemical products that cannot be used in occupied environments. AIRsteril technology works differently. It provides round-the-clock air purification in rooms that remain occupied, without risk to the people within them.

How AIRsteril works
Each AIRsteril unit combines ultraviolet light and a catalytic process to neutralise microorganisms and break down odorous or harmful compounds already present in the air. Unlike filter-based systems, it does not rely on air being drawn through the unit, and unlike chemical or fogging systems, it releases no sprays or residues.

This process targets the causes of odour and airborne contamination, creating cleaner, fresher conditions around the clock. Because it operates constantly, it prevents the build-up of pollutants between routine cleans.

Independent safety validation
AIRsteril’s technology has been independently assessed to verify both its performance and safety in occupied environments.

Testing by HygCen Germany confirmed that the process significantly reduces airborne microorganisms while operating safely within recognised air quality standards.

The Eco-Institut also verified that AIRsteril technology continuously reduces harmful volatile organic compounds and produces no harmful by-products. A further assessment by the Fraunhofer Institute, one of Europe’s leading applied science organisations, reviewed these findings and confirmed that AIRsteril units can be operated without compromising air quality or user safety.

Together these studies demonstrate that AIRsteril provides measurable hygiene improvements while maintaining the same safety levels as normal indoor air.

Real-world applications
This combination of safety and performance allows AIRsteril to be used in:

• Bedrooms and living areas, providing background protection without disturbance

• Washrooms, tackling high-risk odour and hygiene areas

• Corridors and treatment rooms, maintaining air hygiene between routine cleaning

Because the system is designed for constant background operation, and with no release of harmful chemicals or residues, it supports hygiene management in occupied environments without changing daily routines.

Safety beyond compliance
For care providers, safety is not only a regulatory requirement but an ethical responsibility. Residents, patients and staff deserve reassurance without unnecessary chemical exposure. AIRsteril delivers that balance, using light and catalytic processes rather than sprays or residues.

Continuous purification maintains a healthier atmosphere, helping staff to work comfortably and ensuring that residents and visitors experience a consistently fresh environment.

The reassurance of proven safety
The most effective air hygiene solutions are those that work safely at all times. AIRsteril’s independent testing confirms both. Its operation is proven to improve air quality, reduce contamination and eliminate odours, all without risk to the people who share the space.
