Unparallel Power. Unsurpassable Performance. Unrivalled Versatility



  • Developed a custom solution incorporating Plascide Technology for the Hong Kong International Airport Control Tower
  • Our unique Plascide technology provides clean-air for travelers going through the Hong Kong- Shenzhen cross-border Mass Transit Railway Station              


Filters are physical porous barriers of varying density, designed to trap and prevent airborne contaminants from returning to the air

Filters can only trap bacteria and airborne particles of specific size, resulting in bulky units to accommodate a wider field of capture. 

Trapped bacteria and viruses continue to be active, reproducing in the filter, resulting in a breeding heaven for pathogens.

Improper handling of contaminated filters can lead to pathogenic micro-organism returning back into the airspace.







Plascide true plasma technology

With its worldwide patent for Plascide technology, Air Halo has created a unique active air-sanitizing generator to sustain true plasma, the "4th state of matter". Such plasma generating technology is more commonly associated with the space industry to enable propulsion into deep space.


Effective and Rapid Sanitation Process
I-SACA's filterless process rapidly fights against viruses, bacteria and fungi.
Neutralize VOCs
Reduces the presence of Volatile Organic Compounds (VOCs) that you will encounter everyday such as within tobacco smoke, paints, etc.

How does Plascide works

  • Within the Plascide air sanitation chamber, an intense ionized gas field is generated at room temperature to propel plasma particles into an energetic state.
  • Air is pulled into the Plascide reactor where it collides with the energised plasma to generate a reaction that causes the sterilization of pathogenic microbes within the air such as H3N2 influenza, MRSA and neutralize toxic chemicals like formaldehyde
  • The reaction leaves the pathogens inactive and harmless



Air Halo's air sanitation technology effectively destroys over 99% of all airborne pathogenic microbes entering the reactor. Designed to operate effectively in a range of environments, Air Halo products are capable of supplying a steady flow of sterile, neutralized air versus alternative technologies.

Can Effectively Sanitizes:

  • Viruses: H3N2, H5N2, H1N1 influenza, MS2
  • BacteriaMRSA, E.Coli, Legionella Pn., M. Tuberculosis
  • Fungus: Aspergillus Versicolor, Cladosporium Cladosporioides
  • Volatile Organic Compounds: Formaldehyde, Benzene
  • Any known or unknown biological pathogens
  • Contamination Reduction Time

    The diagram to the right demonstrates the superior air sanitization performance of our plasma technology over alternative technologies such as UV. 

    Plascide has a much higher sanitization efficacy than other technologies.

    Contaminated air must be processed at a sufficient rate to ensure the indoor airspace has adequate sterilized air to counteract the production of contaminated air.

    Plascide technology combines unmatched performance, neutralization performance and versatility that virtually no other technology commercially available can compare.
