Indoor air quality (IAQ) testing in Singapore: we measure CO2, formaldehyde, VOCs, particulates, mold and bacteria, then report the findings and next steps.

What you can’t see can harm you. Indoor levels of air pollutants can be 2-5 times higher, and occasionally 100 times higher, than outdoor levels. Big Red’s expertise is in identifying and eliminating environment-related reactions or allergies. If you are currently suffering from environment-related symptoms, and seek to find the root cause–you have come to the right place!
Big Red is one of the only labs in Singapore able to analyze viable spores from Air, Bulk, Dust, Swab, and Rodac contact plates locally in house.
Our objective approach, based on the collection and utilization of scientific evidence, has helped us identify the root causes of a myriad of environmental problems – and has provided effective solutions for our satisfied customers. This has earned us a reputation for delivering Solutions for Healthier Environments.
Fungal spores magnified 1,000 times under a microscope.
We measure the gases in your air (carbon dioxide, carbon monoxide, formaldehyde and ozone), total volatile organic compounds (TVOC), respirable suspended particulates from about 0.75 to 10 microns, relative humidity, temperature, and airflow. We also sample for total bacteria and fungal counts, with mold and bacteria speciation from air or swab samples. Together these show what is in your air and why a space feels the way it does.
Consider testing if occupants report a stale or stuffy space, if there is a musty smell or visible mold, after a new fit-out or new furniture when VOCs and formaldehyde are off-gassing, or after water damage. Facility managers also test before and after remediation to confirm the numbers have improved, and on a routine schedule to keep a healthy environment documented.
Both. Alongside the gas, VOC and particulate readings, we collect air and surface samples and analyze them for total bacteria and fungal counts. Big Red is one of the only providers in Singapore able to analyze viable spores from air, bulk, dust, swab and Rodac contact plates locally and in-house, so we can name the specific mold and bacteria species present, not just report a count.
We provide indoor air quality testing island-wide from our Bedok headquarters, covering every HDB estate, condominium, landed home and commercial premises across Singapore. There is no out-of-the-way surcharge.
You get a written report listing the measured levels for each parameter, how they compare against recognized indoor air guidelines, and clear recommendations. If the results point to a source such as poor ventilation, a duct issue or active mold, the report explains the next step so you can decide how to act.
Because Big Red also carries out air duct cleaning, mold inspection and removal, disinfection and odor treatment, the same team can address whatever the test uncovers. We can also run a follow-up clearance test after the work to confirm the levels have returned to normal.
Big Red offers a complete solution for protection against unseen organisms, fighting germs at the molecular level.
