This would depend on each user, but can be generalized with sufficient data. Filtering can be measured by average hours wasted. If filtering can give a user a relevant article of news within x amount of time, then it the user saves normal - x amount of time. If you multiply this by their hourly salary, then you get a good grasp of monetary amount. Get statistics regarding the ratio of money saved/hours saved vs paying amount and you probably get a good idea of pricing and the amount of people that would pay.

Ideally, I would get all news/articles relevant to me within 10 minutes and this would probably save me 50 minutes every day. Personally, I would pay if the service if saved me a significant amount of time and had the absence of articles of which I was not interested.
