Do luxury resorts use filtered water to wash salad vegetables.

Yes, highly reputable luxury five star resorts and top tier tourist restaurants meticulously wash all their fresh salad vegetables and fruits using heavily filtered, purified water specifically to prevent foreign tourists from getting stomach bugs. In these high end environments, eating raw salads is generally considered perfectly safe. However, you must still strictly avoid raw salads at small, rustic street side cafes, as they almost certainly use unfiltered tap water.
