What MOH Advises During the Haze

Here’s a summary of MOH’s haze advisory (updated 17 Oct 2026). It’s general guidance, not medical advice. If you feel unwell, see a doctor. Per MOH: persons who are not feeling well, especially the elderly and children, and those with chronic heart or lung conditions, should seek medical advice.

Two numbers, two jobs:

• 1-hr PM2.5: for what you’re doing now, such as heading out in the next hour.
• 24-hr PSI forecast: for planning tomorrow.

Right now (1-hr PM2.5), per MOH’s personal guide:

1-hr PM2.5 (µg/m³)	Healthy people	Vulnerable people*
Band 1, Normal (0–55)	Continue with normal activities	Continue with normal activities
Band 2, Elevated (56–150)	Reduce strenuous outdoor activity for the next hour	Avoid strenuous outdoor activity for the next hour
Band 3, High (151–250)	Avoid strenuous outdoor activity for the next hour	Avoid all outdoor activity for the next hour; may wear a mask to reduce exposure
Band 4, Very High (251 and above)	Minimise all outdoor activity for the next hour; may wear a mask to reduce exposure	Avoid all outdoor activity for the next hour; may wear a mask to reduce exposure

*Vulnerable people such as the elderly, pregnant women and people with chronic heart or lung disease (MOH also groups children with the elderly and pregnant women in its PSI advisory). MOH says the guide isn’t meant to be prescriptive.

Planning tomorrow (24-hr PSI forecast), per MOH:

24-hr PSI forecast	Healthy people	Elderly, pregnant women, children	Chronic lung or heart disease
Good / Moderate (0–100)	Normal activities	Normal activities	Normal activities
Unhealthy (101–200)	Reduce prolonged or strenuous outdoor exertion	Minimise prolonged or strenuous outdoor exertion	Avoid prolonged or strenuous outdoor exertion
Very Unhealthy (201–300)	Avoid prolonged or strenuous outdoor exertion	Minimise outdoor activity	Avoid outdoor activity
Hazardous (above 300)	Minimise outdoor activity	Avoid outdoor activity	Avoid outdoor activity

Wording from MOH’s haze page, which can be updated during haze episodes, so check it for the latest.

Other points from MOH:

• Healthy people: short-term exposure over a few days generally won’t cause major health issues beyond eye, nose and throat irritation. Unless PM2.5 is in Band 4 or the PSI forecast is Hazardous, MOH says it’s generally safe for healthy people to carry on with outdoor activities in most cases, at reduced intensity or duration.
• Drink plenty of water.
• Chronic heart or lung conditions: keep your medication on hand.
• N95 masks: not needed for commuting between home and school or work, or indoors.

Free help from the government:

• Free N95-equivalent masks (one pack of two) for eligible Singaporeans (People’s Association page updated 16 Oct; CNA 15 Oct):
  • Vending machines at 37 transport hubs and Social Service Offices take an NRIC scan and serve only Pioneer and Merdeka Generation, CHAS Orange and Blue, Medical Fee Exemption Card holders and ComCare clients.
  • PA venues only: pregnant women, children aged 7–16 and people with conditions like asthma collect at PA venues, with proof or a self-declaration. Kids’ sizes are only at PA venues.
  • Check collection points on HazeMaskGoWhere. Don’t rely on live stock claims from third-party pages; confirm on site.
• Air-conditioned haze shelters at selected community clubs and residents’ committee centres. See the People’s Association list.
• The Haze Subsidy Scheme, active from 12 Oct 2026 (MOH, 11 Oct), at participating Public Health Preparedness Clinics (PHPCs) and polyclinics:
  • At PHPCs: Singapore Citizens aged 18 or under or 65 and over, plus Public Assistance, Pioneer and Merdeka Generation, CHAS Blue and Orange, and Medical Fee Exemption Card holders.
  • At polyclinics: all Singapore Citizens.
  • Fees: free for Public Assistance; up to S$5 for Pioneer and Merdeka Generation; up to S$10 for others.
  • Covers haze-related conditions such as asthma, rhinitis, bronchitis, conjunctivitis, COPD and URTI.

Air Purifier: Our Buy-Now Pick

NEA says portable air purifiers can further reduce indoor particle levels, but they work best in a closed room. Our buy-now pick below is the Blueair PetAir Pro P3i — still orderable from Blueair Official Store on Shopee Mall when we rechecked on 17 Oct 2026 (7pm SGT). Several other options, including the Dreame TP10, had moved to pre-order or sold out.

Before you look at brand room-size claims: brands calculate room size in different ways, so the figures aren’t comparable across brands. For haze, use the CADR sizing method further down instead.

Quick picks

Pick	Best for	Manufacturer-stated CADR	Fits our ~5× m³/h rule for (2.6 m ceiling)
Blueair PetAir Pro P3i	Mid-size rooms / pets	Smoke 175 CFM (AHAM); ≈297 m³/h (our conversion: 175 × 1.699)	up to ~22 m²

About Dreame’s PCADR: PCADR is Dreame’s particle figure; it isn’t the US AHAM smoke CADR that NEA’s rule uses, so treat our room sizing as a rough guide.

Sold out when we checked (17 Oct 2026): worth watching

Acerpure Pro P2 (AP551-50W): official CADR 324 m³/h and a 4-in-1 HEPA13 stack — a strong bedroom or small-living pick when stock returns. Existing owners can still buy the genuine ACF173 filter below.

EuropAce EDH5251BWH WIFI (25L + HEPA13): a 25L dehumidifier with standalone HEPA13 filtration for damp and haze together. EuropAce does not publish a CADR, so we never sized it for haze rooms. Not a substitute for a CADR-rated purifier for haze. It has an ioniser mode — see our ozone note under HEPA vs extras below.

Dreame TP10: on pre-order on Shopee and Dreame SG when we checked (17 Oct 2026, 7pm SGT). Official PCADR 280 m³/h (Dreame). PCADR is Dreame’s particle figure; it isn’t the US AHAM smoke CADR that NEA’s rule uses, so treat our room sizing as a rough guide.

Dreame Air Purifier TP20: official PCADR 500 m³/h and an H13 3-in-1 filter — living-room class when the variant is buyable again. PCADR is Dreame’s particle figure; it isn’t the US AHAM smoke CADR that NEA’s rule uses, so treat our room sizing as a rough guide.

Sold out? What to do

• Several popular models are on pre-order on the brands’ Singapore sites (for example Levoit and Sterra as of 17 Oct 2026). Ask for an ETA: a confirmed date may beat paying more elsewhere.
• Check the official channels. That means the brand’s own SG website and its official or Mall store on Shopee, not just one listing.
• Don’t overpay resellers. Haze-season markups happen, and unofficial sellers may ship units without a local warranty or with a non-local plug.
• Size any alternative properly. If your first choice is gone, use the CADR rule below to check the replacement is big enough for your room.
• In the meantime: close windows, run the aircon and wet-mop (see NEA’s home tips below).

Size it by CADR, using NEA’s rule (not the box’s room size)

CADR (Clean Air Delivery Rate) tells you how much filtered air a purifier delivers. Higher means it cleans a room faster.

For haze, NEA’s guidance says to look at the smoke CADR, and that it should be at least 3 times the room’s volume in cubic metres. NEA’s own worked example shows the CADR in that rule is measured in cubic feet per minute (cfm), the unit on the US AHAM label.

Most brands in Singapore quote CADR in m³/h instead, so we’ve converted it below (1 cfm ≈ 1.7 m³/h). That works out to roughly 5 × your room volume, in m³/h.

How to work it out:

• Measure your room: length × width × ceiling height = volume in m³.
• Multiply by 3 for the NEA minimum in cfm, or by about 5 for m³/h.

Our estimates for some example room sizes (these assume a 2.6m ceiling; measure your own):

Example room	Floor area	Volume	NEA minimum smoke CADR	≈ in m³/h
3m × 3m small bedroom	9 m²	23 m³	70 cfm	~120 m³/h
3m × 4m bedroom	12 m²	31 m³	94 cfm	~160 m³/h
4m × 4m master bedroom	16 m²	42 m³	125 cfm	~210 m³/h
4m × 5m large bedroom	20 m²	52 m³	156 cfm	~265 m³/h
5m × 6m living room	30 m²	78 m³	234 cfm	~400 m³/h
6m × 7m living/dining	42 m²	109 m³	328 cfm	~560 m³/h

Two caveats:

• Not every brand uses the same test. Brands calculate room size in different ways, and CADR labels may say particle, smoke or another test. NEA itself notes that many effective purifiers don’t have CADR ratings, and suggests getting the manufacturer’s data behind any filtration claim.
• Close the windows. CADR maths assumes an enclosed room. With the windows open during haze, no purifier will keep up.

Rated CADR is always at top speed. If you want it to run quietly at night, buy one with headroom above the minimum.

HEPA is what matters for haze; carbon is for smells

• True HEPA (H13/H14): captures fine particles such as PM2.5, dust and pollen. Our buy-now pick above uses a HEPA filter.
• Activated carbon: helps with smells and some gases (cooking, new-furniture odours). HEPA alone doesn’t do this.
• Ionisers and UV: extras on some models. If a model has an ioniser, check whether you can switch it off and what the brand says about ozone.

Running costs: electricity and filters

• Electricity: Blueair lists about 36 W for the PetAir Pro P3i. Check the label of whichever model you buy.
• Filters: these are the main ongoing cost. The Straits Times’ haze-season buying guide suggests HEPA filters typically need replacing every 6–12 months, and carbon filters every 3–12 months, depending on use. Follow the replacement indicator or the manual for your model.
• Third-party filters: search results for most models are full of “compatible” filters. They may be cheaper, but they aren’t made by the brand, and fit and filtration can vary. If filtration matters to you (e.g. allergies), go with the official filter from the brand’s store.

Climate Vouchers: air purifiers aren’t eligible

Lots of people search for “air purifier climate voucher”. The programme’s official list of eligible products (last updated 13 July 2026) has 12 types:

• Air-conditioners, fridges, washing machines and water heaters
• DC fans and LED lights
• Taps, shower fittings and water closets
• Clothes dryers and induction stoves, both new in 2026

Air purifiers aren’t on it.

You may see some retailers offer a “with Climate Voucher” option or voucher bundles. Those vouchers are for other, eligible items. Only products on the official eligible list qualify.

Climate Vouchers are redeemed at participating retailers’ physical stores (the FAQ says online transactions aren’t supported), so not on Shopee.

Genuine Replacement Filters

The filter does the actual work. During heavy haze it may clog sooner than usual, so follow your purifier’s filter indicator and its manual. Buy a genuine filter that names your exact model.

Blueair PetAir Pro P3i: genuine PetAir Pro Replacement Filter (H13 HEPA media stack). Buy from Blueair or an authorised store.

Dreame TP10: use the genuine Dreame H13 3-in-1 filter for the TP10 (pre-filter / HEPA / carbon). Buy from Dreame’s official SG store or an authorised seller — confirm the pack names TP10.

N95 Masks (and Equivalents)

When MOH says a mask helps:

• Band 4 (Very High): healthy people who must be outdoors may wear a well-fitted N95.
• Band 3 (High): the elderly, pregnant women and people with chronic heart or lung disease should avoid outdoor activity, but may wear one if they need to be outdoors.

Fit matters. MOH says an N95 must fit properly, covering the nose and mouth with a good seal.

Who should check first:

• The elderly, pregnant women and people with severe heart or lung problems who have difficulty breathing should consult a doctor before using an N95.
• Women in the 2nd or 3rd trimester shouldn’t use one for long periods.
• Take a break if it feels uncomfortable.

Reusing masks: MOH says N95 masks can be reused but shouldn’t be shared. Change yours when it’s soiled or out of shape.

Equivalent masks: MOH lists KN95, FFP2 and KF94 as equivalent to N95 and effective in reducing exposure to haze particles.

Surgical masks: MOH says these aren’t effective at filtering fine particles, though they can reduce discomfort from larger irritant particles.

Young children: there are no international standards for children’s masks. MOH says the AIR+ Smart Mask can be used, only where necessary, by children without heart or lung conditions, if it keeps a well-fitted seal.

Where to get masks:

• Free N95-equivalent masks (one pack of two) for eligible Singaporeans (PA page updated 16 Oct; CNA 15 Oct):
  • Vending machines at 37 transport hubs and Social Service Offices take an NRIC scan and serve only Pioneer and Merdeka Generation, CHAS Orange and Blue, Medical Fee Exemption Card holders and ComCare clients.
  • Pregnant women, children aged 7–16 and people with conditions like asthma collect at PA venues only, with proof or a self-declaration. Kids’ sizes are only at PA venues.
  • Check collection points on HazeMaskGoWhere. We don’t claim live stock figures for that page.
• Pharmacies: MOH says N95 masks are generally available at Guardian, FairPrice/Unity and Watsons, in store and online.

Wherever you buy, check the certification on the pack (for N95, look for NIOSH approval), and skip “N95-style” masks that show no certification.

PM2.5 Air Quality Monitors: Handy, but Not Official

A home PM2.5 monitor can show whether your bedroom air is improving with the windows shut and the purifier on. Keep expectations realistic:

• Readings may be off. The US EPA notes that low-cost air sensors may be inaccurate, may need calibration, and that high humidity (Singapore has plenty) can cause inaccurate readings.
• Watch the trend, not the exact number. It’s more useful to see readings fall than to compare them with NEA’s.
• For outdoor decisions, use NEA’s 1-hr PM2.5 readings. Not your home gadget.

If you buy one, choose a known brand from an official store, and check that it measures PM2.5.

At Home: What NEA Recommends

From NEA’s practical tips on reducing haze particles indoors:

• Close doors and windows when outdoor air quality is unacceptable, and re-open them when it improves. A closed room can build up heat and carbon dioxide, so air it out when readings drop.
• Stay indoors and reduce physical activity.
• Wet-clean (mop or wipe) to remove settled dust.
• Use fans or air-conditioners for circulation and cooling. If your air-conditioner draws unfiltered outdoor air (e.g. window units), close the outdoor air intake.
• Run a portable air purifier to further reduce indoor particles.

Aircon tip: keep your aircon filters clean, as your unit’s manual recommends. If it’s due for servicing, see our aircon servicing guide.

Optional: a DIY fan filter (read the safety notes first)

What the research says: US EPA research found that DIY air cleaners, made by attaching MERV 13 air filters to a box fan, can effectively reduce smoke particles in a laboratory setting. Designs with a cardboard shroud and multiple filters worked better.

What NEA says: NEA’s 2014 haze tips mention installed fan-filter ventilators using MERV 13 or F7 filters.

Safety notes:

• EPA recommends newer box fans with safety features: in the US, models from 2012 onwards with fused plugs and thermal cut-offs.
• Only use a fan with overheat protection (thermal cut-off); if you can’t confirm it has one, don’t build this. US-style box fans with those safety features are rare here.
• Keep the fan clear of obstructions.
• EPA says it can’t guarantee its safety findings apply to every fan or design. Its tests used US fans, so use a fan meant for Singapore’s mains power.
• Our advice (not EPA’s): don’t leave it running unattended.
• Check the filter daily during haze, and change it when it turns dark or smells of smoke.

It’s a stopgap, not a replacement for a properly sized purifier.

Pharmacy Basics

• Heart or lung condition: MOH advises keeping your medication on hand.
• Drink plenty of water, per MOH.
• Irritated eyes, nose or throat: MOH says these symptoms from short-term exposure are expected to resolve once you’re away from the haze. For irritated eyes, ask a pharmacist what suits you. See a doctor if symptoms are severe or don’t go away.

Buying During 11.11

11.11 falls in the middle of the haze. If you’re planning to buy a purifier, filters or masks then:

• Don’t wait for the sale if you need it now. Haze stock can run out before 11.11.
• Screenshot prices a week or two ahead, so you can tell whether the “discount” is real.
• Check that vouchers apply. Some exclude certain shops.
• Factor in filter costs. A cheap unit with expensive filters isn’t a bargain.

For voucher stacking and spotting fake discounts, see our Shopee 11.11 2026 guide.

Haze FAQ

What’s the PSI today?

Check haze.gov.sg or the myENV app for live hourly readings.

Should I look at PSI or PM2.5?

MOH says to use the 1-hr PM2.5 reading for immediate activities, and the 24-hr PSI forecast to plan the next day.

Do I need an N95 mask to go to work or school?

No. MOH says N95 masks aren’t needed for commuting between home and school or work, or indoors.

Are KF94 or KN95 masks OK instead of N95?

Yes. MOH lists KN95, FFP2 and KF94 as equivalent to N95 and effective in reducing exposure to haze particles. Check for the certification on the pack.

Can children wear N95 masks?

There are no international standards for children’s masks. MOH says the AIR+ Smart Mask can be used, only where necessary, by children without heart or lung conditions, if it keeps a well-fitted seal.

Where can I get free N95 masks?

Eligible Singaporeans can collect free N95-equivalent masks (one pack of two) (PA page updated 16 Oct; CNA 15 Oct). Vending machines at 37 transport hubs and Social Service Offices take an NRIC scan and serve only Pioneer and Merdeka Generation, CHAS Orange and Blue, Medical Fee Exemption Card holders and ComCare clients. Pregnant women, children aged 7–16 and people with conditions like asthma collect at PA venues only, with proof or a self-declaration; kids’ sizes are only at PA venues. See HazeMaskGoWhere for collection points (we don’t claim live stock figures).

Do air purifiers help with haze?

NEA says portable air purifiers can further reduce indoor particle levels. They may not perform as rated unless doors and windows are closed, so size yours by CADR.

What CADR do I need for my bedroom?

NEA’s rule is that smoke CADR (in cfm) should be at least 3 times the room volume in m³. For a 3m × 4m room with a 2.6m ceiling, that’s about 94 cfm, or roughly 160 m³/h (our calculation).

The purifier I wanted is sold out. What now?

Ask the official store for an ETA, check the brand’s own SG site, avoid overpriced resellers, and use the CADR rule to size any alternative. Several popular models (for example Levoit and Sterra) are on pre-order on the brands’ Singapore sites as of 17 Oct 2026. When we rechecked that evening (7pm SGT), the Acerpure Pro P2, EuropAce EDH5251BWH and Dreame TP20 were sold out or unavailable, and the Dreame TP10 was on pre-order on Shopee and Dreame SG — watch those pages, or buy the Blueair PetAir Pro P3i above if it still has stock.

Can I use Climate Vouchers for an air purifier?

No. Air purifiers aren’t on the official list of eligible products, even if a retailer offers a “with Climate Voucher” option.

How often should I change the filter during haze?

Follow your model’s indicator or manual. As a rough guide, the Straits Times suggests HEPA filters every 6–12 months, and filters may need replacing sooner during haze.

---

Bottom Line

• Check readings first. Look at the 1-hr PM2.5 on haze.gov.sg before heading out, and the PSI forecast for tomorrow.
• At home: close up, run the aircon, and use a properly sized purifier in the room you sleep in.
• Buying a purifier: buy from official stores, and check the ETA and stock if demand is high.
• Masks: keep a few well-fitting N95s (or KN95/FFP2/KF94) for when you must be outdoors at high PM2.5. Vulnerable groups should check with a doctor first.
• Get help if you need it: collect free masks if eligible, and see a doctor if you feel unwell.
