It is commonly associated that air pollution refers mainly to outdoor environmental factors such as vehicle exhaust fumes, smog, smoke from bushfires, pollution and pollens.
Environmental protection agencies in Australia have worked to improve air quality. With the exception of natural disasters like bushfires, generally, the external air quality is good and there is no need for concern about long-term effects of air pollution.
Indoor air quality in homes and office buildings is also important to consider, as it may pose health risks to occupants.
Exposure to indoor pollutants is prevalent in today’s society, as we spend most of our time inside. Long term exposure to air pollution indoors can be a major source of risk factors towards adverse health effects such as decreased cognitive function in the form of headaches, fatigue and nausea due to the air pollutant concentrations found in the indoor environment of some homes and offices. These pollutants can be either man-made or natural and can affect human health.
Air pollution levels in our indoor environment are affected by natural pollutants like airborne viruses (including influenza and COVID-19), allergens, dust, animal fur, mites, mould, pollen, and bushfire smoke. Man-made culprits such as chemicals in cleaning agents, perfumes and furniture manufacturing also contribute. Cooking appliances like gas stovetops and open fireplaces are additional sources of indoor air pollution.
Exposure to indoor pollution can lead to adverse health effects in both the short and long term.
Air purifiers used indoors can offer a level of protection against the exposure to air pollutants.
While mechanical ventilation such as opening a window can help. Air purifiers are designed to eliminate pollutants and contaminants from indoor air without letting in outdoor pollutants. They operate by drawing air through filters that capture particles such as dust, pollen, pet dander, and VOC emissions from household products and chemicals, resulting in a cleaner and healthier environment.
Indoor air purifiers are effective in mitigating the harmful effects of indoor air pollution. They are capable of minimising airborne particles, pollutants, and unpleasant odours, thus enhancing the overall quality of the air. With their ability to eliminate contaminants, air purifiers contribute to a cleaner and healthier environment for you and your loved ones.
Here, we are discussing air purifiers that meet certain standards for quality.
To improve indoor air quality, it’s important to install an air purifier with a HEPA filter. HEPA filters trap 99.7% of particles in the air that are 0.3 microns or larger. They’re great for reducing indoor air pollution by capturing particles like dust, pet dander, mould spores, smoke, pollen and other dangerous substances. Installing air purifiers with HEPA filters can help lower indoor air pollutant levels, creating a healthier and safer environment.
The Welcare PureAir range includes three air purifiers that feature a HEPA 13 filter, offering high-quality protection against environmental hazards for you and your loved ones.
UV technology is effective in reducing airborne viruses, bacteria, and mould spores. Air purifiers commonly use this technology. UV light breaks down the outer walls of bacteria and viruses, making them harmless. This helps in reducing the spread of infectious diseases and illnesses like influenza. The filtered air is then free from contagious pathogens.
The Welcare PureAir range features two air purifiers equipped with UV lights.
The quality of the air we breathe indoors can affect our wellbeing. The Welcare PureAir Household Air Purifier uses a 6 Stage Air Purification System, including HEPA (H13) filter, UV Light, and photocatalyst technology to purify the air comprehensively.

This air purifier is perfect for people who have pets, allergies, live in areas with bushfire or pollution, or just want a fresh, clean, and healthy home or office environment.
This air purifier has a 6 stage HEPA (H13) Air Purification system. The first stage is a Pre-Filter that uses a micron mesh filter. It blocks 2.5mm particle matter > 99.9%, preventing contaminants such as dirt, hair, pet fur, dander, and course dust from entering the air purifier. The Pre-Filter protects all the subsequent filters and prolongs their life.
The HEPA (H13) Filter is highly efficient and can remove minor particles as small as 0.3 microns in diameter from the air. This helps prevent the spread of allergens, bacteria, and other harmful substances like pollen, mould spores, smog, and germs.
The Activated Carbon Filter is designed to eliminate household contaminants, including odours, second-hand smoke, and gas pollutants.
The Photocatalyst Filter utilises ultraviolet light to eliminate various pollutants, including formaldehyde, toluene, xylene, ammonia, and TVOC.
An ionizer, also known as an anion generator, generates negative ions to remove airborne pollutants and absorb odours. The negative ions also have the ability to render bacteria harmless by reducing their activity.
The combination of two UV lights and a photocatalyst filter results in effective sterilisation that can eliminate a range of common bacteria and germs.
This air purifier is designed for large areas up to 40-50m2, such as an average sized living room of 25m2. It effectively filters dust, pollen, smoke, germs, and bacteria while also removing odours.

The inactivation rate of SARS-CoV-2 was tested and found to be 99.95% or higher within a 30-second time frame.
Air purifiers are useful for people with allergies or asthma as they can remove common allergens such as pollen, dust mites, and pet dander, resulting in better respiratory health and reduced allergy symptoms.
Individuals with asthma have a heightened sensitivity to airborne triggers. The use of air purifiers can aid in the removal of asthma triggers, including dust, mould spores, and smoke particles. As a result, the frequency and severity of asthma attacks may be reduced.
Viruses, such as influenza and COVID-19, can be transmitted through droplets in the air when an infected person coughs, sneezes, breathes, or talks. It’s important to note that these droplets can remain in the air for up to an hour. An effective air purifier can help in this situation. However, when the virus particles land on surfaces in the home, handwashing and sanitising are crucial in preventing the spread of the flu.
Air purifiers that come with activated carbon filters have the capability to remove unpleasant smells caused by cooking, smoking, pets, and chemical fumes.
The answer is affirmative, given specific requirements are met.
