Chemical Odour Elimination at Chulalongkorn Medical Lab

The pathology lab at Chulalongkorn University's Faculty of Medicine runs on formalin and xylene — chemicals that produce a smell so sharp it lingers in your nose after you leave the building. Researchers and lab technicians worked through it every day, breathing in fumes that posed documented long-term health risks. The odour even spread to adjacent storage areas, where mould thrived in the contaminated air.

One ceiling-mount RH-490C NCCO unit. Installed on day one. By day two, staff walked in and noticed the formalin and xylene smell was gone — completely. Over the following weeks, mould stopped growing in storage-room waste bottles, a problem that had persisted for years. One unit. One installation. Immediate and lasting results.
