Air Quality Alert · April 2026
🌫️ The Haze Is Back. Are You Measuring What Matters?
Current Situation: Smoke haze from ongoing fires in Johor’s Pengerang and Kota Tinggi districts has been drifting into Singapore. Residents across the island have reported a persistent burning smell, with some areas recording PM2.5 readings in the unhealthy range. NEA is actively monitoring the situation as dry, warm conditions continue.
Why “It Smells Fine” Is Not Good Enough
When haze descends on Singapore, the most dangerous particles are often the ones you cannot see or smell. Fine particulate matter — PM2.5 and smaller — penetrates deep into the lungs and bloodstream. For workers in industrial environments, construction sites, or even open-plan offices, the risk compounds quickly.
PSI readings give you a city-wide average. They do not tell you what’s happening on your floor, in your facility, or in the breathing zone of your team. That is precisely why real-time, on-site aerosol monitoring is no longer a luxury — it is a professional obligation.
And when it comes to aerosol monitors, nothing comes close to the TSI DustTrak™ series .
“The DustTrak DRX is the only monitor that simultaneously measures PM1, PM2.5, Respirable, PM10 and PM Total — no size-selective inlet conditioners required.”
What Sets TSI DustTrak Apart
Most dust monitors give you a single number. The TSI DustTrak™ DRX gives you the full picture — simultaneously measuring multiple particle size fractions in real time. No other monitor on the market does this without additional hardware.

| PM1 | PM2.5 | Respirable | PM10 | PM Total |
Built for Every Environment
Whether you are conducting occupational hygiene surveys on a worksite, investigating indoor air quality in a commercial building, or running emissions monitoring for environmental compliance, the DustTrak family has a model suited to your application:
- Industrial / occupational hygiene surveys
- Indoor air quality investigations
- Outdoor environmental and emissions monitoring
- Point source and engineering control evaluations
- Remote and process monitoring
- Baseline trending, screening and aerosol research
During haze season, the use cases multiply. Facility managers need to know whether air filtration systems are performing. EHS teams need documentation to support decisions on outdoor work restrictions. Environmental consultants need reliable data to back their assessments. The DustTrak delivers on all fronts.
Don’t Wait for a Health Advisory to Act
The haze we are experiencing today is a reminder that air quality events can escalate quickly and without warning. The organisations that are best protected are those that already have monitoring systems in place — not those scrambling to react after the fact.
The TSI DustTrak™ II and DRX Aerosol Monitors put accurate, real-time data in your hands — so you can make confident, evidence-based decisions for your people and your operations, regardless of what the wind brings in.
