HEPA & Filtration FAQs
What is a HEPA filter?
HEPA stands for High Efficiency Particulate Air. HEPA filters use a dense filter material designed to capture very small airborne particles.
Purified Air Australia’s HEPA information explains that True HEPA H13 filters have a minimum efficiency of 99.95% for particles down to 0.3 micrometres.
What is the difference between HEPA and activated carbon filtration?
HEPA filtration primarily targets airborne particles such as dust, pollen and fine particulate matter.
Activated carbon is designed to absorb gases, odours and certain volatile organic compounds (VOCs).
Using both technologies together provides complementary particle and odour/gas filtration.
What is a pre-filter?
A pre-filter is the first filtration stage in many air purifiers. It captures larger particles such as dust, hair and other debris before air reaches the main filters.
Keeping the pre-filter clean can help protect the main filtration system and maintain performance.
What is CADR?
CADR stands for Clean Air Delivery Rate. It indicates the volume of cleaned air an air purifier can deliver.
A higher CADR generally means the purifier can clean a larger volume of air more quickly, making CADR an important specification when choosing an air purifier for a particular room. For assistance, please call Purified Air Australia’s helpline on 1300 571 671.
Does a higher CADR mean a better air purifier?
Not necessarily. The right CADR depends on the size and characteristics of the space.
A very high-CADR purifier may be unnecessary for a small bedroom, while a low-CADR model may not be suitable for a large open-plan living area.
The best choice combines appropriate CADR, filtration technology, room size, noise level and your specific air-quality requirements. For assistance, please call Purified Air Australia’s helpline on 1300 571 671.
