Different Kinds of Air Purifiers You Wish to Know Prior to Purchasing in Australia

The market is full of a wide range of air cleaning devices with different filtration technologies. The sheer number of options can be overwhelming, making it hard to choose the right one for your needs.

One of the best devices that gives the best result is an air purifier. With this device, you can have peace of mind knowing that the quality of air inside your home is clean and safe for everyone. The quality of air that we breathe in has a direct impact on our health. According to the World Health Organization (WHO), poor air quality is linked to over 7 million deaths each year.

When it comes to purchasing an air purifier, many people often think that they only need to choose between two general types – portable or whole-house units. However, there are actually different kinds of air cleaners available in the market, each with its own set of benefits and features.

However, with the many different models, designs and features, you should know the available options before making your purchase. Here are some of the most common types that you can pay attention to:

1. Electrostatic Precipitators

Electrostatic precipitators help purify the air by using electrostatic force to capture and hold dust and other particles. It is one of the most effective ways to remove particles like dust, pollen and smoke from the air. 

These units are designed to work for 24 hours straight while consuming minimal power, and they effectively contain oil, grease and smoke in a kitchen exhaust system.

If you’re suffering from airborne allergies, this type of air purifier can be a great choice for you.

2. High-Efficiency Particulate Air (HEPA) Filters

One of the most common types of air purifiers is the HEPA filter. It uses a mechanical process to remove particles from the air. A true HEPA filter must be able to remove at least 99.97% of particles that are 0.3 microns in diameter. This is best for people who suffer from asthma or other respiratory conditions.

Moreover, a HEPA filter destroys 99.9 per cent of aerosolized viral particles in the air. Respiratory droplets range in size from roughly 300 nanometers to more than 100 micrometers, with a diameter of approximately one millimeter.

3. Activated Carbon Filters

Strong odour and harmful gases inside your home can have a negative impact on your health. Activated carbon filters are designed to remove these airborne contaminants. This type of air purifier is especially effective in removing smoke, chemicals and other VOCs (volatile organic compounds).

4. Photocatalytic Oxidation (PCO) Filters

PCO is an innovative air purification method that eliminates pollutants rather than blocking them, thanks to a particular chemical reaction. This reaction transforms pollutants into harmless substances such as carbon dioxide (CO2) and water.

PCO filters are a newer technology that uses ultraviolet light to break down contaminants. It is effective in reducing VOCs, mould, bacteria and viruses. This type of air purifier is often used in commercial and industrial settings. 

The photocatalytic oxidation air purification technique typically entails utilising an existing air system that draws air through an air conditioning unit (HVAC), which is then passed through the professionally installed ultraviolet light/titanium dioxide chambers. When the air filled with harmful contaminants circulates through these chambers, the microbes are destroyed by hydroxyl radicals and titanium dioxide.

Another key feature is that the filter does not require replacement because there are no pollutants or materials to replace. Therefore, the filter is permanent and does not need maintenance or additional supplies. This means that the element which causes the chemical reaction on the filter is not used up, making the coating more durable and long-lasting. This saves you money in the long run while also being environmentally friendly.

5. Ionisers

Ionisers produce negative ions, which attach to positively charged particles in the air and cause them to fall to the ground. This type of air purifier is effective in reducing pollen, dust and other allergens.

An ioniser is a device that uses electrical current to charge particles in the air, making them attracted to surfaces or each other. This process can be used to remove contaminants from the air, which makes it a popular choice for people who suffer from allergies or asthma.

If you want to do a better job of cleaning the air in your home, using an ioniser in conjunction with other purifiers, like HEPA filters, can give you more comprehensive protection.

6. Ozone Generators

Ozone generators are devices that produce ozone, a gas that is made up of three oxygen atoms. This gas is effective in reducing bacteria, mould and other contaminants.

Ozone generators are a type of air purifier that uses electrical current to charge particles in the air and create ozone. Ozone is a gas that is made up of three oxygen atoms, and it is effective in reducing bacteria, mould and other contaminants.

Ozone generators are often used in commercial and industrial settings, but they can also be used in homes. If you are using this type of air purifier in Australia, make sure that it is properly ventilated so that the ozone does not build up to unsafe levels.

7. Ultraviolet Germicidal Irradiation (UVGI)

UVGI in HVAC systems is an effective means of reducing or eliminating mould, bacteria and viruses, thereby lessening the occurrence of healthcare-associated infections. 

This air cleaning device uses UV lamps to produce radiation known as UV-C. The lamps are similar to fluorescent lights, and they usually have a ballast device or electronic units that help operate them. The amount of radiation applied to a particular volume of air is crucial for the devices’ effectiveness. The radiation dose rate is determined by a combination of light intensity and duration of exposure. It’s also been shown that certain microorganisms are more susceptible than others to UV radiation.

UVGI purifiers are frequently employed in businesses and industrial environments, but they can also be used in houses. It’s critical to ensure that your UV germicidal irradiation device is well-ventilated if you’re using it at home so the ozone doesn’t build up to dangerous levels.


Choosing the best air purifier for your needs will depend on a number of factors, including the size of the room, the type of contaminants you want to remove and your budget. It also requires time and effort to research the different types of purifiers and find the one that is best suited for your needs. But making the effort to do so will be worth it when you can finally enjoy clean, fresh air in your home.
