1. What Is Haze?
Haze occurs when airborne particles and other atmospheric conditions reduce visibility.
Haze may be associated with smoke, combustion emissions, and transported atmospheric pollutants.
However, reduced visibility alone does not establish the concentration of a specific pollutant.
Why Is Haze Relevant to Johor?
Outdoor pollution conditions can influence indoor environments throughout Johor, including:
Johor Bahru
Skudai
Iskandar Puteri
Kulai
Senai
Pasir Gudang
Actual conditions vary with weather, pollution sources, atmospheric transport, and location.
Does Haze Always Mean PM2.5 Is High?
Haze may be associated with elevated fine particle concentrations, but the relationship varies.
Use appropriate air quality information and measurement data rather than relying only on visibility.
Where Can I Check Official Outdoor Air Quality?
Malaysia's Department of Environment provides official outdoor air quality information through APIMS:
2. What Is PM2.5?
PM2.5 refers to airborne particulate matter with an aerodynamic diameter of 2.5 micrometres or smaller.
It is commonly expressed in micrograms per cubic metre (µg/m³).
Potential sources include:
Regional haze
Vehicle exhaust
Industrial combustion
Cooking smoke
Tobacco smoke
Other combustion activities
Why Is PM2.5 Important?
Fine particles can penetrate deep into the respiratory system.
Exposure to elevated PM2.5 concentrations is associated with adverse respiratory and cardiovascular health effects.
Can PM2.5 Be Present Indoors?
Yes.
Indoor PM2.5 may come from outdoor air infiltration or indoor particle-generating activities.
Can I See PM2.5?
Individual PM2.5 particles are too small to be reliably assessed by eye.
A room can appear clean while still containing measurable fine particles.

13. What Is CADR?
CADR stands for Clean Air Delivery Rate.
CADR describes the rate at which an air cleaner delivers air cleaned of a specified pollutant under defined test conditions.
It is commonly expressed in cubic metres per hour (m³/h).
Why Is CADR Important?
An undersized air purifier may provide insufficient clean air delivery for a large room.
Room Volume Formula
Room Volume = Length × Width × Ceiling Height
Example
Room length: 5 m
Room width: 4 m
Ceiling height: 3 m
Room Volume = 5 × 4 × 3 = 60 m³
Simplified Clean Air Change Calculation
Nominal Equivalent Clean Air Changes per Hour = Particle CADR ÷ Room Volume
If the particle CADR is 300 m³/h:
300 ÷ 60 = 5 equivalent clean air changes per hour
This is a simplified sizing estimate, not a guarantee of uniform particle removal or regulatory compliance.
14. How to Check Air Purifier Performance Using a PM2.5 Monitor
A suitable PM2.5 monitor may help users observe changes during air purifier operation.

51. Frequently Asked Questions - PM2.5 Haze and Temtop Monitoring Malaysia
Q1. What is PM2.5?
PM2.5 refers to airborne particulate matter with an aerodynamic diameter of 2.5 micrometres or smaller.
Q2. What is PM10?
PM10 refers to airborne particulate matter with an aerodynamic diameter of 10 micrometres or smaller.
Q3. What is the difference between PM2.5 and PM10?
PM2.5 is a finer particle size fraction, while PM10 includes a broader range of particles.
Q4. Is Temtop AQI the same as Malaysia API?
Not necessarily. The instrument's AQI indication should not automatically be treated as equivalent to Malaysia's official API.
Q5. Can Temtop S1 Up measure PM2.5?
Yes. S1 Up is a compact standalone PM2.5 monitoring option.
Q6. Does Temtop S1+ support Bluetooth?
Yes. Bluetooth App connectivity is a distinguishing feature of the S1+.
Q7. Can Temtop P600 measure PM10?
The P600 has documented PM2.5 and PM10 functions. Confirm the exact supplied version before ordering.
Q8. Can Temtop M10i measure CO2?
Do not assume this. Confirm the exact supported parameters of the selected version.
Q9. Is Temtop M10+ the same as M10i?
Do not assume identical functions. Compare verified specifications.
Q10. What is the difference between M2000 2nd and LKC-1000S 2nd?
The exact supported parameters, operating functions, and technical specifications should be compared for the supplied versions.
Q11. Can a PM2.5 monitor detect TVOC?
Only if the selected instrument has a confirmed suitable TVOC measurement function.
Q12. Can a PM2.5 monitor detect formaldehyde?
Only if the selected instrument has a confirmed suitable HCHO measurement function.
Q13. Can Temtop monitors check air purifier performance?
A suitable PM2.5 monitor may help users observe changes in particle concentrations during air purifier operation.
Q14. Does HEPA remove CO2?
No. Conventional HEPA particle filtration does not remove carbon dioxide.
Q15. What is CADR?
CADR stands for Clean Air Delivery Rate and describes clean air delivery for a specified pollutant under defined test conditions.
Q16. Where should I place a PM2.5 monitor?
Choose a representative occupied location away from strong direct airflow and blocked sensor openings.
Q17. Do Temtop monitors need calibration?
Calibration requirements depend on the model, manufacturer guidance, measurement purpose, and customer requirements.
Q18. Can Temtop monitors be used for formal occupational exposure testing?
Not automatically. Formal testing may require specialised instruments and approved methods.
Q19. Can indoor PM2.5 remain high when windows are closed?
Yes. Outdoor infiltration, indoor particle sources, ventilation, and filtration can affect indoor concentrations.
Q20. How can I reduce indoor PM2.5 during haze?
Use appropriate source control, reduce unnecessary outdoor particle entry, maintain suitable filtration, and monitor indoor conditions.
Q21. Which Temtop monitor is suitable for a bedroom?
S1 Up and S1+ may be considered for general bedroom PM2.5 observation, depending on connectivity preferences.
Q22. Which Temtop monitor is suitable for offices?
A suitable PM2.5-capable monitor may be used for general office particle observation. Confirm the required parameters.
Q23. Can a consumer PM2.5 monitor determine whether a school should close?
No. School closure decisions should follow official instructions.
Q24. Can I request a Temtop quotation for Johor?
Yes. Contact MTM Precision with your preferred model, quantity, application, and delivery location.
