People usually spend most of the time at homes, offices, and other indoor environments. Every minute we breathe the air could contribute adverse health effects if the quality of air is poor. Check your indoor air quality regularly is the key step to ensure cleanliness of the air.
Our competent examiner can conduct a walkthrough inspection of premises/building to check if there are any IAQ problems, including odour, ventilation system, exhaust air flow system and unsanitary mechanical room, or trash / stored chemicals in mechanical room, etc. Remedial assessment is also carried out to ensure the IAQ meet the standards.

To improve the indoor air quality (IAQ) and promote public awareness of the importance of IAQ, the HKSAR Government has implemented an IAQ Management Programme. A core element of the Programme is to launch a voluntary IAQ Certification Scheme for Offices and Public Places. For details, please refer to web-site of IAQ Information Centre.
