All that I can advice is if you go down the filter route then buy one that will have the least effect on IQ.

When you have a filter on your lens all the time, you get accustomed to the less-than-ideal performance of your lens, and don't realize that it's the filter that's coming into play. Maybe 90+% of your shots will be largely unaffected by the filter and you will get complacent that it doesn't present an IQ issue, until you encounter a lighting situation where it does, and the filter is the last thing you think of as contributing to an inferior result.

As far as cleaning my lenses goes, I almost never do this - except with a rocket blower (unless I get the very rare finger smudge or something on it). Habitual wiping of the lens before or after use is totally unnecessary. A little loose dust, or even a scratch or two, on the front element will have absolutely no effect on your images (fisheye lenses excluded, maybe), as this guy proved conclusively. Dust on the rear element is more likely to cause a problem, and we don't use filters there
