12 Best Air Purifiers in Malaysia 2024 (For Home & Office)

Breathing clean air is a basic human right

Did you know that even indoor air is full of germs, allergens, smoke, and other airborne contaminants? Just because it's invisible to the naked eye doesn't mean it's not a threat.

The air is not as clean as you think

I like to remind my vape-user colleagues about the air they breathe in with our air quality monitor.

Sterra, a trending air purifier brand shared that many Malaysians are not aware that everyday activities, like cooking, can significantly impact indoor air quality. Frying food, for example, releases fine particles and gasses that can be harmful when inhaled. This is why air purifiers are highly recommended in Malaysia.

Air purifiers work if placed correctly

It's nice to consider an air purifier for its looks if you're particular. For example, our room is a mess but, our Dyson air purifier still blends in well.

Moreover, Malaysia's tropical climate can greatly enable indoor air quality issues. With our weather's high humidity, it can easily promote the growth of mould and mildew.

Both release spores and mycotoxins into the air, thus impacting health in the long run. That's why it's important to use air purifiers correctly.

Samsung Malaysia says that it's ideal to have your air purifier at a minimum of 18 inches away from the wall or any furniture. If you can, place it best near the midpoint of your room.

Are air purifiers useful for dust, allergies and odour?

An air purifier works to filter the impurities in the air via a filtration system that traps small and large airborne particles and also helps to eliminate odour in the room. Even if you have no allergies, air purifiers are useful for everyone as they can also trap typical dust in the air which can cause flu-causing allergens.

You might also want to know that a bigger air purifier with a bigger filter is able to capture more dust and also clean in bigger spaces. At least, that's what Coway Malaysia said about their top air purifiers such as the Storm 2.

A cleaning tip we love: Use a crevice nozzle attachment head to quickly vacuum the dust off your air purifier's filter!

Struggle to get a Coway or Cuckoo air purifier? Don't worry, there's also a plethora of options in the market, such as Blueair, Levoit, and Philips. While top air purifier brands can be quite expensive for the average household to clean something invisible, it's still okay to try cheaper or smaller air purifiers. Just know that they might not be as effective in the long run.

We understand that you might be overwhelmed. With that, you may want to consider some air purifier options below, some known as the best air purifiers in Malaysia. 


List of 12 Best Air Purifiers in Malaysia

add_circle Utilise various bacteria and virus-killing methods including UV
add_circle Energy-efficient
add_circle Strong airflow to ensure your space is properly covered

Who is this for?

The Sterra Breeze Air Purifier is nearly 100% efficient against particles with a diameter larger than 2.5 μm, which is what hospitals use in their rooms to help decontaminate and clean the air. Not only that, but because it can run as silently as 20dB (a library noise level is 40db), the Sterra Breeze Air Purifier is made to be used in sizeable bedrooms and living rooms as well. 

Get this if

  • You are constantly sick (from viruses)
  • You want a proven method that kills harmful bacteria besides air-filtration

What to know

Designed with a medical-grade True HEPA-13 filter; this air purifier utilises its TotalCleanse Filter System™ to clean up to 99.95% of airborne particles and cover spaces of up to 80m with about a strong 400m3/h airflow so that your space is properly protected. 

Aside from its sterilisation feature, the purifier also releases healthy ions that aid in binding viruses, dust particles, free radicals, and pollen in the air; essentially clearing particles that are harmful to allergy sufferers. Alongside those, the purifier can also clear formaldehyde which is a toxic gas released by gas stoves.

While you can choose to opt it out, we highly recommend getting the purifier with UV Tech which employs a UV-C light to trap and destroy bacteria as well as viruses in the air. 

Those who are big on saving electricity would really appreciate the UV upgrade as it’ll consume about 40% less energy, taking 52.2% less footprint compared to other similar products in the market.

  • CADR: 400 m³/h

About our top pick

While most air purifiers already do a good job of filtering out the bad, the Sterra Breeze's UV tech and sterilisation capabilities make it a unique winner in our books. For your information, this air purifier uses the natural way of killing viruses and bacteria rather than just using a medical-grade HEPA filter, which extends its efficiency. Essentially, if you are wary of viruses, Sterra Breeze would be a good option.

Did you know the smoke that comes from cooking is called Formaldehyde? It is a highly toxic and flammable gas emission, hence why condominiums or smaller houses should install kitchen hoods. But not everyone needs to buy a kitchen hood for that matter. Therefore, if you want to be able to control the amount of this emission, try an air purifier that can help you with it.

Although the cooling power is not as big as regular fans, it is still a useful feature given how hot Malaysia is. Of course, most existing users have purchased it for its ability to destroy formaldehyde.

Behind its filtration power lies its HEPA H13 filter which can remove 99.95% of particles as tiny as 0.1 microns. Not only that, but the air purifier is able to double as a bladeless fan thanks to its powerful stream of purified airflow. Best of all, it’s 20% quieter than the previous model thanks to acoustic engineering that reduces turbulence.

Check Panasonic Portable Air Purifier NANOE X Generator price below:
add_circle Restores moisture in the air to the skin and hair
add_circle Very portable; can easily fit in car cup holders
add_circle Low power consumption

Who is this for?

Due to its size, this air purifier is best used in an enclosed, small space rather than being all out in the open in order to reap benefits from it. That is why this air purifier is a worthy buy for car owners be it travelling far often or for families with kids who are concerned about their health. Aside from those, it can also clean surrounding moisture from developing harmful microorganisms.

Get this if

  • You (and your passengers) want a car to feel as clean and comfortable as possible

What to know

Panasonic's Portable Air Purifier NANOE X Generator is made to get rid of as many as 99.99% harmful microorganisms as possible. It essentially utilises nanoe™X technology which releases radicals in water molecules to viruses, bacteria, odours and allergens.

Aside from cleaning your air, the air purifier can remove smells too. Take, for example; it's designed to reduce strong cigarette smoke odour within an hour.

Moreover, you can refresh in your car as this purifier generates nanoe™X particles, which have an acidity nature that's similar to the human skin and hair. In short, the particles will attach to sebum and form membranes on the skin all the while improving the hair's keratin texture. Moisture is then restored to your surrounding area, bringing you well-hydrated skin and smoother hair.

  • CADR: 0.07m³/min

Alright, if you're here to find out whether air purifiers target killing allergens, be it pet dander or so, in the air because you're sensitive, most air purifiers can do the job well. We think HEPA filters are best since they are usually hospital-grade (a place prone to lots of harmful allergens and viruses in the air). Air purifiers that also have some Auto Mode functionality or more customisation and monitoring features should be a priority for those with respiratory issues.

FAQ:

How To Choose the Right Type of Air Purifier?

Air purifiers are those 'mysterious' products where results aren't visible but can be felt after a while. To easily pick the best for yourself, you can look to pick one based on the filter it uses:

High-Efficiency Particulate Air (HEPA) Filters

The most popular out of the bunch, HEPA filters, are treated as a "necessary" type of filter as they can remove up to 99.97% of airborne particles that are 0.3 microns or larger. True to their name, they are highly effective in removing pollutants like dust, pollen, and pet dander from the air. However, they do not do much when it comes to removing gases and odours.

Pros:

  • Great for removing allergens and particles
  • Recommended for improving air quality when it comes to asthma or allergies issues
  • Comes in most air purifiers; easy to find

Cons:

  • Does not remove pollutants such as gases and odours
  • HEPA purifiers can be noisy and may require frequent filter replacements.

Activated carbon filters

Designed to remove odours, these filters aim to clear volatile organic compounds (VOCs) and other gaseous pollutants from the air. They basically absorb said pollutants and trap them onto the surface of the activated carbon.

Pros:

  • Works to remove odours and gaseous pollutants
  • Recommended for improving air quality if you have chemical sensitivities

Cons:

  • May require frequent filter replacements if exposed to high levels of pollutants

UV-C Light Air Purifiers

By utilising ultraviolet light, air purifiers with this filter can kill bacteria and viruses that may be present in the air. These purifiers typically work in conjunction with HEPA filters or activated carbon filters.

Pros:

  • Effective at killing bacteria and viruses, ultimately lowering chances of one catching a flu or cold
  • Best for those with respiratory illnesses

Cons:

  • UV-C light can be harmful to humans and animals if exposed directly
  • Expensive initial cost

Ionic Air Purifiers

A relatively rare filter type, these purifiers use charged plates to attract and remove particles from the air. They are designed to create negative ions, then attach to particles in the air and then deposit (or trap) them onto a positively charged plate.

Pros:

  • Silent operation
  • No filters to replace
  • Good quality ones can remove some types of pollutants like dust and allergens

Cons:

  • Less effective at removing gaseous pollutants and odours
  • May produce ozone, which can be harmful to human health in high concentrations
  • It might not be effective at removing smaller particles and may even generate additional pollutants if not cleaned regularly

- What are hospital-grade air purifiers?

You might have come across the label "hospital-grade" for air purifiers. While we put our trust into such a term due to the fact that it's automatically regarded as safe by professionals, that doesn't mean you should limit yourselves to these variants only.

It's just that these air purifiers have been tested to meet a certain standard quality and are therefore considered extra precaution and assurance for customers.

Here's what Sterra shared about 'hospital-grade' air purifiers:

  • Hospital-grade air purifiers are those that meet certain stringent standards for air purification. These purifiers must be able to remove a high percentage of particles from the air, including those as small as 0.3 microns, such as bacteria and virus particles.
  • Sterra air purifiers, classified as hospital-grade, are therefore deemed effective at removing these minute harmful particles from the air.

- Differences between HEPA air purifiers & Ionic air purifiers

While both HEPA air purifiers and ionic air purifiers serve the same purpose, they work rather differently.

The science behind air purifier filters

HEPA air purifiers use HEPA filters, which are physical filters that trap airborne particles. The air will be drawn into the device, then go through the filters, and finally, come out clean and contaminant-free.

An ionic air purifier, on the other hand, works by emitting negatively charged ions into the air to bind with the particles, which are positively charged. As they bind together, the particles will become too heavy to stay in the air and thus, fall onto the surfaces around them, producing clean air.

Some ionic air purifiers use electrostatically charged plates instead of ion emission to collect the airborne particles. As the air is drawn into the device, the particles will stick to the plates, which results in clean air.

Effectiveness of air purifiers

HEPA filters are known as the best technology in the air-filtration industry. They are highly effective “collectors” that can remove up to 99.97% of impurities in the air. 

Ionic air purifiers are less effective than HEPA air purifiers as when the electrostatically charged plates become dirty, the harmful particles can pass through the plates and remain in the air — which doesn’t happen to HEPA filters. Also, ionic air purifiers that work by ion emission technically do not remove the airborne particles but rather just “move” the particles to the surrounding surfaces such as the floor, furniture, and even on clothes.

Maintenance of air purifiers and filters

HEPA filters need to be replaced from time to time as dust and mould collected through the filtering process degrade their air-cleaning performance while ionic plates do not. Instead, ionic plates are to be washed regularly.

Which filter-type is the best?

HEPA air purifiers are usually preferred over ionic air purifiers, especially for people who suffer from asthma and allergies.

Additionally, many air purifiers available on the market these days are a hybrid of both mechanisms: they are built with a HEPA filter and an ion generator. This combo delivers even better effectiveness and performance.


- Benefits of an air purifier 

Of all the charms we have heard about an air purifier, we bet that most of you are familiar with its ability to produce cleaner air by filtering and trapping dust, smoke, pet fur, mould, dust mites, and germs from your surroundings. But an air purifier does more than just that. It benefits you in other ways that you may not even be aware of until today. 

Improves sleep quality

Acknowledged by the fact that hazardous air particles are being removed from your home, air purifiers save you peace of mind and calm you down after a long day. The fresh filtered air keeps hay fever (which causes allergic symptoms like runny nose, sneezing or coughing) at bay, granting you a good night’s sleep.

Neutralises unpleasant odours and smoke 

It is commonly known that inhaling secondhand smoke, be it tobacco smoke or cooking oil fume, can potentially lead to chronic respiratory problems as well as heart diseases. This is especially concerning if you have children or elderly people at home. 

That said, air purifiers with High-efficiency Particulate Air (HEPA) and activated carbon filters are effective in capturing chemicals, gases, smoke and also pet odour to circulate fresh air back in the room.

Eliminates hazardous indoor air pollutants 

The tricky part when it comes to eliminating indoor allergens is that they are invisible to the human eye. These tiny airborne particles (dust, pollen, bacteria, etc.) or harmful external pollutants do not go away just by closing the doors and windows. You could constantly be exposed to the chemical toxins from your household cleaning agents, air-fresheners and paint products. 

Leaving these pollutants suspended in the air is likely to cause breathing discomfort and trigger asthma attacks, not to mention the associated health issues in long term.

- How do air purifiers work? 

Air purifiers consist of a fan and layers of filters. The built-in fan draws in air and directs it to the filters to get rid of the contaminants. The clean air is then released back into the room to maintain healthy indoor ventilation. 

The marketed air purifiers are commonly equipped with HEPA filters which claim to capture pollutants as small as 0.3 microns – small enough to get past the tiny hairs (cilia) in our airway. However, there are other types of filters such as activated carbon, UV light, negative ion or ozone generators to suit your personal needs. 

An average person takes 1,200 breaths an hour, 28,800 breaths a day and 10,512,000 breaths a year. Bearing in mind that you would not even drink unfiltered and dirty water, so why would you allow yourself and your loved ones to inhale stale and dirty air at home?


Conclusion

With all of that in mind, investing in an air purifier is ideal for a comfortable, refreshing ambience and your family’s health overall. Not only that, but clean air does make your living space much more comfortable to stay at, which keeps the mind and soul healthy too. Especially if you are prone to allergies, best to treat your nose with these nifty devices!
