HEPA Air Purifiers & Air Filters

An air purifier is an essential choice if you’re worried about the quality of air you’re breathing in. These room purifiers are suitable for indoor use and can be used in the home, office or workplace. They will purify the air in the room, and help to recirculate this cleaner air.

What Does an Air Purifier Do?

An air purifier improves the quality of air indoors by removing tiny contaminants such as allergens, pollutants and viruses. It can also help to ease or remove unpleasant odours, keeping your rooms fresher.

Air purifiers are particularly useful if you suffer from allergies. If you open a window to let fresh air in, you may also allow allergens from outside to enter. Using an air cleaner is one way to avoid this, as it will treat the air that’s already in the room and encourage it to circulate. This can be very helpful if you’re suffering from pollen or dust allergies.

What is a HEPA Filter?

A HEPA filter is a high-quality filter capable of removing 99.97% of the airborne particles from the air within a room. HEPA stands for High Efficiency Particulate Air Filter – filters that meet this standard can capture incredibly small particles down to just 0.3 microns in size.

When you choose a HEPA air purifier, you know its filter has been tested and approved to this high standard. It will efficiently remove pollutants, allowing you to breathe in far cleaner and healthier air.

 

Benefits of a HEPA Air Purifier

A HEPA air purifier is one of the most effective ways to improve indoor air quality. Key benefits include:
- Removes up to 99.97% of airborne particles including dust, pollen, pet dander and mould spores
- Reduces allergy and asthma symptoms by filtering out common triggers
- Captures fine particles as small as 0.3 microns — far smaller than the human eye can see
- Helps eliminate household odours from cooking, pets and smoking
- Circulates cleaner, fresher air throughout the room continuously

Choosing an Air Purifier for Your Room Size

Matching the purifier to your room size ensures effective air cleaning. Most models state a maximum room coverage area in square metres. For a small bedroom or home office, a compact unit with a CADR (Clean Air Delivery Rate) of around 100 m³/hr is usually sufficient. For open-plan living areas and larger rooms, look for units rated at 200 m³/hr or above. Running the purifier continuously on a low setting provides the most consistent air quality.
