The Jnet Mehadrin Filter comes in three levels:
1.) Least sensitive - Begins blocking (i.e. blacking out or otherwise distorting) when a picture is 5% skin, blocks pictures completely if they are at least 25% skin.
2.) Intermediate Level - Begins blocking when a picture is 2% skin, blocks completely at 17%.
3.) Most sensitive - Begins blocking when a picture is 1% skin, blocks completely at 10%.
I started off with the intermediate level Mehadrin Filter. However, my wife is complaining that it's blocking pictures too much, making it difficult for her to shop online for clothing. Therefore, I am now trying the least sensitive level, which still blocks virtually all inappropriate pictures, while, hopefully, making things easier for my wife.
