Why Choose an Air Purifier Appliance?

Air pollution isn’t just an outdoor issue — Australians spend nearly 90% of their time indoors, where pollutant concentrations can be 2–5 times higher than outside1. That’s where air purifiers come in. These appliances remove airborne contaminants like:

• Dust and pollen
• Pet dander and mould spores
• Smoke and VOCs (volatile organic compounds)
• Bacteria and viruses

An air purifier or air cleaner purifier can dramatically improve your home’s air quality, especially if you live near bushfire-prone areas, have allergies, or own pets.

Key Benefits of Using an Air Purifier

• Relieves allergy and asthma symptoms
• Reduces spread of airborne germs
• Eliminates odours and chemical fumes
• Improves sleep and wellbeing

According to Asthma Australia, HEPA-filter air purifiers are recommended for reducing exposure to airborne allergens and irritants.

Features to Look for When Buying Air Purifiers Online

With so many options on the market, here are the most important features to look for when shopping for an air purifier online:

✔ CADR Rating

Clean Air Delivery Rate (CADR) indicates how effectively the purifier removes smoke, pollen, and dust. The higher the CADR, the faster the purifier works.

✔ Room Size Compatibility

Check the maximum room size the unit is designed for — from small bedrooms (up to 20m²) to large open-plan living spaces.

✔ HEPA Certification

Look for “True HEPA” filters rather than “HEPA-type” for better performance.

✔ Noise Level

Some air purifiers operate quietly below 30 decibels, while others may hum at 50+ dB — an important factor for bedrooms or offices.

✔ Smart Features

Modern appliance air purifiers include Wi-Fi control, air quality sensors, and app connectivity for remote operation.

✔ Filter Replacement Alerts

Automatic reminders make maintenance easier so your unit always performs at its best.

How Air Purifiers Work

An air purifier appliance draws air through multiple layers of filters. The most common types include:

1. HEPA Filters

High-Efficiency Particulate Air (HEPA) filters trap 99.97% of particles as small as 0.3 microns — including dust, smoke, and microbes.

2. Activated Carbon Filters

These filters absorb odours, gases, and VOCs. Ideal for homes with smokers, pets, or strong chemical use.

3. UV-C Light Purifiers

UV light kills airborne viruses and bacteria, adding an extra layer of protection against germs.

4. Ionisers

Ionisers release negatively charged ions that attract and remove pollutants from the air. However, some may emit ozone — so check safety certifications.When choosing an appliances online air purifier, make sure it matches the room size and has appropriate filters for your needs.
