It usually gets dirty and is a good idea to clean it every now and then.. esp with a filter like you have there. Those filter doent filter out as well as the paper ones do, but thats for air flow reasons..

I would disconnect your battery again, and clean the MAF sensor. then put it back. Your ecu should reset your learned driving habbits.. You MAY feel a throttle response difference but unlikely. But it doesnt hurt to clean it.

you mean that i have to clean the shiny part in the sensor followed by disconnecting the battery ,, so that i MAY feel some improvement ,,, but you are not sure that i'll feel improvement in acceleration ? ? right ?
