Q&A
1. For Nano Jet CDA to enter the medical device market, the relevant research papers and the credibility of the verification institutions are crucial foundations. Please provide papers on the technology and effects, as well as the names of the verification institutions that have been submitted for verification (whether they are TAF or have other certifications).
NanoJet technology originated from micro/nano spray research conducted at the University of Strathclyde in the early 2010s. This research innovated nozzle design and droplet dynamics concepts and was practically applied in the EU FP7 CounterFog project (2014–2017). It developed an advanced nano-scale water mist system capable of rapidly removing chemical, biological, and radioactive particulate pollutants from the air. The research team received the European Commission's (EC) Safety Innovation Award in 2022, the only EU project to receive this honor. Peer-reviewed research demonstrated that 2–20 micrometer nano-water mist droplets can effectively capture and neutralize airborne spores, chemical particles, and pathogens, achieving a removal efficiency of 91–98% within 30 seconds. These achievements laid the scientific and technological foundation for the establishment of Innova NanoJet Technologies Ltd., and successfully transformed academic research into commercial products.
CDa Pro is the world's first product to utilize nano-water mist technology for active air disinfection, overcoming the performance limitations of traditional large-droplet sprayers and filter-based air purifiers. CDa Pro generates ultrafine water droplets that collide with and encapsulate viruses, bacteria, allergens, and pollutants in the air, causing them to settle rapidly. The peer-reviewed paper, *Fast Response CBRN High-Scale Decontamination System: CounterFog* (2017), experimentally demonstrated that nano-water mist can remove 91–98% of Bacillus subtilis spores within seconds, scientifically proving the effectiveness of nano-water mist in air purification and pathogen removal.
To further meet the requirements of the medical device market, Innova NanoJet collaborates with several internationally renowned laboratories to conduct product validation:
LMS Technologies is a renowned independent testing laboratory in the United States, ISO/IEC 17025 certified, specializing in air filtration, aerosol science, and microbiological testing. LMS enjoys a high reputation in North America, conducting product safety and filtration performance testing for numerous leading medical and consumer electronics brands. Testing of the NanoJet CDA using MS2 bacteriophage (a human virus mimic) demonstrated a 98.2% removal rate of airborne viruses within 60 minutes.
The NHS (National Health Service) is the UK's public healthcare system, renowned for its high standards of medical services and research capabilities. At the NHS Health Innovation laboratory, NanoJet CDA achieved a 90% removal rate of Micrococcus luteus bacteria using only water in its testing.
NanoJet CDA is built upon over a decade of rigorous scientific research and EU-award-winning innovative technology, and has been validated by two internationally renowned, ISO-certified, and highly credible laboratories: LMS Technologies (USA) and NHS Health Innovation (UK). Experimental results demonstrate its ability to rapidly (within minutes) and safely (using only water) remove viruses and bacteria from the air. The company is currently conducting ongoing clinical trials and scientific research, laying a solid foundation for its entry into the medical device market.
2. Nano Particle spray is claimed to spray water molecules of nano size. How is this proven effective? Is there a warning mechanism for nozzle malfunctions?
To verify the authenticity and scientific validity of this technology, we conducted multiple measurements with third-party laboratories and professional testing equipment:
- Third-party laboratory verification (LMS Technologies, USA): This laboratory is equipped with a high-precision particle sensor capable of measuring water droplet sizes ranging from 14.9 nanometers to 626.4 nanometers. Experimental results showed that over 94% of the water mist particles were smaller than 100 nanometers, confirming that NanoJet technology can stably generate nanometer-scale water mist.
- In-house professional testing (Dekati ELPI): Innova NanoJet conducted internal validation using the Dekati ELPI (Electrical Low-Pressure Impactor) instrument, which can measure sizes from 6 nanometers to 10 micrometers. The test results also showed that over 90% of the water droplets were smaller than 100 nanometers, highly consistent with results obtained from a third-party LMS laboratory.
These test results scientifically demonstrate that CDa Pro can stably and accurately generate nano-level water mist, which is the core reason why it can quickly capture and remove nano-level viruses and pollutants in the air.
Nozzle Fault Detection and Safety Mechanism
- NanoJet technology nozzles are patented and feature high reliability and long-term stability: the absence of any moving parts reduces the risk of wear or malfunction. The design separates water and airflow, ensuring that they mix and generate nano-sized water mist only in specific areas inside the nozzle, guaranteeing a stable and controllable spraying process.
- Each CDa Pro undergoes rigorous quality testing and flow calibration before leaving the factory to ensure that each nozzle meets the designed performance standards.
- The Innova NanoJet underwent long-term lifespan testing, and the results showed that the entire system maintained stable performance throughout its designed service life without significant performance degradation.
Potential performance degradation: Nozzle performance is primarily affected by the use of substandard water quality, such as water containing lime or other particulate impurities. These impurities can cause nozzle or system blockage, leading to reduced water flow or noticeable water droplet buildup on the machine surface. This is easily noticeable to the user as an early warning sign of performance degradation.
3. Regarding functional differentiation from existing air purifiers, the nanoJet CDA appears to be more effective in open-plan spaces. Are there any survey data on the before-and-after effects from existing customers?
NanoJet CDa Pro factory officially commenced operations and began production on July 11, 2024. Since it has only been on the market for a little over a year, long-term user experience and performance data are still relatively limited. However, since the product's launch, we have actively maintained contact with customers worldwide, collecting user feedback and practical application reports to build a more comprehensive database.
Existing usage reports and data
- Strakonice Hospital Case Study (Czech Republic):NanoJet CDa Pro has been adopted and is being used in Strakonice Hospital in the Czech Republic. This case study has been reported by the international media outlet Climate Control News, demonstrating the hospital's positive impact on air quality.
https://www.climatecontrolnews.com.au/ventilation/hospital-adopts-pro-air
- A report from the National Technical University of Athens (NTUA) in Greece states that tests conducted by the R-NANO laboratory show that NanoJet technology significantly reduces chemical pollutants: formaldehyde (HCHO) is completely removed within 120 minutes. Total volatile organic compound (VOC) concentrations decrease by 57%. This experiment confirms the high effectiveness of NanoJet CDa Pro in improving indoor air quality.
Ongoing international projects
- Alaska, USA: We partner with local fish farms to use NanoJet technology to improve the aquaculture environment and reduce the risk of salmon asthma among workers.
- Birmingham New Street Station in the UK: Collaborative testing of the NanoJet system in a large, open station environment to reduce airborne particulate matter (PMs) and allergens, providing commuters with a cleaner breathing space.
- Paris Metro system: NanoJet technology is being tested to safely and effectively suppress the spread of asbestos fibers in the air, addressing the asbestos dust problem in older metro stations.
4. For open-plan spaces, what are the recommended configuration standards? How many square meters (ping)? What is the air exchange rate (CFM)? Are there any empirical supporting data?
- Under normal environmental conditions, CDa Pro can effectively purify 25 m³ (approximately 880 ft³) of air volume every 1–2 minutes of operation. Based on a typical ceiling height of 2.5 meters (8.2 ft), this corresponds to a floor area of approximately 10 m² (approximately 107 ft²). CDa Pro's water mist jet can reach heights exceeding 5 meters, making it suitable for spaces with high ceilings. In laboratory tests, due to the significantly higher concentrations of contaminants compared to everyday environments, longer operating times are typically required for complete contaminant removal.
- LMS Technologies Testing (USA): Testing space: 4000 ft³ (approx. 113 m³) laboratory. CDa Pro spray time: 5 minutes, removes 98% of MS2 virus.
- NHS Health Innovation Testing (UK): Testing space: 53 m³ laboratory. CDa Pro spray time: 10 minutes, removes >90% of airborne bacteria.
- CDa Pro employs active nano-mist purification technology, fundamentally different from traditional filter-based air purifiers. Filter-based purifiers rely on CFM (cubic feet per minute) to draw air into the filter; the higher the airflow, the faster the cleaning speed. CDa Pro, however, does not require air to pass through a filter. Instead, it actively captures and settles pollutants in the space through nano-sized water mist. Therefore, CFM is not a standard for measuring performance. In open or large spaces, CDa Pro's active purification can quickly cover the entire area, achieving comprehensive air purification.
