'Blocker' is derived from the English verb 'to block' and given the German ending '-er'. So it always refers to a person or thing that blocks or inhibits something.

filter
'der Filter' and 'der Blocker' can both make sure that certain content does not get through in technology. A 'Filter' sorts or selects according to certain rules. It can clean, display, change, or hold something back. A 'Blocker' stops certain content completely, for example ads in a browser. So a blocker can be a kind of filter, but not every filter is a blocker. The words are easily confused because both can sort something out. 'Filter' sounds more general; 'Blocker' fits especially when something is actively blocked.
Der Blocker verhindert, dass auf der Webseite ständig Werbung erscheint.
