High-Efficiency Particulate Arresting filters – or HEPA filters – are known world-wide for their unique filtration process.
HEPA filters are recommended for asthma and allergy sufferers. They have a three-stage filtration system that removes aggravating particles from the air such as dust, smoke, pollen, animal dander, and chemical odours and gases.
HEPA’s three-stage filtration process involves:
- A pre-filter that captures large particles such as dust
- A second layer that traps 99.97% of particles 0.3 microns – approximately 0.000012 inches – and larger
- The removal of off-gases and odours by a Volatile Organic Compounds (VOC) filter
