As few as possible to just get the combos down to a number that can be afforded and that will also produce a profit, overfiltering has before many times eliminated the winning number.
Also, some filters are more reliable than others, but mostly they depend upon or on the criterion by which and how they are used.
I am hardly finished with filters, if anything, I am just beginning with them.
I put 6 to 10 filters, but sometimes have used fewer and more.
I don't think that I have ever used more than 20 at one time, but I don't remember, I do have very many filters, but try to never use way too many at the same time or together, some I can't use at all, because of lack of filter software for them and or statistics for them (for their use).
