High-Efficiency Particulate Arresting filters – or HEPA filters – are known worldwide for their unique filtration process. While it is true that many home heating and cooling systems come with a filter, these are included mainly to protect the equipment, not the people using it, and they do not effectively eliminate pollutants and contaminants. To truly keep the air in a home clean, a proper filtration or purification system is required. A HEPA filter is one of the more efficient air cleaning products available for improving indoor air quality.
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.
The HEPA three-stage filtration process:
- 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 (dust, pollen, bacteria, animal dander, attached viruses, cigarette smoke and more)
- Removal of odours and hazardous chemical by-products by a Volatile Organic Compounds (VOC) filter
