CN Article on Lunar Observing

One question: in the article he extols the benefits of a moon filter, making it sound like an almost essential accessory. How many of you actually use a filter each time you observe the moon? I rarely do anymore these days; I guess I've just adjusted to the moon's brightness and don't find it overpowering, especially at higher magnifications. I'm curious if everyone else uses on, though. I will say they provide a more pleasing view at powers low enough to frame the entire moon in the field of view.

I also use it when using the Moon during later phases as a target for outreach.

Never and I've been a long time and frequent lunar observer.
The author also states that "... will impair your vision during your viewing session long after you look away from the eyepiece". But, when you look away from the eyepiece you are no longer in a viewing session

It can also make a difference how much ambient light there is where you observe. Sometimes I observe underneath a street light, and since my eyes aren't very dark adapted, the moons brightness doesn't bother me.
Many factors can affect the need or lack of need for a moon filter.
