Why Monitor PM2.5 During Haze Season in Malaysia?
Why Monitor PM2.5 During Haze Season in Malaysia?
Introduction
Haze is a recurring environmental challenge in Malaysia, affecting offices, schools, hospitals, factories, commercial buildings, and residential properties. During haze episodes, fine airborne particles can enter indoor environments through ventilation systems, doors, windows, and daily building activities.
While outdoor air quality often receives the most attention, indoor PM2.5 monitoring is equally important because people spend most of their time indoors. Monitoring PM2.5 helps organisations understand indoor environmental conditions and make informed decisions about ventilation, filtration, and facility management.
The Temtop M2000 2nd and Temtop LKC-1000S+ 2nd provide real-time PM2.5 monitoring as part of a comprehensive Indoor Air Quality (IAQ) solution.
What Is PM2.5?
PM2.5 refers to fine particulate matter measuring 2.5 micrometres (µm) or smaller.
These microscopic particles can remain suspended in the air for long periods and may enter buildings through outdoor air or be generated by indoor activities such as renovation, cleaning, or dust movement.
Why Is PM2.5 Monitoring Important During Haze?
Monitoring PM2.5 allows organisations to:
Observe indoor particulate levels during haze episodes.
Compare indoor and outdoor environmental conditions.
Evaluate the effectiveness of HVAC systems and air filtration.
Identify areas where airborne particles may be entering the building.
Record environmental trends for facility management.
Support workplace environmental improvement programmes.
Monitoring provides measurable information rather than relying only on visibility or haze conditions outside.
Buildings That Benefit from PM2.5 Monitoring
Routine PM2.5 monitoring is suitable for:
Office buildings
Schools and universities
Hospitals and clinics
Hotels
Shopping malls
Manufacturing facilities
Warehouses
Laboratories
Government buildings
Residential properties
Recommended Monitoring Locations
For better understanding of indoor conditions, measurements can be taken at:
Reception areas
Meeting rooms
Open-plan offices
Classrooms
Staff rooms
Building entrances
Warehouse offices
Production offices
Indoor common areas
Comparing readings from different locations can help identify environmental differences within the same building.
