How NanoJet Technology Enables CDa Air Purifiers to be Among the Best to Help Combat Airborne Viruses and Other Disease Threats in the UK and Beyond
In March 2025, the BBC unveiled the UK’s latest disease-threat watch list, identifying 24 pathogens of rising concern. Among them, a worrying number are respiratory illnesses: adenovirus, human metapneumovirus (HMPV), Middle East Respiratory Syndrome coronavirus (MERS-CoV), influenza, acute flaccid myelitis (AFM), and hepatitis linked to airborne transmission. This watch list represents real and growing health risks, often spread invisibly through the air we breathe.
Let’s break down how these diseases spread, how serious the threat is in the UK and globally, and, most importantly, how NanoJet technology offers a science-backed shield against these microscopic invaders.
How Respiratory Viruses Spread Indoors—And Why It’s a Growing Concern
Respiratory diseases such as adenovirus, influenza, human metapneumovirus (HMPV), MERS-CoV, hepatitis-related syndromes, and acute flaccid myelitis (AFM) commonly spread through the air via tiny, aerosolized droplets expelled when infected individuals breathe, talk, cough, or sneeze. These microscopic particles can remain suspended in the air for hours, especially in poorly ventilated indoor spaces, increasing the risk of inhalation by others. For instance, both HMPV and influenza are known for seasonal surges transmitted through aerosols and direct contact. In the UK, flu-related hospitalisations surpassed 5,000 cases in a single week in January this year, highlighting the significant burden of respiratory infections during winter. Similarly, HMPV has surged, making up 4.9% of hospital respiratory cases in January 2025, the highest rate recorded. While MERS-CoV remains rare in the UK, imported cases have occurred, with high fatality rates posing a serious concern. Globally, the threat is even greater — adenovirus-linked hepatitis has affected hundreds of children across multiple countries, while South America alone has reported over 1.3 million COVID-related deaths, underscoring the deadly potential of airborne pathogens. This global and local resurgence of airborne illnesses reaffirms the critical importance of controlling indoor air quality to limit disease transmission.
Many of these respiratory viruses are primarily airborne, spreading more effectively indoors than outdoors due to stagnant air, poor ventilation, and close human interaction. A review in Science confirms that inhalation of virus-laden aerosols, not just large droplets, is a major transmission route for flu, COVID-19, MERS, and others. It's what you can’t see in the air that’s making us sick.
The Solution: How NanoJet Technology Protects
Us From These Invisible Threats
CDa Pro is not just another air purifier or humidifier — it's a nano-droplet-based active air purification system designed to target and remove airborne pathogens in real time.
CDa Pro emits trillions of nano-sized water droplets, 90% of which are smaller than 100 nm, via supersonic airflow. These droplets collide with and encapsulate any kind of aerosolized particles including viruses and bacteria, increasing their mass and precipitate them out of the breathable air. This technique is highly effective against pathogens like influenza (~100 nm), COVID-19 (~130 nm), adenovirus, and even HMPV.
Proven Effectiveness Against Airborne Pathogens
Scientific validation of NanoJet technology has demonstrated superior efficacy in neutralising airborne contaminants. Third-party laboratory tests conducted at LMS Technologies shows that the system removes over 98% of airborne MS2 virus within minutes of application. Unlike traditional air purifiers that rely on passive filtration over extended periods, NanoJet actively reduces exposure risks in real-time.
Clean Air Matters Now More Than Ever
The addition of multiple airborne viruses to the UK’s disease-threat watch list should be a wake-up call. These pathogens don’t just strike during pandemics — they quietly fill our hospitals each winter, disrupt workplaces, and threaten vulnerable populations.
NanoJet technology represents a science-backed, proactive air purification solution — one that doesn’t just trap viruses but actively removes and isolates them at a microscopic level.
