Air Halo Portable

Micro-lightning Technology

You deserve to breathe clean air

Ensure clean and healthy air anywhere: Work, Vehicles, Home, and even in Public




The need for an

Air Sanitiser

Airborne Bacteria and Virus can lead to influenza, tuberculosis, pneumonia & chicken pox.


Volatile Organic Compounds can cause eye, nose and throat irritation, headaches, loss of coordination, nausea and even damage our vital organs: liver, kidney and central nervous system.



Air Halo Benefits

Air Halo’s Plascide technology delivers:

  • Superior efficiency to eliminate viruses, bacteria and fungi

  • Comparing to Ultra-Violet (UV) irradiation, Photo-Catalyst Oxidation (PCO) and ionisers

Plascide uses micro-lightning technology that does not rely on filters, as filters have zero-sanitization and can release pathogens during replacement.

Attaining IAQ excellent classification standard

More effective than other sanitisation

technologies such as UV

Achievable anti-pathogen efficacy

  What is Plasma?

  • Plasma is the fourth state of matter

  • An electrically energised and ionised gaseous state consisting of positive ions and negative electrons

How does Plascide work?

Within the micro-lightning generator:

  • An intense ionised gas field is generated at room temperature

  • Propels the ions into an energetic state

  • The ionised electrons shatter the biological pathogens and VOCs

In other words, Plascide technology creates a micro-lightning plasma thundercloud to eliminate germs, VOCs as well as odour.

Reduces Volatile Organic Compounds

Eradicates viruses and

other similar pathogens

Destroys airborne bacteria

Verified Proven Technology

The performance of Plascide micro-lightning plasma technology is

validated by well-known laboratory/authority - SGS & Centre for Disease Control and Prevention (PRC)

U.S. Food and Drug Administration launched an enforcement policy

for sterilizers, disinfectant devices, and air purifiers during the coronavirus disease 2019 (COVID-19)

Public Health Emergency – March 2020.

All the Air Halo products are in compliance as non-cleared FDA medical devices for use during the COVID-19 Emergency.

How to choose the best air sanitiser?

By the Clean Air Delivery Rate (CADR) of an air sanitiser.

CADR tests and quantifies air purification performance of an air sanitiser, i.e., its effectiveness and efficiency.


It takes into account the sanitisation time, size of a test room and percentage of airborne bacteria being disinfected.

The energy consumption is another factor to evaluate the rank of an air sanitiser.
