5 stage filtration with cleanable HEPA-type filter provides a high level of air filtration

The Pre-Filter helps to protect the HEPA-type filter by removing larger particles.

An Activated Carbon filter neutralises VOCs, harmful gases and odours from substances such as perfumes, hair spray, paints and pesticides reducing allergic reactions from the air that you breathe. 

The cleanable HEPA-type filter removes particles down to 2 microns such as dust, pollen, mould spores, dead skin and pet dander. It can be vacuumed when necessary.

The germicidal UV light is used for sterilising microorganisms such as germs, viruses, fungi and bacteria.

Finally the ioniser releases negative ions into outgoing filtered air to help the air purification process.

Ensure optimal performance and no hassle with a filter change indicator

To take the concern out of maintenance, the PM520 air purifier includes a filter change indicator to help you maintain optimal performance.

Take a look at our Filter Replacement Service tab for peace of mind.

Rest assured of its ability to clean air in your room sized up to 25m2

The PM520 air purifier will easily filter the air in your room size up to 25m2 3 times an hour when on the high setting.

The Healthy House® recommends their air purifiers based on a minimum of 3 air changes per hour.

Activated Carbon Filtration


What is Activated Carbon?

Activated carbon, also called activated charcoal, carbo activatus or an “AC filter”, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m2.


What Activated Carbon filters remove

Because of its super porous texture active carbon is able to attract, adsorb and neutralise smaller particles like organic gases, odours and some chemical compounds. These particles are too small to be trapped by other types of air purifier filters.


Activated carbon is a form of carbon that has been treated to make it extremely porous giving it a very large surface area available for the adsorption of chemical compounds. Activated carbon primarily adsorbs organic chemicals along with some larger molecular weight inorganic compounds. One gram of activated carbon has a surface area about one tenth the size of a football field.


If you would like to remove smells, gases or some chemicals from the air in your home an activated carbon filter is a very effective part of an efficient air purifier.

True HEPA Filtration

What True HEPA is

HEPA is short for for “High Efficiency Particulate Air” or “High Efficiency Particulate Arrestance.” True HEPA refers to a filter that is manufactured, tested, certified, and labelled in accordance with current True HEPA filter standards. The True HEPA filter must  capture 99.97% of the particles down to 0.3-micron particles in the air passing through it.

Efficiency is typically greater than 99.97% against larger or smaller particle sizes. Particles larger than 0.3 microns are more easily trapped, or intercepted, by the media. Smaller particles often lack sufficient mass to penetrate the media.

To meet the minimum requirements of a True HEPA filter, the filter must be tested and certified to prove that it will remove at least 99.97% (9,997 out of 10,000) of particles 0.3-micron in diameter from the air passing through the filter. Particles of that size are about 300 times smaller than the diameter of a human hair, and 25 to 50 times smaller than we can see. Manufacturing a filter with HEPA filter media does not mean that the filter itself meets True HEPA efficiency requirements.

What True HEPA removes

With filtration down to 0.3 microns and 99.97% efficiency the True HEPA filter will remove most dust, pollen, pet dander, mould spores, mites, cigarette smoke and even particles as small as bacteria and some viruses.

UV Bulb with Titanium Dioxide


What it is

UV light treatment is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UV light is used in a variety of applications, such as food, air, and water purification.


What it removes

UV light has ant-bacterial, antiviral, sterilising and deodorising properties against microorganisms.


Titanium dioxide

Titanium dioxide (TIO2) used together with UV bulb, decomposes odour molecules caused by smoking, cooking and pets.


Replacing the bulbs

UV bulbs will deteriorate over time and The Healthy House® recommends that they are replaced when they are not functioning,damaged, when no blue light is observed or at least every 12 months. Take a look at our Filter (bulb) Replacement Service tab for peace of mind.


Ionisation Information


What it is

Ionisation is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions. An air ioniser is a device that uses voltage to ionise air molecules. Airborne particles are positively charged and are attracted to the negative ions in a  similar way that static from your television attracts dust. The negative ions attach to these particles and form larger particles that can be trapped more easily by an air purifier filter or are attracted to surfaces within the room itself.


The ionisation process also has a disinfecting property on viruses and bacteria. This has a beneficial effect on bacteria and viruses trapped within the filter medium that may otherwise reproduce in that environment.


Ionisers are effective by themselves or, when combined with filters, can dramatically improve effectiveness of those filters.


What it removes

Ionisers will have a positive effect on particles such as dust, pollen, cigarette smoke and pet dander.
