On the evening of August 31, air quality in parts of Metro Manila plunged to “Acutely Unhealthy” levels, according to ABS-CBN News. The culprit isn’t the usual traffic smog — it’s haze drifting all the way from forest fires in Kalimantan, Indonesia, carried across the equator by an unusual wind pattern.
If the sky has looked unusually gray this week or your eyes have been stinging on your commute, you’re not imagining it. Here’s what the data shows, and what you can do at home while the haze clears.
Just How Bad Is It?
The DENR-Environmental Management Bureau’s Air Quality Index (AQI) readings, based on fine particulate matter (PM2.5) concentrations, painted an alarming picture as of 7 p.m. on August 31:
- Parañaque (Don Bosco): AQI 270 — Acutely Unhealthy
- Las Piñas: AQI 205 — Acutely Unhealthy
- Manila: AQI 198 — Very Unhealthy
- Malabon, Valenzuela, Quezon City (Ateneo), Taguig, Marikina, San Juan, Muntinlupa, Pasay, and Mandaluyong: AQI 162–186 — Very Unhealthy
- Pateros, Navotas, and Makati: AQI 108–133 — Unhealthy for Sensitive Groups
PM2.5 refers to particles so tiny they can slip past your body’s natural defenses and settle deep in your lungs. Children, seniors, pregnant women, and anyone with existing heart or lung conditions are especially at risk.
“Stay Indoors” Isn’t Enough If Your Indoor Air Isn’t Clean
Quezon City has already issued an Air Quality Advisory, urging vulnerable residents to wear masks outdoors and stay inside as much as possible. That’s good advice — but haze and fine dust don’t stop at your front door. PM2.5 particles are small enough to seep in through gaps in windows and doors, aircon vents, and every time the door opens.
Worse, a standard vacuum can work against you indoors: many models trap larger debris but exhaust the finest, most dangerous dust right back into the air you’re breathing.
How the Rainbow Can Help You Ride Out the Haze

This is exactly the kind of situation the Rainbow Cleaning System was built for. Instead of a bag or filter that can recirculate fine dust, the Rainbow uses water as its filtration medium.
- Traps fine dust, not just debris: As you clean, dust and soot are pulled through water instead of a bag — you’ll often see the water darken, a visible sign of what would otherwise get pushed back into your air.
- Keeps indoor air moving cleaner: With outdoor air compromised, every pass indoors matters more. Regular use helps reduce the dust and airborne particles settling on your floors, furniture, and vents.
- No recirculated exhaust: Unlike bagless vacuums that can blow fine particulate matter straight back into the room, the Rainbow’s water basin is designed to hold onto what it collects.
You can also add a few drops of Rainbow fragrance — Eucalyptus is a popular pick — to the water basin, so your home feels fresh even while the windows stay shut.
Protect Your Family While You Wait It Out
Experts say the haze may persist for several more days. While it clears, the most control you have is over the air inside your own home.
