Indoor Air Quality Testing for New Office Malaysia HCHO & TVOC Guide
Indoor Air Quality Testing for New Office Malaysia HCHO & TVOC Guide
Before moving employees into a new or newly renovated office in Malaysia, companies normally check the electrical system, air-conditioning, furniture, internet connection and workplace layout.
But what about indoor air quality?
New office furniture, partitions, carpets, flooring, paint, adhesives and renovation materials can affect indoor environmental conditions.
For preliminary screening, a portable instrument such as the NOYAFA JMS17 Indoor Air Quality Tester can be used to monitor HCHO, TVOC, temperature and relative humidity across different areas of an office.
Why Check Indoor Air Before Moving Into a New Office?
A new office may contain a large amount of recently installed material.
Possible sources of volatile compounds can include:
New workstations
Office desks
Storage cabinets
Partitions
Carpets
Vinyl or other flooring
Paint and coatings
Adhesives
Sealants
New furniture
An office can look completely finished while indoor environmental conditions are still changing.
Pre-occupancy screening provides additional information before normal office operations begin.
What Should You Measure?
For basic post-renovation screening, four useful parameters are:
HCHO / Formaldehyde
HCHO is the chemical formula for formaldehyde and may be relevant when investigating certain furniture, engineered wood and interior finishing materials.
TVOC
TVOC means Total Volatile Organic Compounds and provides a broader screening indication associated with volatile organic compounds.
Temperature
Temperature provides environmental context when comparing different rooms and measurement periods.
Relative Humidity
Humidity can differ significantly depending on air-conditioning, ventilation and weather.
The NOYAFA JMS17 combines all four measurements in one portable instrument.
Which Office Areas Should You Test?
Avoid taking only one reading at the entrance.
Consider checking:
Reception area
Open-plan workstation
Meeting rooms
Manager offices
Training rooms
Pantry
New furniture areas
Storage rooms
Newly renovated sections
Rooms with limited ventilation
Different areas can have different furniture density, ventilation and environmental conditions.
Start with a Pre-Occupancy Check
One practical approach is to perform an initial screening before employees move in.
Record:
Location | HCHO | TVOC | Temperature | Humidity
For example:
Recepton readings
Workstation Area readings
Meeting Room readings
Manager Office readings
New Furniture Area readings
This establishes a basic reference for later comparisons.
Compare Before and After Ventilation
Ventilation can change indoor conditions.
A simple comparison procedure is:
Initial Measurement
↓
Record HCHO + TVOC + Temperature + Humidity
↓
Improve Ventilation Where Appropriate
↓
Allow Conditions to Change
↓
Repeat Measurement
↓
Compare Results
This approach is more useful than taking one random measurement without documenting the conditions.
Why Meeting Rooms Are Worth Checking
Meeting rooms are often enclosed and may contain:
Large tables
Chairs
Carpeting
Cabinets
Wall panels
Interior finishes
They may also have different ventilation patterns from open-plan workspaces.
For a newly renovated office, including meeting rooms in the screening process provides a more complete picture.
Check New Office Furniture
New workstations and cabinets are another logical area for preliminary screening.
You can compare:
Open Workspace → Near New Workstation → New Cabinet Area → Meeting Room
If a particular area repeatedly produces different readings, further investigation may be appropriate.
Should You Test Before or After Turning On Air-Conditioning?
The answer depends on what you are trying to understand.
For useful comparison, clearly document the operating condition during each measurement.
For example:
Test A Air-Conditioning Off
Test B Normal Office Air-Conditioning Operation
Rather than mixing different conditions randomly, consistent testing makes the results easier to compare.
Repeat Testing After Occupancy
Indoor conditions can change once an office becomes occupied.
Possible changes include:
Air-conditioning operating hours
Door opening frequency
Number of occupants
Cleaning products
Office equipment
Ventilation patterns
A follow-up screening after occupancy can therefore be useful when investigating changes in the indoor environment.
A Simple Office Monitoring Record
Facility teams can maintain a basic record:
Date | Time | Location | HCHO | TVOC | Temperature | Humidity | AC/Ventilation Condition
This allows measurements to be compared over time rather than relying on memory.
It can also help identify which areas may deserve closer attention.
Can the NOYAFA JMS17 Be Used for Workplace Compliance Testing?
The NOYAFA JMS17 is best positioned as a portable screening and routine monitoring instrument.
Formal workplace indoor air quality assessments may be subject to applicable occupational safety requirements, measurement protocols and professional competency requirements.
Where compliance, certification or occupational exposure assessment is required, use the appropriate professional procedures and equipment.
Do not treat a consumer or general-purpose portable meter reading as an automatic compliance certificate.
Who Can Use the JMS17 for Office Screening?
The instrument may be useful for:
Facility managers
Office administrators
Building maintenance teams
Renovation contractors
Interior designers
Property managers
Business owners
Safety personnel
Its portability makes it convenient for checking multiple office locations with one instrument.
New Office Indoor Air Quality Checklist
Before moving into a newly renovated office, consider:
Complete renovation work
Remove unnecessary renovation materials
Improve ventilation where appropriate
Identify areas with significant new furniture
Screen several representative locations
Record HCHO and TVOC
Record temperature and humidity
Compare before and after ventilation
Repeat measurements where appropriate
Seek professional assessment when formal evaluation is required
This creates a more systematic approach than relying solely on whether the “new office smell” has disappeared.
