According to WHO studies, people spend 90% of their life indoor and 91% of the world population are living in poor air condition, which leads to an average of 3.2 million premature deaths per year. The stats published by UN Environment Programme is even more tragic with 99% of the world population suffering from inadequate air quality causing an estimated 7 million premature deaths every year due to Chronic obstructive pulmonary disease (21%), Stroke (17%), Tracheal, bronchus, and lung cancer (15%) Ischemic heart disease (15%) Type 2 diabetes (13%), Lower respiratory infections (13%) and Neonatal disorders (7%).

The mainstream solution to the matters now, air purifiers with HEPA filters, has several issues itself. Firstly, it cannot remove pollutants in the form of gases efficiently and secondly, it requires replacement of filters on a regular basis, which, apart from being costly and inconvenient, generated a huge source of hazardous wastes from the disposed filters.

TreeOTek was established from the initiative to build a substitute solution managed to develop a product named AIRemedy consisted of:

  1. an IoT system capable of measuring and displaying air quality indexes in real time and computing relevant purification processes automatically;
  2. high-density ionizers to remove more than 99% of particulate matters (PM), bacteria and viruses from the processed airflow;
  3. filter media made of layers of activated carbon and volcanic rocks which can capture more than 99% of odors and volatile organic compounds (VOC) from the processed airflow; and
  4. living plants to completely absorb the pollutants captured in the filter media; which ensures no filter replacement is needed and thus no derivative wastes are generated.

The product has been tested and certified by VINACONTROL and then commercialized as from June 2021. The scale-up of the business will undoubtedly contribute to realization of Target 3.9.1 under United Nations’ sustainable goals, i.e., reduction of mortality rate attributed to household and ambient air pollution. It’s also worth noting that such target will be achieved in a much more ecological and sustainable way than the still popular air purifiers with HEPA filters.

In 2024, AIRemedy is now evolving into the second generation with the additional feature of smart and accurate fire detection. The feature has been actually developed from the deeper analysis of the air quality indexes measurable by AIRemedy systems which lead to the build-up of relevant algorithms of fire detection based upon combination of such indexes. The algorithm guarantees early detection of smoldering fires, reduction of false alarms and no installation needed. This will further ensure healthy lives and promote well-being for all at all ages, i.e.  Goal 3 under United Nations’ sustainable goals.
