Jason, the first one is a CCD filter - says so in the listing's title. CCD filters are are not intended for visual but optimised for an even tighter through pass & in a band width we can't see well if at all.

The second one you linked to is a visual filter. The Hb will help with spotting nebulae like the Horsehead neb, something normally only had in UHC type filters. It is a very good filter & represents great value for money.
