The biggest filter is your eyelashes!!!
If you want to look you will.
If you stop and prevent yourself from looking you won’t look.
Come on! What about self control?
Okay, I know it can be addictive and perverted people will continue watching whatever they want regardless of having filtered internet.
There are psychiatrists/psychologists who specialize with these specific addictions.
The majority of men(or women) will not need these filters.
