This paper develops an impulsive SUI model with infection age for HIV. Firstly the basic reproduction number, which depends on the impulsive HIV-finding period and the HIV-finding proportion, is obtained by mathematical analysis. Secondly there exists a globally asymptotically stable infection- free equilibrium when the basic reproduction number is less than one. Therefore the HIV epidemic is theoretically cleared if we have the suitable HIV-finding proportion and the impulsive HIV-finding period such that the basic reproduction number is less than one.
