Comprehensive indoor air quality assessment conducted in accordance with DOSH Malaysia Code of Practice by DOSH-certified IAQ assessors.
Assessment performed under normal occupied conditions
Clear reporting aligned with DOSH recommended limits
Indoor Air Quality (IAQ) testing is the systematic measurement and evaluation of physical, chemical, and biological air parameters within occupied indoor environments.
Our IAQ testing service supports employers, facility managers, safety officers, and building operators in assessing workplace air conditions, responding to occupant complaints, and supporting occupational health and safety requirements.
All IAQ assessments are conducted by DOSH-certified IAQ assessors, using calibrated instruments and recognised sampling methods, in accordance with the DOSH Malaysia Code of Practice on Indoor Air Quality.
Indoor air quality directly affects comfort, productivity, and workplace satisfaction. Poor IAQ conditions may lead to recurring complaints, odour issues, or concerns raised by employees or management.
IAQ testing provides factual data to support informed decision-making.
IAQ testing helps organisations to:
IAQ assessments are conducted in accordance with the DOSH Malaysia Code of Practice on Indoor Air Quality, covering the following parameters:
Physical Parameters
Chemical Contaminants
Biological Contaminants
All measurements and samples are collected using calibrated equipment and analysed using recognised methods. Biological samples are analysed by accredited laboratories.
Employers and facility teams commonly conduct IAQ testing when:
This service is commonly integrated into planned maintenance, corrective actions, or system hygiene improvement programmes.
IAQ testing is carried out using a structured and transparent approach to ensure reliable and representative results.
We review the building layout, occupancy profile, ventilation systems, and complaint locations to determine appropriate sampling points.
Physical, chemical, and biological parameters are measured in occupied areas under normal operating conditions.
Air samples for bacterial and fungal counts are analysed by accredited laboratories.
Measured results are evaluated and compared against DOSH recommended limits
A comprehensive IAQ report is issued, detailing results, observations, and findings for reference.
IAQ assessments are conducted by DOSH-certified IAQ assessors using calibrated instruments and recognised sampling methods.
IAQ testing is not routinely mandatory but may be required when indoor air quality concerns arise or when requested by authorities or internal safety management.
Yes. IAQ testing is typically conducted during normal occupancy and operating conditions to reflect actual exposure levels.
The duration depends on the number of sampling points and parameters. Most assessments are completed within one working day, excluding laboratory analysis time.
Testing frequency depends on building conditions, occupancy, and previous findings. Periodic assessment is recommended where concerns persist.
