Dust :(

First off, I know I should post to the Samsung DSLR sub forum but I believe this is relevant to be in here as the Samsung and K20D have the same functions for this, or so I am told.

On three different lenses I get two very visable specs of dust in the same place every time but they're not visible in the viewfinder. To me this would initially send me straight to the sensor for a dust check. I run the dust check and it shows the white screen with no apparent black marks. Even looking in the same area (flipped upside down) as they appear on the images there's still no marks indicating dust on my sensor. So I run the sensor clean whilst my camera is inside my mini macro studio (I am told this is the least likely place for dust transfer) and inspect the sensor with a magnifying glass. I see no dust/dirt/anything what so ever on my sensor. Am I missing it? Can it appear on an image bigger than it actually is? I used a rocket blower with one blast of air but it is still there. What can I do other than take it for cleaning?

Someone has told me that when the door opens to reveal the sensor, that there's two filters covering it so I can use a brush, I do NOT want to put a brush anywhere near the sensor.

Can anyone help/offer tips?

I wouldn't put a brush anywhere near my sensor either.
You should probably do a wet cleaning though.
There are kits available for doing this.

Use your rocket blower again, but this time blow as hard and for as long as your hand allows. Should work well, particularly for the GX-10 and GX-20.
The blower will cause no harm to the sensor but touching it even once with just about anything will.
