Problem Statement

Urban indoor air quality makes me unhealthy

Deteriorating urban air quality. In particular indoor air quality in urban settings leads to related health issue of the occupants. 

People are concern of the Indoor Air Quality (IAQ) when the pollutant concentrations always greater indoors than outdoors. In effect they are longing to be away from urban areas where the air quality is better.

Solution Statement

Patented Indoor Botanical Air Bio-filter & Cooler (IBABC)

Patented Indoor Botanical Air Bio-filter & Cooler (IBABC) is the solution to reduce indoor air pollutants, improve the air quality and reduces the temperature.

There is two sections of IBABC, Botanical Biofiltration and Evaporative Cooling section. In effect IBABC is a combination with standard Air-Conditioning & Mechanical Ventilation (ACMV) contributes to to reduction to the usage of energy. Several improvement to the usage of IBABC:

  • Improve indoor thermal comfort – reduce temperature and maintain humidity level – improve building air change rate.

  • ​​​​​Improve IAQ – reduce PM, VOC, and CO2 level

Hence IBABC is a 3-IN-1 unit – air filter, cooler and humidifer.
