Abstract
An air sterilization device with low aerosol bounce includes an air conditioning pipe, a porous filter media, and a UV light generator. This porous filter media, it is secured on the fixing portion. This porous filter media has many irregularly distributed channels. The channel is coated with a coating layer having a thickness between 10 μm to 1000 μm sticking aerosols for avoiding bounce effect. The UV light generator can emit UV light to kill biological aerosols. It is suitable for long-term usage. So, the bounce effect of aerosols can be significantly reduced. The maintenance cost is low. The sterilization effect is excellent. Plus, the flow rate of the air conditioning system remains high.
