While we generally enjoy good air quality in Singapore, there are times when the island is covered with smoke. During the annual haze season in Singapore, it’s always good to have an air purifier to help us filter those harmful PM2.5 particulates.

But before we get to our list of the best air purifiers in Singapore, let’s find out more about how the various types of air purifiers work.

Types of air purifiers

1. Ultraviolet air purifiers

Ultraviolet (UV) air purifiers work by zapping viruses, bacteria, and pathogens with UV rays. These rays break up molecular bonds in their DNA and prevent the cell from dividing, which stops infection entirely.

Residential UV air purifiers are small and compact, and the light rays are contained within a chamber.

Because UV lights run on a bulb, you’ll have to replace the bulb once it wears out. How often it wears out depends on your frequency of use and the model of bulb, but a good gauge would be once a year.

These air purifiers are suitable for killing moulds, viruses, and bacteria, although they are pretty useless when it comes to stuff like fur and dust. To cover for this weakness, most UV air purifiers work in tandem with other filters, which will be covered below.

2. HEPA air purifiers

HEPA is an acronym for High-Efficiency Particulate Air. Air purifiers that use HEPA filters can trap an estimated 99.97% of all particles larger than 0.3 microns.

Here’s a bit more information on what a micron is:

  • A micron is a term used to describe a millionth of a metre, or 1/1000 of a millimetre.
  • The smallest particle that can be seen with the naked eye is anything above 50 microns.
  • A human hair is about 100 to 150 microns across.
  • Bacteria range from 0.2 microns to 3 microns.

HEPA filters work by trapping particles in one of these 3 ways:


Particles that come within the radius of a fibre is stuck to it due to static.


Particles that collide with the fibres are embedded in them and trapped.


Particles that collide with gas molecules are slowed, making it more likely that they get stuck to a fibre.

While HEPA filters may be the most effective way to trap airborne particles, they fall flat when it comes to removing odours, chemicals, or gases. That’s why most HEPA air purifiers often come with some sort of activated carbon filter to absorb whatever passes through the HEPA filter.

HEPA filters also have to be replaced every 2 to 4 years, once the filter becomes overly saturated. Air purifiers in Singapore that utilise this technology will probably need to have the filters changed after each haze season.

3. Activated carbon technology

Activated carbon filters are made from processed carbon, which makes it extremely porous. This gives it a very large surface area and makes it perfect for absorbing all those nasty toxins out of the air.

The activated carbon can effectively absorb pollutants such as chemical emissions, gases, tobacco smoke, and other odours. Any captured pollutants will not be released back into the air, eliminating the risk of recontamination.

These filters also work well in absorbing formaldehyde, which can be found in certain types of household furniture. Perfumes and other fumes are also absorbed by the carbon filter, making it easier for those with asthma and/or sensitive noses.

Unfortunately, they don’t perform that well when it comes to removing airborne particles and allergens, since it relies on absorption rather than sticking. For instance, you can throw a strand of hair into a HEPA air purifier and it would disappear. But if you repeated the same action with an activated carbon purifier, your strand of hair would simply fall to the ground.

They also work poorly around contaminants that are too far away, since they rely quite heavily on a fan to force air through the filter.

4. Negative ion/ ionisers

Negative ion air purifiers fire out negative ions into the air. These negative ions are simply oxygen molecules that have been given an electron. Negative ions attach themselves to smaller particles such as pollen or dust. They will form into a bigger one for easier filtration by the air purifier.

But these particles may also not get filtered by the air purifier. Instead, they attach themselves to a solid surface, such as a wall or a curtain.

5. Ozone purifier

Ozone air purifiers work in a similar manner to negative ion purifiers, but make use of ozone to trap pollutants instead. When it makes contact with organic material, it reacts with the item while creating oxygen as a byproduct. This makes ozone very effective at getting rid of odours, mould, and microbes.

However, ozone can irritate the lungs over time. Another thing to note about ozone is that it doesn’t remove stuff like dust and pollen, so they have to work in tandem with negative ion technology – which also doesn’t remove stuff like dust and pollen.

Here is a handy list of what each air purifier can do, assuming it doesn’t come with multiple filters.

Type of air purifierCapability
HEPATraps airborne particles, bacteria, and virus that are larger than 0.3
Activated carbonAbsorbs odours
UVKills bacteria and virus
IoniserProduces negative ions that stick to airborne particles, bacteria, and
virus to get rid of them
OzoneProduces ozone molecules that
react with odours, moulds, and
microbes to get rid of them

With that, let’s get on with our list of the best air purifiers to get in Singapore, which can come in handy especially during the haze season.

Ionisers are useful when paired with a fan to ‘sweep up’ the affected particles, and potentially create a positive vibe in your home.

We didn’t include any UV air purifiers because they’re not really air purifiers as much as they are virus sterilisers, and ozone purifiers are detrimental to your health.
