  • Tubing air purification system
    Patent number: 8608838
    Abstract: The invention provides an air purification system in form of tubing, by which particulates of various sizes in the air flow can be collected. The system includes an air inlet, an air outlet and a particulate removing unit located therebetween, the particulate removing unit including a tubing array of material having low dielectric constant, when an air flow passes through the system electrostatic effect is created between the air flow and the tubing material so as to remove the particulates entrained within the air flow. The invention also provides a method for removing particulates from air flow using the electrostatic effect created between the air flow and said material.
