There is no stopping of the dust. However, you can slow it down; but ultimately, your goal should be taking pictures not worrying about the dust.

Dust can be minimized by fewer lens changes, pointing the camera down during the lens changes, not changing lenses in dusty environments, not using the camera in dusty environments.

However, the better thing to do is to use the camera as you will and just clean the sensor as needed. A rocket blower will help remove the loose dust. A wet cleaning will be needed for the rest. There are good products and tutorial at
