The 2024 Korea Build, Korea’s largest exhibition specializing in construction, architecture, and interior design, hosted by Messe ESANG, will be held at COEX in Gangnam, Seoul, from July 31 to August 3.
The exhibition covers everything related to building materials, architectural equipment, interior design, and construction planning/execution. In particular, this year’s show highlighted the growing social issue of ventilation systems in school cafeterias with a “Special Pavilion for Improving School Facility Environments”, where products for ventilation, HVAC, and sanitation systems for schools drew strong attention from visitors.

Humaster – The Ultimate Solution for Indoor Air Quality Management
Humaster’s “Humicon” is a multifunctional ventilation and purification system equipped with desiccant dehumidification technology, which draws in humid indoor air, absorbs the moisture into filters, and exhausts it outside.
By reducing humidity, it lowers the perceived indoor temperature while also achieving 98.7% airborne virus reduction and 99.9% airborne bacteria reduction, providing powerful purification performance.
While conventional products have a dehumidification efficiency (L/kWh) of about 2–2.5, Humicon achieves 3.5 or higher. Unlike existing models, it requires no water tank management, and its dehumidification filter is self-regenerating, eliminating the need for replacements.
It also removes fine dust and ultrafine dust as well as providing 99.9% antibacterial and antifungal protection, with the ability to suppress ozone generated by electrostatic filters.
Its ventilation performance is also superior to conventional models. The average sensible heat exchange efficiency for cooling in existing products is 45–55% (65–70% for heating), but this model achieves 65–70% for cooling and 70–72% for heating. Particularly notable is its humidity exchange efficiency: while conventional systems average around 20%, this product boasts an impressive 70% efficiency.
As a result, it not only ensures clean ventilation but also maintains optimal indoor humidity and prevents “air conditioning syndrome,” creating a truly comfortable indoor environment.
