Indoor Air Quality Testing Services
Breathe Easier with Professional Indoor Air Quality Testing
Indoor air quality (IAQ) affects health, comfort, and productivity in homes, offices, and commercial spaces. Prolonged exposure to pollutants can cause fatigue, allergies, and respiratory issues. As such, regular IAQ testing is important to detect hidden contaminants early and prevent long-term health or maintenance problems.
At Newway Laboratories, we provide reliable indoor air quality testing services in Singapore. Our team uses advanced instruments and proven methods to check indoor air quality in your residences and workspaces, keeping your environment safe, compliant, and comfortable.
What Is Indoor Air Quality (IAQ) Testing?
IAQ testing measures pollutants such as dust, mould, VOCs, and carbon monoxide in your space. A detailed indoor air quality inspection uncovers hidden contaminants, ventilation gaps, and moisture issues, helping keep air-conditioned homes and offices in Singapore safe and comfortable.
Need to Check Indoor Air Quality in Your Home or Office?
If you notice allergies, persistent odour, or high humidity, it may be time to check your indoor air quality and identify hidden pollutants that affect comfort and health.
Common Signs of Poor Indoor Air Quality in Singapore
Persistent Odours
Musty or chemical smells may indicate mould, VOCs or other indoor pollutants.
Frequent Headaches
Recurring headaches, fatigue or difficulty concentrating may be linked to poor ventilation or elevated pollutant levels.
Increased Allergies Or Respiratory Issues
Frequent sneezing, coughing or eye irritation may be triggered by airborne allergens or particles.
Excessive Dust Accumulation
Dust that returns quickly after cleaning may point to poor filtration, dirty air ducts or high particulate levels.
Humidity and Mould Growth
High indoor humidity creates conditions that allow mould to grow more easily.

Our Indoor Air Quality Inspection Process
1
Standard IAQ Analysis
We will perform a detailed sampling analysis of the premises, which includes all 10 recommended IAQ parameters (and more) in accordance with SS554:2016+A1:2021.
2
IAQ Management Plan
Our certified IAQ experts will study the findings and develop recommendations to address and control existing / potential IAQ issues.
3
IAQ Implementation Plan
We can also support our customers with a complete range of air conditioning, ventilation and purification services for immediate rectification of identified IAQ problems.
IAQ Remediation & Improvement Services
Following the assessment, Newway may recommend targeted measures based on the pollutants detected, their likely sources and the conditions within your property.
Source Identification
Our findings can help trace pollutants to possible sources, such as building materials, furnishings, mould growth or ventilation issues, so the underlying concern can be addressed.
Ventilation Improvements
Where poor airflow or elevated carbon dioxide levels are detected, we may recommend adjustments or upgrades to improve air circulation and support healthier indoor air exchange.
Air Purification Recommendations
Depending on the contaminants identified, suitable air purification, filtration or HVAC solutions may be recommended to help reduce airborne particles, allergens or chemical pollutants.
Mould Treatment Recommendations
When mould or elevated spore levels are found, we can recommend appropriate treatment, cleaning and preventive measures based on the affected area and severity.
Dehumidification Solutions
If excess moisture is contributing to condensation or mould risk, dehumidification measures may be recommended to help maintain more suitable indoor humidity levels.
Ongoing IAQ Monitoring
For properties requiring continued oversight, periodic testing and monitoring may be recommended to track air quality changes and assess whether improvement measures remain effective.

In Singapore, maintaining good indoor air quality is essential due to the high humidity and urban density. Poor air quality can lead to health issues and reduce productivity. Regular indoor air quality monitoring helps in identifying potential hazards and maintaining a safe environment.
How does formaldehyde affect indoor air quality?
Formaldehyde is a volatile organic compound that can be emitted from building materials, furniture, and household products. High levels of formaldehyde can cause irritation of the eyes, nose, and throat, and long-term exposure may lead to more serious health issues. Here at Newway, we offer formaldehyde testing & removal services to ensure that your indoor air remains safe.
How often should indoor air quality be monitored?
Indoor air quality testing services should be conducted regularly, at least once or twice annually, especially in spaces where people spend a lot of time, such as offices, schools, and homes. Regular monitoring ensures that the air remains within acceptable standards and helps in identifying any emerging issues that need to be addressed.
What should I do if my indoor air quality is poor?
If your indoor air quality is found to be poor, it’s necessary to take immediate action. This may involve improving ventilation, using air purifiers, or addressing specific pollutants like formaldehyde.
