Zero2.5’s efforts in combating the ongoing COVID-19 transmission have been recognized by Straits Times, in an article published yesterday. (Read the article here) Our plant-based and natural fibre ionisers were highlighted in the article to be effective in reducing aerosol concentrations in the air for better COVID-19 safety management.

Zero2.5 has been working closely with Temasek Foundation, Agency for Science, Technology and Research (A*STAR) in collaboration with various public agencies like Land Transport Authority (LTA) to explore the use of our ionizers to reduce the risk of transmission in crowded public transportation venues.

Similar collaboration has also been done with Singapore Tourism Board for the safe resumption of meetings, incentives, conferences, and exhibitions (MICE) activities. The collaboration with public agencies has seen swift deployment of Zero2.5 plant-based ionizers in various national COVID-19 initiatives like Connect@Changi and Temasek’s Project Safeguard.

In an interview with Dr. Ady Suwardi from A*STAR’s Institute of Materials and Engineering (IMRE) by Straits Times, Dr. Suwardi notes that researchers found that plant and natural fibre ionizers were most useful in reducing the concentration of aerosol particles in poorly ventilated indoor spaces.

Professor Loh Xian Jun, the executive director of IMRE commented that “Plants are naturally able to generate ions, so when it is fitted with an electrical ioniser device, the plant is stimulated such that it is able to emit up to a million times more ions compared to a normal plant.”

Our plant-based ionizers work by generating negative air ions (NAI). The charged negative air ions then attract particles in the air, including harmful bacteria and viruses found in aerosol before clumping them together and falling onto the ground. This minimizes the risk of inhaling the aerosolized virus and contracting COVID-19 and other possible airborne infectious diseases. Furthermore, ozone production was found to be negligible during the study.

The same principle guides our plant-based ionizer’s air cleaning capabilities by attracting removing harmful PM2.5 particles in the environment.
