How NanoJet® Air Purifier Technology Removes Odours and VOCs from Indoor Air
This article explains how an air purifier for odour and VOC removal using NanoJet® Technology operates in real indoor environments.
Why an Air Purifier for Odour and VOC Removal Is Often Misunderstood
Odours and volatile organic compounds (VOCs) are among the most persistent indoor air-quality challenges. They originate from everyday sources such as cooking, cleaning products, furniture, building materials, transport environments, and human occupancy.
Most air-purification discussions focus on filters and airflow — typically HEPA filters for particulate matter and activated carbon for odours and gases. While these approaches are well established, they also rely on a key assumption:
That polluted air will pass through the purifier.
In real indoor environments, this assumption does not always hold true.
Corners, stagnant zones, enclosed spaces, and areas behind furniture often experience limited air circulation, allowing odours and VOCs to persist even when a purifier is running continuously.
NanoJet® Technology approaches the problem differently.
What is NanoJet® Technology?
Developed by Innova NanoJet Technologies Ltd, NanoJet® Technology uses trillions of ultrafine, nano-sized water droplets dispersed into the air at high velocity.
These droplets are typically in the submicron range (90% of them are smaller than 100 nanometres) — comparable in size to viruses and ultrafine particulate matter (PM1.0). Their small size and high number allow them to interact directly with airborne pollutants throughout the entire room, not just at a single intake point.
Rather than pulling air into a device, NanoJet® actively introduces droplets into the air volume, enabling direct collision with airborne particles.
How NanoJet® removes odours and VOCs
1. Direct collision and encapsulation
Nano-sized water droplets collide with airborne particulate matter (PM), bacteria, viruses, and water-soluble VOCs. Upon collision, the particulate pollutant becomes encapsulated and the soluble VOCs solute within the droplet. In this process, smells come from particles floating in the air like those from cooking fumes, smoke, “burnt” smell, tobacco smoke, etc., and come from soluble gases (VOCs) can be removed.
This process:
prevents the pollutant from remaining airborne
increases its effective mass
accelerates its removal from the breathing zone
Experimental studies demonstrate that submicron water droplets significantly reduce indoor particulate matter concentrations, including PM1.0, combustion particles, bacteria, and viruses.
This mechanism is supported by peer-reviewed research, including:

2. Whole-room interaction — not airflow-dependent
Traditional filter-based purifiers only treat the air that physically passes through them. If air does not circulate efficiently, pollutants remain untreated.
NanoJet® Technology does not rely on airflow patterns alone. The fine spray disperses throughout the space, reaching:
stagnant air pockets
enclosed corners
areas behind furniture
zones beyond the reach of mechanical airflow
This characteristic is particularly relevant for odour persistence, where VOCs can accumulate unevenly within a room.
Because NanoJet® droplets interact directly with airborne pollutants wherever they are present, the technology enables room-wide reduction of odour-causing compounds, especially particles and water-soluble VOCs, rather than concentrating treatment at a single intake point.
3. Removal of ultrafine particulate matter (PM1.0)
Particles in the 0.3–1.0 µm size range are among the most difficult to capture using conventional mechanical filtration.
According to the National Air Filtration Association (NAFA), filtration efficiency often drops for particles in this size range, sometimes referred to as the “most penetrating particle size” for filters.
NanoJet® Technology addresses this challenge by using droplets of comparable size, enabling effective interaction with:
ultrafine particulate matter (PM1.0)
bacteria and viruses
combustion-related particles that often carry odours
This particle-size matching is a key scientific basis for NanoJet® performance.
What about carbon filters and odour control?
Activated carbon filters are widely used to adsorb gases and VOCs, particularly in highly concentrated airflow systems. They are effective, but they also have limitations:
performance depends on air passing through the filter
adsorption capacity decreases as carbon becomes saturated
filters require regular replacement
stagnant zones remain untreated
NanoJet® Technology does not aim to replace carbon filters in all applications. Instead, it offers a complementary mechanism by:
reducing airborne VOC concentration throughout the space
interacting directly with pollutants in stagnant or low-airflow areas
enabling faster whole-room odour reduction in real-world environments
This distinction is important when evaluating odour control beyond laboratory airflow conditions.
Where NanoJet® Technology is most effective
NanoJet® Technology is deployed in environments where odour linked to particles and soluble VOCs exposure is high and airflow can be uneven, including:
healthcare and clinical spaces
transport and infrastructure environments
kitchens and food-preparation areas
allergy and dust-mite-sensitive homes
enclosed rooms with limited ventilation
In these settings, the ability to treat the entire air volume, rather than only circulated air, is a key differentiator.
A complementary approach to indoor air quality
NanoJet® Technology does not rely on consumable filters or chemical additives. By using water alone, it offers:
filter-free operation
reduced maintenance waste
continuous whole-room interaction
rapid reduction of airborne pollutants
Effective indoor air quality management requires understanding how pollutants behave in real spaces — including where air does not circulate efficiently.
NanoJet® Technology represents a science-based alternative approach to particles and soluble VOCs reduction, grounded in established physical principles and supported by academic research.
Frequently Asked Questions
Is NanoJet® Technology an air purifier?
Yes. NanoJet® Technology is used within air purifier systems, including the AirSancta® CDa series, to remove airborne contaminants from indoor air. Unlike traditional air purifiers that rely on continuous airflow through filters, NanoJet® uses a water-based, ultrafine droplet process to physically interact with pollutants in the room.
How does a NanoJet® air purifier remove odours and VOCs?
NanoJet® Technology generates trillions of ultrafine (~100 nm) water droplets that interact directly with airborne odour molecules and volatile organic compounds (VOCs). Through physical interaction and encapsulation, these pollutants are removed from the breathing zone rather than relying on adsorption through carbon filters.
Does NanoJet® Technology use filters or chemical additives?
No. NanoJet® Technology is filter-less and chemical-free. It uses only water to generate ultrafine droplets, avoiding the need for disposable filters, chemical sorbents, or consumable media.
How is this different from carbon filtration air purifiers?
Carbon filtration air purifiers depend on airflow passing through a fixed filter surface and have a finite adsorption capacity. NanoJet® air purifier technology works throughout the room volume, is not airflow-dependent, and does not rely on adsorption saturation, making it particularly effective for complex or fluctuating odour and VOC environments.
Is NanoJet® air purification suitable for occupied indoor spaces?
Yes. NanoJet® Technology is designed for use in occupied indoor environments and operates in short, pulsed treatment cycles rather than continuous operation. It is intended to complement existing ventilation and indoor air quality strategies.
