Eliminate airborne pathogens to reduce harm

Controlling infection risk is a recurring everyday problem for everyone involved in healthcare. Despite considerable efforts being made to comprehensively sterilise all surfaces, both contact and non-contact, and the implementation of air filtration systems, somehow pathogens still manage to get past the best defences. Based on our experience, we believe that approximately 30% of the contaminants that impact outcomes are airborne.

Proven products that hospitals use to manage and reduce infection rates

Airborne pathogens persist in hospitals for many reasons and when people enter any area within the establishment, they are allowing these contaminants access into the same space. Sterile gowns will likely collect hitchhikers along the way and Operating Theatre nurses who prepare the room will allow contaminants to enter the airspace which will remain in the room, despite all the intensive precautions and control protocols.

By adding an Airocide® bioconversion system into the equation the number of Colony Forming Units (CFUs) and all other pathogens plunges. All because Airocide systems eradicate every microorganism they encounter. Airocide’s, patented and NASA developed bioconversion technology eliminates 99.99% of bacteria, viruses, mould, and mildew and removes harmful VOCs, which often result from the constant sanitizing and cleaning of surfaces. Technology which has been proven in clinical studies. Technology which has been proven in real-world hospital Operating Theatres and other, global, medical establishments.

Airocide eliminates airborne pathogens

Filters do not eliminate all organic pollutants and pathogens from the air, as the smallest contaminants pass through even the finest filters. Airocide’s filterless technology can kill 99.99% of organic contaminants and pathogens regardless of size.

Clinical Tests and Case Studies

“In Feb 2022, field tests were performed in a large UK Care Home.  When Airocide was in use the quality of the air improved between 3 and 4 times with more than 75% of the micro-organisms present being safely removed.”

“Following the 5 minute use of an Airocide GCS25 air purification system, the air purification equipment eliminated 99.58% of the present human Coronavirus (HCoV -229E) in a room of 0,54m3.”

“When Airocide equipment is on, the microbiological quality of the air improves, achieving an average decrease of 66% in the number of microorganisms present in the environment”

“When Airocide equipment is on, the diversity of microorganisms present in the classroom air is reduced by 80%”    

“Data confirmed that Titanium dioxide nanoparticles (TNP’s) can enhance the inactivation efficacies and brief exposure to UV–light can effectively degrade HCoV-NL63 virus rendering them non-infectious.”

“Data demonstrates that the photocatalytic properties of Titanium dioxide nanoparticles (TNP’s) are highly effective in inactivating human coronavirus@

“Surgical OR #2 – 100% of viable bacteria found in baseline was removed within 24 hours of using Airocide unit”

“Central Processing – 67% of viable bacteria found in baseline was removed within 24 hours of using Airocide unit”

The researchers found the following:

  • High elimination rate of disease causing microorganisms
  • Eliminates volatile organic chemicals and bioaerosols (odours)
  • No ozone emissions
  • Energy efficient with low maintenance and long product life

Researchers tested and analysed the effluent from the unit and determined that Ozone was


Laboratory tests conducted at the University also revealed that the technology

employed in Airocide produces a 99.9937% kill of CFUs. This level of inactivation overwhelmingly

meets the definition of ‘sanitization’ as established by the Environmental Protection Agency (EPA)

The device was able to inactivate mycotoxin roridin A and the fungal species, Aspergillus niger.

Surgery Operating Room #6

Airborne Bacteria Reduction Testing


A baseline air sample showed 565 CFUs before surgery with HEPA filtering in use, and the initiation of the NASA-developed technology. Following the surgery and implementation of the PCR units, the bacterial count was lowered by 50%. When the room was allowed to return to a baseline level, normal for the room, 566 CFUs were found. When an additional unit was introduced into the operating room, the post-operative condition of the OR was an 85.57% reduction in airborne bacterial CFUs.

Airborne Bacteria Reduction Testing

Researchers performed tests in multiple locations inside the offices of a 26,800 ft3 dental practice. Test results show an average 45.3% reduction in airborne bacteria in 24 hours and an average 80% reduction in airborne mould/fungi in the same 24-hour period.

Two Studies

Airborne Bacterial Reduction Studies

Baseline samples showed 112 CFUs of airborne bacteria (bacterial colony forming units). After a single hour of operation, CFUs dropped by 47.3%. In a second experiment where measures were taken at the beginning and end of a 24-hour period in the operating room, a 92% drop in bacterial CFUs was found.

Mould/Fungi/ Bacteria Reduction Tests

Tests resulted in airborne mould/fungi reduction of 66% in the operating room and 100% in the adjacent corridor in 48 hours. Airborne bacteria were reduced by 82% in the corridor in the same 48 hours.

The technology was proven to efficiently remove ethylene, CFU and VOC concentrations in cold storage indoor air.

Mould / Bacteria Reduction Tests

A clinical study was conducted to determine the initial and sustained reduction of airborne mould and bacteria in two residences. The two three-level residences were 67,000 ft3 and 70,000 ft 3 respectively. Airborne mould was reduced in the homes by an average of 60% in 24 hours and even further to an average of 87% in 6-months. Bacteria in the air inside the homes were reduced to an

average of 57% in 24 hours and maintained a level of 49% lower than baseline in 6 months.

Bacteria / Mould Reduction Testing

Airborne bacteria were reduced by an average of 60% over a 3-week test period and mould/fungi by 70% during the same period.

Bacteria Reduction Testing

A clinical test of the system was conducted at a Georgia corrections facility to determine the ability of the technology to reduce the airborne bacteria inside the facility. The system that was installed in the facility reduced the amount of airborne bacteria by 53% in 16 hours.

State-of-the-art hospitals have recorded astounding reductions in airborne pathogens including those resistant to other treatments after installing Airocide bioconversion systems.
