Air Purifier Singapore: What to Buy During the Haze
If you’ve been searching for an air purifier in Singapore this week, you’re not the only one.
Singapore’s haze situation has worsened sharply in recent days. On 14 October, hourly PM2.5 readings in western Singapore surged into the Very High band, while the 24-hour PSI subsequently reached the Very Unhealthy range in the west.
According to the National Environment Agency (NEA) , dense smoke haze from fires in Kalimantan was being carried towards Singapore by prevailing winds.
Unsurprisingly, demand for air purifiers has jumped.
And in some places, stock is already getting difficult to find.
Air Purifiers Are Selling Out Across Singapore
The increase in demand has been significant.
According to The Straits Times , Courts saw air purifier sales rise sharply as haze conditions worsened, while other major electronics retailers also reported significantly stronger demand.
CNA also reported that some retailers had sold out of selected air purifier models, with stores receiving a surge in customer enquiries.
The increase in demand has even affected online prices.
CNA reported that some air purifiers listed by resellers were being offered at substantially higher prices than their official retail prices as availability tightened.
So if you are buying an air purifier because of the haze, the urgency is understandable.
But that does not mean you should buy the first purifier you can find.
What Should You Actually Look for in an Air Purifier for Haze?
During haze, one of the main pollutants to pay attention to is PM2.5.
PM2.5 refers to fine particulate matter measuring 2.5 micrometres or smaller. These particles can also make their way into indoor spaces, even when you spend most of your time at home.
That is where an appropriately sized air purifier can help.
NEA recommends highly efficient particle filtration such as HEPA filters when choosing an air-cleaning device for fine particles. But filtration grade is only one part of the equation.
You should also pay attention to:
- HEPA filtration
- Clean Air Delivery Rate (CADR)
- Recommended room coverage
- PM2.5 monitoring
- Replacement filter availability
- Whether the purifier is appropriately sized for your room
For haze, NEA recommends paying attention to smoke CADR where this measurement is available because it is particularly relevant to smoke particles.
You can read more about choosing an appropriate air-cleaning device in NEA’s air-cleaning device guidance .
In other words, a purifier with an impressive filter still needs to move enough air through that filter to clean your room effectively.
HEPA-13 or HEPA-14?
You may also see terms such as HEPA-13 and HEPA-14 when comparing air purifiers.
Both are high-efficiency particle-filtration grades.
Within the NNIO Air Purifier range , selected products use HEPA-13 filtration, while dedicated models such as NH14PRO and PET-PRO use HEPA-14 filtration.
NNIO’s HEPA-13 products are rated to capture up to 99.95% of airborne particles at the specified test size, while our HEPA-14 filtration is rated up to 99.995%.
But a higher HEPA number does not automatically mean a purifier is suitable for your space.
A better question is: how much air can the appliance clean, and is that enough for the room you are using it in?
That is why CADR and room coverage matter alongside filtration efficiency.
What If the Air Purifier You Want Is Sold Out?
This is where it helps to consider what you actually need from the appliance.
A dedicated purifier is not your only option.
NNIO also offers products that combine HEPA filtration with cooling or air circulation.
That means you can continue using them as everyday appliances even after haze conditions improve.
At the time of publishing, selected NNIO air-purifying products remain available online while stocks last.
ZENO Air Purifying Bladeless Fan
If you were already planning to buy a fan, ZENO gives you everyday airflow and filtration in one appliance.
ZENO combines a bladeless BLDC fan with HEPA-13 filtration, 12 speed settings and multiple operating modes.
This makes it particularly useful for bedrooms and living spaces where you want airflow as well as particle filtration.
Best for: People who need a fan anyway and want air purification built in.
AIRPRO Multi-Purpose Air Cooler
If cooling is your bigger concern, AIRPRO combines air-cooling functionality with HEPA-13 filtration.
It is designed as a multifunctional option for Singapore’s climate: everyday cooling with additional filtration built into the same appliance.
Best for: Homes looking for cooling plus additional air filtration.
TWISTER 7" BLDC Purifying Air Circulator
If you want something compact for a bedroom, study or smaller living space, TWISTER combines air circulation with HEPA-13 filtration.
Rather than taking up space with both a separate fan and purifier, TWISTER is designed to provide everyday airflow while filtering the air passing through the unit.
Key features include:
- HEPA-13 filtration
- 260m³/h CADR
- Approximately 207 sq ft purification coverage
- 12 fan speeds
- BLDC motor
- Automatic horizontal oscillation
- Filter-change reminder
Its smaller footprint also makes it a practical option if you are looking for filtration for a more compact room.
Best for: Bedrooms, studies and smaller spaces where you want air circulation and HEPA filtration in one appliance.
TWOPRO 2-in-1 Purifying Air Circulator
If you want stronger whole-room airflow, TWOPRO combines a BLDC air circulator with HEPA-13 filtration.
Its 3D oscillation moves air both vertically and horizontally, helping circulate filtered air around the room instead of simply blowing in one fixed direction.
Key features include:
- HEPA-13 filtration
- BLDC motor
- 7 fan speeds
- 3 operating modes
- Up-down and left-right 3D oscillation
- Real-time air-quality display
- Stated coverage of up to 516 sq ft
- Filter-change reminder
TWOPRO makes particular sense if you were already considering buying a fan or air circulator, because the same appliance can continue serving an everyday cooling function long after the haze clears.
Best for: Living rooms and shared spaces where you want stronger air circulation together with HEPA filtration.
2-in-1 Dehumidifier and Air Purifier
Singapore’s haze is not the only indoor-air challenge.
Our humid climate can also contribute to dampness, musty conditions and a more favourable environment for mould growth.
NNIO’s 2-in-1 Dehumidifier and Air Purifier combines moisture removal with a HEPA-11 filter, giving you two functions in one appliance.
It can help reduce excess humidity while filtering airborne particles as air moves through the unit.
Best for: Humid rooms, indoor laundry drying and homes that also want particle filtration.

Should You Wait for a Dedicated Air Purifier to Restock?
That depends on your priority.
If your main goal is specifically air purification during haze, it may make sense to choose a dedicated purifier with clearly stated filtration, CADR and room coverage.
For example, the NNIO NH14PRO HEPA-14 Air Purifier has a published 400m³/h CADR and recommended coverage of up to 520 sq ft.
It also includes PM2.5 monitoring and Auto Mode, making it a more dedicated option if purification is your main priority.
If, however, you also need a fan, air cooler or dehumidifier, choosing a multifunctional appliance with built-in HEPA filtration may make more sense than buying a product simply because it is the last purifier available.
The important thing is not to let urgency override the specifications.
Be Careful With Haze-Season Price Surges
With demand rising quickly, it is worth checking official retail prices before buying from resellers.
CNA reported substantial price increases on some online air purifier listings as stock tightened.
Before checking out, compare:
- Official retail price
- Filter replacement cost
- Warranty coverage
- CADR
- Recommended room coverage
- Availability of replacement filters
An expensive purifier is not automatically a better purifier.
And paying several times the usual retail price does not make the air cleaner any faster.
What Else Can You Do During the Haze?
An air purifier can help reduce indoor particulate levels, but it should be used alongside other practical measures.
NEA recommends using the 1-hour PM2.5 reading when making decisions about immediate activities and referring to the 24-hour PSI forecast when planning ahead.
Check the latest official readings through Haze.gov.sg or the myENV app.
At home, you can also:
- Keep doors and windows closed when outdoor air quality is poor
- Avoid activities that create additional indoor smoke or particles
- Wet-wipe or mop settled dust
- Run an appropriately sized air purifier consistently
- Check and replace filters when required
- Monitor official PM2.5 and PSI readings instead of relying only on visibility outside
Looking for an Air Purifier in Singapore? Don’t Just Buy Whatever Is Left
The current haze has created a very real rush for air purifiers.
But the same principles still apply.
Look for effective particle filtration, sufficient cleaning capacity for your room, clearly stated specifications and replacement filters that you can actually buy later.
If dedicated air purifiers are sold out, a suitable air-purifying fan, air cooler or dehumidifier may also be worth considering depending on what you need at home.
At the time of publishing, selected NNIO air-purifying products are still available while stocks last, including products that combine HEPA filtration with everyday cooling, air circulation or dehumidification.
Haze season may create urgency.
Your purchase does not have to be rushed.
