I echo what Lincoln said as loudly as I can without typing in all caps. If you enable filtering and you get a second path somehow or somewhere (customers can be very helpful by doing "stuff" when you're not looking), you will loop up your entire network. This will happen at 3 am 2 years from now on a Sunday when you're out of town and your front line tech is asleep in a hut somewhere. Trust me. BPDU-filter bad. Really.
