The problem is that different lenses yield different results.  You now know how your lenses react under the tested conditions with that filter.

Of course, if you really want to protect your lens from dust and moisture, the real hazard is not to the front element (that can be cleaned).  You want to keep contamination from entering the lens through the various breathing holes on the barrel (Lenses that change length when zooming/focusing need to take-in/expel air as they change their internal volume).   If your goal is protecting image quality, I would suggest protecting the barrel of the lens before worrying about the front element.
