I see you are posting from Canada, which just coincidentally is the home
of visibledust.com. I'm not implying that you are a sock puppet for that
company, but it /is/ an interesting coincidence.

You say that "bristle brushes" can damage low pass sensors. You are
spreading FUD, aren't you? A hog's hair bristle brush used for oil
painting is indeed a harsh item, but we are not discussing that sort of
"bristle" brush here. We are taking about soft nylon hairs, such as may
be found in synthetic brushes.

So, now, on what basis do you state that soft nylon hairs can "damage" a
plastic filter? I'm just tickled pink that you are here, saying these
things. Please continue ...
