A hand held shower head with filter replacing pre-display device comprises a round recess socket with hoop female threads created into the reverse side of a shower head shell to let an alerting pod screwing mesh therein. A signal circuit device is embedded in the alerting pod for measuring and displaying function. The alerting pod can be either screwing meshed into the recess socket for normal measuring and alerting function or screwing detached off the recess socket for battery recharging operation. Thereby, not only the shower head shell can be adequately powered but also the alerting pod can be separated out of the shower head shell for independently recharging operation so that shower head shell is unnecessary to discarded and replaced even the power supply in the signal circuit device is running out. Thus, it not only saves resource waste but also conserves economical expense incurred by frequent replacement of the shower head shell.
