iHastek air purifier uses a six stage air purification system to help purify the air that passes through the filter:
STAGE 1 - The air first enters the Pre-filter, capturing larger particles and extending the life of the filter.
STAGE 2 - HEPA Filter removes 99% of airborne particles as small as 0.3 microns such as germs, viruses, bacteria and fungi, dust, pollen, pet dander, smoke from air passing through the filter.
STAGE 3 - Activated Carbon Filter absorbs and eliminates common household odors, such as garbage or nursery smells.
STAGE 4 - Photocatalytic Oxidation (PCO) Filter removes Volatile Organic Compounds (VOCs) and odours including toxic fumes and chemicals such as paint and new carpet fumes.
STAGE 5 - UV Bulb destroys germs, viruses, bacteria and fungi.
STAGE 6 - Ionizer releases negative ions to bind with airborne dust forming larger particles that are more easily captured by the HEPA filter.
