Combat against airborne infection  using germicidal air sterilizer

Air Sterilization

WHO has confirmed that COVID-19 is airborne and can remain suspended in air for hours! “Airborne precautions” alert is now activated.

Germicidal air purifier efficiently captures aerosol and droplets suspended in air, and kills any  bacteria and virus in split second.

Our sterilizers are suitable for different usages: from personal space, bathrooms, to large offices.

Smartphone Sterilization

You might have read news saying smartphone germs could be 10 times dirtier than toilet seat. Even worst, the germs now might include coronavirus such as COVID-19 and SARS, as well as various type of influenza A and B viruses.

We have a simple product to help you reducing the risk:
