What filter should I use to see the Moon better in the daytime?

There aren't any. The problem is that daylight is not narrow-band, 'line emission', but continuum emission. Any filter you would try to use would cut down on the brightness of the Moon in the same proportion as it does the atmosphere so the relative contrast and visibility of the Moon would be essentially unchanged. At least so far as I know!
