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 ?m to 1000 ?m 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.

Abstract: A multi-stage horizontal elutriator includes a flow inlet, a flow outlet, a hollow container that is disposed between said flow inlet and said flow outlet. This hollow container has a guide-in portion, a first parallel plates set, a second parallel plates set, and a guide-out portion. The first plates set is different to the second plates set. So, the aerosol's falling distance can be shortened significantly. The relative culturable ratio and the survival efficiency for bioaerosols are both high. The structure is simple with low cost.
