Indoor Air Quality Testing
Work-environment and indoor air assessment – dust, gases, VOCs, CO2 and thermal comfort.
Environmental Monitoring
About Indoor Air Quality Testing
Indoor and workplace air quality affects both regulatory compliance and the health and productivity of occupants, and the relevant parameters differ from outdoor air. CVR Labs assesses offices, hospitals, cleanrooms, production halls and enclosed workplaces for respirable dust, CO2, CO, VOCs, formaldehyde, ozone and the temperature/humidity comfort parameters, plus the specific gases and vapours present in a given work environment.
For occupational settings we benchmark exposures against work-environment norms; for offices and healthcare we apply indoor-air-quality guidance for CO2 ventilation adequacy and pollutant build-up. The result tells a facilities or EHS manager whether ventilation, filtration and controls are actually keeping indoor air within acceptable limits.

What we analyse under Indoor Air Quality Testing
The parameter groups below are drawn from this service's own accredited scope; the full searchable list follows.
Indoor air is its own problem
CO2 build-up, VOCs and inadequate ventilation degrade indoor air independently of outdoor quality — and only indoor monitoring reveals it.
Workplaces have exposure norms
Work-environment air must keep dust, gases and vapours within occupational limits; monitoring verifies that engineering controls work.
Comfort and health are measurable
Temperature, humidity and CO2 quantify ventilation adequacy in offices, schools and healthcare — turning complaints into data.

FAQ
Indoor Air Quality Testing — frequently asked questions
Is Indoor Air Quality Testing NABL-accredited at CVR Labs?
Yes. Indoor Air Quality Testing is performed under CVR Labs' NABL ISO/IEC 17025:2017 accreditation (Cert. NABLT0626TN18226) at our Chennai laboratory, with traceable, audit-ready reports accepted for compliance and submission.
What does indoor air quality testing measure?
Respirable dust, CO2, CO, VOCs, formaldehyde, ozone and thermal-comfort parameters, plus any workplace-specific gases or vapours relevant to the environment.
Can you assess workplace exposure?
Yes. Work-environment air is benchmarked against occupational limits to verify that ventilation and engineering controls keep exposures acceptable.
Is this useful for offices and hospitals?
Yes. CO2, VOC and comfort monitoring assesses ventilation adequacy and pollutant build-up in offices, schools, cleanrooms and healthcare settings.
What samples do you accept for Indoor Air Quality Testing?
We routinely handle Offices, hospitals, cleanrooms, workplaces, enclosed environments. Share your exact sample type and target standard and our technical team will confirm the required quantity, method and turnaround.
What parameters are included in Indoor Air Quality Testing?
The Indoor Air Quality Testing panel covers 107 accredited parameters such as % Relative Humidity, 1,1,1,2-Tetrachloroethane, 1,1,1-Trichloroethane, 1,1,2,2-Tetrachloroethane and 1,1,2-Trichloroethane. The full searchable list is on this page — tell us your target and we'll map the right sub-panel for your sample.
