10 Best Air Purifiers in Singapore

Do we even need air purifiers in Singapore? Heck yes. Although we haven’t seen the haze in Singapore for quite a while now (thanks to our good neighbours), it seems there are worse pollutants these days threatening the air quality in our homes that call for air purifiers. Reports of formaldehyde poisoning and unsafe indoor levels of formaldehyde causing kids to fall sick have spiked in recent years, often traced back to low-cost plywood furniture, synthetic finishes, adhesives, and off-gassing from freshly renovated home interiors.

Innocuously dubbed “the new house smell”, this highly reactive and invisible gas isn’t just unpleasant or mildly toxic—it’s a known carcinogen linked to respiratory issues, skin irritation, and long-term health risks. Children, the elderly, and individuals with asthma or allergies are especially vulnerable. To make matters worse, formaldehyde is only one of many volatile organic compounds (VOCs) found in everyday items—from household cleaners to flooring and wall paint—all of which can accumulate in poorly ventilated spaces.

In modern Singapore homes where our windows stay shut most of the day due to the perennial heat, noise, or air-conditioning, airborne pollutants can quickly build up to unhealthy levels. That’s why air purifiers with HEPA and activated carbon filters are everyday essentials—they help trap not only dust and allergens, but also harmful VOCs, improving indoor air quality and offering a quiet but indispensable layer of protection for our families.

Sterra Moon True HEPA-13 Air Purifier, from $189

Best air purifier for allergy sufferers

One of the bestselling—and by inference—best air purifiers in Singapore is local brand Sterra’s Moon True HEPA-13 Air Purifier. Its medical grade HEPA-13 filter effectively helps with allergies, sinus, and asthma by filtering up to 99.97% of airborne nasties like dust mites, pet dander, pollen, spores, allergens and more. It also deals with harmful chemicals and VOCs, mould, bacteria and viruses.

With a CADR of 280m³/h and a coverage area of up to 615 sqft, the Sterra Moon should serve anything from a large master bedroom to a small apartment well. It also has a real-time air quality indicator that informs you of the room’s air quality by changing colour, a pre-filter and activated carbon filter, and a UV sterilisation or negative Ion function (you have to choose one or the other when buying your set).

At its lowest fan setting, you probably wouldn’t even hear it at 20 dB. Its sleek, compact appearance also doesn’t scream “appliance” from the corner, and its electricity consumption at 45 watts shouldn’t spike your utility bill too much. At this price, it’s no wonder the Sterra Moon sells so well—I have a good mind to try it next. You can even get a bulk discount when purchasing 2 or 3 units at once.

The Sterra filter costs $55, and needs replacing every 2,200 hours—which can be every 3-12 months depending on your usage. You can only buy these from Sterra, which I guess explains why the air purifier itself is so reasonably priced—they’ll earn it back on your repeated filter purchases. Enjoy a 10% discount by ordering it for $49.50 on a subscription basis.

Xiaomi Smart Air Purifier 4, $221

Best value-for-money smart air purifier

I am be a biased MiHome user (loyal long before the MiHome app was renamed Xiaomi Home), but I think Xiaomi offers the best smart feature bang for your buck. Over the years, proudly Chinese Xiaomi has built its name on solid, affordable tech, and the Smart Air Purifier 4 totally lives up to that reputation. It’s one of those purchases you might make expecting “good enough,” but it quickly became one of my favourite home gadgets. It’s surprisingly powerful for the price, and the sleek, minimalist design fits anywhere in my living room and bedrooms without drawing attention to itself.

The biggest draw for me is Xiaomi’s smart integration. It connects easily to the app and even works with Google Assistant and Alexa—I can control it from my phone, set schedules, and check air quality levels from anywhere in the world really. I have one unit in every bedroom (it’s rated for up to 48m² with a CADR of 400m³/h, and claims to purify a 20m² room in around 10 minutes), but I use the bigger and more powerful Pro version in my living room.

It features an efficient 360° all-round air intake, and it comes with a 3-in-1 filter system—which includes a True HEPA filter with 99.97% efficiency for 0.3 micron particles and an activated carbon layer that neutralises odours, formaldehyde, toluene and VOCs—I can attest the air smells fresh and clean minutes after running this. It also traps pet dander, pollen, and fine dust particles, and effectively reduces H1N1 and other viruses in the air. There’s a built-in laser sensor too that updates the PM2.5 levels in real time on its OLED screen, making it super satisfying to see the numbers drop after 10–15 minutes of running.

Power consumption is surprisingly low—only about 30 watts on max and a mere 1-2 watts on standby, which makes it incredibly energy-efficient even if you run it 24/7. It’s also pretty quiet at 32.1 dB in night mode, and lets you completely turn off its air quality indicator and display for more peaceful sleep. Filter replacements are widely available and cost about $38–$45, and they usually last 6–12 months depending on your air conditions and usage. Note: there are a lot of “compatible filters” on the market that cost less, but buy those at your own risk.

The Xiaomi Smart Air Purifier 4 is priced at $221 from Shopee and Lazada, and often goes on sale during big campaigns.

Dyson Purifier Big+Quiet Formaldehyde, from $1,299

Best premium air purifier for large living spaces

Okay—this one is a splurge, but if you’re looking for a top-of-the-line air purifier that looks like a designer fan while tackling pollutants and eliminating formaldehyde, the Dyson Purifier Big+Quiet Formaldehyde is hard to beat. I wouldn’t call this an “entry-level” choice by any means, but once you understand what it does, the price tag starts to make a little more sense.

This model is designed for extra-large spaces and projects air over 10 metres to purify the space—think living rooms with double-storey windows, open-concept layouts, or multi-room apartments. It features Dyson’s HEPA H13-grade filtration, which traps 99.95% of ultrafine particles down to 0.1 microns, including PM2.5, allergens, pet dander, bacteria, and up to 99.9% of viruses including COVID-19. But the real star here is its formaldehyde destruction capability. Unlike most purifiers that merely trap VOCs in activated carbon, this one has a catalytic filter that breaks down formaldehyde into harmless water and CO₂—and that tech doesn’t need replacing. If you’ve recently renovated or live with a lot of engineered wood or laminate, this matters more than you think.

Design-wise, it’s sleek and whisper-quiet. The “Big+Quiet” isn’t just branding — even on high settings, the sound stays at just 56 dB, thanks to Dyson’s cone aerodynamics. Instead of blasting air like a traditional fan, it uses precise, whole-room circulation that you can’t see but will definitely feel. There’s also a gorgeous curved display showing real-time air quality stats, and app integration via MyDyson, which lets you monitor and control everything remotely.

It’s certainly not a budget option, and filter replacements are on the pricier side ($89.99 for the activated carbon filter, and $169.99 for the HEPA filter), but get this—you only need to change the HEPA filter once every 5 years, and the activated carbon filter once every 2 years! How’s that for low maintenance? It’s also energy efficient given its size and capability, using a maximum of 50 watts. This is a hefty and handsome option—my only reservation stems from not finding its CADR stated anywhere.

Philips 600i Series AC0650/10 Air Purifier, from $132

Best compact HEPA air purifier for everyday use in small homes

Often touted for reliability, Philips air purifiers are often good long-term choices due to their dependable performance and affordable filter replacements. This is your everyday workhorse, because it strikes that sweet spot between reliability, performance, and affordability. This small, cylindrical unit looks great in any corner, and it’s especially suited for bedrooms, nurseries, or small living rooms (up to 44m² with a CADR of 170m³/h).

At this price, this thing does a lot. It captures 99.97% of particles as small as 0.003 microns (which is finer than standard HEPA)—great for allergy sufferers and any possible haze or seventh month burning. It also tackles pollen, dust mites, bacteria, and even airborne viruses. Its proprietary NanoProtect HEPA technology claims to attract pollutants with an electric charge and clean up twice more air than HEPA H13 filters. The only thing missing is an activated carbon layer, but this has a pre-filter.

It also works with the Philips Air+ app, so you can monitor and control your air purifier remotely. Sleep mode is quieter than a whisper at 19 dB, and its digital display also dims to minimise light disturbance. Power usage is low (max 12 watts) and filter replacements are reasonably priced at around $42 and can last up to 12 months with regular use, before the air purifier alerts you to replace it. All in all, an everyday winner.

The Philips 600i Series Air Purifier is priced at $132.20 on Amazon.sg and Lazada

IKEA UPPÅTVIND Air Purifier, $49

Best ultra-budget air purifier for small rooms

If you’re looking for the most affordable, no-frills air purifier on the market, IKEA’s UPPÅTVIND is an absolute hidden gem. At just $49, it’s hard to beat on price, and although it won’t replace a full-featured HEPA powerhouse, it does a surprisingly decent job at clearing up small spaces.

Optimised for rooms sized 7m² with a CADR up to 95m³/h, this would serve a small study room or kids’ bedroom well enough. It’s compact, super lightweight, and has a clean white design that blends in quietly. There are three fan speeds, no digital display, and no app controls—but it gets the basics right. The replaceable particle filter traps dust and larger airborne pollutants like cigarette smoke and pollen, making it a nice upgrade over a basic desk fan, especially if you’re dealing with mild allergies or just want to reduce visible dust.

Noise-wise, it’s fairly quiet on low, though you’d notice it on high (31-55 dB). There’s no ioniser or carbon filter here, so it won’t remove smells or formaldehyde, but that’s expected at this price. What’s good about it is the simplicity: one button, one filter, easy to use and clean. Power consumption is also very low (listed as a maximum 8 watts), and replacement filters are cheap and easy to install—only $8 each. If you’re trying to clean the air in a small bedroom, a home office, or even a dorm, this could be a good stepping stone before committing to something larger or more advanced.

The IKEA UPPÅTVIND air purifier is priced at $49 from IKEA Singapore.

Quair Plasma Mini, $140.30

Best wearable personal air purifier for travel and taking with you everywhere

Weighing in at 85g, the Quair Plasma Mini is a bit of a wildcard—and a bit of a cult favourite—particularly if you spend a lot of time in shared spaces, cars, or dusty cafes. I first came across it on social media and was sceptical at first because it’s super tiny. Like fits-in-your-hand tiny. I’ve honestly been wanting to try it since then but kept bumping it down my shopping list for fear it would just end up living in my unused tech drawer with all the other handheld electric fans and bought-on-a-whim gadgets. But one of my mummy friends who flies a lot with her baby swears by it.

It’s compact, sleek, available in cute colours like pink and white, and emits low-concentration ions to neutralise particulate matter, VOCs, odours and viruses including aerosolized human coronavirus. Instead of traditional HEPA filtration, it uses plasma ionisation technology, which is filterless and maintenance-free. It also distinguishes its tech from negative ionisation, using bipolar ionisation which neutralises airborne contaminants and transforms them into moisture instead of just weighing them down to the ground. If you remember what I mentioned about ozone byproducts, this ioniser meets international safety standards, producing low levels of ozone (0.008ppm) that fall well within EPA and FDA standards.

Honestly, this baby isn’t going to clean a room—just a 30cm radius—but if you suffer from mild sinus issues or hate stale air in your car or plane seat, this thing could feel like a small luxury. It’s also quiet and discreet, making it ideal for work desks, bedside tables, and travel pouches. It charges via USB-C and can last up to 10 hours on a single charge. No replacement filters, no app, no fuss—just clean-ish personal air wherever you go.

The Quair Plasma Mini is priced at $140.30 from Lazada.

Dreame PM10 Air Purifier, $799

Best air purifier for pet homes and VOC protection

Looking oddly familiar (think Dyson), the Dreame PM10 seems to be hugely popular among Singapore pet owners and HDB residents. Optimised for rooms sized 100m² with a CADR of 300m³/h, it uses a HEPA-13 filter to remove 99.97% of particles as small as 0.3 microns (dust, pollen, bacteria, etc.).

It also adds a 4-layer filtration system including a carbon layer and formaldehyde-catalysing filter, which is great for eliminating cooking smells or off-gassing plastics and furniture VOCs. Instead of simply filtering out formaldehyde, it is capable of “decomposing” and neutralising the gas into water and CO₂.

A standout feature is its air sweep angle: you can aim purified air forwards or upwards at 0°, 45°, 90°, or 180°, ensuring full-room coverage without any directional hotspots. If you have pets, handy functions like Pet Mode, UVC sterilisation (ultraviolet elimination of pathogens), and PlasmaNova sterilisation actively help sanitise the air by killing viruses, bacteria and germs.

Another handy and special feature is its Environment Detect technology which is able to detect human presence and automatically direct airflow to your position within a 5m, 120° range. Noise is acceptably low at 32 dB in Sleep mode, and you can control the purifier via its LCD panel, a smartphone app, remote or offline voice control. Electricity consumption isn’t publicised, nor is information about how often you’d need to change the HEPA carbon filter (which costs $99).

At $799, the Dreame PM10 isn’t exactly cheap, but its advanced filtration, smart airflow tracking, VOC neutralisation, and pet-friendly modes make it one of the most feature-packed purifiers available in Singapore. If you’re serious about clean air—especially in a household with pets or newly renovated interiors—it’s probably a smart long-term investment.

NNIO HEPA-14 air purifier (NH14PRO), $228

Best ‘medical grade’ HEPA-14 air purifier for homes

The NNIO NH14PRO air purifier stands out in Singapore as one of the rare HEPA-14 models at an affordable price point, offering even higher filtration than most rivals. With a CADR of 400 m³/h and a range of up to 520 sqft, it can refresh air in large living rooms and master bedrooms quickly. It’s also compact and lightweight (3.8 kg), making placement flexible should you need to move it between rooms.

While disclaiming to be “not certified or intended for medical use in healthcare settings”, its medical-grade H14 HEPA filter removes 99.995% of airborne particles as small as 0.3 microns—good enough for me! It also includes UV sterilisation and a negative ion generator, offering extra protection against bacteria, viruses, and VOCs.

A built-in PM2.5 air quality sensor allows for real-time tracking and automatic fan adjustment, while the digital display is clean and easy to read. Noise levels are low, rated quieter than a whisper at 22 dB in sleep mode. Its maximum rated power is 38 watts, which is decent for this capacity and function. Filters typically last 6–12 months depending on usage, and replacements are easy to source at around $69 each—the filter replacement indicator will also alert you when it’s time for a filter change.

If you want real-world HEPA-14 performance, UV safety, and large-room capability in one affordable package, the NNIO NH14PRO ticks all those boxes—sans any hype or unnecessary fluff. I’m tempted to get one!

The NNIO HEPA-14 air purifier (NH14PRO) is on sale at $228 from NNIO, Lazada and FairPrice.

Levoit Core 400S Smart Air Purifier, $339

Best quiet smart air purifier for small homes and allergy relief

The Levoit Core 400S is one of those highly-rated, award-winning models that gets recommended over and over again in user reviews—which says a lot, right? It is particularly touted for its quiet operation and allergy-helpful filtration.

It uses a 3-stage filtration system, with a H13 True HEPA filter, an activated carbon layer, and a fine pre-filter—together trapping 99.97% of airborne particles down to 0.3 microns, including pollen, dust, pet dander, second-hand smoke, pesticides, VOCs, and mould. What’s great is that it also handles odours really well.

This is a smart one, which syncs with the VeSync app and works with Google and Alexa. Easily monitor your PM2.5 levels in real-time and schedule operation remotely or using voice control. I find these smart functions genuinely useful without feeling gimmicky. Auto Mode adjusts fan speed based on pollution levels, and Sleep Mode is so quiet (~24 dB) that you probably won’t even notice it running at night.

It’s also Energy Star certified, using around 38 watts on high and significantly less on low—not bad at all for 400 sqft coverage (roughly 37m²). Filter replacements are affordable (~$55) and easy to source. On balance, a very good bet if you’re shopping for a quiet and smart air purifier for a studio, one-bedroom apartment or two-room HDB flat.

The Levoit Core 400S is priced at $339 on Shopee and Lazada

Novita Dehumidifier + Air Purifier The 2-In-1 ND26+, $598

Best multifunction air purifier for humid homes in Singapore

Now, for that 2-in-1 I promised. If you live in Singapore, you’ve probably most definitely heard of Novita—and the ND26+ is their new dehumidifier-cum-air-purifier offering. This one’s for people who want more than just HEPA filtration. If you live in a humid space (and in Singapore, who doesn’t?), this 2-in-1 system hits that perfect intersection between keeping the air clean and keeping the walls, laundry and closets dry and mould-resistant.

Firstly, air purification. It offers two filter options: an H13 HEPA filter & Hi-Performance CarbonPlus filter (or the Hi-Performance CarbonPlus filter alone) to remove up to 99.97% of airborne allergens 0.3 microns in diameter including fine dust, haze, smoke, pet dander, mould spores, pollen, some bacteria and viruses, odours, airborne chemicals and VOCs. It also has an ioniser function, which further neutralises any lingering germs and allergens in the air—should you choose to turn it on.

But where this unit really shines is its ability to dehumidify. It can extract up to 26 litres of moisture per day covering up to 650 sqft, and there’s a built-in laundry drying mode as well—which is very useful for drying clothes indoors (during monsoon season perhaps). It even comes with a Smart Humidity Sensor that lets you set your ideal RH (relative humidity) levels between 30% and 80% for healthier air (40-50% RH being ideal).

There’s also an UV-C LED sterilisation to boot, with 99.99% elimination efficiency for nuking those pesky microorganisms such as bacteria, viruses, cysts and mould. This sounds like an amazing mould-killing machine, which is something I could really use in the endless battle against mould in our extreme Singaporean humidity.

The dehumidifier tank is 5 litres, which is decent, but you can also attach a hose for more hassle-free and continuous drainage. It’s not the quietest unit on the market (running at around 42 dB in sleep mode), but that’s to be expected from a combined dehumidifier and purifier.

“Designed with energy efficiency in mind, ND26+ consumes only 245 watts at 27°C/RH60%”, which is something to consider if you plan to run it all day. That said, what you don’t save on energy, you can at least save on space—a 2-in-1 means you don’t need two bulky machines, just one!

The Novita ND26+ is on sale at $598 from Novita, Lazada and Shopee. Comes with a ten-year warranty for consumer peace of mind.

Air purifiers vs Dehumidifiers

Commonly confused, the air purifier and dehumidifier—while both improving indoor air quality—serve very different functions. An air purifier uses HEPA and activated carbon filters (or particle filters) to trap airborne particles such as dust, pollen, pet dander, smoke, and harmful gases like formaldehyde and VOCs, hence “purifying” the air we breathe.

By contrast, a dehumidifier extracts moisture out of the air, which helps prevent mould growth, damp smells, and dust mite proliferation—all of which thrive in Singapore’s extremely humid climate. If you suffer from allergies or respiratory issues, an air purifier is the more direct solution, but if you’re battling mould, musty odours or condensation on windows and walls, a dehumidifier is what you need. In many households, though, using both an air purifier and dehumidifier in tandem can create a healthier and more comfortable environment.

Some brands even offer air purifier and dehumidifier 2-in-1s, though many believe their performance pales in comparison to dedicated units—but that calls for another article. We will look specifically at dedicated air purifiers today, discussing what you should look for when shopping for one, before revealing the 10 best air purifiers in Singapore according to Singaporeans. But since we’ve touched on multifunctional air purifiers, I’ll make sure to throw in one that dehumidifies as well into the list.

How to choose an air purifier?

Clean Air Delivery Rate (CADR): Simply put, this is the measure of how much air an air purifier cleans in a given period, usually calculated in cubic feet per minute (CFM). A higher CADR means a more powerful air purifier, which is necessary for purifying the air in a larger room.

Room Size & Coverage: Size absolutely matters when it comes to choosing an air purifier—not only the size of the air purifier, but the size of your home or room specifically. According to AHAM, you should always follow the 2/3 rule when choosing the right purifier for your room—the CADR of your air purifier should be at least two-thirds of the room’s area. Matching the air purifier to your room size will ensure the model is effective for the square footage of your room, E.g., your living room would typically need a higher CADR air purifier than your bedroom.

Filtration efficiency: The current gold standard is a “True HEPA filter” where HEPA stands for “High Efficiency Particulate Air”. While both are considered medical grade filters, the HEPA H13 filters at least 99.95% of particles as small as 0.3 microns in diameter, while the HEPA H14 achieves more than 99.995%. At a residential usage level, the difference between the two seems negligible and a HEPA H13 is probably good enough unless someone in the home is particularly sensitive or at risk.

Additional filters: Often used in addition to HEPA filters, activated carbon filters absorb gasses, odours and VOCs using charcoal, while UV filters kill bacteria and viruses using ultraviolet light. Some air purifier models include pre-filters made of fiberglass or pleated materials to trap larger particles (like dust and pet dander) and extend filter lifespan.

Filter replacement: This is important when considering ongoing costs and convenience. Check your air purifier model’s filter replacement cost and availability, and choose brands with easily sourced and affordable filters to prevent future headaches.

Energy efficiency: If you’re planning to run it 24/7, look for low wattage consumption air purifiers, ideally with Energy Star certification if available.

Noise level: Generally speaking, you would want to look for a model that operates at under 30 decibels in sleep mode so your air purifier stays near-silent at night. For some mummies like me, however—whose young children sleep better with white noise in the background—the air purifier serves double duty both as air purifier and white noise maker.

Key functions: Some typical functions you’d expect of an air purifier include auto mode, sleep mode, air quality monitoring, child lock, app/smart controls, etc. Take note of the functions an air purifier offers, and decide which ones you really need or can live without.

Special features: Some air purifiers come with an air quality light indicator which informs you of the room’s air quality at just a glance. While useful, this is not something everyone wants to see—I personally prefer that my air purifier goes pitch dark at night. Another trendy feature of late is the negative ion function where air purifiers use high voltage to create negatively charged particles that help remove airborne pollutants. Some believe negative ions offer certain health benefits including mood improvement and better sleep quality, but I have shunned them because these ionisers emit ozone as a by-product—which is directly harmful for respiratory health!
