As regular sufferers will know, allergy season isn’t much fun. Same goes for climate change, which is contributing to these ever-worsening pollen seasons. Among the culprits are high temperatures and raised levels of carbon dioxide, both of which can affect the proteins in the pollen grains — the very things that cause these allergies.
What you need is an air purifier. But not only to combat allergies. Indeed, there are all kinds of nasties floating around — dust, pollen, smog, mould spores, and pet dander.
Eliminating these airborne particles is one way to cope with allergies and other respiratory issues — and there's no better way to trap these pain-in-the-backside irritants than by using an air purifier with a HEPA filter. But how to choose the right one? It can be confusing, but fear not, because we can help clear the air.
What is an air purifier?
True to its name, an air purifier sucks in dirty air, purifies it, and releases the clean air back into the atmosphere. The air is put through a filter — or multiple filters in some models — which helps remove all kinds of pollutants and particles.
What is a HEPA filter?
You’ll see this acronym a lot when shopping for air purifiers. It means High-Efficiency Particulate Air filter. HEPA filters use thousands of very fine fibres to catch particles of all sizes. In short, it’s the industry standard and will remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles down to a size of 0.3 microns (in other words, very small). Some air purifiers also use carbon activated filters, which trap molecules and particles through a process called adsorption.
What do air purifiers filter out of the air?
A good air purifier will catch around 99.97% of unwanted nasties from the air. This will include dust, allergens, pollen, mould spores, pet dander, volatile organic compounds (VOCs), viruses, bacteria and lingering odours. Indeed, air purifiers are ace when it comes to ridding a space of animal smells like litter boxes and pet beds, as well as clearing the air of smoke stench from cigarettes or fires — and all without needing to open a window.
What features do air purifiers offer?
It all depends on how much you’re willing to spend. You’ll find air purifiers that are relatively cheap but have no extra features. But if you’re willing to fork out a bit more — and, hey, you can’t put a price on healthy air — top-of-the-range models have all kind of features. These might include app connectivity, voice command, sleep mode, timers, and sensors that detect the air quality and adjust performance accordingly.
What is the best air purifier?
That’s ultimately up to you and may depend on numerous factors, such as the size of your home and lifestyle. But we’re not just blowing hot air here. We’ve tracked down some of the best air purifiers on the market for you to consider. Whether you need something small to take from place to place, or if you're in the market for an air purifier that can handle the whole house, you're totally covered.
These are the best air purifiers in 2025.
Philips Series 3000i
Best For Style
The Good & The Bad
- Good design
- 360-degree circulation
- Automatic features
- App and voice control
- Not exactly cheap
Why We Like It
The Philips Series 3000i reduces allergens, odours, viruses, and bacteria, thanks to a combined HEPA and carbon filter. The all-around design provides 360 degrees of airflow, which makes it perfect for medium to large rooms.
What sets this device apart from the competition is that it automatically monitors and purifies the air in your home, and the results can be tracked on the Air Matters app, which provides real-time air quality feedback. Other nice touches include a sleep mode — which provides ultra-quirt action — and Alexa compatibility for voice control.
There’s no denying this purifier is on the expensive side, but not many competing models match this for features.

Levoit LV-H132
Best For Desktops
The Good & The Bad
- Good size
- Relatively powerful
- Sleek cylinder design
- 3 fan speeds
- 3-stage filtration
- On the louder side
Why We Like It
For smaller rooms or offices, you might not need a massive cleaner that sits on the floor — but that doesn't mean a mini one is your only other option.
The Levoit LV-H132 air purifier is one of the sleekest little guys on the market, and though it's small enough to sit on a desk, its cleaning capacity is massive.
There are three fan speeds to choose from, while a three-stage filtration system kills 99.7% of dust, pollen, and pet dander. It's also 100% ozone free — this basically means that it does not use UV or ions, which produce trace amounts of measurable ozone.

Dyson Pure Hot+Cool
Best For Features
The Good & The Bad
- Multi-function
- Bladeless design
- Pretty much silent
- Alexa and app enabled
- Advanced tech
- Expensive
Why We Like It
The Dyson Pure Hot+Cool is truly ahead of its time. It uses bladeless Air Multiplier tech, which pulls in dirty air, puts it through multiple diffusers and filters, and then circulates pollutant-free air through the room. The hollow design is testament to its performance — it's one of the simplest devices to use on this list.
A mini LCD screen on the front shows you the current status of your air, and the Dyson app gives detailed info on the quality of the air outside and the type of pollutants most affecting your home. If the app senses that polluted air increases in your home at a certain time of day, you can set timed cleaning schedules.
The effortless peace of mind is enough justification on its own, but the cooling fan and heater addition allows you to control the temperature all year round.

WINIX ZERO Pro
Best For Large Rooms
The Good & The Bad
- SmartSensors
- PlasmaWave tech
- Large coverage area
- 4-stage filtration
- Sleep and auto modes
- Awkwardly large
Why We Like It
The Winix U450 air purifier is packed full of advanced features, but it's the coverage area of this device that makes a big impression — a whopping 120 square metres. That means it can handle large bedrooms, family rooms, kitchens, and even offices.
It might be a bit on the bulky side, but that’s because it’s packing plenty of technology. There’s a four-stage filtration system — taking care of odours, smoke, pet dander, bacteria, viruses, pollutants, and allergens — plus PlasmaWave technology, which creates Hydroxyls to neutralise bacteria and viruses.
Another impressive feature is the SmartSensor that automatically gauges the room's air quality and adjusts the strength of filtration. The sleep mode also provides you with a quiet and clean environment at night. It has an eight-hour timer, too.

PureMate With UV Lamp
Best For Tight Spaces
The Good & The Bad
- Optional UV lamp
- Ioniser feature
- Slim design
- 5-stage filtration
- Can get loud
Why We Like It
The name PureMate may seem corny, but this device really could be your best friend.
The HEPA filter captures 99.97% of allergens like household dust, pet dander, mold spores, and plant pollens — as small as 0.3 microns. For rooms that need a heavy-duty cleaning, it has sanitising UV light technology. The UV lamp works with Titanium Dioxide and an optional ioniser and takes care of airborne nasties.
Not only does it clean the air by trapping particles you can't even see, it makes things smell better, too. And though it sits on the floor, it's not cumbersome. It's slim enough to be tucked in a corner, in between furniture, or somewhere else out of the way.

Silentnight Air Filter
Best For Pets
The Good & The Bad
- 3 speed settings
- Ioniser feature
- Timer function
- No coverage area listed
Why We Like It
Silentnight is all about making sure you get a good night's sleep, and the Silentnight Air Purifier does just that. You can literally rest easy.
This triple filtered air purifier is capable of removing 99% of all airborne contaminants from the air including pollen, mould spores, dander, and odours. If you have a pet, or you smoke, this is an ideal option. It can also be set to run on a timer and has a sleep function that cuts out during the night once you are settled.
The three-stage filter starts with a sponge layer that removes the larger particles, a HEPA filter that removes air smaller particles, and the final carbon filter that removes the last very fine particles that tend to carry those lingering smells.
