RISC, NESTECH and ERIG launch an urban air purification tower in Bangkok, Thailand.


Bangkok may be choking on filthy air but hope for a cleaner future is on the way thanks to a prototype urban air purification tower which is being installed at a property project in downtown Bangkok.

Named “Fahsai” or clear sky, the air purifier can remove pollution and PM 2.5 dust using hybrid auto air purification technology and can purify up to 120,000 cubic meters of air/hour.

The hybrid air purifier tower uses technology developed by Research & Innovation for Sustainability Centre (RISC) by Magnolia Quality Development Corporation Limited (MQDC) and NESTECH Thailand with AGS team.

Kraipichit Muangwong, chief executive of NESTECH Thailand and President of Energy Research Integrate Group (ERIG) said his company hopes the new innovation will serve as a prototype of urban air-purifying towers to substantially help resolve air quality problems, especially PM2.5.


The air purifier is now cleaning air at its location between Siam Discovery and Siam Center. RISC plans this year to install more urban air purifiers in areas with low air quality and high PM2.5 dust levels to protect people’s health.
