Singapore's National Environment Agency said on that the 24-hour PSI in the south and north fell to the good-moderate range, while other regions remained unhealthy but showed a downward trend. Earlier that day, the agency noted that hourly PM2.5 levels stayed within normal limits across all regions, and tests in homes indicated indoor concentrations could exceed outdoor levels, with air purifiers reducing pollutants more effectively than air-conditioners and some expired N95 masks still meeting filtration standards.

    It’s good the PSI is improving in some areas, but I keep thinking about those still stuck with unhealthy air—and indoors no less. Not everyone can afford air purifiers or quality masks, so who’s really bearing the brunt of this haze? That’s the gap that needs more attention.
