  • Air filtration device
    Patent number: 8252100
    Abstract: An air purifier has a housing with an inlet for receiving air and an outlet for exhausting air. The housing provides an air flow path for the flow of air in a downstream direction, from the inlet towards the outlet. Particulate pre-filtration is located within the housing downstream from the air inlet. VOC pre-filtration is located within the housing downstream from the particulate pre-filtration. UV filtration is located within the housing downstream from the VOC pre-filtration. VOC post-filtration is located within the housing downstream from the UV filtration. Final particulate filtration is located within the housing downstream from the VOC post-filtration.
