Can we scientifically remove all air pollution from earth?

As the title states, is it even possible to remove hazardous air chemicals in Earth?

I think I could list the pollutants which I think we could remove, these are the following :

• Nitrogen oxides (NOx)
• Carbon monoxide (CO)
• Sulfur dioxide (SO2)

I was watching The Day the Earth Stood Still, the scene where the robot became some sort of bug that "cleans" anything from its path, If that happens, even if humans were removed from the face of the earth, there will still be pollution in the atmosphere (am I right here?). And is it even possible to use the same method to destroy the chemicals found in our air?

EDIT:

I'm also thinking that If you remove these chemicals, you also remove oxygen in the atmosphere, is it even possible to filter these elements?
