How to reduce single pixels noise in image?

[andyf65867865]

Is there a way to reduce 1 pixels noise not bluring the whole image. That way I do not like "dust and scratch" because of bluring.

Could you please post the image in question? 

Just to make sure: Which settings have you tried for Dust > Scratches?

On the marked areas we can see some blurring and details degradation.

I wonder if there is an easy way other than a dust and scratch filter?

And I wonder why you won’t post the image already? 

The loss in the screenshot you posted does not seem catastrophic to me; naturally I don’t know what the exact requirements are.

Is this for research/academic purposes? 

Which other Filters have you tried (Smart Blur, …)? 

Have you considering using alternative software (Topaz, …)?
