For a Clean and Healthy Home

The Welcare PureAir range of Air Purifiers harnesses the latest in HEPA (H13) Filtration, UV Light and photocatalyst technology to provide clean, pure air. Perfect for those who have pets, suffer from allergies, bushfire or pollution prone areas, or simply whoever is looking to achieve a clean and healthy home or office environment.

The Victorian Government has announced a Ventilation Grant and Rebate for Small to Medium Businesses.

Included in the activities that qualify businesses for both the $500 Rebate and the up to $5,000 Grant is the purchase of Air Purifiers with HEPA Filters.

$500 Rebate – Spend at least $500 and receive the full $500 Rebate.

$1,000 – $5000 Grant – Apply for the grant and, if successful, the government will match your spending dollar for dollar from $1,000 up to $5,000. So if you purchase $10,000 worth of Air Purifiers the Victorian Government will pay $5,000 of that cost.

Key things to look out for in an Air Purifier

One of the key points to consider in the operation of an Air Purifier is the CADR rate. CADR is an acronym for Clean Air Delivery Rate. In general, this numerical value will indicate the quantity of particles to be removed from the air. Basically, a CADR rating indicates how fast the air purifier can clean the air within a particular size room by cubic metre per hour (cm/h). For example, an air purifier with CADR rating of 300 cm/h will clean a room of 300 square metres much faster than an air purifier with CADR rating of only 200 cm/h.

A CADR measurement is usually evaluated for pollen, smoke, and dust. These three pollutants are not only small in size but also the most unwanted particles in the air. Smoke particles are ultra-fine particles, with the defined particle size ranges from 0.1 to 0.3 microns. Dust particles are common particles with size from 0.5 to 3 microns. Pollen particles are the large particles which can usually be seen with the naked eye, with size from 5 to 11 microns.

Dust Sensor & Air Quality Indicator






Air filtration (filters) are also a critical element of air purifiers. Importantly, Welcare PureAir air purifiers use HEPA13 filters.

The HEPA13 filter is a medical-grade air filter which can remove all particles of 0.21 microns and larger with 99.95% efficiency. Common consumer air purifiers use H11 and H12 standard HEPA filters, which can trap 0.3-micron particles at 85% to 95% efficiency. Medical-grade filters, including HEPA 13 filters, are commonly used in airplane cabins, semiconductor fabrication plants, pharmaceutical plants, and hospitals. The reason why they are used in these environments is because they have a higher particulate capture rate.

Importantly, not all HEPA filters are the same. There are many types of air filters which are claimed to be of high-grade filtration – ‘True HEPA’, ‘HEPA-like’, ‘H13 HEPA’, and ‘Medical-Grade HEPA’. The question is – are all these the same kind of filter, or are there differences between them?

“(HEPA filters) remove at least 99.97% of airborne particles 0.3 microns (μm) in diameter. The filter’s minimal resistance to airflow, or pressure drop, is usually specified around 300 pascals (0.044 psi) at its nominal volumetric flow rate.” (DOE)

In short, HEPA filters capture small particles like dust, pollen, mold, smoke & pet dander (pet hair)

‘True HEPA’ is simply a marketing term which companies producing HEPA filters have developed over the last decade. There is no difference between an air purifier with True HEPA vs HEPA filters; it’s just that True HEPA was tested to sound better in consumers’ ears.

There are different classes of HEPA filters, according to the EN 779 normalisation standard. Classic HEPA filters are usually H10, H11, or H12 class. The best HEPA air purifiers will use H12 or higher rated HEPA filters.

Importantly, HEPA 13 (or H13) are even better than normal HEPA filters. Specifically, the H13 filter captures particles that are more than 3x smaller than classic HEPA filters.

HEPA 13 filters remove at least 99.9% of airborne particles 0.1 microns (μm) in diameter.

Accordingly, when compared to HEPA or True HEPA, HEPA13 filters remove even the smallest particles which True HEPA filters are unable to capture. This includes asbestos particles, paint pigments, insecticides, and so on.

HEPA 13 filters are so thorough they are used in clinics, hospitals, and dental offices.

What’s the difference between the H13 HEPA filters and Medical-Grade HEPA filters?

There is none. The bottom line is H13 HEPA filters are simply so thorough they are used in medical settings; hence the name ‘Medical-Grade’.

WPA300 Household Air Purifier:

Pre Filter

The Pre-Filter is washable and therefore will last a very long time. It is recommended to change the pre filter every 3 years, or if it is visibly damaged. (*subject to air quality and hours used)

HEPA (H13) filter & Carbon filter

These two filters are recommended to be replaced every 6-12 months or after 1600hrs of use. (*subject to air quality and hours used)

The time for filters to be replaced can differ due to the air quality and amount of hours the filter is in operation. Generally speaking, the air quality in Australia is good, however, the quality does differ in different parts of the country, you can check the HEPA filter by assessing the cleanliness, if it is looking discoloured, it is time to change it. We recommend to change the HEPA (H13) filter and Carbon filter at the same time.

Photocatalyst filter

We recommend to change this filter every 3 years. (*subject to air quality and hours used)

WPA100 Desktop Air Purifier:

WPA100 3 IN 1 Filter

Recommended to be replaced every 6-12 months or after 1600hrs of use. (*subject to air quality and hours used)

The time for filters to be replaced can differ due to the air quality and amount of hours the filter is in operation. Generally speaking, the air quality in Australia is good, however, the quality does differ in different parts of the country, you can check the HEPA filter by assessing the cleanliness, if it is looking discoloured, it is time to change it.

Replace when visible wear or discolouration occurs.

  1. Pre-Filter – Uses a micron mesh filter, which blocks 2.5mm particle matter > 99.9%. Air can be cleaned effectively, preventing contaminants such as dirt, hair, pet fur, dander, and course dust from entering the air purifier. The Pre-Filter protects all the filters and prolongs their life.
  2. HEPA (H13) Filter – The rate of removing 99.9% of minor particles as small as 0.3 microns in diameter from the air, preventing the spread of allergens and bacteria such as pollen, smog, and germs.
  3. Activated Carbon Filter – Used to remove common household contaminants such as odours, second-hand smoke, and gas pollutants.
  4. Photocatalyst Filter – Uses ultraviolet light to remove chemicals such as formaldehyde, toluene, xylene, ammonia, TVOC and other pollutants.
  5. Ionizer (Anion Generator) – Produces large amounts of negative ions (or anions) to remove airborne pollutants from the air, eliminating odours with strong absorption. The negative ions (or anions) will make bacteria lose their activity, rendering them harmless.
  6. UV Lights – Combined with photocatalyst filter, UV light creates highly effective sterilisation which kills a variety of common viruses (including influenza), bacteria and germs.
