Pure Air Zone - A bioreactor that captures, digests and destroys airborne contaminants using bacterias

Pure Air Zone is capable of mimicking and concentrate what nature does to process air contaminants.

The core technology is a plug-and-play patented bioreactor that uses continuously recirculating water and molecular electrical charge attraction to attract air particles, which are then destroyed within the system using a carefully selected population of safe bacteria from natural sources (non-pathogenic and non-genetically modified) that 'digest' the harmful contaminants of any kind leaving harmless residue behind, which could be used as compost. A system has been built around the technology in order to provide measurable and scalable results. It is used in industries, healthcare, corporate buildings and commercial spaces, and an IoT monitoring system has also been developed to measure the environment in real-time and analyse the machine's performance over its lifetime. Treated spaces are referred to as Pure Air Zones. An app interface informs people of the existence and location of all Pure Air Zones, informing them of where they can gain access to clean, breathable air.

Key features

  • Captures the particles that are too small to respond to gravity and ventilation, which represent 98% of air contaminants
  • Captures and destroys pathogenic air contaminants, including viruses and fine dust, with a 90% efficiency that has been tested in a real operational environment (hospitals)
  • Captures and destroys up to 90% of particles down to 0.3 microns and less
  • Captures and destroys Volatile Organic Compounds (VOCs) such as Formaldehyde, Benzene, Hydrogen Sulfide to non-detectable levels
  • Able to improve by a further 30% the decrease of pathogenic bacteria in a surgery room in combination with laminar flow ventilation
  • Able to selectively capture and destroy pathogenic bacteria up to 99% in a municipal waste treatment plant


  • The initial cost compared to doing nothing is on average: €200 one time charge for each working person and €50/year per person for maintenance and bacteria additives
  • Generates health and energy savings
