An air purifier is one of the easiest ways to keep your indoor air cleaner, especially now during Singapore’s haze season.
While limiting outdoor activities and keeping your windows closed can reduce your exposure to haze, an air purifier provides an extra layer of protection by removing particles that have already entered your home.
However, with so many models available, choosing the best air purifier in Singapore isn’t always straightforward. Brands such as Dyson, Sterra, Philips, and Xiaomi offer different filters, features, and prices, making it hard to know which is worth buying.
In this guide, we compare the best air purifiers in Singapore, including our top picks for haze, pets, allergies, and everyday home use. We’ll also explain what to look out for when choosing an air purifier, so you can find one that suits your needs and budget.

What Is an Air Purifier and How Does It Work?
An air purifier is an appliance that removes airborne pollutants such as dust, pollen, smoke, and haze particles.
It works by drawing indoor air through a filtration system before releasing the filtered air back into the room.
Most home air purifiers use three layers of filtration:
- Pre-filter: a mesh that catches large particles such as hair, pet fur, and lint, which helps the main filter last longer.
- HEPA filter: a dense fibre filter that traps fine particles, including PM2.5 (tiny airborne particles that are 2.5 micrometres or smaller) from haze, dust, pollen, mould spores, and pet dander. A true HEPA filter captures at least 99.97% of such particles.
- Activated carbon filter: absorbs certain gases and odours, including some cooking smells and volatile organic compounds (VOCs).
Some air purifiers also include additional features such as UV-C lights to destroy airborne microorganisms or sensors that automatically adjust fan speed.
Why Your Aircon Isn’t Enough to Protect You From Haze
Although air conditioners have filters, they are generally designed to trap larger particles such as dust and lint.
However, haze contains tiny airborne particles known as PM2.5. These particles are much smaller than the width of a human hair and can pass through many standard air-conditioner filters.
When inhaled, these tiny particles can travel deep into your lungs and even enter your bloodstream, potentially affecting your overall health. Studies have shown that exposure to PM2.5 can lead to heart and lung disease, as well as increased risk of cardiopulmonary conditions and lung cancer.
This is where an air purifier comes in. A high-efficiency air purifier filter can trap these particles and reduce their concentration in your indoor air.
Other reasons to get an air purifier:
- Less dust: Singapore homes collect fine dust from traffic, construction, and open windows. A purifier catches it while it’s still floating in the air.
- Fewer allergy and asthma triggers: HEPA filters trap common triggers like dust mites, pollen, and mould.
- Pet-friendly homes: the filters catch fur and tiny flakes of skin pets shed, and the carbon filter helps reduce pet smells.
- Post-renovation: a purifier with a carbon filter helps clear the smell of new paint, carpentry, and furniture.
Tips for using your air purifier during the haze:
- Keep it running all day while the PSI is unhealthy. If it has an auto mode, use it.
- Put it in the bedroom first, since that’s where you spend the most hours at a stretch.
- Keep doors and windows shut. If you have a window aircon, close its fresh air vent.
- Wipe and mop instead of dusting or sweeping, so settled particles don’t get kicked back into the air.
Best Air Purifiers in Singapore
Here are our picks for the best air purifiers.

What to Look Out For in an Air Purifier
When buying an air purifier, focus on how well it cleans the air, whether it fits your room size, and how much it costs to maintain.
You don’t necessarily need the most expensive model. An affordable air purifier with a good filter and enough cleaning power for your room may be all you need.
Here are some things to consider.
1. HEPA Filter: Look for Effective Filtration
As mentioned above, a HEPA filter is designed to trap very small airborne particles, including dust, pollen, and haze particles.
When shopping for air purifiers, keep an eye out for those with these labels:
- True HEPA filters
- H13 HEPA filters (Medical-grade)
- H14 HEPA filters (Higher filtration level medical-grade)
Be wary of terms such as “HEPA-type”, “99% HEPA”, or “HEPA-like” as these are just marketing terms.
They aren’t properly certified like true HEPA filters and therefore don’t meet the same rigorous testing standards.
2. CADR
CADR stands for Clean Air Delivery Rate, and it tells you how much air a purifier can clean per hour.
The higher the CADR, the faster it cleans your room.
For example, a purifier with a CADR of 400 m³/h can generally clean a room faster than one rated at 200 m³/h, assuming both are tested under comparable conditions.
3. Room Size: Make Sure It’s Suitable for Your Home
Most air purifiers come with a recommended room size.
For example, a compact air purifier may be sufficient for an HDB bedroom but struggle to clean a spacious living room quickly.
If you’re buying an air purifier mainly for haze protection, choose one that can comfortably handle your room size rather than a model that’s just barely large enough.
4. A Carbon Filter for Smells
A HEPA filter traps particles but not smells. If you want to get rid of the burning smell of haze, cooking smells, or the chemical smell from new paint and furniture, pick a model with a good carbon filter.
5. Noise Level
Some air purifiers can get quite noisy when operating at full speed.
If you’re placing one in your bedroom, look for a model with a quiet or sleep mode. As a rough guide, noise levels of around 20 to 30 dB are very quiet and are considered ideal for sleeping, reading, or a quiet environment.
However, keep in mind that sleep mode usually reduces fan speed, so the purifier may clean the air more slowly.
6. Additional Features
Many newer air purifiers come with convenient features that make them easier to use.
For example, some models display your room’s air quality, automatically adjust fan speeds, or let you control settings through a mobile app.
7. After-Sales Support
Check how long the warranty is, whether replacement filters are easy to buy in Singapore, and whether the brand has a local service centre.
Air Purifier vs Humidifier vs Dehumidifier: What’s the Difference?
| Feature | Air purifier | Humidifier | Dehumidifier |
| Main purpose | Traps haze, dust, pollen, and pet fur; a carbon filter also removes smells | Adds moisture to dry air | Removes excess moisture from damp air |
| Removes haze particles? | Yes, with a true HEPA filter | No | Yes, only if it has a HEPA filter |
| Best for | Haze, dust, allergies, pets | Dry skin or throat in air-conditioned rooms | Mould and mildew, musty smells, drying laundry |
Conclusion
The best air purifier in Singapore depends on your budget, room size, and the airborne pollutants you want to remove.
Whichever model you choose, focus on its filtration performance, cleaning power, and suitability for your room rather than paying extra for features you might not need.
An air purifier is also just one part of keeping your home comfortable and clean. Consider pairing it with one of the best robot vacuums in Singapore to remove dust that settles on floors, or explore our HDB renovation tips to learn more about improving your living space.

Frequently Asked Questions
Do Air Purifiers Really Work for Haze?
Yes. Air purifiers with a true HEPA filter trap at least 99.97% of tiny particles, including the fine smoke particles in haze. They work best in a closed room, with a purifier powerful enough for the room’s size.
What CADR Do I Need for My Room?
As a rule of thumb, aim for at least 150 m³/h for a common bedroom (about 100 to 120 sq ft), 200 m³/h for a master bedroom (about 140 to 170 sq ft), and around 400 m³/h for a living room (320 sq ft or more). A higher CADR generally means faster air cleaning.
Can an Air Purifier Remove Dust?
Yes. A HEPA filter captures airborne dust, and a pre-filter catches larger particles and fur.
However, it cannot remove dust that has already accumulated on your floors, shelves, or furniture. You’ll still need to vacuum and clean regularly.
Do I Need an Air Purifier With a Humidifier in Singapore?
Usually not. Singapore is humid all year, so extra moisture is rarely needed and can encourage mould. A humidifying purifier is only worth it if your bedroom feels very dry from running the aircon for long hours.
