Advanced Hygiene Solution
AirDefender® was born in the aftermath of the 2003 SARS outbreak in Hong Kong, founded by Albert Wong as a company aiming to provide high quality hygienic solutions through its advanced coating technology. The airDefender research team has continued to explore and innovate since the initial beginnings with studying the benefits of photocatalysis to later moving on to developing way to advance the coating technology, so that it can attack pathogens more effectively. Our scientists continues to learn and grow from their experiments and tests, aiming to create solutions for cleaning and sanitizing that is efficient, sustainable and simple to use.
NASA Ranked Green Innovation
In 2013, airDefender® had a breakthrough and developed a TiO2 Photocatalyst in a Q-dot size − a size beyond the nano definition. This smaller size allowed it to attach to pathogens more effectively, which drastically improved performance and enhanced the cleaning systems. AirDefender® began using this technology in commercial applications for sanitizing homes, offices, public transportations and buildings. And through airDefender's range of products, that innovation is now available to everyone who seeks to create a clean, healthy, and sanitized environment.
As a part of providing healthcare innovations, airDefender®'s quantum technology, which uses the Visible Light Responsive (VLR) catalyst, was ranked by NASA research team as one of the top 3 best samples submitted in 2014.


Natural Germ Block for the New Era
In 2017, airDefender® brought the Q-dot Photocatalysis technology to the general populace by developing a longer-lasting product that could be used daily for head-to-toe protection against pathogens and odors.
In 2020, airDefender® was announced the winner of Hong Kong Emerging Brand for its technology and participation in the innovative world.
