Wah, the skies look hazy again. But do you really need to wear an N95 mask?

Haze in Singapore can bring more than just a smoky-looking sky. Fine particles such as PM2.5 can enter the respiratory system and may cause throat irritation, watery or irritated eyes, a runny nose, coughing and breathing discomfort.

Singapore has experienced periods of elevated haze and PM2.5 levels in September 2026, with NEA advising residents to check both the 1-hour PM2.5 reading and 24-hour PSI forecast when planning outdoor activities.

But here's the important part:

You don't necessarily need to wear an N95 every time the air looks hazy.

When Should You Wear an N95 Mask?

The right level of protection depends on the air quality, how long you will be outdoors and how strenuous your activity is.

🚶 Short outdoor trip?

For a normal short trip outdoors, an N95 mask is generally not necessary for healthy individuals.

🏃 Outdoors for several hours?

If air quality becomes severely polluted and you need to spend several hours outdoors, a properly fitted N95 respirator can help reduce exposure to fine particles.

Singapore's Ministry of Health specifically advises that healthy individuals who need to be outdoors for several hours when the PSI is above 300 (Hazardous) may reduce exposure by wearing a well-fitting N95 mask.

👨👩👧 More vulnerable individuals?

Children, elderly persons, pregnant women and people with existing heart or lung conditions should take extra care during haze periods. Those with severe heart or lung conditions should consult their doctor about whether an N95 is appropriate if prolonged outdoor exposure is unavoidable. 

What Are the Health Effects of Long-Term Haze Exposure?

The concern isn't just about one hazy afternoon. If haze continues for several days, reducing your overall exposure to PM2.5 and other fine particles becomes more important.

PM2.5 particles are very small and can travel deep into the lungs. Long-term exposure to high levels of fine particulate pollution has been associated with increased risks of respiratory and cardiovascular health problems.

However, Singapore's haze episodes are generally intermittent rather than continuous, and the long-term health effects of Singapore's specific pattern of haze exposure are not yet fully established.

So, if the haze persists, the practical approach is to reduce your overall exposure rather than worry about wearing an N95 all the time.

Why Choose an N95 Instead of a Surgical Mask?

An N95 respirator is designed to filter airborne particles and, when properly fitted, provides a closer fit around the face.

A regular surgical mask is primarily designed for other purposes and does not provide the same level of filtration and fit for fine airborne particles.

The 3M™ 8210 N95 Particulate Respirator featured in our haze flyer is designed to filter at least 95% of airborne particles and is lightweight for everyday use.

It is also Made in Singapore.

What About When You're At Home?

You don't need to walk around your house wearing an N95.

Instead, focus on keeping your indoor air cleaner.

A HEPA air purifier can help filter airborne particles, while an activated carbon filter can help with certain odours and gaseous pollutants.

MEDPRO 3-in-1 Air Purification

Our MEDPRO air purifier uses a 3-in-1 filtration system:

1. Pre-Filter

Captures larger particles such as:

• Dust
• Pet hair
• Lint

2. H13 True HEPA Filter

Designed to capture very fine airborne particles, including particles associated with:

• PM2.5
• Pollen
• Bacteria
• Smoke

3. Activated Carbon Filter

Helps reduce unpleasant odours and certain gaseous pollutants.

A simple way to remember it:

Going outside for extended periods → N95 mask when appropriate

At home → Keep your indoor air clean

What Else Can You Do During Haze?

You don't have to panic when the PSI rises. A few simple steps can make a difference:

✅ Check the latest PSI and PM2.5 readings

NEA recommends checking the 1-hour PM2.5 reading for immediate outdoor activities and the 24-hour PSI forecast when planning ahead.

✅ Reduce prolonged outdoor activity

When air quality is unhealthy, reduce prolonged or strenuous outdoor exercise.

✅ Keep N95 masks at home

You don't want to be searching for masks only after the haze gets bad.

✅ Keep your air purifier running

Especially in enclosed rooms where you spend a lot of time.

✅ Keep your purifier filter maintained

A dirty or overdue filter may affect the performance of your air purifier.
